m2m tables greted twice

[anonymous]

This creates the m2m table twice.

This is idiomatic if you want the relation to show up bidirectionally in the admin or in autogenerated forms; cf. ​https://code.djangoproject.com/ticket/897

class Test1(models.Model):
    tests2 = models.ManyToManyField('Test2', blank=True)

class Test2(models.Model):
    tests1 = models.ManyToManyField(Test1, through=Test1.tests2.through, blank=True)

greted => created. *Sigh*.

Hmm, I guess this is the case, but it won't be a high priority to fix - after all, you'd be better off defining the through model explicitly as a separate model and assigning that to both M2Ms.
