收到路由错误（路由不匹配）

Question

I am trying to update multi-select list on change but I am getting a routing error. I call this with an onchange event $.post("/levels/category_lists_for_level"

I have an action called category_lists_for_level in a controller called level .

My routes file looks like this.

match '/levels/category_lists_for_level/:id'  => 'levels#category_lists_for_level'
resources :levels 
resources :levels , :collection => {:category_lists_for_level => :get}

What am I doing wrong here? I never had any problem in Rails 2, all I used to add the collection.

It is a bit hard to say exactly what you need since as others have said you are missing some info, but you have a few apparent things going on here:

1. You are duplicating routes
2. You have the route set on a collection and a member
3. You are allowing multiple requests types (get and post) to access this route.

If you would like to have this operate on a collection you just need:

resources :levels do
  post "category_lists_for_level", :on => :collection 
end 

or on a member:

resources :level do 
  get "category_lists_for_level", :on => :member
end

This will reduce your routes. Just use rake routes | grep level rake routes | grep level to get the routes for this controller.

Take a look at this for some more info.
