Mustache template variables in the model

To obtain a list of variables (tags) available in the mustache template. Please use debugOperations and debugModels. Heres is an example for variables in the model templates:

java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate \
  -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml \
  -g csharp --global-property debugModels=true 

and here is part of the output:

############ Model info ############
[ {
  "model" : {
    "name" : "Order",
    "classname" : "Order",
    "classVarName" : "Order",
    "modelJson" : "{\n  \"type\" : \"object\",\n  \"properties\" : {\n    \"id\" : {\n      \"type\" : \"integer\",\n      \"format\" : \"int64\"\n    },\n    \"petId\" : {\n      \"type\" : \"integer\",\n      \"format\" : \"int64\"\n    },\n    \"quantity\" : {\n      \"type\" : \"integer\",\n      \"format\" : \"int32\"\n    },\n    \"shipDate\" : {\n      \"type\" : \"string\",\n      \"format\" : \"date-time\"\n    },\n    \"status\" : {\n      \"type\" : \"string\",\n      \"description\" : \"Order Status\",\n      \"enum\" : [ \"placed\", \"approved\", \"delivered\" ]\n    },\n    \"complete\" : {\n      \"type\" : \"boolean\",\n      \"default\" : false\n    }\n  },\n  \"xml\" : {\n    \"name\" : \"Order\"\n  }\n}",
    "vars" : [ {
      "baseName" : "id",
      "getter" : "getId",

      "datatypeWithEnum" : "long?",
      "name" : "Id",
      "defaultValue" : "null",
      "baseType" : "long?",
      "jsonSchema" : "{\n  \"type\" : \"integer\",\n  \"format\" : \"int64\"\n}",
      "hasMore" : true,
      "isPrimitiveType" : true,
      "isNotContainer" : true,
      "isEnum" : false
    }, {

Mustache template variables in the operation

For operation (resource) templates, please use debugOperations instead:

java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate \
  -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml \
  -g csharp --global-property debugOperations=true

Usage

For usage of the template variable, enter the variable name (e.g. basePath) in the search box and submit. Then filter by HTML & Django under Languages, e.g. https://github.com/openapitools/openapi-generator/search?l=html%2Bdjango&q=basepath&utf8=%E2%9C%93

Tips

To access the first or last element in a list

{{#vars}}{{#-first}} this is the first element {{.}} {{/-first}}{{/vars}}
{{#vars}}{{#-last}} this is the last element {{.}} {{/-last}}{{/vars}}

Explanations

Here are the explanations for some of the mustache tags:

• complexType: stores the name of the model (e.g. Pet)
• isContainer: true if the parameter or property is an array or a map.
• isPrimitiveType: true if the parameter or property type is a primitive type (e.g. string, integer, etc) as defined in the spec.

Please feel free to update the list above with more tags. For any question, please open an issue.
