python - Django: How to display foreign key value in admin form -

how admin form display foreign key value in drop down list of django admin form rather display 'table name object'? struggling work out.

here examples of model code (both contain catname field. catname pk in parent , fk in child).

parent(models.model): catname = models.charfield(db_column='catname', primary_key=true, max_length=255, verbose_name="catname")   description = models.charfield(db_column='description', max_length=255, blank=true, null=true)  class meta:     managed = false     db_table = 'parent'     verbose_name_plural = ('parent')      #def __unicode__(self): return self.catname.catname     def __str__(self):         return '%s' % (self.catname)    class child(models.model):     description = models.charfield(db_column='vardescription', max_length=255, blank=true, null=true)       cname = models.charfield(db_column='varname', primary_key=true, max_length=255)      catname = models.foreignkey(parent, db_column='catname', blank=true, null=true)      def __unicode__(self):         return self.name     def child_cat(self):         return self.catname.catname     class meta:         managed = false         db_table = 'child'         verbose_name_plural = ('child') 

admin looks like:

from django.contrib import admin  library.models import parent, child # register models here.  class childadmin(admin.modeladmin):     list_display = ('cname','description','child_cat')     fields=('cname','description','child_cat')     search_fields = ('cname','description')     ordering = ('cname',)  admin.site.register(child,childadmin) 

you can override form used modeladmin or change 1 field modeladmin.formfield_overrides.
