Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Breaking changes to any of the following will cause the minor version to be incremented (as long as this project is 0.x). Only these pieces are considered part of the public API:

  • The behavior of the generated code. Specifically, the way in which generated endpoints and classes are called and the way in which those calls communicate with an OpenAPI server. Any other property of the generated code is not considered part of the versioned, public API (e.g., code formatting, comments).
  • The invocation of the CLI (e.g., commands or arguments).

Programmatic usage of this project (e.g., importing it as a Python module) and the usage of custom templates are not considered part of the public API and therefore may change behavior at any time without notice.

The 0.x prefix used in versions for this project is to indicate that breaking changes are expected frequently (several times a year). Breaking changes will increment the minor number, all other changes will increment the patch number. You can track the progress toward 1.0 here.

0.19.1 (2024-03-27)

Features

Add config option to override content types

You can now define a content_type_overrides field in your config.yml:

content_type_overrides:
  application/zip: application/octet-stream

This allows openapi-python-client to generate code for content types it doesn't recognize.

PR #1010 closes #810. Thanks @gaarutyunov!

Fixes

Add aliases to Client for pyright

This should resolve incompatibilities between the generated Client class and the pyright type checker.

PR #1009 closes #909. Thanks @patrick91!

0.19.0 (2024-03-06)

Breaking Changes

Update PDM metadata syntax

Metadata generated for PDM will now use the new distribution = true syntax instead of package-type = "library". New packages generated with --meta pdm will require PDM 2.12.0 or later to build.

Features

Add response content to UnexpectedStatus exception

The error message for UnexpectedStatus exceptions will now include the UTF-8 decoded (ignoring errors) body of the response.

PR #989 implements #840. Thanks @harabat!

Fixes

Allow hyphens in path parameters

Before now, path parameters which were invalid Python identifiers were not allowed, and would fail generation with an "Incorrect path templating" error. In particular, this meant that path parameters with hyphens were not allowed. This has now been fixed!

PR #986 fixed issue #976. Thanks @harabat!

Warning

This change may break custom templates, see this diff if you have trouble upgrading.

0.18.0 (2024-02-22)

Breaking Changes

For custom templates, changed type of endpoint parameters

This does not affect projects that are not using --custom-template-path

The type of these properties on Endpoint has been changed from Dict[str, Property] to List[Property]:

  • path_parameters
  • query_parameters
  • header_parameters
  • cookie_parameters

If your templates are very close to the default templates, you can probably just remove .values() anywhere it appears.

The type of iter_all_parameters() is also different, you probably want list_all_parameters() instead.

Updated generated config for Ruff v0.2

This only affects projects using the generate command, not the update command. The pyproject.toml file generated which configures Ruff for linting and formatting has been updated to the 0.2 syntax, which means it will no longer work with Ruff 0.1.

Updated naming strategy for conflicting properties

While fixing #922, some naming strategies were updated. These should mostly be backwards compatible, but there may be some small differences in generated code. Make sure to check your diffs before pushing updates to consumers!

Features

support httpx 0.27 (#974)

Fixes

Allow parameters with names differing only by case

If you have two parameters to an endpoint named mixedCase and mixed_case, previously, this was a conflict and the endpoint would not be generated. Now, the generator will skip snake-casing the parameters and use the names as-is. Note that this means if neither of the parameters was snake case, neither will be in the generated code.

Fixes #922 reported by @macmoritz & @benedikt-bartscher.

Fix naming conflicts with properties in models with mixed casing

If you had an object with two properties, where the names differed only by case, conflicting properties would be generated in the model, which then failed the linting step (when using default config). For example, this:

type: "object"
properties:
  MixedCase:
    type: "string"
  mixedCase:
    type: "string"

Would generate a class like this:

class MyModel:
    mixed_case: str
    mixed_case: str

Now, neither of the properties will be forced into snake case, and the generated code will look like this:

class MyModel:
    MixedCase: str
    mixedCase: str

0.17.3 (2024-02-20)

Fixes

Remove spurious field_dict.update({}) for types without properties (#969)

Fix invalid type check for nested unions

Nested union types (unions of unions) were generating isinstance() checks that were not valid (at least for Python 3.9).

Thanks to @codebutler for PR #959 which fixes #958 and #967.

