I'm trying to figure out the best way to add an email address form field to the edit page for a model in the Django admin, and, upon save, automatically set a hidden foreign key to associate said model instance to the Django user with this email address, or, alternatively, create a new user with said email address if one doesn't already exist.
Things I've thought of: * Add an actual database field for the email address, in addition to the ForeignKey that's already there, and add some glue in the save() method to set the second based on the first. This seems to be the easiest to implement, but I don't like the unnecessary duplication of data, and I'd also like the foreign key relationship to be maintained once it's set, even if the email address of the User changes, and it seems like there's risk of breakage in that event, with this approach. * Use a custom form for the model in the admin that tacks on an extra field, and, again, do some voodoo in save. * Make the foreign key field visible, but write a custom widget for it that looks like a regular text box, but looks to Django like a foreign key field. Would any of these work well? If so, which would be best? Am I missing anything? With which might it be easiest to reuse the same logic in a piston-powered API that exhibits the same behavior? Relatedly, in my application, it will be possible, but rare (and likely unintentional) for more than one instance of this model to be associated with the same User instance. In the event that I get this kind of likely-incorrect submission, is there a way to force a confirmation screen with a warning on it for a save in the admin, but let the user proceed if they really want to?
