您如何将搜索添加到布局中，以便它可以通过网站的每个页面搜索帖子？比如在stackoverflow上。

教程展示了将搜索方法添加到 PostsController 的 index 操作，然后在 views/post/index.html.erb 中添加表单和结果块。

我一直在尝试在 application.html.erb 中创建一个表单，该表单将获取请求发送到帖子控制器的搜索操作。我似乎无法正确解决，有人可以帮助解释我哪里出错了吗？

目前我在访问我的主页时收到此错误：

页面中的名称错误#home

未定义的局部变量或方法“search_posts_path”

帖子控制器

   def search
     if params[:q]
       query = params[:q]
       @search = Post.search do
         keywords query
       end
       @posts = @search.results
     end
    end

后模型

 searchable do
       text :title, :default_boost => 2
       text :content
  end

路线.rb

  match 'auth/:provider/callback' => 'authentications#create'
  resources :authentications

  devise_for :users, :controllers => {:registrations => 'registrations'}




  resources :posts do
      member do
      get :likers, :search
      end
  end  

  resources :relationships, :only => [:create, :destroy]
  resources :appreciations, :only => [:create, :destroy]

  root :to => "pages#home"

 match '/contact', :to => 'pages#contact'
 match '/about',   :to => 'pages#about'
 match '/help',    :to => 'pages#help'
 match '/blog',    :to => 'pages#blog'


  resources :users do
     member do
     get :following, :followers, :likes
     end
     resources :collections
  end

视图/布局/application.html.erb

<%= form_tag search_posts_path, :method => :get do %>
<p>
<%= text_field_tag :q, params[:q] %> <%= submit_tag "Search!" %>
</p>
<% end %>

页面控制器

 def home
    @title = "Home"
    if user_signed_in?
      @user = current_user
      @post = current_user.posts.build
      @feed_items = current_user.feed.paginate(:per_page => "10", :page => params[:page])
    else
     #render :layout => 'special_layout' 
    end
  end

这是一个 Ruby on Rails 路由问题。

该member路线用于对单个记录进行操作。所以你正在定义search_post_path(@post)哪个将路由到类似的东西/posts/1/search

你想要的是一条collection路线。

resources :posts do
  member do
    get :likers
  end
  collection do
    get :search
  end
end

这将创建您所期望的search_posts_path方法和路由。/posts/search
