Removing need for first and last name in auth

[HittingSmoke]

I'd like to use auth with only a username instead of first and last
name. I defined my own tables without a first and last name but it
still causes issues throughout the app.

For instance, when I try to use appadmin to add a user to a new auth
group I get an error (<type 'exceptions.KeyError'> 'first_name') if
there is no first and last name fields in the database. If I create
them but make them unreadable and unwritable the page will load but
all of the entries in the User ID dropdown say "None None (user ID
#)".

The auth Welcome bar is also fixed to the first name field and if not
used it will says Welcome, None.

This seems like quite a huge oversight for such a robust auth system.
Usernames are far more common for user management than first and last
names and many people just plain refuse to give their real names to
random web sites that require authentication.

Is there a modded version of auth perhaps that can be used as a
plugin? Excuse me if that sounds stupid, I'm just started out with
this and could very well just be going about this all wrong.

I suggest you simply make the fields hidden

db.auth_user.first_name.readable = db.auth_user.first_name.writable =
False
db.auth_user.last_name.readable = db.auth_user.last_name.writable =
False

The default validator for auth_permission.user_id and auth_event.user_id is:

IS_IN_DB(db, '%s.id' % settings.table_user_name,

    '%(first_name)s %(last_name)s (%(id)s)')

After calling auth.define_tables(), you can change those to:

db.auth_permission.user_id.requires = IS_IN_DB(db, '%s.id' %

    settings.table_user_name, '%(username)s (%(id)s)')

Perhaps this should happen automatically when the first_name and last_name fields are not included in auth_user.

The auth Welcome bar is also fixed to the first name field and if not
used it will says Welcome, None.

You can easily replace the navbar by removing auth.navbar from the layout.html view and replacing it with a custom navbar. However, we should make auth.navbar more customizable. Please open an issue (http://code.google.com/p/web2py/issues/list) and reference this thread.

Agree. I will take a patch

[HittingSmoke]

Thank you. The issue has been submitted with a link back to this
thread.

The issue says fixed, so am I to understand there's now a way to customize the auth.navbar Welcome message that hasn't been documented yet or was this simply a fix for the breakage issues?

I've added these lines, and now the fields are hidden both on the signup page and on the profile page.

How can I make the fields hidden only on the signup page? 

I want the user to be able to add their name later on the profile page.

i think you can use conditional if to check the url and then hide the fields

e.g.

if 'register' in request.args :

db.auth_user.first_name.readable = db.auth_user.first_name.writable = False

db.auth_user.last_name.readable = db.auth_user.last_name.writable = False

Thanks, stifan.

Now, the only problem is the first and last name fields on the profile page are required. Can I make them optional?

pls try

models/db.py

custom_auth_table = db[auth.settings.table_user_name] # get the custom_auth_table

custom_auth_table.first_name.notnull = False

custom_auth_table.last_name.notnull = False

custom_auth_table.first_name.required = False

custom_auth_table.last_name.requires = False

auth.settings.table_user = custom_auth_table
