In a ruby on rails app, I have the following routes file:
Rails.application.routes.draw do
get 'pages/index'
get 'pages/about'
root to: 'pages#index'
resource :graphs, only: [:index, :create, :show, :destroy]
end
This generates the routes for graphs#create, graphs#show, graphs#destroy but not for graphs#index. I think the reason for this is that when I generated the controller I used rails g controller Graph, i.e. I used the singular version instead of the plural of Graphs. To fix this I changed the corresponding file and directory names i.e. controller/graphs_controller.rb and views/graphs, and I changed the constant in graphs_controller.rb to GraphsController. Everything seems to work except for the index route not being generated. I can fix it by changing the resource declaration to
resource :graphs, only: [:create, :show, :destroy] do
get :index
end
but this seems messy. It seems I need to change something else to make the transition from graph to graphs. How do I fix this? Note that I have restarted the server several times.
Use resources instead of resource:
Rails.application.routes.draw do
get 'pages/index'
get 'pages/about'
root to: 'pages#index'
resources :graphs, only: [:index, :create, :show, :destroy]
end
It should be resources instead of resource

I get a weird behavior when trying to do a super easy task:
adding
resources :something do
...
end
to the routes.rb generates all routes except #new.
when trying to browse 'localhost:3001/somethings/new' it handled by #show action.
I'm using rails 5.1.4 version. Any ideas?
======== UPDATE ========
I added s and still have the same problem: Here is the full code example and the result:
namespace :api do
namespace :webapp do
resources :user do
resources :documents
end
end
end
I was able to make it work when added:
resources :documents , only: [:show, :index, :update, :edit, :new, :create]
I have simple controller and routes file.
In my route and controller i have created a module. I wrote a simple method which is redirecting me show. I am not sure why.
Controller
module Seller
class CampaignsController < Seller::BaseController
before_action :confirm_logged_in
def viewAllCampaigns
#campaigns = Campaign.all
end
def show
end
end
end
Routes file
scope module: 'seller' do
#namespace :power do
resources :dashboard, only: [:index]
resources :sessions, only: [:create, :destroy]
resources :campaigns, only: [:index, :create, :show, :update, :destroy]
get 'viewAllCampaigns' => 'campaigns#viewAllCampaigns'
end
Output
Started GET "/campaigns/viewAllCampaigns" for 127.0.0.1 at 2015-10-12 17:39:43 +0500
Processing by Seller::CampaignsController#show as HTML
Parameters: {"id"=>"viewAllCampaigns"}
Rendered seller/campaigns/show.html.erb (0.1ms)
I am hitting http://localhost:3000/campaigns/viewAllCampaigns in browser.
Ideally your routes should be defined like this.
resources :campaigns, only: [:index, :create, :show, :update, :destroy] do
get 'viewAllCampaigns', on: :collection
end
The first comment on the routes.rb file is The priority is based upon order of creation: first created -> highest priority. This is the reason your route is redirecting to show. Rails is treating this url as campain/:id.
Routes are tested in order, from top to bottom. The show route you've added for the campaigns resource will look for urls matching this pattern:
/campaigns/:id
/campaigns/viewAllCampaigns matches this, so it will do the show action., with params[:id] = "viewAllCampaigns"
Move the special case route up above the resources#campaigns route to fix this, then it will catch the url first.
get 'viewAllCampaigns' => 'campaigns#viewAllCampaigns'
resources :campaigns, only: [:index, :create, :show, :update, :destroy]
It takes the following get request as a show action because show expects campaigns/:id, and it assumes 'viewAllCampaigns' is an id in this instance:
/campaigns/viewAllCampaigns
Your link_to should just be pointing to the following:
'/viewAllCampaigns'
Your route structure isn't really RESTful, but that's a separate topic.
I am using this as an example:
https://github.com/toshimaru/Rails-4-Twitter-Clone
The route file looks like:
Rails.application.routes.draw do
root 'static_pages#home'
resources :users do
member do
get :following, :followers
end
end
resources :sessions, only: [:new, :create, :destroy]
resources :tweets, only: [:index, :create, :destroy]
resources :relationships, only: [:create, :destroy]
get 'signup' => 'users#new'
get 'signin' => 'sessions#new'
delete 'signout' => 'sessions#destroy'
get 'about' => 'static_pages#about'
match '*path' => 'application#routing_error', via: :all
end
It appears that in some controllers there are comments mentioning which route it uses, however it's not specified in the route file. For instance:
# GET /users
def index
#users = User.all
end
# GET /users/1
def show
#tweet = current_user.tweets.build if signed_in?
