I'm installing a new app (social) on my django project.

When I enter `python manage.py runserver 0.0.0.0:8000` I get the following error

```
Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x971d56c>>
Traceback (most recent call last):
...
django.core.management.base.CommandError: One or more models did not validate:
social.socialall: "client_name": CharFields require a "max_length" 
attribute that is a positive integer.
social.socialall: "customer_name": CharFields require a "max_length" attribute that is a positive integer.
social.socialall: "publisher_id": CharFields require a "max_length" attribute that is a positive integer.
social.socialall: "currency": CharFields require a "max_length" attribute that is a positive integer.

```

I created a social model a while back but never used it so deleted it from the code.

I'm trying to figure out where does `social.socialall` this lives. I'm assuming django.db.models but I'm querying my SQL database and can't find anything.

I only get this error message when I include social in installed\_apps.
