Django permissions allows for 'view_modelname'. When users have view_modelname permission, these permission classes don't recognize it and reject access to the user.
My specific case was assigning customers to a group with the group having specific permissions allowed from the model permissions. Made this edit in an extension of DjangoModelPermissions to make it work. Thought it would be useful to have inherently.
Thanks to Jon Dufresne (@jdufresne) for review.

In some cases we end with an operation between two `OperandHolder`.
This didn't work as it didn't knew how to deal with | or &
This fixes by adding those operations.
`x and y` actually returns object y when both are true. the means P & IsAuthenticated will fail with TypeError: unsupported operand type(s) for &: 'instance' and 'bool' as IsAuthenticated now returns a CallableBool which does not overload __ror__
* permissions: Allow permissions to be composed
Implement a system to compose permissions with and / or.
This is performed by returning an `OperationHolder` instance that keeps the
permission classes and type of composition (and / or).
When called it will return a AND/OR instance that will then delegate the
permission check to the operands.
* permissions: Add documentation about composed permissions
* Fix documentation typo in permissions
* Identify code that needs to be pulled out of/removed from compat.py
* Extract modern code from get_names_and_managers in compat.py and remove compat code
* Extract modern code from is_authenticated() in compat.py and remove.
* Extract modern code from is_anonymous() in compat.py and remove
* Extract modern code from get_related_model() from compat.py and remove
* Extract modern code from value_from_object() in compat.py and remove
* Update postgres compat
JSONField now always available.
* Remove DecimalValidator compat
* Remove get_remote_field compat
* Remove template_render compat
Plus isort.
* Remove set_many compat
* Remove include compat
Quietly catching `AttributeError` and `TypeError` when calling
`get_queryset()` is rather insidious, as those exceptions get caught no
matter where they might happen in the call stack.
