There are over forty forks of this unmaintained project now so to summarise the goals of our fork:

• Allow further extensibility of the BaseEntityForm so that the attributes shown can be further filtered per-form-instance. The use-case is when there is data in the request that affects the values you show on your form that cannot be passed to the get_attributes method on an EavConfig object.
• Use a ModelChoiceField for the EnumValue drop down entries, to fix a bug where Must be an EnumValue model object instance validation errors were raised whenever a value was set on a drop-down.
• Fix up the setup.py configuration and add a MANIFEST.in to allow us to package the application.
• Fix bugs as we find them, ideally pulling in patches from other forks where possible.
• Fixes the slug validation where hyphens were previously valid

This is a fork of https://github.com/mvpdev/django-eav, to make it Python 3 compatible.

django-eav provides an Entity-Attribute-Value storage model for django apps.

For a decent explanation of what an Entity-Attribute-Value storage model is, check Wikipedia.

You can install django-eav directly from guthub:

pip install -e git+git://github.com/mvpdev/django-eav.git#egg=django-eav

Add eav to your INSTALLED_APPS in your project's settings.py file.

Before you can attach eav attributes to your model, you must register your model with eav:

>>> import eav
>>> eav.register(MyModel)

Generally you would do this in your models.py immediate after your model declarations.

>>> from eav.models import Attribute
>>> Attribute.objects.create(name='Weight', datatype=Attribute.TYPE_FLOAT)
>>> Attribute.objects.create(name='Color', datatype=Attribute.TYPE_TEXT)

>>> m = MyModel()
>>> m.eav.weight = 15.4
>>> m.eav.color = 'blue'
>>> m.save()
>>> m = MyModel.objects.get(pk=m.pk)
>>> m.eav.weight
15.4
>>> m.eav.color
blue

>>> p = MyModel.objects.create(eav__weight = 12, eav__color='red')

>>> MyModel.objects.filter(eav__weight=15.4)

>>> MyModel.objects.exclude(name='bob', eav__weight=15.4, eav__color='red')
