    <p>I am trying to create a token field using the TokenInput plugin to add members (only the friends of the user creating the group) to a group.</p> <p>So, I have my friendships controller code here:</p> <pre><code>class FriendshipsController &lt; ApplicationController def index @friend_list = @current_user.friends.map { |f| {:id =&gt; f.id, :name =&gt; f.first_name + ' ' + f.last_name}} respond_to do |format| format.html # index.html.erb format.json { render json: @friend_list } end end </code></pre> <p>This returns an array, like below, at the url "/friendships.json":</p> <pre><code>[{"id":6,"name":"John Smith"},{"id":7,"name":"Jane Doe"}] </code></pre> <p>Then, I have my form, with the jquery for TokenInput below it:</p> <pre><code> &lt;%= form_for(@group) do |f| %&gt; &lt;div class="field"&gt; &lt;%= f.label :group_name, "Name" %&gt;&lt;br /&gt; &lt;%= f.text_field :group_name %&gt; &lt;/div&gt; &lt;div class="ui_widget"&gt; &lt;%= f.label :member_tokens, "Members" %&gt;&lt;br /&gt; &lt;%= f.text_field :member_tokens %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= f.submit %&gt; &lt;/div&gt; &lt;% end %&gt; &lt;script&gt; $(function() { $('#group_member_tokens').tokenInput("/friendships.json"); }); &lt;/script&gt; </code></pre> <p>My question is, how do I filter the array at /friendships.json? I have tried doing the following in my FriendshipsController:</p> <pre><code>friend_list = @current_user.friends.map { |f| {:id =&gt; f.id, :name =&gt; f.first_name + ' ' + f.last_name}} @friend_list = friend_list.where("name LIKE ?", "%#{params[:q]}%") </code></pre> <p>... but this only returns an empty array at /friendships.json.</p> <p>If anyone could let me know why this is returning an empty array I would greatly appreciate it.</p> <p><strong>UPDATE:</strong></p> <p>I tried doing this:</p> <pre><code> @friend_list = @user_name.friends.where("name LIKE ?", "%#{params[:q]}%") @friend_list = @friend_list.map { |f| {:id =&gt; f.id, :first_name =&gt; f.first_name + ' ' + f.last_name}} </code></pre> <p>... but when I add the code ".where("name LIKE?", "%#{params[:q]}%")" to the end of @friend_list = current_user.friends, then I no longer get any autocomplete results in the TokenInput field (it returns "No Results").</p> <p>When I manually enter the q param into the URL, for example "http://localhost:3000/friendships.json?q=k" ... I end up with an empty array. This is weird because a User with first_name Kevin is in my application. </p> <p>Here is what is outputted on my ruby server:</p> <pre><code>Started GET "/friendships.json?q=ke" for 127.0.0.1 at 2012-09-16 19:27:53 -0400 Processing by FriendshipsController#index as JSON Parameters: {"q"=&gt;"ke"} [...] User Load (0.7ms) SELECT "users".* FROM "users" INNER JOIN "friendships" ON "users"."id" = "friendships"."friend_id" WHERE "friendships"."user_id" = 2 AND (first_name LIKE '%ke%') [...] </code></pre> <p>HOWEVER, I just tried typing in "evin" into the tokenInput text_field, and it found the user. For some reason the q parameter can't find the first letter of the user's first_name. Anyone have any thoughts on this?</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.
