Unicode Type Error when adding M2M field

[Merric Mercer]

I have the following model:- class Rank_Advert(models.Model):     advert = models.ForeignKey(Advert)     brand = models.ForeignKey(Brand,verbose_name="brand_owner")     rank= models.IntegerField(default=1,blank=True)     def __unicode__(self):         return self.advert     class Admin:         save_on_top=True         list_display=('advert','brand','rank') Whenever, I try to save a new record to this model I am getting the following error:- Request Method: POST Request URL: http://localhost/admin/promotions/rank_advert/add/ Exception Type: TypeError Exception Value: coercing to Unicode: need string or buffer, Advert found Exception Location: C:\Python24\lib\site-packages\django\utils\encoding.py in force_unicode, line 37 Can anybody explain what's happening.  I've run out of ideas.
