has_many, belongs_to and comment forms
- by Koning Baard XIV
I'm having two models: Snippet and SnippetComment. These also have their own controllers, as well as views. In /app/views/snippets/show.html.erb I have a form that starts like this:
<% form_for(@new_snippet_comment) do |form| %>
SnippetComment belongs to one Snippet, and a Snippet belongs to one User. This means that I have this routing:
map.resources :users do |user|
user.resources :snippets do |snippet|
snippet.resources :snippet_comments, :as => "comments"
end
end
So when I submit the SnippetComment form in the SnippetController#show view, this request should be made:
POST /users/x/snippets/x/comments HTTP/1.1
(where x is the User's or Snippet's id).
The problem is that I don't even get the comment submission form, but rahter this:
NoMethodError in Snippets#show
Showing
app/views/snippets/show.html.erb where
line #29 raised:
undefined method `snippet_comments_path' for
Extracted source (around line #29):

32: <%= form.text_area :body %>
