    <p>Sorry if I mess something up, but I'm new here, so bear with me.</p> <p>Here's kinda what I want to do. I want to dynamically assign ID tags to links based on the user ID's in my database. Then based on which link that I click, I want that link to call the controller helper and pass in its ID to the helper method.</p> <p>So far, I'm able to dynamically assign each link for each user, but my problem is when I click the link and it calls the controller method <strong>callThis</strong> with the ID, it gets the last user's (the last user in the database) ID instead of the user ID of the link that I clicked.</p> <p>My question is, how do I get it to send the ID of the link that I click, and not the ID of the last user in the database?</p> <p>Here's my code. <br/><br/> <strong>index.html.erb</strong></p> <pre><code>&lt;div id="profile"&gt;&lt;/div&gt; &lt;table&gt; &lt;% @users.each do |u| %&gt; &lt;% if !u.nil? and u.department_id == department.id %&gt; &lt;tr class="&lt;%= department.id %&gt;" style="display:none;text-align:left;"&gt; &lt;td&gt; &lt;a href="#id-&lt;%= u.id %&gt;" id="id-&lt;%= u.id %&gt;" onclick="&lt;%= callThis(u.id) %&gt;; refresh();"&gt; &lt;%= "#{u.first_name} #{u.last_name}" %&gt; &lt;/a&gt; &lt;/td&gt; &lt;/tr&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;/table&gt; &lt;script&gt; function refresh(){ $('#profile').html("&lt;%= escape_javascript(render(:partial =&gt; 'profile')) %&gt;"); } &lt;/script&gt; </code></pre> <p></p> <p><strong>professors_controller.rb</strong></p> <pre><code>class ProfessorsController &lt; ApplicationController helper_method :callThis helper_attr :get_id attr_accessor :get_id def index @departments = Department.all @users = User.with_role :Professor @search = @users.search(params[:q]) @result = @search.result @id = 0 end def callThis(id) @id = id end def get_id @id end end </code></pre> <p><strong>profile.html.erb</strong></p> <pre><code>&lt;%= get_id.to_s %&gt; </code></pre>

    1. COYou're doing it all wrong, `callThis(id)` instead of being called at click, is called once for every user in `@users` variable, on the server, not on client. What exactly do you want this link to do?

    2. CO@MarekLipka I want the link to call the callThis(id) function whenever it's clicked, and send the link's ID into the method so it can be shared by the profile.html.erb. I'm probably not doing it right, I'm a newbie at RoR.

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.
