    <p>I'm using Rails 3.0.9 and jQuery 1.6.2 with jQuery-ujs.</p> <p>Basically I'd like to ajaxfy my "add to cart" action.</p> <p>In my view:</p> <pre><code>&lt;td&gt;&lt;%= button_to "Add to cart", line_items_path(:coupon_id =&gt; coupon, :format =&gt; :js), :remote =&gt; true %&gt; </code></pre> <p>In my controller:</p> <pre><code>def create @cart = current_cart coupon = Coupon.find(params[:coupon_id]) @line_item = @cart.add_coupon(coupon.id) respond_to do |format| if @line_item.save format.html { redirect_to(@line_item.cart) } format.js {render :layout =&gt; false, :content_type =&gt; 'text/javascript'} format.xml { render :xml =&gt; @line_item, :status =&gt; :created, :location =&gt; @line_item } else format.html { render :action =&gt; "new" } format.js {render :layout =&gt; false, :content_type =&gt; 'text/javascript'} format.xml { render :xml =&gt; @line_item.errors, :status =&gt; :unprocessable_entity } end end </code></pre> <p>end</p> <p>I've also created a create.js.erb:</p> <pre><code>$("#my_cart").html("&lt;%= escape_javascript(render(:partial =&gt; 'layouts/mycart')) %&gt;"); </code></pre> <p>to update the cart item number whenever a new item is added.</p> <p>When I click the "add to cart" button, a JS POST request is sent to the server:</p> <pre><code> Started POST "/line_items.js?coupon_id=1" for 127.0.0.1 at Thu Aug 18 00:04:31 +0800 2011 Processing by LineItemsController#create as JS </code></pre> <p>And the response from the server is:</p> <pre><code>Rendered layouts/_mycart.html.erb (5.3ms) Rendered line_items/create.js.erb (28.9ms) Completed 200 OK in 127ms (Views: 58.7ms | ActiveRecord: 3.0ms) </code></pre> <p>The response's body contains the javascript code to update my cart:</p> <pre><code>$("#my_cart").html("&lt;li id=\"my_cart\"&gt;&lt;a href=\"/carts/10\"&gt;My cart(1)&lt;\/a&gt;\n&lt;\/li&gt;"); </code></pre> <p>However, the web page is not updated. I tried different browsers (Chrome, Firefox, Safari). But if I manually run this code in Firebug's console, the page got updated. I've googled for a day and tried different solutions. None of them worked me. Could someone solve my problem?</p> <p>Here's the code generated for button_to:</p> <pre><code>&lt;form method="post" action="/line_items.js?coupon_id=1" data-remote="true" class="button_to"&gt;&lt;div&gt;&lt;input type="submit" value="Add to cart" /&gt;&lt;input name="authenticity_token" type="hidden" value="MdHScf0JVNu2UFXLxuindDvZ5TPBztfMMzv57w1LWX8=" /&gt;&lt;/div&gt;&lt;/form&gt; </code></pre>

    3. COI tried alert() before and got same result: the javascript is returned from the server but not executed by the browser. I have to manually execute the code in Firebug's console to trigger the alert box.

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).
