Hi,

I have a problem when I try do find a group in a plugin.

I changed the users table by adding "external_id" column (integer) because I need to save the external ID of the group but when I try to find the group, an insert is performed.
My code is :

group = Group.first(:conditions => "external_id = #{team['id']}")

The SQL:

Creating scope :sorted. Overwriting existing method Group.sorted.
  Group Load (0.2ms)  SELECT `users`.* FROM `users` WHERE `users`.`type` IN ('Group') AND (external_id = 1) LIMIT 1
   (0.2ms)  BEGIN
   (0.6ms)  INSERT INTO `groups_users` (`group_id`, `user_id`) VALUES (223, 224)
Mysql2::Error: Duplicate entry '223-224' for key 'groups_users_ids': INSERT INTO `groups_users` (`group_id`, `user_id`) VALUES (223, 224)
   (0.2ms)  ROLLBACK
Completed 500  in 1372ms

I do not understand why an insert is performed

Please help !!!

Sorry for my english !
