A way to change default raw_id_fields behavior

[damon c]

Foreign key fields in the admin currently default to a behavior that can cause crashes and user inconvenience.

The default behavior is to render a <select> element containing every instance of the model referred to by the FK.

When this field refers to a model that has for example, 100,000 or more entries, this can have the affect of crashing a server, a browser, or at best making new users confused about why they cannot view the admin page for this instance.

A get_raw_id_fields method that enables

I don't think the justification is strong enough to warrant a backwards incompatible change here (i.e. every Django project would have to switch from opting-in to raw_id_fields to opting-out), but feel free to open a discussion on the DevelopersMailingList if you want to try to get a consensus otherwise.

You are totally right about this. I was just here to propose an alternate solution to this but I will start a discussion on the dev mailing list.

something like this...

def get_raw_id_fields(self):
        """
        Hook for overriding default raw_id_fields behavior
        """
        return self.raw_id_fields
