-----------------------------------------+------------------------
`BaseModelAdmin.raw_id_fields` is a very feature in django admin that
prevents page timing out or crashing when a related field's table has too
many records for the default django admin dropdown widget. Alternatively,
`autocomplete_fields` has the same objective, but using a different
widget.
Currently, there exists a method hook
`BaseModelAdmin.get_autocomplete_fields(request)` which can be overridden
by child admin classes for customized logic. But there is no
`get_raw_id_fields` hook that allows us to add some logic for
`raw_id_fields`. It would be useful to have this hook also included in the
admin. Right now we are working around this by adding our custom logic to
populate the raw_id_fields in the `__init__` method instead.
We need this code to be added to the `BaseAdmin` class.
{{{
def get_raw_id_fields(self, request):
"""
Return a list of ForeignKey and/or ManyToMany fields which should use
a raw id widget.
"""
return self.raw_id_fields
}}}
--
The specific use case we have for this is we are writing a custom admin
class that automatically sets all of the related fields (FK, O2O, M2M) of
a model to `raw_id_fields` or `autocomplete_fields` so devs doesn't have
to manually configure the admin every time a new field is added / removed
to the model.
