3.0.7: the model uses 'id' field even when 'set_primary_key :uid' set
Reported by Roland Pallai | May 15th, 2011 @ 01:37 AM
Rails console:
> Rails.version
=> "3.0.7"
> User.primary_key
=> "uid"
> User.last.uid
=> 54306
> User.last.attributes['id']
=> 54306
> User.last.id
=> 3
> User.last.to_key
=> [3]
> User.last.reload
ActiveRecord::RecordNotFound: Couldn't find User with ID=3
[...]
log/development.log:
User Load (0.7ms) SELECT `sql_users`.* FROM `sql_users` WHERE `sql_users`.`uid` = 3 LIMIT 1
As you can see, the User model has an 'id' field too, next to 'uid'. If I comment out the "set_primary_key :uid" on User, reload works as expected. This model works in 2.3.11.
Associations are also affected, not just the reload.
A simple workaround:
class User
alias_attribute(:id, :uid)
end
