Django 1.5 Custom User Model unknown column -

i using django 1.5s custom user model. want let user type username in - , logged in. no password (for testing anyway). user model doesnt have password. when try login admin following error:

operationalerror(1054, "unknown column 'hrms.password' in 'field list'" 

it seems trying execute query in authenticate() method.

select `myusers`.`password`, `myusers`.`last_login`, `myusers`.`id`, `myusers`.`user`, `myusers`.`name`, `myusers`.`firstname`, `myusers`.`lastname`, `myusers`.`organisation`, `myusers`.`unit`, `myusers`.`grade`, `myusers`.`email`, `myusers`.`position`, `myusers`.`manager` `myusers` `myusers`.`user` = 'warrenm' " 

i not have fields password, last_login - dont know why trying them.

below code.

my backend (auth.py)

from epmds.application.models import authuser  class mybackend(object):      def get_user(self, user_id):         # user user_id         try:             return authuser.objects.get(pk=user_id)         except authuser.doesnotexist:             return none      def authenticate(self, username=none, password=none):         # check username/password , return user         user = authuser.objects.get(user=username)         return user 

my model

class authuser(abstractbaseuser):     id = models.charfield(primary_key=true, max_length=15)     user = models.charfield('username', max_length=20, unique=true)     name = models.charfield(max_length=100)     firstname = models.charfield(max_length=100)     lastname = models.charfield(max_length=100)     organisation = models.charfield(max_length=100)     email = models.charfield(max_length=50, blank=true, null=true)      username_field = 'user'      def get_full_name(self):         full_name = '%s %s' % (self.first_name, self.last_name)         return full_name.strip()      def get_short_name(self):         return self.first_name      class meta:         ordering = ('lastname', 'firstname')         managed = false         db_table = 'myusers' 

password part of abstractbaseuser should added in authuser model in table.

as have managed=false model, need add explicitly.
