How do you create links in Rails using link.to - ruby-on-rails

Question

Hi im doing a kind of blog to learn Rails, using the Getting started tutorials like these
http://guides.rubyonrails.org/getting_started.html
http://guides.rubyonrails.org/routing.html
I have manage to do the posts sections and i also do a admin/posts section, this is the problem now..
Ths system is "conflicting" and admin goes to domain.com/posts instead of admin/posts.
I think the problem is the way i build the links..
In the tutorial to link a item yo do
<h2><%= link_to post.title, post %></h2>
I have tried
<h2><%= link_to post.title, admin_post_path %></h2>
And similars but i get
undefined local variable or method `admin_post_path' for #<#<Class:0x007fe3e990ef28>:0x007fe3e6e3b508>
How does this works i mean i have done rake routes and i see there the routes, but i cant use them

Routes.rb
Consult::Application.routes.draw do

scope "/admin" do
resources :users, :controller => 'admin/users'

end
resources :players
resources :player_steps
resources :coach_steps
resources :candidates
resource :payment_notifications, :only => :show

# The priority is based upon order of creation:
# first created -> highest priority.
# Sample of regular route:
# match 'products/:id' => 'catalog#view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Sample resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Sample resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Sample resource route with more complex sub-resources
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', :on => :collection
# end
# end
# Sample resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
#root :to => "devise/sessions#new"
get 'user_type', to: 'home#user_type', as: :choose
devise_scope :user do
root :to => "devise/sessions#new"
end
# See how all your routes lay out with "rake routes"
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
# match ':controller(/:action(/:id))(.:format)'

Answer 1

Try using namespace, as opposed to the scope, as the namespace is much better for nesting. your routes file should look something like this.
namespace :admin do
resources :users
resources :posts
end
resources :players
resources :player_steps
resources :coach_steps
resources :candidates
resource :payment_notifications, :only => :show
#match 'candidates' => 'candidates#index'
resources :posts
you can remove
get '/posts/:id', to: 'posts#show', as: 'post'
get '/posts/', to: 'posts#index', as: 'posts'
get '/admin/posts/', to: 'admin/posts#index', as: 'admin_posts_path'
post '/admin/posts/', to: 'admin/posts#index', as: 'admin_posts_path'
get '/admin/posts/:id', to: 'admin/posts#show', as: 'admin_post_path'
get '/admin/posts/new', to: 'admin/posts#new', as: 'new_admin_post_path'
as the namespace and the resources handle their generation
full routes file should be
Consult::Application.routes.draw do
devise_for :users, :controllers => { :registrations => "registrations" }
namespace :admin do
resources :users
resources :posts
end
resources :players
resources :player_steps
resources :coach_steps
resources :candidates
resources :posts
resource :payment_notifications, :only => :show
get 'user_type', to: 'home#user_type', as: :choose
devise_scope :user do
root :to => "devise/sessions#new"
end
end
