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](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 Maybe the document is a bit outdated.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 ☹

Hi 🙂

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

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 🙂

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 🙂 🙂

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