Default object defined as dict, not object

[mtovt]

OAS says (section 4.7.25.1 of the spec):

... Unlike JSON Schema, the value MUST conform to the defined type for the Schema Object defined at the same level. For example, if type is string, then default can be "foo" but cannot be 1.

Example OAS:

openapi: 3.0.3
info:
  title: Example
  version: 0.1.0
servers:
- url: http://example.com
paths:
  /foo:
    delete:
      responses:
        '200':
          description: OK
components:
  schemas:
    Foo:
      type: object
      properties:
        text:
          type: string
          default: 987
        number:
          type: number
    Bar:
      type: object
      properties:
        foo:
          allOf:
          - $ref: '#/components/schemas/Foo'
          default:
            text: abc
            number: 123

Specification above generating following models

class Foo(BaseModel):
    text: Optional[str] = 987
    number: Optional[float] = None


class Bar(BaseModel):
    foo: Optional[Foo] = {'text': 'abc', 'number': 123}

I expected something like:

class Foo(BaseModel):
    text: Optional[str] = 987
    number: Optional[float] = None


class Bar(BaseModel):
    foo: Optional[Foo] = Foo(text='abc', number=123)

Why are default values used in a dict for now? Seems default values from this example should be generated as an instance of class Foo.

@mtovt I'm sorry for my too-late reply.
OK, I will support the feature.
Thank you!!

I just created the issue.
#1024

[koxudaxi]

I have released a new version 0.17.0
The version supports object and list default.

Examples

class Foo(BaseModel):
    text: Optional[str] = 987
    number: Optional[float] = None


class Bar(BaseModel):
    foo: Optional[Foo] = Field(
        default_factory=lambda: Foo.parse_obj({'text': 'abc', 'number': 123})
    )
    baz: Optional[List[Foo]] = Field(
        default_factory=lambda: [
            Foo.parse_obj(v)
            for v in [{'text': 'abc', 'number': 123}, {'text': 'efg', 'number': 456}]
        ]
    )
