    <p>I'm trying to get Events from the User where EventView.promoter_id = User.id but it's not working properly. Here is my setup (currently incorrect):</p> <pre><code>User has_many :events has_many :promoted_event_views, :foreign_key =&gt; :promoter_id, :class_name =&gt; "EventView" has_many :promoted_events, :through =&gt; :event_views, :foreign_key =&gt; :promoter_id #foreign key seems to be getting ignored EventView belongs_to :event belongs_to :promoted_event, :class_name =&gt; "Event", :foreign_key =&gt; :event_id belongs_to :promoter, :foreign_key =&gt; :promoter_id, :class_name =&gt; "User" </code></pre> <p>The database is set up as:</p> <pre><code>User id ..etc (irrelevant) Event id user_id ...etc (irrelevant) EventView id user_id event_id promoter_id ...etc (irrelevant) </code></pre> <p>I'm trying to call:</p> <pre><code>User.all.first.promoted_events </code></pre> <p>It works, but it gives me the wrong information! It's not relating to the promoter_id on EventViews (what I want), but instead it's using user_id on Events </p> <p>Here's what's happening in the database:</p> <pre><code>User Load (0.2ms) SELECT `users`.* FROM `users` ORDER BY `users`.`id` ASC LIMIT 1 Event Load (2.1ms) SELECT `events`.* FROM `events` INNER JOIN `event_views` ON `events`.`id` = `event_views`.`event_id` INNER JOIN `events` `events_promoted_events_join` ON `event_views`.`event_id` = `events_promoted_events_join`.`id` WHERE `events_promoted_events_join`.`user_id` = 1 </code></pre> <p>It's pretty clear that the .<code>user_id</code> = 1 is causing the problem, how can I change this to promoter_id = 1? I've already tried setting primary_key and foreign_key on in the user model but it seems to be getting ignored.</p> <p>ALSO: I tried using finder_sql but it's deprecated in Rails 4</p>

    1. COI see `belongs_to :promoted_event, ... :foreign_key => :event_id` but I don't see an `event_id` column anywhere. Are you sure this is what you intended?

    3. COI don't know if it's related to the problem, but in your `EventView`, you're specifying the same foreign key for both `:event` (implicitly `event_id`) and `:promoter_event` (explicitly `event_id`).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
