A simple XHTML submit form for ProjectX

jrobertson (James Robertson) — Sun, 13 Apr 2008 22:32:48 GMT

Preparing ProjectX API requests through the browser's address bar can get quite messy, however inputting the request through a simple form makes it much easier to read.

Ajax radio buttons. update the page div when a radio button is pressed.





        

      Sign-up

        

   <% form_for :radio_join, :html => { :id => 'radio_join' } do %>

      <%= radio_button_tag :join_page, :member %> Member

      <%= radio_button_tag :join_page, :model %> Model

      <%= radio_button_tag :join_page, :photographer %> Photographer

    <% end -%>

<% form_for :user, @user, :url => {:action => 'save_free'} do |user_form| -%>

        

    <%= render :partial => 'common/user_form', :object => user_form %>

                

        <%= submit_tag 'JOIN', :class => 'inputSubmit' %>

                

      


      


        

  <% end -%>



     

<%= observe_form :radio_join, :url => { :action => 'choose_page' }, :update => "join", :complete => "Element.show('join')", :frequency => "0.25" %>

Redirect back to a previous action

I am pasting this verbatim from LoginSystem



# move to the last store_location call or to the passed default one

  def redirect_back_or_default(default)

    if @session[:return_to].nil?

      redirect_to default

    else

      redirect_to_url @session[:return_to]

      @session[:return_to] = nil

    end

  end

In your controller...



 redirect_back_or_default :controller => "myfuel", :action => "index"

Firing a controller's action from the console

canadaduane (Duane Johnson) — Fri, 26 Aug 2005 02:44:03 GMT

It seems like a simple task, but here's how you can simulate the calling of a controller's action:



ruby script/console



irb> require 'action_controller/test_process'

irb> require 'application'

irb> require 'site_controller'

irb> request = ActionController::TestRequest.new

irb> response = ActionController::TestResponse.new

irb> request.env['REQUEST_METHOD'] = 'GET'

irb> request.action = "late_employee"

irb> InfoController.process(request,response)

Basically, it's like getting inside of a TestUnit method, but you have to do the dirty work yourself.
