Django - How to save m2m data via post_save signal?

Question

(Django 1.1) I have a Project model that keeps track of its members using a m2m field. It looks like this:

class Project(models.Model):
    members = models

I can't see anything wrong with your code, but I'm confused as to why you think the admin should work any different from any other app.

However, I must say I think your model structure is wrong. I think you need to get rid of all those ForeignKey fields, and just have a ManyToMany - but use a through table to keep track of the roles.

class Project(models.Model):
    members = models.ManyToManyField(User, through='ProjectRole')

class ProjectRole(models.Model):
    ROLES = (
       ('SR', 'Sales Rep'),
       ('SM', 'Sales Manager'),
       ('PM', 'Project Manager'),
    )
    project = models.ForeignKey(Project)
    user = models.ForeignKey(User)
    role = models.CharField(max_length=2, choices=ROLES)