0.17.2 (2024-01-15)

Features

Add --meta=pdm option for generating PEP621 + PDM metadata

The default metadata is still --meta=poetry, which generates a pyproject.toml file with Poetry-specific metadata. This change adds the --meta=pdm option which includes PDM-specific metadata, but also standard PEP621 metadata. This may be useful as a starting point for other dependency managers & build tools (like Hatch).

Add original OpenAPI data attribute to Response object

PR #767

In custom templates, you can now access a response.data attribute that contains the original OpenAPI definition of the response (Response Object or Reference Object).

Include the UP rule for generated Ruff config

This enables pyupgrade-like improvements which should replace some .format() calls with f-strings.

Fixes

Fix Ruff formatting for --meta=none

PR #940 fixes issue #939. Thanks @satwell!

Due to the lack of pyproject.toml, Ruff was not getting configured properly when --meta=none. As a result, it didn't clean up common generation issues like duplicate imports, which would then cause errors from linters.

This is now fixed by changing the default post_hook to ruff check . --fix --extend-select=I when --meta=none. Using generate --meta=none should now be almost identical to the code generated by update.

0.17.1 (2024-01-04)

Features

Export Unset types from generated types.py (#927)

Generate properties for some boolean enums

If a schema has both type = "boolean" and enum defined, a normal boolean property will now be created. Previously, the generator would error.

Note that the generate code will not correctly limit the values to the enum values. To work around this, use the OpenAPI 3.1 const instead of enum to generate Python Literal types.

Thanks for reporting #922 @macmoritz!

Fixes

Do not stop generation for invalid enum values

This generator only supports enum values that are strings or integers. Previously, this was handled at the parsing level, which would cause the generator to fail if there were any unsupported values in the document. Now, the generator will correctly keep going, skipping only endpoints which contained unsupported values.

Thanks for reporting #922 @macmoritz!

Fix lists within unions

Fixes #756 and #928. Arrays within unions (which, as of 0.17 includes nullable arrays) would generate invalid code.

Thanks @kgutwin and @diesieben07!

Simplify type checks for non-required unions

0.17.0 (2023-12-31)

Breaking Changes

Removed query parameter nullable/required special case

In previous versions, setting either nullable: true or required: false on a query parameter would act like both were set, resulting in a type signature like Union[None, Unset, YourType]. This special case has been removed, query parameters will now act like all other types of parameters.

Renamed body types and parameters

PR #900 addresses #822.

Where previously there would be one body parameter per supported content type, now there is a single body parameter which takes a union of all the possible inputs. This correctly models the fact that only one body can be sent (and ever would be sent) in a request.

For example, when calling a generated endpoint, code which used to look like this:

post_body_multipart.sync_detailed(
    client=client,
    multipart_data=PostBodyMultipartMultipartData(),
)

Will now look like this:

post_body_multipart.sync_detailed(
    client=client,
    body=PostBodyMultipartBody(),
)

Note that both the input parameter name and the class name have changed. This should result in simpler code when there is only a single body type and now produces correct code when there are multiple body types.

Features

OpenAPI 3.1 support

The generator will now attempt to generate code for OpenAPI documents with versions 3.1.x (previously, it would exit immediately on seeing a version other than 3.0.x). The following specific OpenAPI 3.1 features are now supported:

  • null as a type
  • Arrays of types (e.g., type: [string, null])
  • const (defines Literal types)

The generator does not currently validate that the OpenAPI document is valid for a specific version of OpenAPI, so it may be possible to generate code for documents that include both removed 3.0 syntax (e.g., nullable) and new 3.1 syntax (e.g., null as a type).

Thanks to everyone who helped make this possible with discussions and testing, including:

  • @frco9
  • @vogre
  • @naddeoa
  • @staticdev
  • @philsturgeon
  • @johnthagen

Support multiple possible requestBody

PR #900 addresses #822.

It is now possible in some circumstances to generate valid code for OpenAPI documents which have multiple possible requestBody values. Previously, invalid code could have been generated with no warning (only one body could actually be sent).

Only one content type per "category" is currently supported at a time. The categories are:

  • JSON, like application/json
  • Binary data, like application/octet-stream
  • Encoded form data, like application/x-www-form-urlencoded
  • Files, like multipart/form-data

Fixes

Always use correct content type for requests

In previous versions, a request body that was similar to a known content type would use that content type in the request. For example application/json would be used for application/vnd.api+json. This was incorrect and could result in invalid requests being sent.

Now, the content type defined in the OpenAPI document will always be used.

