[bussiere adrien]

# -*- coding: utf-8 -*-
def ensurefirstuser(firstname,lastname,email,password)​:
    users = db(db.auth_user.email==email).​select()
    if users:
        user_id = users[0].id
        created = False
        if settings.debug_ensure_first_​user == True:
            print ('found user_id so created equals %s') % created
        return (user_id,created)

    else:
        my_crypt = CRYPT(key=auth.settings.hmac_​key)
        crypt_pass = my_crypt(password)[0]        
        id_user= db.auth_user.insert(
                              ​     first_name=firstname,
                              ​     last_name=lastname,
                              ​     email = email,
                              ​     password = crypt_pass
                              ​     )
        created = True
        if settings.debug_ensure_first_​user == True:
            print ('creating user_id')
        return (id_user,created)

investing on it fr hours ...
