How to document function-based views parameters?

Question

I'm developing a REST API with Django 1.11 and Django REST Framework 3.7. I installed Django REST Swagger 2.1 to generate the documentation.

I'm using a function-based view like this:

from rest_framework.decorators import api_view, permission_classes

@api_view(['POST'])
@permission_classes((permissions.AllowAny,))
def jwt_auth(request, provider, format=None):
    """
    View description here
    """
    pass

As you can see, my view is recognized by Swagger and it has the correct description: "View description here".

However:

• You can see the "Description" column is empty for the provider URL parameter.
• The POST parameters are not documented (obviously, because there is no way for Swagger to know them)

How can I write documentation for the URL and POST parameters of a function-based view, as well as the responses?

I tried YAML Docstrings but it seems it's for the old version (0.3.x) and it doesn't work with version 2.x.

Answer 1

Following this github issue, it seems it's not possible for the method-based views as you stated.

But I think this link can help you.

Answer 2

You can use Schema of DjangoRestFrameWork. http://www.django-rest-framework.org/api-guide/schemas/

In your case, you can try the following.

---

from rest_framework.decorators import api_view, permission_classes, schema
from rest_framework import permissions

@api_view(['POST'])
@permission_classes((permissions.AllowAny,))
@schema(custom_schema)
def jwt_auth(request, provider, format=None):
    """
    View description here
    """
    pass

---

custom schema defintion

import coreapi, coreschema
from rest_framework.schemas import AutoSchema, ManualSchema

custom_schema = AutoSchema(manual_fields=[
    coreapi.Field("username", required=True, location="form", type="string", description="username here"),
    coreapi.Field("password", required=True, location="form", type="string", description="password field")
])

Should do the trick. For more detailed info, visit the link I provided at the top. Basic POST and GET parameters should work in this way.

Answer 3

use below code

@swagger_auto_schema(method='post', auto_schema=None)
@api_view(['POST'])
@permission_classes((permissions.AllowAny,))
def jwt_auth(request, provider, format=None):
    """
    View description here
    """
    pass
