Question

使用acts-as-taggable-on和rails4-autocomplete自动填充代码。这是我的代码。

的routes.rb

  get 'tags/:tag', to: 'posts#index', as: :tag

  resources :posts do
    get :autocomplete_tag_name, :on => :collection
  end

posts_controller.rb

autocomplete :tag, :name

的application.js

//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require autocomplete-rails

_form.html.haml

= f.input :tag_list, :url => autocomplete_tag_name_posts_path, :as => :autocomplete

当我开始输入时，我可以看到对服务器的请求，但返回（404）Not Found as

http://localhost:3000/posts/autocomplete_tag_name?term=rails

Firefox DevTool网络

ActiveRecord::RecordNotFound at /posts/autocomplete_tag_name
============================================================

> Couldn't find Post with 'id'=autocomplete_tag_name

app/controllers/posts_controller.rb, line 133
---------------------------------------------

``` ruby
  128     end
  129   
  130     private
  131       # Use callbacks to share common setup or constraints between actions.
  132       def set_post
> 133         @post = Post.find(params[:id])
  134       end
  135   
  136       # Never trust parameters from the scary internet, only allow the white list through.
  137       def post_params
  138         params.require(:post).permit(:title, :body, :image, :tag_list)

找不到标识为autocomplete_tag_name的帖子，它不应该是这样的。

如果我将请求硬编码为

http://localhost:3000/tags/autocomplete_tag_name?term=rails

它返回200（ok）

Answer 1

我认为这是路由错误。查看硬编码链接，它位于localhost:3000/tags/，但您的404错误正在寻找localhost:3000/posts/。看看这篇文章的答案，它的Rails3，但它可能有一些用处：How to add tagging with autocomplete to an existing model in Rails?

Rails：无法＃39;使用＆＃39;＆＃39; = autocomplete tag_name查找帖子
