Having trouble with a somewhat unconventional modelling in Rails
Take three table.
1. User model with primary integer id and a unique string guid.
2. Model X has foreign key to User as integer user_id and its model
3. Model Y has foreign key to User as string user_guid and its model
belongs_to :users, :foreign_key => 'user_guid'
This tells Rails which column to use in Model Y to look up Users.
But How do I tell Rails which column to use in User?
In other words, how do I tell Rails to join (or select) from
Users.guid instead of Users.id when referencing Y.user?
The has_one and has_many association has a :primary_key option, but
this seems to be missing on the belongs_to association
How do people work around this? Any help would be greatly
