i have an idea: overwrite MultipleChoiceFilter: from django.forms.fields import MultipleChoiceField from django_filters.filters import MultipleChoiceFilter... class MultipleField(MultipleChoiceField): def valid_value(self, value): return True. class MultipleFilter(MultipleChoiceFilter): field_class = MultipleField. class xxxFilter(django.filters.FilterSet) The filtering in MultipleChoiceFilter is a potential noop. #20 and #44 brought this up as a painful performance hit. The logic introduced in response to #20 is not always sound. As per #132, the filter must be required for it to apply. As per #176 and #184, only a subset of choices may be specified. This pull request adds a always_filter flag and is_noop test to MultipleChoiceFilter MultipleChoiceFilter skips filtering if the number of choices of the filter are equal to the number of choices of the field. The reason behind this is probably that if all choices are allowed then filtering doesn't make any sense. That is correct of the field is required to have a value, but not if the field can be empty. In that case it will fail to filter out the records that don't have any. Similar to a MultipleChoiceFilter except it works with related models, used for ManyToManyField by default. NumberFilter ¶ Filters based on a numerical value, used with IntegerField, FloatField, and DecimalField by default. RangeFilter ¶ Filters where a value is between two numerical values. DateRangeFilter ¶ Filter similar to the admin changelist date one, it has a number of common.

This allows to use an annotated field easily, without overriding filter altogether: class MyMultipleChoiceFilter(django_filters.ModelMultipleChoiceFilter): def get_filter_predicate(self, v):. This replaces the unreleased get_filter_predicate with map_values, which results in less verbose SQL with annotated fields, where the CAST etc would be repeated for each value.
