Fallback behavior for the callable filter about django-url-filter HOT 3 OPEN

not any simple way at the moment

from django-url-filter.

That's ok, it was as simple as adding the following:

    @form_field_for_filter(forms.CharField())
    def filter_exact_for_django(self, queryset, spec):
        value = json.loads(spec.value)
        f = queryset.filter if not spec.is_negated else queryset.exclude
        return f(status=value)

from django-url-filter.

In order to solve this problem, I wrote FallbackCallableFilter:

class FallbackCallableFilter(CallableFilter):
    def get_spec(self, config):
        spec = super(CallableFilter, self).get_spec(config)
        try:
            spec.filter_callable = self._get_filter_method_for_lookup(spec.lookup)
        except AttributeError:
            pass
        return spec

Perhaps this could be part of the project?

Note that @selimt's solution is not complete, as there are many other lookups besides __exact (__icontains, __in etc.).
