Reason for not allowing spaces in usernames?

[Wiiboy]

Why does Django not allow spaces in user's usernames? On my site, a
user's username is the first and last name combined (the equivalent of
user.get_full_name()).

[Joshua Partogi]

I guess it's just for simplicity and validation purposes. It would be really difficult to detect users with whitespaces I guess.

or a unix legacy - generally unix usernames do not allow spaces.

Do you think I would have problems if I disabled the checking for
spaces?

When I register users, I have it done automatically (user fills out a
form), and Django doesn't have a problem with a space there. It's
just in the Admin interface.

As long as you trim start and trailing spaces, there shouldn't be any
problem, but personally I wouldn't use spaces in usernames at all.

Why not?

Well, I can't really agree, but whatever, it shouldn't be hard to do..
just override the forms... at the worse of cases, the User model...

(imo) Allowing spaces in username just isn't a very sane approach.

Rather than telling the user to choose a username, why not make them login with their email address instead? Users are less likely to forget their email address, and if anything, it would be less error prone than a username would, especially one with spaces.

By all means, you can allow users to have spaces in their alias / nickname field, but allowing them to login with it might not be the best approach.

Hope this helps!

Generally a user, these days logs in with their email - that's predominately how I've setup all my django projects. People don't remember usernames. It is legacy, facebook connects with emails, so does gmail and the rest of the world. Username really has fallen back to a NickName / Alternative / Alias kind of field. You'd use it if you knew that in your application people wouldn't want their real, full names to be displayed.

Apparently some weirdness can be caused by having email addresses as usernames in django, though I'm not sure specifically what this is.

Does anyone know these cases?

If you need to do login via email address, it is possible right now -- it's just a little convoluted. You need to play around with custom authentication backends, and rewrite a bunch of forms.

In Django 1.5, we're addressing this by making the User model customisable. That means you can specify that the "username" is an EmailField, of whatever length you like, or you can specify the username is an "alias", which allows spaces -- whatever your use case requires. 

For more details, see the docs for the new feature [1]; 1.5 final should be released towards the end of this year.

One obvious problem case -- email addresses longer than 30 characters. The current username field has a 30 character max, which is easy to exceed if you try and put email addresses into the username field.

Django 1.5 addresses this by allowing your user model to be customisable, so you can make the username constraints whatever you want.
