In my routes.rb I have
namespace :admin do
resources :clients do, only: [:index] do
resources :products, only: [:index, :new, :create]
end
resources :products, only: [:index]
end
Notice that I have two lines for resources :products. One is nested within resources :clients and the other as a top-level resource on :admin; each of these two has a different purpose in the application.
rake routes gives me:
admin_clients GET /admin/clients(.:format) admin/clients#index
admin_client_products GET /admin/clients/:client_id/products(.:format) admin/products#index
POST /admin/clients/:client_id/products(.:format) admin/products#create
new_admin_client_product GET /admin/clients/:client_id/products/new(.:format) admin/products#new
admin_products GET /admin/products(.:format) admin/products#index
I have a admin_client_products for the nested product#index resource. I also have admin_products for the top-level product#index resource. However, they point to the same controller action: admin/product#index.
Question: At this point, I need rails to deduce that these are two different actions. Using rails conventions, is there a way to tell rails that these two resources should have different controller actions i.e. one that should hit admin/products#index and the other should hit admin/clients/products#index?
The nested route should hit this:
class Admin::Clients::ProductsController < Admin::BaseController
def index; end
end
The top-level route should hit this:
class Admin::ProductsController < Admin::BaseController
def index; end
end
Definitely you can!
Here you need to customize your resourceful route by explicitly specifying a controller to use for the resource. The :controller option will let you do that.
So, in your case, specifying the controller as clients/products for the admin_clients_products resource would work in your desired way.
namespace :admin do
resources :clients, only: [:index] do
resources :products, only: [:index, :new, :create], controller: 'clients/products'
end # ------------------------------
resources :products, only: [:index]
end
rails routes will now give you what you want:
admin_client_products GET /admin/clients/:client_id/products(.:format) admin/clients/products#index
POST /admin/clients/:client_id/products(.:format) admin/clients/products#create
new_admin_client_product GET /admin/clients/:client_id/products/new(.:format) admin/clients/products#new
admin_clients GET /admin/clients(.:format) admin/clients#index
admin_products GET /admin/products(.:format) admin/products#index
=========================
Extra bits:
If you want to omit the /admin portion from the url (I mean, if your application's routing design permits to), then you could use: scope module: 'admin' do...end like the following:
scope module: 'admin' do
resources :clients, only: [:index] do
resources :products, only: [:index, :new, :create], controller: 'clients/products'
end
resources :products, only: [:index]
end
and suddenly your routes will start looking awesome :)
client_products GET /clients/:client_id/products(.:format) admin/clients/products#index
POST /clients/:client_id/products(.:format) admin/clients/products#create
new_client_product GET /clients/:client_id/products/new(.:format) admin/clients/products#new
clients GET /clients(.:format) admin/clients#index
products GET /products(.:format) admin/products#index

In my routes.rb file, I have the following resources
resources :classrooms, only: [:index, :new, :create] do
resources :students, only: [:index, :edit, :update], controller: 'students' do
get :honor
end
end
My honor route becomes /classrooms/:classroom_id/students/:students_id/honor(.:format)
but I want to replace student_id to id so that I can easily use it in the students controllers.
Ideal route is /classrooms/:classroom_id/students/:id/honor(.:format)
You can do that specifying it's a member route. this way
get :honor, on: :member
or
member do
get :honor
end
I have a rails nested resource in my routing.
i.e
resources :users do
resources :accounts
end
resources :accounts
The listing operations of course will be:
GET /users
GET /users/:user_id/accounts
I want to get rid of the /users route but retain the /users/:id/accounts route.
Any idea how I can go about this? Thanks
Using except: [:index] not will restrict both routes. Thats a nonsenical claim that can easily be refuted by just running rails routes. None of the options for resources "trickle down" to nested calls.
resources :users, only: [] do
resources :accounts, only: :index
end
only: [] skips generation of all the "user" routes.
