23624	Regression in ManyToManyField with through, runtime-generated models	Ludovico Magnocavallo	nobody	"I admit my situation is a corner case: an app interfacing with a legacy db, where I need to extend an abstract model to contextualize it to identical tables, named differently (eg obj_1 table, obj_2 table, etc.), and to make things worse the number of tables is only known at runtime.

I am then dynamically generating a module for each set of models, and while things work great in Django 1.6, in 1.7 ManyToManyField using a through model breaks.

I am attaching a sample models.py file that illustrates the issue. I have not yet found the time to delve into what's happening, I hope someone with a better understanding of all the related stuff steps in as it's something I have never looked into.
