i try to fill twice id in url, but when i send params twice id just one id fill the url id.
My route :
namespace :admin do
resources :stores
get "/:id/new_items"=> 'stores#new_items', as: :store_new_items
post "/:id/create_items"=> 'stores#create_items', as: :store_create_items
get "/:id/show_items/:id"=> 'stores#show_items', as: :store_show_items
get "/:id/items/:id/new_items_sub" => 'stores#new_items_sub', as: :store_new_items_sub
post "/:id/items/:id/create_items_sub" => 'stores#create_items_sub', as: :store_create_items_sub
get "/:id/items/:id/show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
end
my view :
<%= link_to "add new items", admin_store_new_items_sub_path(#store.id, #items.id), :class=> "btn" %>
i hope my url like this :
http://localhost:3000/admin/#{store.id}/items/#{items.id}/new_items_sub
but i get same id like this :
http://localhost:3000/admin/#{store.id}/items/#{store.id}/new_items_sub
please tell me when i'm wrong? thanks
you have to create neseted routes for that .have a look at
http://guides.rubyonrails.org/routing.html#nested-resources
for example
resources :publishers do
resources :magazines do
resources :photos
end
end
will accept routes /publishers/1/magazines/2/photos/3
Your params should be unique, so you can't pass more than one different :id params. Instead. you can do something like:
get '/:store_id/show_items/:id', as: :store_show_items
and in view:
<%= link_to 'show items', store_show_items_path(#store.id, #item.id) %>
Also, you should read more about Resources and Nested Resources in Rails, there's probably no need to complicate your life by creating each route independently.
You could refactor this to use nested routes like this (you may have to change controller method names):
namespace :admin do
resources :stores do
resources :items, :only => [:new, :create, :show] do
resources :subs, :only => [:new, :create, :show]
end
end
end
This would give you a few url helpers like this: new_store_item_sub_path(#store.id, #item.id) for the new action and store_item_sub_path(#store.id, #item.id, #sub.id) for the show action.
Run rake routes to see what helpers and routes you have access to.
Have a look here to find out more about nested routes.
Your code can be DRYed up significantly. Hopefully this works; might need some tweaking:
namespace :admin do
resources :stores do
member do
get :new_items, as: :store_new_items
post :create_items, as: :store_create_items
end
get "show_items/:id"=> 'stores#show_items', as: :store_show_items
resources :items do
get :new_items_stub => 'stores#new_items_sub', as: :store_new_items_sub
post :create_items_stub => 'stores#create_items_sub', as: :store_create_items_sub
get "show_items_sub/:id" => 'stores#show_items_sub', as: :store_show_items_sub
end
end
end

Nested Resources
The crux of your issue is that you're trying to pass the :id param twice
Fortunately, Rails has a solution to this, in the form of Nested Resources. These work by taking the "parent" id and prepending a singular prefix, such as :store_id, allowing you to use the :id param for another set of methods

I have a subscriptions controller with routes that look like this:
get 'user/:user_id/subscription_requests' => 'subscriptions#index', as: :subscription_requests
post 'user/:user_id/subscribe' => 'subscriptions#subscribe', as: :user_subscribe
post 'user/:user_id/unsubscribe' => 'subscriptions#unsubscribe', as: :user_unsubscribe
post 'user/:user_id/request_subscription' => 'subscriptions#request_subscription', as: :request_user_subscription
post 'user/:user_id/accept_subscription' => 'subscriptions#accept', as: :accept_subscription_request
post 'user/:user_id/reject_subscription' => 'subscriptions#reject', as: :reject_subscription_request
All of them except index are non-restful actions. How do you make this cleaner in the routes file using something like resources while keeping the user/:user_id/ in the path?
Update for clarity:
I'm trying to avoid listing the routes line by line and instead do something like what rails provides with the restful actions. Something like:
resources :subscription_requests, :only => [:subscribe, :unsubscribe, :reject, :accept, etc]
You can use the member function of routing.
resources :user, to: 'subscriptions', :only => [] do
member do
get 'subscription_requests'
post 'subscribe'
etc
end
end
And this will produce routes such as:
subscription_requests_user GET /user/:id/subscription_requests(.:format) subscriptions#subscription_requests
subscribe_user POST /user/:id/subscribe(.:format) subscriptions#subscribe

