问题描述

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 problemand 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 1and 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 2in view , in place of <%= f.autocomplete_field :title_cont,used 1 ) :title_start no changes2) :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 3i'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 4tried 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 5changed 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 6As 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
