Which tutorial was this in?

[khristian]

Steve,

It was in JSBlogger: http://tutorials.jumpstartlab.com/projects/jsblogger.html

[steveklabnik]

Hm. article_path should be correct there. Can you show me what your routes.rb file has in it?

[khristian]

Thanks for looking into this Steve.

My routes.rb file is:

Jsblogger::Application.routes.draw do
#create a resource names articles
resources :comments
resources :articles

The priority is based upon order of creation:

first created -> highest priority.

Sample of regular route:

match 'products/:id' => 'catalog#view'

Keep in mind you can assign values other than :controller and :action

Sample of named route:

match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase

This route can be invoked with purchase_url(:id => product.id)

Sample resource route (maps HTTP verbs to controller actions automatically):

resources :products

Sample resource route with options:

resources :products do

member do

get 'short'

post 'toggle'

end

collection do

get 'sold'

end

end

Sample resource route with sub-resources:

resources :products do

resources :comments, :sales

resource :seller

end

Sample resource route with more complex sub-resources

resources :products do

resources :comments

resources :sales do

get 'recent', :on => :collection

end

end

Sample resource route within a namespace:

namespace :admin do

# Directs /admin/products/* to Admin::ProductsController

# (app/controllers/admin/products_controller.rb)

resources :products

end

You can have the root of your site routed with "root"

just remember to delete public/index.html.

root :to => 'welcome#index'

See how all your routes lay out with "rake routes"

This is a legacy wild controller route that's not recommended for RESTful applications.

Note: This route will make all actions in every controller accessible via GET requests.

match ':controller(/:action(/:id(.:format)))'

end

Here are my routes:

Ping:jsblogger admin$ rake routes
comments GET /comments(.:format) {:action=>"index", :controller=>"comments"}
POST /comments(.:format) {:action=>"create", :controller=>"comments"}
new_comment GET /comments/new(.:format) {:action=>"new", :controller=>"comments"}
edit_comment GET /comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}
comment GET /comments/:id(.:format) {:action=>"show", :controller=>"comments"}
PUT /comments/:id(.:format) {:action=>"update", :controller=>"comments"}
DELETE /comments/:id(.:format) {:action=>"destroy", :controller=>"comments"}
articles GET /articles(.:format) {:action=>"index", :controller=>"articles"}
POST /articles(.:format) {:action=>"create", :controller=>"articles"}
new_article GET /articles/new(.:format) {:action=>"new", :controller=>"articles"}
edit_article GET /articles/:id/edit(.:format) {:action=>"edit", :controller=>"articles"}
article GET /articles/:id(.:format) {:action=>"show", :controller=>"articles"}
PUT /articles/:id(.:format) {:action=>"update", :controller=>"articles"}
DELETE /articles/:id(.:format) {:action=>"destroy", :controller=>"articles"}

[steveklabnik]

of course!

article GET /articles/:id(.:format) {:action=>"show", :controller=>"articles"}

Yeah. Should be article_path(article). How strange. Could you maybe upload the app to a repo so I could play around with it?

[khristian]

Steve,

Try this: https://github.com/khristian/test

This is the first time I've created a repo so let me know if this isn't what you need.

Thanks again.

[steveklabnik]

That's great! Looking at it now.

[steveklabnik]

Turns out the problem is unrelated, and this is just a really, really poor error message:

https://github.com/khristian/test/blob/master/app/controllers/comments_controller.rb#L4

This should be Comment.new(params[:comment]), because params[:article] is nil. When it's nil, and you try to give nil to comment_path, it throws that error. Which is dumb.

Let me know if I can help clear up any confusion about this.
