    <p>I am having difficulty translating the Headfirst into Rails book which is based on Rails 2 into Rails 4 which is set up on my machine. The exercise is trying to retrieve a record from a database and then, once edited, update the table. I have tried many different ways and my current configuration is as follows - this will present the record for editing but will not actually update the record! (Infuriating!) NB - I am not using 'strong_parameters' nor 'protected_attributes' - I did try this but was getting stack to deep and other errors. My ad model is also empty - I have removed the att_accessible entries that I tried with the protected attributes gem.</p> <p>Here is my - ad controller entry:</p> <pre><code>def update @ad = Ad.find(params[:id]) @ad.update_attributes(update_params[:id]) redirect_to "/ads/#{@ad.id}" end private def update_params params.permit(:name, :description, :price, :seller_id, :email, :ad, :img_url) end end </code></pre> <p>EDIT VIEW:</p> <pre><code>&lt;h1&gt;Editing &lt;%= @ad.name %&gt;&lt;/h1&gt; &lt;%= form_for(@ad,:url=&gt;{:action=&gt;'update'}) do |f| %&gt; &lt;p&gt;&lt;b&gt;Name&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_field :name %&gt;&lt;/p&gt; &lt;p&gt;&lt;b&gt;Description&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_area :description %&gt;&lt;/p&gt; &lt;p&gt;&lt;b&gt;Price&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_field :price %&gt;&lt;/p&gt; &lt;p&gt;&lt;b&gt;Seller&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_field :seller_id %&gt;&lt;/p&gt; &lt;p&gt;&lt;b&gt;Email&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_field :email %&gt;&lt;/p&gt; &lt;p&gt;&lt;b&gt;Img Url&lt;/b&gt;&lt;br /&gt;&lt;%= f.text_field :img_url %&gt;&lt;/p&gt; &lt;p&gt;&lt;%= f.submit "update" %&gt;&lt;/p&gt; &lt;% end %&gt; </code></pre> <p>Log Entry on Update:</p> <pre><code> Started PATCH "/ads/1/update" for 127.0.0.1 at 2013-08-13 22:35:51 +0100 Processing by AdsController#update as HTML Parameters: {"utf8"=&gt;"V", "authenticity_token"=&gt;"O4cN72FXCCkfkL7M6bozodbB0Aqor NctOOV5sfXdado=", "ad"=&gt;{"name"=&gt;"Typewriter", "description"=&gt;"Old manual typewr iter.

    1. COLook at this line; You're calling `update_params` incorrectly: `@ad.update_attributes(update_params[: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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
