如何显示个别微博的链接？ （铁轨上的ruby3）
我按照rails 3教程，我试图让它正常工作。
用户制作的所有微博都列在http://localhost:3000/users/username
UsersController
def show @user = User.find(params[:id]) @microposts = @user.microposts.paginate page: params[:page], :per_page => 15 end
每个微博都有一个ID
create_table "microposts", :force => true do |t| t.text "content" t.integer "user_id" t.datetime "created_at", :null => false t.datetime "updated_at", :null => false t.string "image" t.text "comment_content" end
如何设置它，以便http://localhost:3000/users/username/micropost_id （如果有效）等链接将导致只有那个微博的页面？
我希望显示器完全相同，只是在新页面上单独显示。
用户表
create_table "users", :force => true do |t| t.string "name" t.string "email" t.timestamp "created_at", :null => false t.timestamp "updated_at", :null => false t.string "password_digest" t.string "remember_token" end
我的配置路由
MyApp::Application.routes.draw do resources :authentications resources :microposts, :path => "posts" root to: 'static_pages#home' ActiveAdmin.routes(self) resources :users do member do get :following, :followers end end resources :sessions, only: [:new, :create, :destroy] resources :microposts, only: [:create, :destroy] resources :relationships, only: [:create, :destroy] resources :microposts do resources :postcomments end match '/signup', to: 'users#new' match '/signin', to: 'sessions#new' match '/signout', to: 'sessions#destroy', via: :delete match '/post', to: 'static_pages#post' match '/about', to: 'static_pages#about' match '/contact', to: 'static_pages#contact' match '/users/:username/:id', to: 'microposts#show', via: :get, as: :user_micropost end
您应该为routes.rb文件添加一个新路由，如下所示：
match '/users/:username/:id', to 'microposts#show', via: :get, as: :user_micropost
在显示用户微博的页面上，将链接添加为：
Whatever..
在微博控制器上，添加方法show：
def show @user = User.find_by_username(params[:username]) @post = Post.find_by_id(params[:id]) # handle any errors from the code above end
并创建下
app/views/microposts/show.html.erb
将显示微博的新页面。
我想在你的路线中你提到过这样的东西
resources :users do resources :microposts end
在这种情况下，您可以在/views/users/show.html.erb中创建一个链接，如下所示
<% @microposts.each do |post| <%= link_to truncate(post.content, :length => 10, :separator => '...'), user_micropost_path(@user, post) %> <% end %>
