    <p>A nod to James on this, as it helped me get our mailer working right.</p> <p>A slight refinement to this: First, we use the block arguments within the blocks to add parts (I had problems when I didn't). </p> <p>Also, if you want to use layouts, you have to use #render directly. Here's an example of both principles at work. As shown above, you need to make sure you keep the html part last.</p> <pre><code> def message_with_attachment_and_layout( options ) from options[:from] recipients options[:to] subject options[:subject] content_type "multipart/mixed" part :content_type =&gt; 'multipart/alternative' do |copy| copy.part :content_type =&gt; 'text/plain' do |plain| plain.body = render( :file =&gt; "#{options[:render]}.text.plain", :layout =&gt; 'email', :body =&gt; options ) end copy.part :content_type =&gt; 'text/html' do |html| html.body = render( :file =&gt; "#{options[:render]}.text.html", :layout =&gt; 'email', :body =&gt; options ) end end attachment :content_type =&gt; "application/pdf", :filename =&gt; options[:attachment][:filename], :body =&gt; File.read( options[:attachment][:path] + '.pdf' ) end </code></pre> <p>This example uses an options hash to create a generic multipart message with both attachments and layout, which you would use like this:</p> <pre><code>TestMailer.deliver_message_with_attachment_and_layout( :from =&gt; 'a@fubar.com', :to =&gt; 'b@fubar.com', :subject =&gt; 'test', :render =&gt; 'test', :attachment =&gt; { :filename =&gt; 'A Nice PDF', :path =&gt; 'path/to/some/nice/pdf' } ) </code></pre> <p>(We don't actually do this: it's nicer to have each mailer fill in a lot of these details for you, but I thought it would make it easier to understand the code.)</p> <p>Hope that helps. Best of luck.</p> <p>Regards, Dan</p>

    1. COThanks. Your answer and the [Ruby Guide](http://guides.rubyonrails.org/v2.3.11/action_mailer_basics.html#sending-multipart-emails-with-attachments) helped me solving a similar issue with multipart email and attachment.

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.
