Man, I have been trying to figure this one out for hours, hopefully
you guys can clue me in.
Let’s so you have three “nested” models, for example: Category -> Post
-> Comment (that is, many comments belong to one post and many posts
belong to one category).
So, in your routing configuration you have:
map.resources :categories do |cat|
cat.resources :posts, :has_many => :comments
The part I cant figure out, is how to write a “form_for” helper so
that the HTML action="" attribute will end up being “categories/1/
posts/1/comments”. The farthest I can seem to get is “posts/1/
comments”, which, I could proly skate by with, but I’d really like to
get the entire nested route in their. (I’ve seen that the rails app
“Basecamp” is able to accomplish this, so it has to be possible).
These are a couple of the things I’ve tried, both result in an error:
- form_for([:category, @post, Comment.new]) do |f|
- form_for @post, :url => new_category_post_comment_path do |f|
What am I doing wrong here!? Thanks guys.
