hack to fix an issue where declaring an AllLookupsFilter as < my_field = AllLookupsFilter(name='m__f') > works with query param 'my_field' only for exact, 'my_field__contains' param does not work, however 'm__f__contains' does. requires declaring the filter as < my_field = AllLookupsFilter(name='m__f', alias='my_field') >. A better solution would be to derive the name from the attribute and not from the label.
