    <p>I'm new to Ruby and Ruby on Rails.</p> <p>I'm making a sample app (not using scaffolding) to insert a row into a table. Table has 2 columns, "name" and "description" (along with the 3 magic columns).</p> <p>In my view, I have something that looks like this:</p> <pre><code>&lt;h1&gt;New Location&lt;/h1&gt; &lt;%= form_for(@location) do |l| %&gt; &lt;div class="field"&gt; &lt;%= l.label :name %&gt;&lt;br /&gt; &lt;%= l.text_field :name %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= l.label :description %&gt;&lt;br /&gt; &lt;%= l.text_field :description %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= l.submit "Add" %&gt; &lt;/div&gt; </code></pre> <p>And controller:</p> <pre><code>class LocationsController &lt; ApplicationController def new @location = Location.new end def create @location = Location.new(params[:location]) @location.save #fails on this line redirect_to @location end end </code></pre> <p>Model code:</p> <pre><code>class Location &lt; ActiveRecord::Base attr_accessible :name, :description has_many :foods end </code></pre> <p>This is what the console prints out:</p> <pre><code>Started POST "/locations" for 127.0.0.1 at Wed Jan 25 17:09:22 -0500 2012 Processing by LocationsController#create as HTML Parameters: {"commit"=&gt;"Add", "location"=&gt;{"name"=&gt;"name", "description"=&gt;"description"}, "authenticity_token"=&gt;"7rT1/3qSn/Kz1cGg8iTFCKbkO0W/L7ETT+lNcSSN6FI=", "utf8"=&gt;"\342\234\223"} (0.1ms) begin transaction SQL (5081.3ms) INSERT INTO "locations" ("created_at", "description", "name", "updated_at") VALUES (?, ?, ?, ?)

    1. COPlease add the full stack trace if you can. The code looks on first glance like it should work, so more context for the error would be helpful.

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).
