Django Rest Framework: Disable field update after object is created

Question

I\'m trying to make my User model RESTful via Django Rest Framework API calls, so that I can create users as well as update their profiles.

However, as I go through

More universal way to "Disable field update after object is created" - adjust read_only_fields per View.action

1) add method to Serializer (better to use your own base cls)

def get_extra_kwargs(self):
    extra_kwargs = super(BasePerTeamSerializer, self).get_extra_kwargs()
    action = self.context['view'].action
    actions_readonly_fields = getattr(self.Meta, 'actions_readonly_fields', None)
    if actions_readonly_fields:
        for actions, fields in actions_readonly_fields.items():
            if action in actions:
                for field in fields:
                    if extra_kwargs.get(field):
                        extra_kwargs[field]['read_only'] = True
                    else:
                        extra_kwargs[field] = {'read_only': True}
    return extra_kwargs

2) Add to Meta of serializer dict named actions_readonly_fields

class Meta:
    model = YourModel
    fields = '__all__'
    actions_readonly_fields = {
        ('update', 'partial_update'): ('client', )
    }

In the example above client field will become read-only for actions: 'update', 'partial_update' (ie for PUT, PATCH methods)