0.16.1 (2023-12-23)

Features

Support httpx 0.26 (#913)

0.16.0 (2023-12-07)

Breaking Changes

Switch from Black to Ruff for formatting

black is no longer a runtime dependency, so if you have them set in custom post_hooks in a config file, you'll need to make sure they're being installed manually. ruff is now installed and used by default instead.

Use Ruff instead of isort + autoflake at runtime

isort and autoflake are no longer runtime dependencies, so if you have them set in custom post_hooks in a config file, you'll need to make sure they're being installed manually. ruff is now installed and used by default instead.

Features

Support all text/* content types in responses

Within an API response, any content type which starts with text/ will now be treated the same as text/html already was—they will return the response.text attribute from the httpx Response.

Thanks to @fdintino for the initial implementation, and thanks for the discussions from @kairntech, @rubenfiszel, and @antoneladestito.

Closes #797 and #821.

Support application/octet-stream request bodies

Endpoints that accept application/octet-stream request bodies are now supported using the same File type as octet-stream responses.

Thanks to @kgutwin for the implementation and @rtaycher for the discussion!

0.15.0 (2023-07-23)

Breaking Changes

Minimum httpx version raised to 0.20

Some features of generated clients already failed at runtime when using httpx < 0.20, but now the minimum version is enforced at generation time.

Connections from clients no longer automatically close (PR #775)

Client and AuthenticatedClient now reuse an internal httpx.Client (or AsyncClient)—keeping connections open between requests. This will improve performance overall, but may cause resource leaking if clients are not closed properly. The new clients are intended to be used via context managers—though for compatibility they don't have to be used with context managers. If not using a context manager, connections will probably leak. Note that once a client is closed (by leaving the context manager), it can no longer be used—and attempting to do so will raise an exception.

APIs should now be called like:

with client as client:
    my_api.sync(client)
    another_api.sync(client)
# client is closed here and can no longer be used

Generated READMEs reflect the new syntax, but READMEs for existing generated clients should be updated manually. See this diff for inspiration.

Generated clients and models now use the newer attrs @define and field APIs

See the attrs docs for more information on how these may affect you.

Removed public attributes for Client and AuthenticatedClient

The following attributes have been removed from Client and AuthenticatedClient:

  • base_url—this can now only be set via the initializer
  • cookies—set at initialization or use .with_cookies()
  • headers—set at initialization or use .with_headers()
  • timeout—set at initialization or use .with_timeout()
  • verify_ssl—this can now only be set via the initializer
  • follow_redirects—this can now only be set via the initializer

The timeout param and with_timeout now take an httpx.Timeout instead of a float

AuthenticatedClient no longer inherits from Client

The API of AuthenticatedClient is still a superset of Client, but the two classes no longer share a common base class.

Features

Allow customizing the underlying httpx clients

There are many use-cases where customizing the underlying httpx client directly is necessary. Some examples are:

The new Client and AuthenticatedClient classes come with several methods to customize underlying clients. You can pass arbitrary arguments to httpx.Client or httpx.AsyncClient when they are constructed:

client = Client(base_url="https://api.example.com", httpx_args={"proxies": {"https://": "https://proxy.example.com"}})

The underlying clients are constructed lazily, only when needed. httpx_args are stored internally in a dictionary until the first request is made.

You can force immediate construction of an underlying client in order to edit it directly:

import httpx
from my_api import Client

client = Client(base_url="https://api.example.com")
sync_client: httpx.Client = client.get_httpx_client()
sync_client.timeout = 10
async_client = client.get_async_httpx_client()
async_client.timeout = 15

You can also completely override the underlying clients:

import httpx
from my_api import Client

client = Client(base_url="https://api.example.com")
# The params you put in here ^ are discarded when you call set_httpx_client or set_async_httpx_client
sync_client = httpx.Client(base_url="https://api.example.com", timeout=10)
client.set_httpx_client(sync_client)
async_client = httpx.AsyncClient(base_url="https://api.example.com", timeout=15)
client.set_async_httpx_client(async_client)

Clients now reuse connections between requests

This happens every time you use the same Client or AuthenticatedClient instance for multiple requests, however it is best to use a context manager (e.g., with client as client:) to ensure the client is closed properly.

