    <p>Edit: Solution Worked Perfectly. <a href="http://api.rubyonrails.org/classes/ActionController/RecordIdentifier.html" rel="nofollow noreferrer">dom_id</a></p> <p>I am trying to pass data to a partial and use it to change roles of a user. Right now it will only change the roles of one user. When it is rendered it only displays and acts on the roles of <code>User.first</code></p> <p>Where it is rendered. i pass the user in locals. as per <a href="https://stackoverflow.com/questions/4700617/pass-a-variable-into-a-partial-rails-3">this post</a> I used the second answer because the first one didnt work and gave me errors. </p> <pre><code>&lt;%= render :partial =&gt; 'roles', :locals =&gt; { :user =&gt; user } %&gt; </code></pre> <p>Below is the partial _role.html.erb</p> <pre><code>&lt;div id="roleModal" class="reveal-modal"&gt; &lt;%= semantic_form_for user, :url =&gt; user_path(user), :html =&gt; {:method =&gt; :put } do |f| %&gt; &lt;h3&gt;Change Role&lt;/h3&gt; &lt;div class="reveal-modal-body"&gt; &lt;%= f.input :roles, :as =&gt; :check_boxes, :input_html =&gt; { :selected =&gt; user.role_ids } %&gt; &lt;/div&gt; &lt;a class="close-reveal-modal"&gt;&amp;#215;&lt;/a&gt; &lt;%= f.action :submit, :as =&gt; :button %&gt; &lt;% end %&gt; </code></pre> <p></p> <pre><code>&lt;% @users.each do |user| %&gt; &lt;tr&gt; &lt;td&gt;&lt;%= link_to user.name, user %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= user.email %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= user.created_at.to_date %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= user.roles.first.name.titleize unless user.roles.first.nil? %&gt;&lt;/td&gt; &lt;td&gt; &lt;a href="roles#&lt;%= user.id %&gt;" data-reveal-id="roleModal" class="button" type="button"&gt;Change role&lt;/a&gt; &lt;%= render :partial =&gt; 'roles', :locals =&gt; { :user =&gt; user } %&gt; &lt;/td&gt; &lt;/tr&gt; &lt;% end %&gt; </code></pre>

    2. COThis does not work although i feel like it should. It only displays and changes the role for the first user. It does not matter who is logged in as long as they are an admin. I am trying to figure out why?

    3. COIf you're passing User.first to the partial it's going to render the data for that first user in your database every time. Call the render partial line in a loop that calls it for each user you want that form to display for

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
