Rescue from dispatching, layout mailer

Rescue from dispatching
人家這個sample 太好 不知道要講啥 XD
<br />class ApplicationController < ActionController::Base<br /> rescue_from ActionController::RoutingError, :with => :route_not_found<br /> rescue_from ActionController::MethodNotAllowed, :with => :invalid_method<br /> <br /> private<br /> <br /> def route_not_found<br /> render :text => 'What the fuck are you looking for ?', :status => :not_found<br /> end<br /> <br /> def invalid_method<br /> message = "Now, did your mom tell you to #{request.request_method.to_s.upcase} that ?"<br /> render :text => message, :status => :method_not_allowed<br /> end<br />end<br />
Mailer Layouts
default 他會找 layout 裡 加上 _mailer的, 像這邊就是會去找layouts/user_mailer.html.erb <br />class UserMailer < ActionMailer::Base<br /> def registration(user)<br /> subject "You've registered"<br /> from "system@example.com"<br /> end<br />end<br />
當然也可以自己指定 layou
<br />class UserMailer < ActionMailer::Base<br /> layout 'email'<br /> ...<br />end<br />

[config/environments/development.rb]     
config.action_controller.consider_all_requests_local = false

#  force the request connect from outside
def local_request?
  false

#有上面兩個條件rescue_action_in_public才可以在local測
def rescue_action_in_public(exception)
  case exception

    redirect_to home_url

<%= stylesheet_link_tag "defaults",  "paginator", :cache => 'css_cache' %>
<%= javascript_include_tag "jquery", "jquery.corner.js", "jquerypngfix.js", :cache => 'js_cache' %>

上述的這些 :cache 功能 如果 client ip 是從 local來 就不會跑, 不會生出 css_cache.css 或 js_cache.js
