    <p>Having this code in a view partial of type .js.coffee (it's being rendered as a view, not as an asset) :</p> <pre><code>&lt;% if @followed_car_ids.present? %&gt; for car_id_and_path in &lt;%= @followed_car_ids_and_paths.to_json %&gt; toggle_follow(car_id_and_path[0], true, car_id_and_path[1]) &lt;% end %&gt; </code></pre> <p>In the controller:</p> <pre><code>@followed_car_ids_and_paths = @followed_cars.map{|car| [car.id, url_for(current_user.car_subscriptions.find_by_car_id(car))]} </code></pre> <p>Note that it doesn't matter if I put the map (or collect) in the view. Doesn't work either if I put a simple string instead of <code>url_for(...</code>.</p> <p>It gives this error:</p> <pre><code>ActionView::Template::Error (Error: Parse error on line 1: Unexpected 'LOGIC'): 1: &lt;% if @followed_car_ids.present? %&gt; 2: for car_id_and_path in &lt;%= @followed_car_ids_and_paths.to_json %&gt; 3: toggle_follow(car_id_and_path[0], true, car_id_and_path[1]) 4: &lt;% end %&gt; app/views/general_ajax/_update_followed_cars.js.coffee:1:in `_app_views_general_ajax__update_followed_cars_js_coffee__3478461849674996439_70355260673980' </code></pre> <p>When I remove the <code>=</code> from <code>&lt;%=</code> on line 2 and add some kind of dummy array before the error stops:</p> <pre><code>for car_id_and_path in [1,2,3] &lt;% @followed_car_ids_and_paths.to_json %&gt; </code></pre> <p>The error doesn't occur if I use a flat array (not doubled with map):</p> <pre><code>for car_id_and_path in &lt;%= @followed_car_ids %&gt; </code></pre> <p>Neither when it's like this:</p> <pre><code>for car_id_and_path in [[1, 'a'],[2, 'b'],[3, 'c']] </code></pre>

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.
