Comment:
We have the same problem '''even with a small number of fields'''.
Using some_queryset.only('somefield') results in new model/contenttype
creation with
diferred fields. We've used this qs method in some south migration. South
sends post_syncdb after model creations. Then django contrib.auth wants to
add
permission after receiving this signal and there is a problem with
Permission.name (i.e. 'Can add page_
deferred_layout_migrated_site_id_skin_template')
field size limited to max length=50 (or Permission.codename limited to
100)
This is maybe more a problem of South application (sending signals of
undeclared model
creations), but this is also a cause of '''uncontrolled size of generated
model name''' in deferred_class_factory()
