How to display an attribute of a foreign key in the Django admin page

Question

I want to display the level field of the category to which the product is related on the object\'s admin page.

    class Category(m         


        

Answer 1

The simplest way is to put the level of the Category into the __unicode__ method:

class Category(models.Model):
    name = models.CharField(max_length=50, default=False)
    level = models.IntegerField(help_text="1, 2 ,3 or 4")

    def __unicode__(self):
        return u'%s [%d]' % (self.name, self.level)

So the select box will show it.