#feed_items = #user.tweets.paginate(page: params[:page])
end
(in users_controller.rb)
My question is, how does rails app know that there is an endpoint here? I would like to know whether I can actually collect all the routes in one file?
What I am intending to do is, I would like to replace current routes.rb file with all routes.
Its specified in route file
When, we write
resources :users
It creates CRUD routes for specified resource namely index, new, create, show, edit, update, destroy routes for resource, here in this case resource is user.
You can see all routes for user by
rake routes | grep 'users'
and to list all routes in application
rake routes
resources :users has automatically created all RESTful routes for you, although you can limit it to only certain routes (as your example does with sessions, tweets, and relationships).
You can see all the routes from the console... in the root of your project do rake routes
See here for an explanation...
http://guides.rubyonrails.org/routing.html#listing-existing-routes
You can access the output of rake routes in your application....
output = `rake routes`
(note the use of backticks in the above)
I understand resource and path routes in rails 3 but I do not know is there any way to have both routes ? I try this routes but it not work for me, this is the routes:
resources :roles, only: [:index, :create, :show, :update]
get '/roles/:id' => 'roles#available_users'
How can we routes to use both routes ?
thankyou very much
Routes
What you're asking for cannot be done, as you'll be using the same "route" for different controller actions:
#config/routes.rb
resources :roles, only: [:index, :create, :show, :update] #-> domain.com/roles/:id - roles#show
If you then create another route for domain.com/roles/:id, Rails will just take the first which it finds in the routes file
--
The way to fix your issue is likely to be down to the following:
#config/routes.rb
resources :roles, except: [:edit, :destroy] do
get :available_users # -> domain.com/roles/:id/available_users
end
This will take you to the roles#available_users action, providing you with the ability to load the view you wish (to display the users for a particular role)
For a more defined explanation, I'd recommend checking out the nested_resources part of the Rails routing system
If I understand you correctly you want something like this:
resources :roles, only: [:index, :create, :update] do
get '/roles/:id' => 'roles#available_users'
end
Correct?
Just add an "do" behind the closing ] and an end after the custom routes.
Edit: Apparently I got wrong. ;) What you could do is:
resources :roles, only: [:index, :create, :show, :update] do
get '/roles/:id/available' => 'roles#available_users'
end
I have routes like this below. Is it possible if I have routes like this ?
#config/routes
resources :subscribers, only: [:index, :show]
namespace :admin do
resources :subscribers, only: [:new, :edit, :update, :create, :destroy]
end
I have tried to run rake routes and the result is
admin_subscribers POST /admin/subscribers(.:format) admin/subscribers#create
new_admin_subscriber GET /admin/subscribers/new(.:format) admin/subscribers#new
edit_admin_subscriber GET /admin/subscribers/:id/edit(.:format) admin/subscribers#edit
admin_subscriber PUT /admin/subscribers/:id(.:format) admin/subscribers#update
DELETE /admin/subscribers/:id(.:format) admin/subscribers#destroy
subscribers GET /subscribers(.:format) subscribers#index
subscriber GET /subscribers/:id(.:format) subscribers#show
the result was appropriate with my expectation, but when i run my RSpec i got errors
Routing Error
uninitialized constant Admin::SubscribersController
Try running rake routes for more information on available routes.
I added this code below in my Rspec Helper too
#spec/spec_helper.rb
Spork.each_run do
###
if /spork/i =~ $0 || RSpec.configuration.drb?
ActiveSupport::Dependencies.clear
end
###
end
But, if I fire my browser to htt**://l*alhost:3000/admin/subscribers/new, everything is fine.
Am I missing something ?
As stated in the docs
If you want to route /admin/subscribers to SubscribersController (without the Admin:: module prefix), you could use scope instead of namespace
#config/routes
resources :subscribers, only: [:index, :show]
scope "/admin" do
resources :subscribers, only: [:new, :edit, :update, :create, :destroy]
end
I don't think there's much need for you to namespace this under admin. You could just fill in all the actions on SubscribersController and set the permissions on create, update etc. appropriately.
