In db.py I have implemented it. Still when the Register form shows up there
is
a username present, note I added this: auth.define_tables(username=False)
db.define_table('auth_user',
Field('username', type='string',
label=T('Username')),
Field('first_name', type='string',
label=T('First Name')),
Field('last_name', type='string',
label=T('Last Name')),
Field('email', type='string',
label=T('Email')),
Field('password', type='password',
readable=False,
label=T('Password')),
Field('created_on','datetime',default=request.now,
label=T('Created On'),writable=False,readable=False),
Field('modified_on','datetime',default=request.now,
label=T('Modified On'),writable=False,readable=False,
update=request.now),
Field('registration_key',default='',
writable=False,readable=False),
Field('reset_password_key',default='',
writable=False,readable=False),
Field('registration_id',default='',
writable=False,readable=False),
format='%(username)s',
migrate=settings.migrate)
auth.define_tables(username=False)
db.auth_user.first_name.writable = db.auth_user.first_name.readable = False
db.auth_user.last_name.writable = db.auth_user.last_name.readable =False
