When using a proxy model:
class Uf(models.Model):
...
class CustomUf(Uf):
class Meta:
proxy = True
class CustomUfAdmin(admin.ModelAdmin)
admin.site.register(CustomUf, CustomUfAdmin)
It seems like only superusers can access the CustomUf through admin site... I can't figure out how to grant permissions on CustomUf to regular users...
Ok, Chris remark about content types gave me the hint...
I made the mistake to define the proxy object in "admin.py". This way, you have to be superadmin to access it.
If I define the proxy object in models.py, then the content type appears and everything works fine...