I'm trying to call a custom controller action shuffle for a resource that is nested within another resource. I can't seem to get the method call right.
routes.rb
resources :templates do
resources :items
end
match "/templates/:template_id/items/shuffle" => "items#shuffle"
I have a link in my items#index view:
<%= link_to 'Shuffle', shuffle_template_items_path(#template) %>
When I click on the link, I get the following error:
undefined method `shuffle_template_items_path' for #<#<Class:0x42577c8>:0x3e77578>
I have also tried <%= link_to 'Shuffle', template_items_shuffle_path(#template) %> and that did not work.
How do I correctly call this custom action?
You probably want this:
resources :templates do
resources :items do
get :shuffle, :on => :collection
end
end
If you want your custom action to have a name, you need to provide it:
match "/templates/:template_id/items/shuffle" => "items#shuffle", :as => :suffle_template_items
I think the best way to write shuffle is in collection as per the documentation of Rails Routes:
So it would looks like this:
resources :templates do
resources :items do
collection do
get :shuffle
end
end
end
when you try rake routes you will find shuffle_template_items GET /templates/:template_id/items/shuffle(.:format) items#shuffle.
Currently I have something like this:
resources :books do
collection do
get 'search'
end
end
and my controller name is also "books" and I have a action method called "search" inside it
I would like that "get search" part to also be a resource, kind of like nested resources... but I don't want to break other peoples codes that are using the current route that this generate, so need to update it in a passive way!
resources :books do
collection do
get 'search'
end
resources :searches
end
...if I'm understanding you correctly, that should be what you want. It won't break other routes, just add new ones.
Run rake routes to make sure you have all the routes you want/need.
Use shallow routes nesting like:
resources :books , :shallow => true do
resources :searches
end
Now you will get the following routes:
/books/1 => books_path(1)
/books/1/searches => books_searches_index_path(1)
/searches/2 => searches_path(2)
Similarly you can get separate routing for defined routes like:
get '(:books)/searches', :to => 'books#index'
How do I rename some of these routes...for example, below i want to use signup_path in my controllers instead of signup_sessions_path...
resources :sessions, only: [] do
collection do
post :signup, :as => :signup
post :login
delete :logout
end
end
Try not to nest the routes under resources :sessions but rather use the to: option like so:
post :signup, to: 'sessions#signup', as: :signup, on: :collection
Not too sure about your collection there but I'm sure you get the gist of it
Update
According to your comment, as of today, I don't know of any way to remove the nested route resource name from the path name of a nested resource route. In other words, whatever is nested is purposely to use the scope of the resource and therefore there are no options to revert that behaviour other than taking it out of the resource's block.
In my AdminController, I have methods named as edit, update and update_admin. And in route.rb
resources :session, :only => [update]
match '/:controller(/:action(/:id))'
end
When I navigate the url '/users/edit/1' matches. From this page i want to call the action method in update_admin in AdminController. How to do this?
My edit.erb has
<%= render :partial => '/submit', :locals =
> {:button_html => f.submit('Update'), :validate_present => true}
%>
at first, to check your routes go to console and do
rake routes | grep session
there you will get list all routes of your rails application (matched to the grep)
at second i dont get your routes.rb
would you do
resources :session, :only => [update] do
match '/:controller(/:action(/:id))'
end
or
resources :session, :only => [update]
match '/:controller(/:action(/:id))'
end
these are 2 different things. i think you want the last one. but here we go, there is another problem
resources :session, :only=>[update]
this throws an error.(undefined local variable or method `update' for #)
if you want to specify actions, you need to do it as a key
resources :session, :only=>[:update]
but you also want the edit message, (edit is the form, update the action to save the changes) so you have to do
resources :users, :only=>[:edit, :update]
now check your rake routes and see voila!
edit_session GET /session/:id/edit(.:format) {:action=>"edit", :controller=>"session"}
session PUT /session/:id(.:format) {:action=>"update", :controller=>"session"}
//edit
if you want to do this in your admin_controller you should have a namespace
#i take example for a user
namespace :admin do
resources :user :only => [:edit, :update]
end
if you want now to link to it from a view the route is named
edit_admin_user_path
and in a form you need to bring the namespace also in the form_for like:
=form_for [:admin, #user] do |f|
