    <p>Having a very odd problem. I am following the <em>Agile Web Development with Rails (2nd edition)</em> and am currently on the Ajax request iteration. </p> <p><strong>The Problem:</strong> My Application isn't making an AJAX request instead just redirecting to the store_path. </p> <p>My Line Items create actions looks as follows:</p> <pre><code> def create @cart = current_cart product = Product.find(params[:product_id]) @line_item = @cart.add_product(product.id) respond_to do |format| if @line_item.save format.html { redirect_to(store_url) } format.js format.xml { render :xml =&gt; @line_item, :status =&gt; :created, :location =&gt; @line_item } else format.html { render :action =&gt; "new" } format.xml { render :xml =&gt; @line_item.errors, :status =&gt; :unprocessable_entity } end end end </code></pre> <p>And the add to cart looks like this:</p> <pre><code> &lt;%= button_to 'Add to Cart', line_items_path(:product_id =&gt; product),remote: true %&gt; </code></pre> <p>Producing the following form:</p> <pre><code>&lt;form action="/line_items?product_id=3" class="button_to" data-remote="true" method="post"&gt;&lt;div&gt;&lt;input type="submit" value="Add to Cart"&gt;&lt;input name="authenticity_token" type="hidden" value="euZKvTy2ioSTITELTb06ErJZfSeGBuzoMhUyHROvgjI="&gt;&lt;/div&gt;&lt;/form&gt; </code></pre> <p>I have also placed the create.js.rjs in view/line_items directory with the following content:</p> <pre><code>page.replace_html('cart', render(@cart)) </code></pre> <p><strong>EDIT: SERVER LOG</strong><br> Hmm...seems like there is an error in the <code>&lt;%= javascript_include_tag :defaults %&gt;</code> </p> <pre><code>Started GET "/" for 127.0.0.1 at 2013-01-23 17:43:05 -0800 Processing by StoreController#index as HTML Product Load (0.2ms) SELECT "products".* FROM "products" ORDER BY title Cart Load (0.1ms) SELECT "carts".* FROM "carts" WHERE "carts"."id" = ?

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.
