Shared hosts (with Passenger)

2008-12-31T21:04:43-07:00

Several hosting companies now officially support Merb: * Engine Yard * Hosting Rails * Dreamhost If you are looking for a VPS, your best bet is to go with Slicehost or Linode where you have complete control. The most common configurations are Apache with Phusion Passenger or Thin on Nginx.

What's the difference between render and display?

Render In Merb, the render method renders a template. For instance, consider the following controller: class Post < Application provides :json def index render end end If the index action is hit with the HTML mime-type, Merb will look for index.html.*.
