Friendly_ID Ruby on Rails [英] Friendly_ID Ruby on Rails

问题描述

即使使用了 slug，URL 仍然显示 id 而不是标题.代码如下

The URL still shows the id and not the title even after using slug. Code as follows

index.html.erb

<title>Blog!</title>
<h1>List of the Posts</h1>
<% @posts.each do |post| %>
  <%= link_to post.title,:id => post.slug%>
  <p><%= post.content %></p>
  <%= link_to "Edit",edit_post_path(post) %> |
  <%= link_to "Delete",post,:confirm=>"Are you sure ?",:method=>:delete %>
  <hr />
<% end %>
<p><%= link_to "Add a New Post",new_post_path %></p>

posts_controller.rb

class PostsController < ApplicationController
  def index
    @posts=Post.all
  end

  def show
    @posts=Post.find(params[:id])
  end

结束

发布模型

  extend FriendlyId
  friendly_id :title,use: :slugged

  def should_generate_new_friendly_id?
    new_record
  end

routes.rb

Blog::Application.routes.draw do
  get "blog/posts"
  resources :posts
end

我希望链接是localhost:8080/posts/this+is+the+title"而不是localhost:8080/posts/2"

I would want the link to be 'localhost:8080/posts/this+is+the+title' and not 'localhost:8080/posts/2'

推荐答案

我也遇到了这个问题.当我链接到我的资源的显示操作时，我会在 url 中获取 id 而不是我的 slug.虽然我可以输入 slugged url 并且它也可以正常工作(我只是无法链接到 slugged url).事实证明，我必须使用命名的路由助手作为friendly_id 来显示 url 中的 slug(我使用的是老式的 controller: 'posts', action: 'show', id: post.id 在我的 link_to 助手中).在你的情况下，我会尝试改变:

I was having trouble with this issue too. When I linked to the show action of my resource, I would get the id in the url instead of my slug. Although I could type in the slugged url and it would also work fine (I just couldn't link to the slugged url). It turns out that I had to use named route helpers for friendly_id to display the slug in the url (I was using the old-school controller: 'posts', action: 'show', id: post.id in my link_to helper). In your case, I would try changing:

<%= link_to post.title, :id => post.slug %>

到

<%= link_to post.title, post_path(post) %>

此外，friendly_id 5.0 版要求您将控制器中的 Model.find 更改为 Model.friendly.find(除非您明确覆盖它config/initializers/friendly_id.rb.由于这是一个较旧的帖子，它可能不适用于您，但我想我还是会添加它.尝试更改:

Also, friendly_id version 5.0 requires that you change Model.find to Model.friendly.find in your controller (unless you explicitly override it config/initializers/friendly_id.rb. Since this is an older post, it might not apply to you, but I thought I'd add it anyway. Try changing:

def show
  @post = Post.find(params[:id])
end

到

def show
  @post = Post.friendly.find(params[:id])
end
