标签不保存或显示，为什么？(Tags not saving or showing, why?)

我现在正在使用行为标签 -并且没有任何运气试图找出一段时间。由于某种原因，我无法让我的标签出现或保存在数据库中。我真的需要一些帮助，我在网上查看，文档是中间或不是新手友好的。这是我的代码：

设计用户模型：

class User < ActiveRecord::Base has_many :products, :dependent => :destroy acts_as_tagger end

产品型号：

class Product < ActiveRecord::Base attr_accessible :name, :date, :price, :tag_list acts_as_taggable_on :tags belongs_to :user end

形成：

显示视图：

Tags: <%= @product.tag_list %>

编辑更新和工作代码：

我正在使用Devise，并且只让current_user （产品表中的user_id）执行诸如创建，销毁，更新标签等操作。

用户模型：

class User < ActiveRecord::Base has_many :products, :dependent => :destroy acts_as_tagger end

产品型号：

class Product < ActiveRecord::Base attr_accessible :name, :date, :price, :tag_list, :longitude, :latitude acts_as_taggable_on :tags end

产品控制器：

class ProductsController < ApplicationController before_filter :authenticate_user! def index @products = Product.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @products } end end def show @product = Product.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @product } end end def new @product = Product.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @product } end end def edit @product = current_user.products.find(params[:id]) @product.user = current_user end def create @product = current_user.products.build(params[:product]) @product.user = current_user respond_to do |format| if @product.save format.html { redirect_to(@product, :notice => 'Product was successfully created.') } format.xml { render :xml => @product, :status => :created, :location => @product } else format.html { render :action => "new" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end def update @product = current_user.products.find(params[:id]) @product.user = current_user respond_to do |format| if @product.update_attributes(params[:product]) format.html { redirect_to(@product, :notice => 'Product was successfully updated.') } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end def destroy @product = current_user.products.find(params[:id]) @product.destroy respond_to do |format| format.html { redirect_to(products_url) } format.xml { head :ok } end end end

Tags: <%= @product.tag_list %>

I am using acts-as-taggable-on and without any luck been trying to figure this out for awhile now. For some reason i cannot get my tags to show up or save inside of the database.I really need some help, i looked online and the documentation is intermediate or not newbie friendly. Here is my code:

Devise User Model:

class User < ActiveRecord::Base has_many :products, :dependent => :destroy acts_as_tagger end

Products Model:

class Product < ActiveRecord::Base attr_accessible :name, :date, :price, :tag_list acts_as_taggable_on :tags belongs_to :user end

Form:

Show View:

Tags: <%= @product.tag_list %>

EDIT WITH UPDATED AND WORKING CODE:

I am using Devise and letting only the current_user (user_id in products table) do actions such as create,destroy,update tags,etc.

User Model:

class User < ActiveRecord::Base has_many :products, :dependent => :destroy acts_as_tagger end

Product Model:

class Product < ActiveRecord::Base attr_accessible :name, :date, :price, :tag_list, :longitude, :latitude acts_as_taggable_on :tags end

Products Controller:

class ProductsController < ApplicationController before_filter :authenticate_user! def index @products = Product.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @products } end end def show @product = Product.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @product } end end def new @product = Product.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @product } end end def edit @product = current_user.products.find(params[:id]) @product.user = current_user end def create @product = current_user.products.build(params[:product]) @product.user = current_user respond_to do |format| if @product.save format.html { redirect_to(@product, :notice => 'Product was successfully created.') } format.xml { render :xml => @product, :status => :created, :location => @product } else format.html { render :action => "new" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end def update @product = current_user.products.find(params[:id]) @product.user = current_user respond_to do |format| if @product.update_attributes(params[:product]) format.html { redirect_to(@product, :notice => 'Product was successfully updated.') } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end def destroy @product = current_user.products.find(params[:id]) @product.destroy respond_to do |format| format.html { redirect_to(products_url) } format.xml { head :ok } end end end
