django-rest-framework: Cannot call `.is_valid()` as no `data=` keyword argument was passed when instantiating the serializer instance

Question

I\'ve the following model:

class NoteCategory(models.Model):
    title = models.CharField(max_length=100, unique=True)

    def __unicode__(self):
        re         


        

Answer 1

When you want to serialize objects, you pass object as a first argument.

serializer = CommentSerializer(comment)
serializer.data
# {'email': u'leila@example.com', 'content': u'foo bar', 'created': datetime.datetime(2012, 8, 22, 16, 20, 9, 822774)}

But when you want to deserialize you pass the data with a data kwarg.

serializer = CommentSerializer(data=data)
serializer.is_valid()
# True
serializer.validated_data
# {'content': 'foo bar', 'email': 'leila@example.com', 'created': datetime.datetime(2012, 08, 22, 16, 20, 09, 822243)}

So in your case you want to deserialize your post data, therefor you have to do:

serializer = PatientNoteSerializer(data=request.data)