0.9.0 - 2021-05-04

Breaking Changes

  • Some generated names will be different, solving some inconsistencies. (closes #369) (#375) Thanks @ramnes!
  • Change reference resolution to use reference path instead of class name (fixes #342) (#366)
  • If a schema references exactly one other schema in allOf, oneOf, or anyOf that referenced generated model will be used directly instead of generating a copy with another name. (#361)
  • Attributes shadowing any builtin except id and type will now be renamed in generated clients (#360, #378, #407). Thanks @dblanchette and @forest-benchling!

Features

  • Allow httpx 0.18.x in generated clients (#400)
  • Add summary attribute to Endpoint for use in custom templates (#404)
  • Support common parameters for paths (#376). Thanks @ramnes!
  • Add allOf support for model definitions (#98) (#321)

Fixes

  • Attempt to deduplicate endpoint parameters based on name and location (fixes #305) (#406)

  • Allow passing data with files in multipart. (Fixes #351) (#355)
  • Deserialization of unions (#332). Thanks @forest-benchling!

0.8.0 - 2021-02-19

Breaking Changes

  • Generated clients will no longer pass through None to query parameters. Previously, any query params set to None would surface as empty strings (per the default behavior of httpx). This is contrary to the defaults indicated by the OpenAPI 3.0.3 spec. Ommitting these parameters makes us more compliant. If you require a style of null to be passed to your query parameters, please request support for the OpenAPI "style" attribute. Thank you to @forest-benchling and @bowenwr for a ton of input on this.

Additions

  • New --meta command line option for specifying what type of metadata should be generated:

    • poetry is the default value, same behavior you're used to in previous versions
    • setup will generate a pyproject.toml with no Poetry information, and instead create a setup.py with the project info.
    • none will not create a project folder at all, only the inner package folder (which won't be inner anymore)

  • Attempt to detect and alert users if they are using an unsupported version of OpenAPI (#281).

  • The media type application/vnd.api+json will now be handled just like application/json (#307). Thanks @jrversteegh!

  • Support passing models into query parameters (#316). Thanks @forest-benchling!

  • Add support for cookie parameters (#326).

  • New --file-encoding command line option (#330). Sets the encoding used when writing generated files (defaults to utf-8). Thanks @dongfangtianyu!

Changes

  • Lowered the minimum version of python-dateutil to 2.8.0 for improved compatibility (#298 & #299). Thanks @bowenwr!
  • The from_dict method on generated models is now a @classmethod instead of @staticmethod (#215 & #292). Thanks @forest-benchling!
  • Renamed all templates to end in .jinja, and all python-templates to end in .py.jinja to fix confusion with the latest version of mypy. Note this will break existing custom templates until you update your template file names.

Fixes

  • Endpoint tags are now sanitized during parsing to fix an issue where My Tag and MyTag are seen as two different tags but are then later unified, causing errors when creating directories. Thanks @p1-ra! (#328)
  • Parser will softly ignore value error during schema responses' status code convertion from string to integer (not a number). Errors will be reported to the end user and parsing will continue to proceed (#327).
  • The generated from_dict and to_dict methods of models will now properly handle nullable and not required properties that are themselves generated models (#315). Thanks @forest-benchling!
  • Fixed a typo in the async example in generated README.md files (#337). Thanks @synchronizing!
  • Fix deserialization of None and Unset properties for all types by unifying the checks (#334). Thanks @forest-benchling!
  • If duplicate model names are detected during generation, you'll now get an error message instead of broken code (#336). Thanks @forest-benchling!
  • Fixes Enum deserialization when the value is UNSET (#306). Thanks @bowenwr!

0.7.3 - 2020-12-21

Fixes

  • Spacing and extra returns for Union types of additionalProperties (#266 & #268). Thanks @joshzana & @packyg!
  • Title of inline schemas will no longer be missing characters (#271 & #274). Thanks @kalzoo!
  • Handling of nulls (Nones) when parsing or constructing dates (#267). Thanks @fyhertz!

0.7.2 - 2020-12-08

Fixes

  • A bug in handling optional properties that are themselves models (introduced in 0.7.1) (#262). Thanks @packyg!

0.7.1 - 2020-12-08

Additions

  • Support for additionalProperties attribute in OpenAPI schemas and "free-form" objects by adding an additional_properties attribute to generated models. COMPATIBILITY NOTE: this will prevent any model property with a name that would be coerced to "additional_properties" in the generated client from generating properly (#218 & #252). Thanks @packyg!

Fixes

  • Enums will once again work with query parameters (#259). Thanks @packyg!
  • Generated Poetry metadata in pyproject.toml will properly indicate Python 3.6 compatibility (#258). Thanks @bowenwr!

