Django: union of different queryset on the same model

Question

I\'m programming a search on a model and I have a problem.

My model is almost like:

class Serials(models.Model):
    id = models.AutoField(primary_ke         


        

Answer 1

You can make those four queries and then chain them inside your program:

result = itertools.chain(qs1, qs2, qs3, qs4)

but this doesn't seem to nice because your have to make for queries.

You can also write your own sql using raw sql, for example:

Serials.objects.raw(sql_string)
