    <p><strong>Gemfile</strong></p> <pre><code>gem 'prawn' </code></pre> <p><strong>/config/initializers/mime_types.rb</strong></p> <pre><code>Mime::Type.register "application/pdf", :pdf </code></pre> <p><strong>AuditsController</strong></p> <pre><code>def show @audit = Audit.find(params[:id]) respond_to do |format| format.html format.pdf do pdf = Prawn::Document.new pdf.text "This is an audit." # Use whatever prawn methods you need on the pdf object to generate the PDF file right here. send_data pdf.render, type: "application/pdf", disposition: "inline" # send_data renders the pdf on the client side rather than saving it on the server filesystem. # Inline disposition renders it in the browser rather than making it a file download. end end end </code></pre> <p>I used to use the <code>prawnto</code> gem before Rails 3.1, but it doesn't work without a bit of hacking anymore. This is a much cleaner way to instantiate and display the PDF object in 3.1 by accessing Prawn directly.</p> <p>I got this technique straight from one of Ryan Bates' <a href="http://www.railscasts.com" rel="noreferrer">Railscasts</a>. Been using it ever since. You can view that specific episode <a href="http://railscasts.com/episodes/153-pdfs-with-prawn-revised" rel="noreferrer">here</a>. He goes into much more detail about subclassing Prawn and moving the PDF generating code out of the controller. Also shows a lot of useful Prawn methods to get you started. Highly recommended.</p> <p>A lot of the episodes are free, but that revised Prawn episode is one of those that are only available with a paid subscription. At $9/month though, a subscription quickly pays for itself.</p>

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).
