我尝试按照本文中使用的示例:http://bloginius.com/blog/2013/12/31/how-integrate-acts-as-taggable-on-with-jquery-token-input-with-rails-3/并将其应用于我的场景,但是在Rails 4.2中。如下:
<%= simple_form_for([:admin, @case_law]) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :title %>
<%= f.input :citations %>
<%= f.input :case_number %>
<%= f.input :facts, input_html: {rows: 15} %>
<%= f.input :holding, input_html: {rows: 15} %>
<%= f.input :jurisdiction, as: :country, priority: countries %>
<%= f.input :court, collection: court_listings %>
<%= f.input :judgment_date, as: :date_picker %>
<%= f.input :tag_list_tokens, data: {load: @case_law_tags} %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
case_laws.js.coffee
jQuery ->
$('#case_law_tag_list_tokens').tokenInput '/admin/case_laws/tags.json',
theme: 'facebook'
minChars: 2
allowCustomEntry: true
preventDuplicates: true
prePopulate: $('#case_law_tag_list_tokens').data('load')
LIB /扩展/ tag_extend.rb
module TagExtend
extend ActiveSupport::Concern
included do
scope :by_tag_name, -> name { where("name like ?", "%#{name}%") }
def self.token_input_tags
where(nil).map{ |t| {id: t.name, name: t.name} }
end
end
end
/initializers/acts_as_taggable_on.rb
ActsAsTaggableOn::Tag.send(:include, Intejus::TagExtend)
控制器/管理/ case_laws_controller.rb
class Admin::CaseLawsController < AdminController
before_action :find_tags, only: [:new, :create, :edit, :update]
....
def tags
tags = ActsAsTaggableOn::Tag.by_tag_name(params[:q]).token_input_tags
respond_to do |format|
format.json { render json: tags }
end
end
private
def find_tags
@case_law_tags = params[:id].present? ? CaseLaw.find(params[:id]).tags.token_input_tags : []
end
这是生成的html: &lt; \ div class =“form-group string optional case_law_tag_list_tokens”&gt;&lt; \ label class =“string optional control-label”for =“case_law_tag_list_tokens”&gt;标记列表标记&lt; \ ul class =“token-input-list -facebook“&gt;&lt; \ li class =”token-input-input-token-facebook“&gt;&lt; \ input type =”text“autocomplete =”off“autocapitalize =”off“id =”token-input- case_law_tag_list_tokens“style =”outline:none; width:209.993048667908px;“&gt;&lt; \ tester style =”position:absolute; top:-9999px; left:-9999px; width:auto; font-size:11.9999990463257px; font -family:Verdana,sans-serif; font-weight:400; letter-spacing:0px; white-space:nowrap;“&gt;&lt; \ input class =”string optional form-control“type =”text“name = “case_law [tag_list_tokens]”id =“case_law_tag_list_tokens”style =“display:none;”&gt;
我的第一期: 如果单击编辑页面链接,则不会加载标记字段,并显示常规文本字段。如果我刷新编辑页面,则会出现令牌字段。
第二期: 自动完成功能正常,标签已创建,但令牌字段不会预先填充。
答案 0 :(得分:1)
我意识到我应该使用文本字段:
<%= f.text_field :tag_list_tokens, data: {load: @case_law_tags} %>
而不是simple_form帮助器
<%= f.input :tag_list_tokens, data: {load @case_law_tags} %>
重装的问题与turbolinks有关。在链接后,Rails不会完全重新加载文档。它通过ajax加载页面之间的差异。我通过将代码修改为:
来修复此问题<强> case_laws.js.coffee 强>
