    <p>I am trying to finish my forum application. I want arrange user Friendships. I am using devise as authentication system. I want some suggestions. Shall i nest the resources in User and Friendships. This is the way Railscasts used:</p> <pre><code>devise_for :users resources :users, only: [:index, :show] resources :friendships, only: [:create, :destroy] </code></pre> <p>This is how i used: </p> <pre><code>devise_for :users resources :users, only: [:index, :show] do resources :friendships, only: [:create, :destroy] end </code></pre> <p>My real problem is that . I want to use friendships in a way that , signed_in user can check the users list , and add a friend if he is not in the friendslist. Now i can add a friend multiple times. And also ,user can add himself as a friend.</p> <p>How can i fix this links with <code>if/else</code> statements:</p> <p>showing a user profile works:</p> <pre><code>&lt;section&gt; &lt;h1&gt; &lt;%= @user.username %&gt; &lt;/h1&gt; &lt;%= link_to "Arkadaşlarıma Ekle", friendships_path(:friend_id =&gt; @user), :method =&gt; :post,class: "btn btn-large btn-primary" %&gt; &lt;/section&gt; </code></pre> <p>and herei I cant find the way to show the friend's profile. :</p> <pre><code>&lt;% for friendship in @friendships %&gt; &lt;%= link_to friendship.friend.username, '#' %&gt; (&lt;%= link_to 'Sil', friendship, :method =&gt; :delete %&gt;) &lt;% end %&gt; </code></pre> <p>.. rake routes:</p> <p>I can understand that , I have to use correct if/elses but i am lost in nesting my resources and routing. . Thanks for explanations..</p> <p>These are my edits: In my users_controller: </p> <pre><code>def user_is_friend?(other_user) current_user.friendships.find_by_friend_id(other_user.id) end &lt;% unless user_is_friend?(@user) %&gt; &lt;%= button_to "Add friend", friendships_path(:friend_id =&gt; user), :method =&gt; :post %&gt; &lt;% end %&gt; </code></pre> <p>Is it correct? </p>

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.
