I am getting the following error when the queryset tries to generate the SQL: "'str' object has no attribute 'ewkb'"
Here is what I am doing that causes the problem: shapes = Shape.objects.filter(geom__bboverlaps=bbx) shape_info = shape_info.filter(shape__in=shapes) Models are: class Shape(models.Model): … geom = models.PolygonField() color = models.IntegerField() class ShapeInfo(models.Model): … name = models.CharField(max_length=25) shape = models.ForeignKey(Shape) The code causing the problem seems to be: if (len(params) == 1 and params[0] == '' and lookup_type == 'exact' and connection.features.interprets_empty_strings_as_nulls): lookup_type = 'isnull' value_annot = True Is this not an appropriate way to use this?
