美好的一天. 我遇到了一个控制器，该控制器使用ransack按标题查找文章. 我需要用于查找信息的字段以使用自动完成功能. 目前它可以，但是没有自动完成功能，您能帮我解决这个问题吗 和gem https://github.com/crowdint/rails3-jquery-autocomplete-app?

Good day. I hame a controller that uses ransack to find articles by their title. I need field that's used for finding info to use autocomplete. Currently it finds alright, but no autocomplete, could you assist me in that problem and gem https://github.com/crowdint/rails3-jquery-autocomplete-app?

宝石文件

 gem "ransack"
    gem 'rails3-jquery-autocomplete'
    gem 'nifty-generators'
    gem 'jquery-rails', '~> 2.0'

视图中:

<%= search_form_for @q do |f| %>
  <%= f.label t('.find') %>
  <%= f.autocomplete_field :title_cont,
    articles_autocomplete_article_title_path, :size => 15 %><br />
  <%= f.submit :value=>'Search', :class=>'fl_right' %>
<% end %>

布局负责人:

 <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>
      <%= javascript_include_tag '/javascripts/jquery-ui-1.8.23.custom.min.js',
      '/javascripts/autocomplete-rails.js', '/javascripts/rails.js'  %>
    <%= stylesheet_link_tag '/stylesheets/ui-lightness/jquery-ui-1.8.23.custom.css' %>

控制器

class ArticlesController < ApplicationController
  autocomplete :article, :title

更新1 和routes.rb

UPDATE 1 and routes.rb

get 'articles/autocomplete_article_title'

更新2 在视图中，代替<%= f.autocomplete_field :title_cont, 用过的 1):title_start没有变化 2):articles_article_title_start等导致错误.

UPDATE 2 in view , in place of <%= f.autocomplete_field :title_cont, used 1 ) :title_start no changes 2) :articles_article_title_start and so on lead to errors.

更新3 我已经编辑了routes.rb.将"articles/autocomplete_article_title"移到了区域设置变量的范围内，现在可以正常工作了. ..出现了autocomplete下拉列表...但为空:(必须立即修复该问题.

UPDATE 3 i've edited routes.rb. moved get 'articles/autocomplete_article_title' into scope of locale variable, now it kind of works... autocomplete drop down list appears... but empty :( have to fix that one now.

更新4 尝试使用 http://railscasts.com/episodes/102-auto-complete-association .但这是用于较旧版本的rails ...等等

UPDATE 4 tried to use http://railscasts.com/episodes/102-auto-complete-association. but it's for older version of rails... and so on

更新5 改变了routes.rb

UPDATE 5 changed in routes.rb

  resources :articles do
    get 'autocomplete_article_title'
  end

还没有运气.

更新6 据我了解，当前的问题是:洗劫&自动完成功能使用一个字段. 适用于搜查autocomplete_field类型的字段.但是我不知道如何通过自动完成的ransack工作使字段名称可接受.你能帮忙吗?

UPDATE 6 As far as i understand current problem is: ransack & autocomplete use one field. It's suitable for ransack that field of autocomplete_field type. but i don't know how to make field name acceptable by ransack work with autocomplete. Could you help?

更新7 因此，鉴于

   f.text_field :title_start,
      "data-autocomplete" => articles_autocomplete_article_title_path,
      :size => 15

在routes.rb中

in routes.rb

scope '(:locale)' do
  resources :users
  resources :news
  resources :articles do

  end
  get 'articles/autocomplete_article_title'
  get "news/index" , as: 'news'

# match "/news*tail" => 'news#index'
  root :to => 'News#index', as: 'news'
end

推荐答案

代替

f.autocomplete_field :title_cont,
    articles_autocomplete_article_title_path, :size => 15 

尝试

f.text_field :title_cont, "data-autocomplete" => articles_autocomplete_article_title_path

在我的项目中，我使用了meta_search和simple_form，就像

In my project i used meta_search and simple_form and it was like

f.input :country_name_equals, url: autocomplete_country_name_path, :as => :autocomplete
