Search on FileField.name

Picking up where this conversation left off, would it be possible to add a filter for FileFields or maybe find a convenient workaround to add to the docs? I have tinkered with custom filters but nothing seems to work satisfyingly.

Hi @3ng7n33r

So the example from has #1478 this:

class QuestionnaireFilter(FilterSet):
    class Meta:
        model = Questionnaire
        fields = ['file']
        filter_overrides = {
            models.FileField: {
                'filter_class': CharFilter,
                'extra': lambda f: {'lookup_expr': 'exact'},
            },
        }

Would adding that to the filter_overrides doc solve your problem?

(The bottom line is I'm still not convinced filtering on FileField is particularly well defined, so would much rather folks define what they need for their own projects than add something not great to the package itself.)

Hey @carltongibson ,

Yes, that would totally work. I thought it was confusing that there was just no mention of FileFields in the filter docs even though they are Django native. This explanation + solution was exactly what I was looking for. If it is ok for you, I could draft a PR to update the docs to include this example.

That would be lovely. Thanks. (I'd extend the existing example. I don't know if you want some additional text, but happy to look at what you come up with.)

Kept it simple. Just enough so "FileField" and "FileFilter" will come up if someone searches for them.