0.7.0 - 2020-11-25

Breaking Changes

  • Any request/response field that is not required and wasn't specified is now set to UNSET instead of None.

  • Values that are UNSET will not be sent along in API calls

  • Schemas defined with type=object will now be converted into classes, just like if they were created as ref components. The previous behavior was a combination of skipping and using generic Dicts for these schemas.

  • Response schema handling was unified with input schema handling, meaning that responses will behave differently than before. Specifically, instead of the content-type deciding what the generated Python type is, the schema itself will.

    • As a result of this, endpoints that used to return bytes when content-type was application/octet-stream will now return a File object if the type of the data is "binary", just like if you were submitting that type instead of receiving it.

  • Instead of skipping input properties with no type, enum, anyOf, or oneOf declared, the property will be declared as None.

  • Class (models and Enums) names will now contain the name of their parent element (if any). For example, a property declared in an endpoint will be named like {endpointname}{previousclassname}. Classes will no longer be deduplicated by appending a number to the end of the generated name, so if two names conflict with this new naming scheme, there will be an error instead.

Additions

  • Added a --custom-template-path option for providing custom jinja2 templates (#231 - Thanks @erichulburd!).
  • Better compatibility for "required" (whether or not the field must be included) and "nullable" (whether or not the field can be null) (#205 & #208). Thanks @bowenwr & @emannguitar!
  • Support for all the same schemas in responses as are supported in parameters.
  • In template macros: added declare_type param to transform and initial_value param to construct to improve flexibility (#241 - Thanks @packyg!).

Fixes

  • Fixed spacing and generation of properties of type Union in generated models (#241 - Thanks @packyg!).
  • Fixed usage instructions in generated README.md (#247 - Thanks @theFong!).

0.6.2 - 2020-11-03

Fixes

  • Prefix generated identifiers to allow leading digits in field names (#206 - @kalzoo).
  • Prevent autoflake from removing __init__.py imports during generation. (#223 - Thanks @fyhertz!)
  • Update minimum Pydantic version to support Python 3.9

Additions

  • Allow specifying the generated client's version using package_version_override in a config file. (#225 - Thanks @fyhertz!)

0.6.1 - 2020-09-26

Changes

  • Use httpx ^0.15.0 in generated clients

Fixes

  • Properly remove spaces from generated Enum keys (#198). Thanks @bowenwr!

Additions

  • Endpoints without operationIds will have a name generated from their method and path (#92). Thanks @Kerybas & @dtkav!
  • autoflake will be run on generated clients to clean up unused imports / variables (#138). Thanks @pawamoy!
  • Note to README about supported OpenAPI versions (#176). Thanks @filippog!

0.6.0 - 2020-09-21

Breaking Changes

  • Reorganized api calls in generated clients. async_api will no longer be generated. Each path operation will now have it's own module under its tag. For example, if there was a generated function api.my_tag.my_function() it is replaced with api.my_tag.my_function.sync(). The async version can be called with asyncio() instead of sync(). (#167)
  • Removed support for mutable default values (e.g. dicts, lists). They may be added back in a future version given enough demand, but the existing implementation was not up to this project's standards. (#170)
  • Removed generated errors module (and the ApiResponseError therein). Instead of raising an exception on failure, the sync() and asyncio() functions for a path operation will return None. This means all return types are now Optional, so mypy will require you to handle potential errors (or explicitly ignore them).
  • Moved models.types generated module up a level, so just types.
  • All generated classes that were dataclass now use the attrs package instead

Additions

  • Every generated API module will have a sync_detailed() and asyncio_detailed() function which work like their non-detailed counterparts, but return a types.Response[T] instead of an Optional[T] (where T is the parsed body type). types.Response contains status_code, content (bytes of returned content), headers, and parsed (the parsed return type you would get from the non-detailed function). (#115)
  • It's now possible to include custom headers and cookies in requests, as well as set a custom timeout. This can be done either by directly setting those parameters on a Client (e.g. my_client.headers = {"Header": "Value"}) or using a fluid api (e.g. my_endpoint.sync(my_client.with_cookies({"MyCookie": "cookie"}).with_timeout(10.0))).
  • Unsupported content types or no responses at all will no longer result in an endpoint being completely skipped. Instead, only the detailed versions of the endpoint will be generated, where the resulting Response.parsed is always None. (#141)
  • Support for Python 3.6 (#137 & #154)
  • Support for enums with integer values

Changes

  • The format of any errors/warnings has been spaced out a bit.

