undefined method?

I'm trying to learn rails as I go along, and having a bit of trouble.
There is an undefined method cropping that I don't know why rails
thinks should be there.

Firstly, I'm using rails 3, ruby 1.9.2

I have a controller with an index action This part works fine, but i
am trying to add a comment form to the page that is rendered by that
index action.

Supposing my controller is named controller1,

I began this process first with:

rails g model comments name:string content:text
rake rb:migrate

Then I went on to define an action to create the comments:

within contoller1_controller.rb I added

You were using a singular resource when you should have defined a plural
one. Also, you can specify the controller on your RESTful route instead
of having to create a separate map.connect or match:

resources :comments, :controller => 'controller1'

I recommend that you use consistent naming with your controllers and
routes though.

HTH

I'm still getting the "undefined method `comments_index_path'" error

The extracted source points at:
  <%= form_for(@comment) do |format| %>

I cannot find where that method would be being called from
even..."comments_index_path" only appears in the development.log

Hmmm wait, I just noticed something. Could you rename your Comments
model to Comment (from plural to singular). Don't forget to rename the
model file (comments.rb to comment.rb)

Thanks, that gets the comment form loading.

I added:

  def create
    @comment = Comment.new(params[:comments])

    respond_to do |format|
      if @comment.save
        format.html { redirect_to('/', :notice => 'comment posted') }
        format.xml { render :xml => @comment, :status
=> :created, :location => @comment }
      else
        format.html { render :action => "new" }
        format.xml { render :xml => @comment.errors, :status
=> :unprocessable_entity }
      end
    end
  end

to my controller1_controller.rb file, and now when I click the submit
button, I get the following error
"uninitialized constant CommentsController"

Despite the redirect_to('/', ...) the page is redirecting to /comments

Can you post your route setup again?

Internet::Application.routes.draw do |map|
  get "internets/index"
  get "section4/index"
  get "section3/index"
  get "section2/index"
  get "section1/index"
  get "science/index"
  resources :users
  resources :comments
  map.connect '/blog/new', :controller => 'section3', :action => 'new'
  get 'login(.:format)' => 'user_session#new', :as => :login
  post 'login(.:format)' => 'user_session#create', :as => :login
  delete 'logout(.:format)' => 'user_session#destroy', :as => :logout
  get "home/index"
  root :to => "home#index"
  map.logout 'logout', :controller => 'user_session', :action =>
'destroy'
  map.logout 'logout', :controller => 'user_session', :action =>
'destroy'
  map.edit 'edit', :controller => 'users', :action => 'edit'
  map.internets 'internets', :controller => 'internets', :action =>
'index'
  map.section4 'random', :controller => 'section4', :action => 'index'
  map.section3 'blog', :controller => 'section3', :action => 'index'
  map.section2 'artistry', :controller => 'section2', :action =>
'index'
  map.section1 'home', :controller => 'section1', :action => 'index'
end

Thats the entirety of it. The area that is giving me trouble is in
the 'section3' controller

I can post comments from the console, and they do then show up in the
index.

and when I use "form_for :comments" the log shows the data being
posted, but there's no INSERT INTO being executed

It seems like the form is not reading from the controller

thanks for the help

I got it to work by creating a comments_controller.rb file and using
the same action definitions as the section3_controller

I'm not sure why i had to make a new controller though.

But, thanks for the help
