Custom Model.save() don't change relational data when editing via admin (probably any other forms too)

[anonymous]

Consider following models:

class A(models.Model):
    name = models.CharField(max_length = 100)

class B(models.Model):
    name = models.CharField(max_length = 100)
    related = models.ForeignKey(to = A, null = True, blank = True)

    def save(self):
        if not self.name.startswith('@'):
            self.name = '@' + self.name # this will work always
        if self.related and self.related.name.startswith('@'):
            self.related = None # won't work when editing via admin form
        super(B, self).save()

This illustrates that submitting the data via admin interface will always override relational changes in the custom Model.save() method. Other fields, however, are changed as expected.

Calling save() under some other circumstances will always change relational data as expected.

Any glue how to fix it? Thanks.

I could not reproduce this behavior. Can anybody else?

I'm not able to duplicate this either. Please reopen with more details if this is still happening.
