我正在尝试让令牌字段在我的应用程序上工作。
我完全按照这个视频：http ://railscasts.com/episodes/258-token-fields
项目模型
class Project < ActiveRecord::Base
attr_accessible :edited_first_name, :edited_last_name, :first_name, :last_name, :business_div, :client, :customer_benifits, :edited_date, :end_date, :entry_date, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech , :technols, :technol_tokens
has_many :projecttechnols
has_many :technols, :through => :projecttechnols
attr_reader :technol_tokens
def technol_tokens=(ids)
self.technol_ids = ids.split(",")
end
accepts_nested_attributes_for(:technols)
技术控制器：
def index
@technols = Technol.where("tech like ?", "%#{params[:q]}%")
respond_to do |format|
format.html # index.html.erb
format.json { render :json => @technols.map(&:attributes) }
end
end

application.js编辑：
$(function() {
$("#project_technol_tokens").tokenInput("/technols.json", {
crossDomain: false,
prePopulate: $("#project_technol_tokens").data("pre"),
theme: "facebook"
});
});
$(function() {
$("#project_start_date").datepicker({dateFormat: 'dd-mm-yy'});
});
$(function() {
$("#project_end_date").datepicker({dateFormat: 'dd-mm-yy'});
});
jQuery(function(){
jQuery('#start_date_A').datepicker({dateFormat: "dd-mm-yy"});
});
jQuery(function(){
jQuery('#start_date_B').datepicker({dateFormat: "dd-mm-yy"});
});
在我的新页面上，我有一个可以工作的 jquery datepicker 文本框。我不明白为什么同一页面上的令牌字段不起作用。
我已经按照视频大约 3 次来确保它仍然无法正常工作。唯一的区别是我将我的 javascripts 和样式表放在 assets 文件夹中，在视频中它放在 public 文件夹中。任何人都可以帮忙吗？谢谢。
