How to tell flask-admin to use alternative representation when displaying Foreign Key Fields?

Question

How can I tell flask-admin to use an alternative representation for Foreign Key Fields such as the following in this RoleUser link table?

Answer 1

The simplest way is to add __str__ methods (__unicode__ for Python 2) to your models.

class Role(db.Model):
    # snip
    def __str__(self):
        return self.name
