Encapsulates the notion of a mime type. Can be used at render time, for example, with:
class PostsController < ActionController::Base def show @post = Post.find(params[:id]) respond_to do |format| format.html format.ics { render :text => post.to_ics, :mime_type => Mime::Type["text/calendar"] } format.xml { render :xml => @people.to_xml } end end end
