nested ressource path problem

rubyonrails-talk
1

Hello :-),

I've started to figure out how nested ressources are working, but I get an exception in a (i think so) simple case. The exception is: "ActionController::MethodNotAllowed - Only get, put, and delete requests are allowed."

webrick tells me: 127.0.0.1 - - [19/Jul/2008:04:40:55 CEST] "POST /articles/22/comments/ new HTTP/1.1" 405 7131 http://localhost:3000/articles/22 -> /articles/ 22/comments/new

I see its not a get, put or delete.

routes.rb:   map.resources :comments   map.resources :articles, :has_many => :comments

articles/views/show.html.erb:   <%= link_to_remote("new comment",                      :update => 'editor',                      :url => new_article_comment_path(@article),                      :complete => visual_effect(:blind_down, "editor", :duration => 2.5)) %>

So why didn't I get a get request? Is it a clean code?

I read the RESTful Rails Development from b-simple, but i didn't found a solution for the problem. Maybe the document is a bit outdated. If you have any solution for the problem or a URL I would be glad to hear it *g*

Thanks for reading and have a nice day, Patrick

I also tried: :url => { :controller => "comments", :action => "new", :params => { :article_id => @article}}

But it didn't help me out :frowning:

u can do like this in ur routes file map.resources :articles do |article| article.resources :comments end

in ur view for article in @article ur - stuff — <%= link_to_remote(“new comment”,

                 :update => 'editor',

                 new_article_comment_path(article),

:complete => visual_effect(:blind_down,

“editor”, :duration => 2.5)) %>

end

i hope it helps :slight_smile:

Hi :slight_smile:

thans for your answer, but it didn't helps :-(. I changed the lines in my lines in routes.rb to: map.resources :articles do |article|     article.resources :comments end

(isn't is the old convention?)

And my view to:

<%= link_to_remote("new comment",                      :update => 'editor',                      :url => new_article_comment_path(@article),                      :complete => visual_effect(:blind_down, "editor", :duration => 2.5)) %>

(without ":url =>" in front of, i got a compile error)

But it didn't helps.

Bye, Patrick

:o

opzz

u can do like this in routes.rb map.resources :articles do |article| article.resources :comments end

Hi :slight_smile:

thans for your answer, but it didn’t helps :-(. I changed the lines in

my lines in routes.rb to: map.resources :articles do |article|

article.resources :comments

end

and in ur view

<%= link_to_remote(“new comment”,

                 :update => 'editor',

                 :url => new_article_comments_path(@

article), :complete => visual_effect(:blind_down,

“editor”, :duration => 2.5)) %>

Note: the url will also depend up on the associations that u use in the models if still any issue :o post ur model and routes file

Okay, I post you as much information as i can :slight_smile:

This is my db layout: http://erdbeere.net/media/db_layout.png

article model: class Article < ActiveRecord::Base   belongs_to :blog   has_many :comments end

comment model: class Comment < ActiveRecord::Base   belongs_to :article   belongs_to :user end

routes.rb:   map.resources :users   map.resources :subscriptions   map.resources :blogs # map.resources :comments   map.resources :articles do |article|     article.resources :comments   end

If there is anything i can du to find the problem just send an E- Mails :slight_smile:

un comment the map.resources :comments :slight_smile:

and in the view file

Well, it looks like a problem with js, but I haven't figured out what's wrong. currently i've deactevated the visual effect and use :url to generate the url. It's not great, but it works.

Thanks, Patrick

One Final try :slight_smile:

models/articles.rb has_many :comments models/comments.rb belongs_to :article

controllers comments before_filter :find_article def new @comment = Comment.new

end

def create @comment = Comment.new(params[:comment]) if (@article.comments << @comment) redirect_to article_url(@article) else render :action => :new end

end

private

def find_article @article_id = params[:article_id] return(redirect_to(articles_url)) unless @article_id @article = Article.find(@article_id) end

views/comments/new.html.erb

<% form_for [@article, @comment] do |form| %>

Add a Comment

<%= render :partial => ‘form’, :object => form %>

<%= submit_tag "Create" %>

<% end %>

And Finally ur routes file should be

ActionController::Routing::Routes.draw do |map| map.resources :articles do |article|

article.resources :comments

end

I hope it will work out :slight_smile: :slight_smile:

if u still face any issue :o u can ask regards, Balu
