如何显示单个微博的链接?(ruby on rails 3) [英] how to display a link to individual microposts? (ruby on rails 3)

问题描述

我遵循了 rails 3 教程，我正在努力使其正常工作.

I followed a rails 3 tutorial and I'm trying to get this to work correctly.

用户发布的所有微博都列在http://localhost:3000/users/username

All microposts that a user make is listed in http://localhost:3000/users/username

用户控制器

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

我如何设置它以便诸如 http://localhost:3000/users/username/micropost_id(如果有效)之类的链接将指向只有该​​微博的页面?

How can I set it up so that a link such as http://localhost:3000/users/username/micropost_id (if valid) will lead to page that has just that micropost?

除了在新页面上单独显示之外，我希望显示完全相同.

I want the display to be exactly the same except show up individually on a new page.

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

推荐答案

你应该在你的 routes.rb 文件中添加一个新的路由，如下所示:

You should add a new route to your routes.rb file like the following:

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:

and on the page that shows user's microposts, add the link as:

<a href="<%= user_micropost_path(username: @user.username, id: micropost.id) %>">Whatever..</a>

在 microposts 控制器上，添加 show 方法:

On the microposts controller, add the method 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

并在下面创建

app/views/microposts/show.html.erb

将显示微博的新页面.
