Database error : no such column: connect_connect.reciever_id - database

Question

I have created following model
class ConnectToFrom(models.Model):
person = models.ForeignKey(User, null=True)
kiosk = models.ForeignKey(Kiosks, null=True)
class Connect(models.Model):
parent_id = models.ForeignKey("self", null = True, blank = True)
sender = models.ForeignKey(ConnectToFrom, related_name='sent_messages' )
reciever = models.ForeignKey(ConnectToFrom, related_name='received_messages')
.
.
.
I am not able to access Connects to add any connect object through admin site !
Can i not reference same model to two fields ?
I am not able to figure out what exactly is causing the error .
Please help

Answer 1

Did you add the receiver field to your model after you initially created the connect_connect table? If so you'll have to manually add that field to your database (Django does not automatically sync changes to your models with your database.)
Just launch your interactive db shell, usually dbshell, and add the field. In MySQL it would be something like:
ALTER TABLE connect_connect ADD COLUMN receiver_id integer;
I'd recommend running manage.py sqlall appname to see how Django would create your db tables now, and then make sure the db matches that by making the necessary changes through your db shell.
