Why am I seeing this page?

+

Merb couldn't find an appropriate content_type to return, + based on what you said was available via provides() and + what the client requested.

+ +

How to add a mime-type

+ 

+      Merb.add_mime_type :pdf, :to_pdf, %w[application/pdf], "Content-Encoding" => "gzip"
+
+

What this means is:

+
    +
  • Add a mime-type for :pdf
    • +
  • Register the method for converting objects to PDF as #to_pdf.
    • +
  • Register the incoming mime-type "Accept" header as application/pdf.
    • +
  • Specify a new header for PDF types so it will set Content-Encoding to gzip.
    • +
+ +

You can then do:

+ 

+      class Foo < Application
+        provides :pdf
+      end
+
+ +

Where can I find help?
