list and create on one page rails 3

Question

I want to make a dashboard page with on top a create action (form) and underneath it a list action... (to display all the questions that have been made) I was wondering what is the best way to do this.

I have a QuestionsController with a list and a create action. So i do need to make a DashboardController with a createlist action...? And there render the two templates from the QuestionController...?

Or do i need to make a DashboardController with both the list and create actions on them refering to the Questions model?

Best regards, Thijs

Answer 1

You should create QuestionsController, with form partial included on index view. This form should simply follow to create action, and this action should at error (remember that there could be validation errors) render index action, and after success it should redirect back to index.

Unless you also need to create questions from other places, then it's more complicated.

UPDATE:

You could also create DashboardsController, but I would only use it to display dashboard (show action and singular resource, not resources in routes.rb), and then normally follow new question form to QuestoinsController#create, and redirect back to DashboardsController#show. This way it's more RESTful if you also show more than one resource type on dashboard, because you show singular dashboard (with questions and other resources), but you follow to QuestionsController#create to create Question.

UPDATE 2:

To make it in one place if you (or anyone else needs):

1. In your routes.rb file define resources:

   resources :questions
   

2. In your QuestionController:

   class QuestionsController < ApplicationController
     def index
       setup_questions
     end
   
     def create
       @question = Question.new(params[:question])
       if @question.save
         redirect questions_path, :notice => "Successfully created question."
       else
         setup_questions
         render :action => :index
       end
     end
   
     private
   
     def setup_questions
       @questions = Question.order(:name).page(params[:page])
       # or any other method to fetch all your questions
   
       @question ||= Question.new
     end
   end
   

3. In your app/views/questions/index.html.erb view:

   <% @questions.each do |question| %>
     <%# display question as table row %>
   <% end %>
   
   <% render :template => "form", :locals => {:question => @question} %>
   

4. in app/views/questions/_form.html.erb you just define your standard form for new question:

   <%= form_for question do |f| %>
     <%# form fields %>
   <% end %>
   

Then you don't need view for new action, as this action would just display form for new question, and you have this form in index action.

Answer 2

You can combine both of this at, for ex., index page. Biuld form with form_for(@question) block and display collection of @questions uder it. For sure you should define @question and @questions in index action of controller.