This will generate the routes:
Prefix Verb URI Pattern Controller#Action
user_accounts GET /users/:user_id/accounts(.:format) accounts#index
# ...
Note that the param key is :user_id and not :id. If you REALLY want to break the conventions you would need to do:
# don't do this - its stupid
scope '/users/:id', as: :user do
resources :accounts, only: :index
end
let set only: [] then rails routes will generate /users/:id/accounts as you want
resources :users, only: [] do
resources :accounts # , only: [:index] if you just only keep users/:id/accounts
end
# if you only want to get rid of GET /users
resources :users, except: [:index]
# if you mean you want to get rid all of /users routes (not just only GET /users) then comment above line
This is what scope is for
scope :users do
resources :accounts
end
Rails guides on routing
Or you can use these same two ways, use namespace with scope:
namespace :users do
scope ':user_id' do
resources :accounts
end
end
Use just only scope:
scope ':users/:user_id' do
resources :accounts
end
I'm actually having trouble finding the documentation for this so if you have a link handy that would be really appreciated too.
So I have:
resources :users do
resources :posts, only: [:index, :create, :show]
end
I wanted to access the index action of posts through a named route. I tried this: <%= link_to 'User Posts', user_posts_path %> but it said it was missing user_id. Any ideas?
When using the nested resource routes, you would need to provide the reference id of the parent resource. In your case resource user. You could do: user_posts_path(user). The route generated would be something like: /users/1/posts where 1 is the :user_id or if you would rather want a route like: /users/posts you should do:
resources :users do
collection do
resources :posts
end
end
Find full routing documentation here
it's asking for user_id because you're defining :users as a resource, change it for a namespace instead:
namespace :users do
resources :posts, only: [:index, :create, :show]
end
Im trying to create API endpoints from my Post model . It should be able to read, update, delete and create posts.
But a post needs to be assosiated to a Topic in order for it to be created so i nested it under topics. Here are my routes
namespace :api do
namespace :v1 do
resources :users, only: [:index, :show, :create, :update]
resources :posts, only: [:show, :update, :destroy]
resources :topics, except: [:edit, :new] do
resources :posts, only: [:create]
end
end
end
api_v1_post GET /api/v1/posts/:id(.:format) api/v1/posts#show
PATCH /api/v1/posts/:id(.:format) api/v1/posts#update
PUT /api/v1/posts/:id(.:format) api/v1/posts#update
DELETE /api/v1/posts/:id(.:format) api/v1/posts#destroy
api_v1_topic_posts POST /api/v1/topics/:topic_id/posts(.:format) api/v1/posts#create
api_v1_topics GET /api/v1/topics(.:format) api/v1/topics#index
POST /api/v1/topics(.:format) api/v1/topics#create
api_v1_topic GET /api/v1/topics/:id(.:format) api/v1/topics#show
PATCH /api/v1/topics/:id(.:format) api/v1/topics#update
PUT /api/v1/topics/:id(.:format) api/v1/topics#update
DELETE /api/v1/topics/:id(.:format) api/v1/topics#destroy
my issue is im getting a "no routes match" error when i run my Rspec
I think the issue is with the relationship.
Please add the relationship between Topic and Post and then try.
class Topic < ActiveRecord::Base
has_many :posts
end
class Post < ActiveRecord::Base
belongs_to :topic
end
If the route you are trying to create is POST api/v1/topics/:topic_id/create_post going to TopicsController than you would want the nesting to look like this instead:
resources :topics, except: [:edit, :new] do
post 'create_post' => 'topics#create_post'
end
Try this out for creating your routes if you haven't had success yet. It should provide the output that you want.
resources :topics, except: [:edit, :new] do
collection do
post 'create_post'
end
end
I have to models User and Blog. Their respective urls are:
test.com/u/user_name # User
test.com/blogs # Blog
I'm trying to achieve that the blogs are nested to the user which created it. E.g. test.com/u/user_name/blogs and for an article test.com/u/user_name/blogs/article_name.
But the index for all blogs should respond to: test.com/blogs.
right now my routes are like this:
resources :users do
resources :blogs, except: [:index]
end
resources :blogs, only: [:index]
Which doesn't work.. What am i missing?
Routes
#config/routes.rb
resources :blogs, only: :index #-> domain.com/blogs -> blogs#index
resources :users, path: "u" do #-> domain.com/u/:id
resources :blogs #-> domain.com/u/:user_id/blogs/:id
end
You'll want to look up about the path argument for your routes
As a rule of thumb, you'll want to include any "non conventional" paths at the bottom of the routes file. As the routes are determined from the top to bottom, if you're capturing obscure paths near the top of the file, you'll end up causing conflict with your other routes
