Basic Tests for Forum Implementation - Generating the Controller and View
(Page 2 of 4 )

George has given us a tight schedule. We could create the forum controller and view files manually, but instead, we decide to save some time and use the generate script. Run the generate script with the following parameters to generate the controller:

$ script/generate controller Forum index reply show post create

exists app/controllers/
exists app/helpers/
create app/views/forum
exists test/functional/
create app/controllers/forum_controller.rb
create test/functional/forum_controller_test.rb
create app/helpers/forum_helper.rb
create app/views/forum/index.rhtml
create app/views/forum/reply.rhtml
create app/views/forum/show.rhtml
create app/views/forum/post.rhtml
create app/views/forum/create.rhtml

 

 

 

 

 

 

 

 

 

Note that each action in the controller maps to a user story:

  1. The index action implements the View Forum user story.
  2. The reply action implements the Reply to Post user story. 
     
  3. The show action implements the View Post user story. 
     
  4. The post and create actions implement the Post to Forum user story.

Open app/controllers/forum_controller.rb in your editor. You should see the following code (note that we have left out part of the file):

class ForumController < ApplicationController

  def index
  end

  def reply
  .
  .
end

Next, we will implement each of the forum user stories.
