Question

I am working on a project in ruby on rails and I am having a very difficult time with a basic problem. I am trying to call a custom action in one of my controllers, but the request is somehow getting redirected to the default show action and I cannot figure out why.

link in edit.html.erb:

<%= link_to  Mass Text Entry , :action=>"create_or_add_food_item_from_text" %>

Error from development.log:

ActiveRecord::RecordNotFound (Couldn t find Menu with ID=create_or_add_food_item_from_text): app/controllers/menus_controller.rb:20:in `show

routes.rb file:

ActionController::Routing::Routes.draw do |map|
map.resources :nutrition_objects
map.resources :preference_objects
map.resources :institutions
map.resources :locations
map.resources :menus
map.resources :food_items
map.resources :napkins
map.resources :users
map.resource  :session, :controller =>  session 

map.root :controller=> pages , :action=> index 

map.about   /about ,  :controller=> pages , :action=> about 
map.contact  /contact , :controller=> pages , :action=> contact 
map.home    /home ,    :controller=> pages , :action=> index 

map.user_home    /user/home ,   :controller=> rater , :action=> index 
map.user_napkins    /user/napkins , :controller=> rater , :action=> view_napkins 
map.user_preferences   /user/preferences ,:controller=> rater , :action=> preferences 

map.blog    /blog , :controller=> pages , :action=> blog 
map.signup   /signup ,  :controller=> users ,  :action=> new 
map.login   /login ,  :controller=> session , :action=> new 
map.logout   /logout ,  :controller=> session , :action=> destroy 

# Install the default routes as the lowest priority. 
map.connect  :controller/:action 
map.connect  :controller/:action/:id  
map.connect  :controller/:action/:id.:format 
end

Menus_controller.rb:

class MenusController < ApplicationController
...
   def create_or_add_food_item_from_text  
   end
...
end

create_or_add_food_item_from_text.html.erb simply has a div to show a form with a text box in it. I have the rest of my app working fine, but this is stumping me.

Any help is appreciated.

Answer 1

Try adding the route to your file explicitly, before the :menus resources:

map.connect "/menus/create_or_add_food_item_from_text",
  :controller => "menus", :action => "create_or_add_food_item_from_text"

map.resources ...

Routes declared earlier have higher priority, and the problem here is that map.resources actually prevents certain paths from being routed.

Even regardless of this issue, it s good practice to map all paths explicitly, either through resources or named/unnamed routes, and ultimately eliminate the generic :controller/:action and :controller/:action/:id routes from your app.

Answer 2

link_to expects the path to your action as the second parameter - it looks like you are passing link_to the wrong path value. Check the development log to see what path rails thinks you are looking for.
