16756	Edit item with non integer value and inheritance fails on id.	ck2329@…	nobody	"Start new project, create 3 models:


{{{
class Tr1(models.Model):
    en    = models.CharField(max_length=100)
    def __unicode__(self):
        return ""%s""%(self.en)
    class Meta:
        ordering = ['en']
        
class Location2(models.Model):
    lon       = models.DecimalField(max_digits=9,decimal_places=6, blank=False)
    tr        = models.ForeignKey(Tr1,  unique=True) 
    
class Airport3(Location2):
    IATA    = models.CharField(primary_key=True, max_length=3, )
    def __unicode__(self):
        return ""%s""%(self.pk)
}}}
    

Set default admin interfaces:


{{{
admin.site.register(Tr1)
admin.site.register(Location2)
admin.site.register(Airport3)
}}}


Now login into admin site, create Airport3 instance, save it. Open it again, modify anything, try to save. Exception will be raised: '''invalid literal for int() with base 10: 'ABC'''''''', where ABC is IATA field value.

Now remove tr field from Location2 model - repeat create&edit - everything works well.
