Django Tastypie用户注册

Question

I am creating an API using Django and TastyPie. I am trying to register a user via a resource. I took most of my code from this question that has a similar goal:

How to create or register User using django-tastypie API programmatically?

My problem is, I get a problem when registering a user.

The code is:

class RegisterUserResource(ModelResource):
    class Meta:
        allowed_methods = ['post']
        object_class = VouchersUser

        authentication = Authentication()
        authorization = Authorization()

        include_resource_uri = False
        fields = ['username']

        resource_name = 'register'

    def obj_create(self, bundle, request=None, **kwargs):
        try:
            bundle = super(RegisterUserResource).obj_create(bundle, request, **kwargs)
            bundle.obj.set_password(bundle.data.get('password'))
            bundle.obj.save()
        except IntegrityError:
            raise BadRequest('User with this username already exists')
        return bundle

When I send a POST (I do it programatically) with both username and password parameters, though, I get the following error back:

{"error_message": "The format indicated 'multipart/form-data' had no available deserialization method. Please check your formats and content_types on your Serializer.", "traceback": "Traceback (most recent call last):

UnsupportedFormat: The format indicated 'multipart/form-data' had no available deserialization method. Please check your formats and content_types on your Serializer.
"}

I can deduce there is some problem with the serializer but which and how can I solve it?

Thank you

Answer 1

I guess you are trying to use django.test.client.post with Tastypie. If so, you need to pass in an extra parameter - the content_type. Here is how your call should look:

client.post('/resource/to/create/', 'json_string_here', content_type='application/json')

Answer 2

had the same issue. passing "Content-Type: application/json" in header solved it for me.
