嗨我正在学习Rails我需要了解routes.rb文件我已阅读http://guides.rubyonrails.org/routing.html，这非常有用，无论如何。
我正在尝试
<% @posts.each do |post| %>
<div id="entrada">
<h2><%= link_to post.title, post %></h2>
<% if post.postimage.present? %>
<%= link_to (image_tag post.postimage.url(:thumb)), (post_path(post)) %>
<% else %>
<%= link_to (image_tag ("espanol/playersample.png")), (post_path(post)) %>
<% end %>
<p><%= simple_format h(post.text) %></p>
<table>
<tr>
<td><%= link_to t('generales.ver'), post %></td>
<td><%= link_to t('generales.editar'), edit_post_path(post) %></td>
<td><%= link_to t('generales.delete'), post_path(post),
method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
</table>
</div>
<% end %>
这个问题。是<%= link_to post.title, post %>这会产生类似
domain.com/posts/?id
它还可以，但我是管理员，所以它应该是domain.com/admin/posts/?id
我几乎尝试了所有事情，比如做<%= link_to post.title, admin_post_path %>
但这有一个错误的语法错误，对你来说可能很明显，我需要理解为什么。

我的routes.rb文件是
Consult::Application.routes.draw do
devise_for :users, :controllers => { :registrations => "registrations" }
scope "/admin" do
resources :users, :controller => 'admin/users'
resources :posts, :controller => 'admin/posts'
end
resources :players
resources :player_steps
resources :coach_steps
resources :candidates
resource :payment_notifications, :only => :show
#match 'candidates' => 'candidates#index'
#resources :posts
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'
match '*a', :to => 'errors#routing'
# 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)'

如何将link_to设置为正确的domain.com/admin/posts/?id
答案 0 :(得分：1)
您只想使用post_path
背后的原因是来自rake routes：
post GET /admin/posts/:id(.:format) admin/posts#show
阅读方式如下。
post是路径的名称，IE，您可以使用post_path
GET是访问路线的方法。
/admin/posts/:id(.:format)是您将在浏览器中看到的网址。 :id将替换为整数，(.:format)是可选格式。 IE json，xml等
admin/posts#show分别是要使用的文件夹，控制器和方法。
答案 1 :(得分：1)
在路线文件上，我会替换以下内容：
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'
由此：
namespace :admin do
resources :posts
end
然后链接应该像这样工作：
<%= link_to post.title, admin_post(post) %>
如果您的Post模型已在app / models / admin / Post.rb等管理文件夹中创建，则使用＆lt;％= link_to post.title，post％＆gt;应该按你的意愿工作
