    267267Rename your application directory using a non-reserved name, i.e., "email_app" instead of "email". Go into the {{{INSTALLED_APPS}}} section of settings.py and change the name there too. Also, don't forget to do a syncdb to create the newly renamed app in your database. You may also want to go in to your database and drop the old "mis-named" table.

     269== unbound method contributee_to_class() == 
     270 
     271==== Symptom ==== 
     272 
     273A model does not validate with the following message: 
     274 
     275{{{ 
     276Validating models... 
     277project.allication: Error when calling the metaclass bases 
     278    unbound method contribute_to_class() must be called with TextField instance as first argument (got ModelBase instance instead) 
     2791 error found. 
     280}}} 
     281 
     282==== Possible Cause ==== 
     283 
     284A model field was not declared properly, the parentheses after the field types name were missing: 
     285 
     286wrong: 
     287{{{ 
     288#!python 
     289class Content(models.Model): 
     290    content = models.TextField 
     291}}} 
     292 
     293correct: 
     294{{{ 
     295#!python 
     296class Content(models.Model): 
     297    content = models.TextField() 
     298}}} 
     299 
     300==== Solution ==== 
     301 
     302The field declaration are sonething like generator methods, so they need parentheses after their name. Add them and the model will validate.
