Multiple inheritance of newforms and modelforms

Multiple inheritance of newforms and modelforms

If you ever see “Error when calling the metaclass bases metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases” when trying multiple inheritance with newforms and modelforms, here’s a scary solution I found.

Quoting Google App Engine docs

2008-04-08T13:48:18+00:00

The Google App Engine model class, db.Model, is not the same as the model class used by Django. As a result, you cannot directly use the Django forms framework with Google App Engine. However, Google App Engine includes a module, db.djangoforms, which casts between the datastore models used with Google App Engine and the Django models specification. In most cases, you can use db.djangoforms.ModelForm in the same manner as the Django framework.

Better Use of Newforms

Better Use of Newforms

Two really neat techniques: using an inclusion tag template to DRY your custom form templates, and adding what-to-do-next methods to the form class itself to cut down on the application code in your views.

Using django.newforms with Pylons

Using django.newforms with Pylons

It’s always good to see Django components used outside of the framework itself. For the record, you can avoid the DJANGO_SETTINGS_MODULE environment variable entirely using django.conf.settings.configure (search for it).
