Logical or of Django many to many queries returns duplicate results

Question

I have models with many to many relationships like this:

class Contact(models.Model):
    name = models.TextField()
    address = models.TextField()

class M         


        

Answer 1

As SQL returns all matching records, Django dutifully maps them to objects. What you're looking for is the .distinct() queryset method that makes SQL collapse all duplicate rows into one.
