## rails_admin belongs_to issue.md

               rails_admin belongs_to issue.md
            
          
    My app has, among others, an Article model and a User model. The Article model includes the line
belongs_to :author, class_name: 'User'

This would allow me to, for example, get the author's name via anArticle.author.name. The relevant ActiveRecord documentation indicates that :class_name is used to "[s]pecify the class name of the association", and gives a directly relevant example.
By contrast, the :foreign_key option for belongs_to specifies "the foreign key used for the association", but does not affect the name of the association. So, if I had
belongs_to :user, foreign_key: 'author_id'

the author's name of anArticle would be at anArticle.user.name. Not the same at all, and an invitation to disaster if I wish to add other User model references to an article (e.g., approved_by).
When I have my original, correct belongs_to declaration, anything in rails_admin that accesses my Article model throws an ActiveRecord::StatementInvalid exception in RailsAdmin::MainController#show, as shown in the attached exception report. rails_admin is simply ignoring the class_name specifier for the association.
I've read and reread the README and the wiki and have not seen any relevant information on the use of belongs_to with :class_name. This really is a showstopper for us; any help is greatly appreciated.