0.5.5 - 2020-09-04

Fixes

  • Improved trailing comma handling in endpoint generation (#178 & #179). Thanks @dtkav!
  • Optional is now properly imported for nullable fields (#177 & #180). Thanks @dtkav!

0.5.4 - 2020-08-29

Additions

  • Support for octet-stream content type (#116)
  • Support for nullable (#99)
  • Union properties can be defined using oneOf (#98)
  • Support for lists of strings, integers, floats and booleans as responses (#165). Thanks @Maistho!

0.5.3 - 2020-08-13

Security

  • All values that become file/directory names are sanitized to address path traversal vulnerabilities (CVE-2020-15141)
  • All values that get placed into python files (everything from enum names, to endpoint descriptions, to default values) are validated and/or saniziatied to address arbitrary code execution vulnerabilities (CVE-2020-15142)

Changes

  • Due to security concerns/implementation complexities, default values are temporarily unsupported for any RefProperty that doesn't refer to an enum.
  • Defaults for properties must now be valid values for their respective type (e.g. "example string" is an invalid default for an integer type property, and the function for an endpoint using it would fail to generate and be skipped).

Additions

  • Added support for header parameters (#117)

Fixes

  • JSON bodies will now be assigned correctly in generated clients(#139 & #147). Thanks @pawamoy!

0.5.2 - 2020-08-06

Additions

  • Added project_name_override and package_name_override config options to override the name of the generated project/package (#123)
  • The generated library's version is now the same as the OpenAPI doc's version (#134)

0.5.1 - 2020-08-05

Fixes

  • Relative paths are now allowed in securitySchemes/OAuthFlow/tokenUrl (#130).
  • Schema validation errors will no longer print a stack trace (#131).
  • Invalid YAML/URL will no longer print stack trace (#128)

0.5.0 - 2020-08-05

Changes

  • When encountering a problem, the generator will now differentiate between warnings (things it was able to skip past) and errors (things which halt generation altogether).

Additions

  • The generator can now handle many more errors gracefully, skipping the things it can't generate and continuing with the pieces it can.
  • Support for Enums declared in "components/schemas" and references to them (#102).
  • Generated clients can now be installed via pip (#120).
  • Support for YAML OpenAPI documents (#111)

Internal Changes

  • Switched OpenAPI document parsing to use Pydantic based on a vendored version of openapi-schema-pydantic (#103).
  • Tests can now be run on Windows.

0.4.2 - 2020-06-13

Additions

  • Support for responses with no content (#63 & #66). Thanks @acgray!
  • Support for custom string formats (#64 & #65). Thanks @acgray!

0.4.1 - 2020-06-02

Additions

  • Support for Python 3.7 (#58)

0.4.0 - 2020-05-30

Breaking Changes

  • Classes generated to be included within lists will now be named like Item. For example, if a property named "statuses" is an array of enum values, previously the Enum class declared would be called "Statuses". Now it will be called "StatusesItem". If a "title" attribute was used in the OpenAPI document, that should still be respected and used instead of the generated name. You can restore previous names by adding "StatusesItem" to the class_overrides section of a config file.
  • Clients now require httpx ^0.13.0 (up from ^0.12.1). See httpx release notes for details.

Additions

  • Support for binary format strings (file payloads)
  • Support for multipart/form bodies
  • Support for any supported property within a list (array), including other lists.
  • Support for Union types ("anyOf" in OpenAPI document)
  • Support for more basic response types (integer, number, boolean)
  • Support for duplicate enums. Instead of erroring, enums with the same name (title) but differing values will have a number appended to the end. So if you have two conflicting enums named MyEnum, one of them will now be named MyEnum1. Note that the order in which these are processed and therefore named is entirely dependent on the order they are read from the OpenAPI document, so changes to the document could result in swapping the names of conflicting Enums.

Changes

  • The way most imports are handled was changed which should lead to fewer unused imports in generated files.

  • Better error messages

    • Most error messages will contain some useful information about why it failed instead of a stack trace
    • Client will still be generated if there are recoverable errors, excluding endpoints that had those errors

  • Output from isort and black when generating will now be suppressed

Fixes

  • Defaults within models dataclasses for Dict or List properties will now be properly declared as a field with the default_factory parameter to prevent errors related to mutable defaults.
