Increase length of email field to accomodate Facebook proxied addresses

[Graham King]

The proxied email addresses Facebook provides via it's API look something like this: apps+107627842277.100000147873279.3fbf72360a409641ecb9202d8ac5af5e@…

That's 89 characters long, so it doesn't fit into the 75 characters in django.contrib.auth.models.User.email.

I'd like to suggest increasing that field's max_length to 200.

The only potential downside is that certain databases (Oracle) limit the total potential size of a row. That would only matter if someone heavily extended the auth_user table, which is rare. Usually the profile feature is used.

Can anyone see this causing a problem?

I would suggest doing this to all EmailField, so changing

django.db.models.field.__init__.py

line 641:

kwargs['max_length'] = kwargs.get('max_length', 75)

to replace the 75 with a 200. If this pushed a user table over the limit you can always pass max_length to EmailField.

The safer way is to add a max_length to auth.User's EmailField.
