Stuck with nested serializer using Django Rest Framework and default user

Question:

Tag: django,api,rest,django-rest-framework,serializer

The models and serializers are described in the pastebin:

http://pastebin.com/ZxzxWY7V

In my database I have a user which also has a member profile and a set of credentials attached to it.

Now... when I run this as is and try to pull a user using the AuthUserModelSerializer I get the member and the credentials, but the MemberProfile is not passed! I can't figure out why. I'm not sure if it's because the MemberProfile is a 1 to 1 relationship (Tried changing it to Foreign key to test), or if there is something wrong with my model / serializer. Below is an example response from the API:

HTTP 200 OK
Vary: Accept
Allow: GET, PUT, PATCH, DELETE, HEAD, OPTIONS
Content-Type: application/json

{
    "id": 1,
    "username": "eric",
    "password": "pbkdf2_sha256$20000$xA5jPJVAByjo$i/FpmosJgsppVH4o5ctryDppOyG1ZaB+tQ2VIa+jFX0=",
    "email": "",
    "first_name": "",
    "last_name": "",
    "is_staff": true,
    "is_active": true,
    "date_joined": "2015-06-17T00:10:24.514894Z",
    "credentials": [
        {
            "credential_type": "O",
            "credential_number": "23423423",
            "date_received": "2015-06-17T00:27:49.367446Z",
            "is_verified": true,
            "date_verified": "2015-06-17T00:27:46Z",
            "document_image": "http://127.0.0.1:8000/api/v1/members/images/credentials/e990868659524470aadb9996c68384ba.ext/logo11w.png"
        }
    ]
}

EDIT: Fix was to change

class AuthUserModelSerializer(serializers.ModelSerializer):
    credentials = CredentialSerializer(many=True)
    member = MemberProfileSerializer(read_only=True)

to

class AuthUserModelSerializer(serializers.ModelSerializer):
    credentials = CredentialSerializer(many=True)
    member = MemberProfileSerializer(read_only=True, source='profile')

Thank you Linovia


Answer:

By default DRF will look at an attribute on the User model named after the serializer's field (member here). However the related name is profile.

This can be worked around by passing the source="profile" to your MemberProfileSerializer.
