Django: Filter a Queryset made of unions not working

Question

I defined 3 models related with M2M relationsships

class Suite(models.Model):
    name = models.CharField(max_length=250)
    title = models.CharField(max_length         


        

Answer 1

I had the same issue and ended up using the union query as a subquery so that the filters could work:

yourModelUnionSubQuerySet = YourModelQS1.union(YourModelQS2)
yourModelUnionQuerySet = YourModel.objects.filter(id__in=yourModelUnionSubQuerySet.values('id'))
