I know that this is an older thread, but this was the first result that came up on google and I thought a better answer was necessary.

Via this django bug report I found the best way to have your ManyToManyField show up on both models:

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