ValidationError in Snippets tutorial

[Xavier Ordoquy]

Validation is only intended from external data (basic Python types) to more complex structures (Django models). This happens during deserialization.
Here, you are already providing a complex model like it was basic Python types.

In order to work this around, it should be:

data = {
‘owner_id’: 1,
‘code’: ‘foo’
}
ser = SnippetSerializer(data=snippet, many=False)
ser.is_valid(raise_exception=True)

I checked out the Snippets tutorial and set it up working. Then I tried do a simple validation but I'm getting this error and I'm not sure why.
The serializer is the same from the tutorial: <https://github.com/encode/rest-framework-tutorial/blob/master/snippets/serializers.py>
from snippets.models import *
from snippets.serializers import *
snippet = Snippet()
snippet.owner_id = 1
snippet.code = "foo"
snippet.save()
ser = SnippetSerializer(data=snippet, many=False)
ser.is_valid(raise_exception=True)
