    <p>I'm trying to add a table to my app but when I do I get the error shown below. But I don't understand why? All I did was adding the Recommendation class.</p> <pre><code>class Item include DataMapper::Resource property :id, Serial property :sortorder, Integer property :title, Text property :company, String property :desc, Text property :year, Integer property :url, String mount_uploader :source, ImageUploader end class Recommendations include Datamapper::Resource property :id, Serial property :firstname, String property :lastname, String property :title, String property :mugshot, String property :text, Text end configure :development do DataMapper.auto_upgrade!

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).
