    <p>I have an app in which users can follow law firms</p> <p>I have 3 models - User - Firm - Follow</p> <pre><code>class Firm &lt; ActiveRecord::Base has_many :follows, :dependent =&gt; :destroy has_many :users, :through =&gt; :follows class User &lt; ActiveRecord::Base has_many :follows, :dependent =&gt; :destroy has_many :firms, :through =&gt; :follows class Follow &lt; ActiveRecord::Base belongs_to :firm belongs_to :user </code></pre> <p>In a table in my firms index view, I would like to take the current signed and create an association between that user and the law firm - through the follow table.</p> <p>In effect doing this - firm.users &lt;&lt; User(current)</p> <p>This is the code that I have at present, how would you suggest that I structure the path, and the corresponding controller?</p> <pre><code>&lt;% @firms.each do |firm| %&gt; &lt;tr id = "firm_&lt;%= firm.id %&gt;"&gt; &lt;td&gt;&lt;%= link_to image_tag(firm.logo_url, :size =&gt; "80x120"), firm.url %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to firm.name, firm_path(firm) %&gt;&lt;/td&gt; &lt;% if user_signed_in? %&gt;&lt;td&gt; &lt;%= button_to 'Follow', ? , method: :post %&gt; &lt;/td&gt; &lt;% end %&gt; </code></pre> <p>I am using devise for the User authentication and have put the following helpers into application helper to allow my login partial to function in a different models view.</p> <pre><code> def resource_name :user end def resource_id :user_id end def resource @resource ||= User.new end </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.
