How to use Q objects to test list membership?

Question

With normal Django querysets, if I want to retrieve all the myObjects whose "a" attribute is 1, 2 or 3, I would do the following:

myObjects.objects.filter(a_in=[1,2,3])

But I would like to do this using the Q objects. How would I write the equivalent query with Q objects?

Answer 1

It should look like this:

myObjects.objects.filter(Q(a = 1) | Q( a = 2) | Q( a = 3))

I don't know why you want to do that but you can also do

myObjects.objects.filter(Q(a__in=[1,2,3])
