custom table_name for table users with devise

Hi

for my app, I have several tables for users (franceusers, belgiumusers, …) and I would like to use one or another depending on domain

I tried with table_name_prefix and table_name but it seems to not work

class User < ActiveRecord::Base

rolify

Include default devise modules. Others available are:

:token_authenticatable, :confirmable,

:lockable, :timeoutable and :omniauthable

devise :database_authenticatable, :registerable, #:confirmable,

:recoverable, :rememberable, :trackable, :validatable

def self.table_name

debugger

‘franceusers’

end

def self.table_name_prefix

debugger

‘france’
end

thanks to debugger, I can see that is called but not self.table_name_prefix. And even if self.table_name if called, devise search users in tables users instead of franceusers

in console

User.table_name => “franceusers”

User.table_name_prefix => “france”

more weird, im also using activeadmin, and when I browse users list, I have an error :

Mysql2::Error: Unknown column '[franceusers.id](http://franceusers.id/)' in 'order clause': SELECT `users`.* FROM `users` ORDER BY `franceusers`.`id` desc LIMIT 30 OFFSET 0

it seems it can find table_prefix for field but not for FROM.

do I do anything bad ? is there another way to change users table name ?

thanks

merci
