Multiple many-to-many relations to the same model in Django

Question

Given the following model with two many-to-many relations:

class Child(models.Model):
    name = models.CharField(max_length=80)

class Foo(models.Model):
    ba         


        

Answer 1

You haven't read Django's documentation carefully enough. Here it says:

If you have more than one ManyToManyField pointing to the same model and want to suppress the backwards relations, set each related_name to a unique value ending with '+'.

The related_name attributes have to be unique, not the same.
