Description (last modified by )
Up until Django 1.5.8 and Django 1.6.5 it was possible to have a ManyToMany field displayed in the admin on the "receiving-end" of the relationship with the ability to add new records.
Due to the restrictiveness of the new to_field_allowed method, one cannot open the popup for adding new records to the Model where the ManyToMany relationship is defined.
I realize this usage of the admin site is undocumented but, since the current code allows to perform that from the "receiving-end" of ForeignKey fields, IMHO it should also work for ManyToMany fields.
If the descriptions sounds too vague, see http://www.lasolution.be/blog/related-manytomanyfield-django-admin-site.html for a complete step-by-step explanation on how to reproduce.
