TypeError at /datawizard/ about django-data-wizard HOT 2 CLOSED

Hey @mureiken ,
I had the same error using Django 1.11, Python 3.6, restframework 3.8.2, running on Ubuntu 18.04
This is how I solved it, it is an ugly / dirty fix, I know, but at least I was able to have my code running.
In data_wizard package open serializers.py and to go line 27, find following lines

def to_representation(self, content_type_id):
        ct = ContentType.objects.get(pk=content_type_id)
        return '%s.%s' % (ct.app_label, ct.model)

and replace those with code below

def to_representation(self, content_type_id):
        if type(content_type_id) is int:
            ct = ContentType.objects.get(pk=content_type_id)
        else:
            ct = ContentType.objects.get(pk=content_type_id.pk)
        return '%s.%s' % (ct.app_label, ct.model)

I kept the name of input argument the same name in case function is being called elsewhere using the argument names. I know it is a dirty fix, but at least my application is working, hope it helps you

I fixed the implementation of the ContentTypeIdField so the workaround should no longer be needed. Thanks for reporting!
