Admin ignores to_field on ForeignKey

[vbs]

i am using django 1.2.1. when i use Foreignkey.to_field , the field in the add step of admin still shows "course object", not the char string i specify to. thus i don't know which course i am adding.

it seems like this ticket: ​http://code.djangoproject.com/ticket/8648, but i am using django 1.2.1

code:

# models.py
class course(models.Model):
    """
    course model
    """
    num_of_course = models.CharField(max_length = 32, unique = True)
    num_of_student = models.IntegerField()
    send_email_flag = models.IntegerField()
    timestamp = models.DateTimeField(auto_now_add=True)
    

class ticket(models.Model):
    """
    model for student who asks for the notifier
    """
    
    user = models.ForeignKey(User)
    email = models.CharField(max_length = 75)
    course = models.ForeignKey(course, to_field='num_of_course')
    email_num = models.IntegerField()
    stop_email_flag = models.IntegerField()
    timestamp = models.DateTimeField(auto_now_add=True)


#admin.py
class TicketModel(admin.ModelAdmin):
    list_display = ('user', 'email_num', 'course', 'email_num', 'stop_email_flag',
    'timestamp')
    
admin.site.register(models.ticket,TicketModel)

You must define a unicode method on course if you do not want the admin to show "<course object>". This has nothing to do with to_field on a ForeignKey.

but if i just want a specified field rather than an object, how can i do?

Thank you.
