    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.

     270
     271==== Symptom ====
     272
     273A model does not validate with the following message:
     274
     275{{{

     277project.allication: Error when calling the metaclass bases

     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.
