    <p><strong>Background and my research</strong></p> <p>I would like to send data from server to client without reloading the page on the browser. I was reading <a href="http://guides.rubyonrails.org/layouts_and_rendering.html" rel="nofollow">Rails guide</a> and using JSON seemed promising. (Correct me if I am wrong).</p> <blockquote> <p>2.2.8 Rendering JSON</p> <p>JSON is a JavaScript data format used by many AJAX libraries. Rails has built-in support for converting objects to JSON and rendering that JSON back to the browser:</p> <p>render :json => @product You don’t need to call to_json on the object that you want to render. If you use the :json option, render will automatically call to_json for you.</p> </blockquote> <hr> <p><strong>Problem</strong></p> <p>I want to be able to render this JSON object back in the browser side. The following are appropriate code for the problem.</p> <p><strong>VideosController</strong></p> <pre><code>class VideosController &lt; ApplicationController include VideosHelper def home @video = Video.last end def next @next_video = next_video(params[:id]) render :json =&gt; @next_video end end </code></pre> <p><strong>next.json.erb</strong></p> <pre><code>{ "title": "&lt;%= @video.title %&gt;" "url": "&lt;%= @video.url %&gt;" "youtube_id": "&lt;%= @video.youtube_id %&gt;" "genre": "&lt;%= @video.genre %&gt;" "category": "&lt;%= @video.category %&gt;" "likes": "&lt;%= @video.likes %&gt;" "dislikes": "&lt;%= @video.dislikes %&gt;" "views": "&lt;%= @video.views %&gt;" "user_id": "&lt;%= @video.user_id %&gt;" "created_at": "&lt;%= @video.created_at %&gt;" "updated_at": "&lt;%= @video.updated_at %&gt;" } </code></pre> <p>If I want to render <code>@next_video</code> JSON object on <code>home</code> action. How do I do this?</p>

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).
