标签没有保存或显示,为什么?

| 我正在使用行为上可标记的方式,并且很幸运,暂时没有尝试解决这个问题。由于某种原因,我无法让标签显示或保存在数据库中。我确实需要一些帮助,我在网上看了一下,而且文档是中级的或不友好的。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:
  <div class=\"field\"> 
    <%= f.label :tag_list %>
    <%= f.text_field :tag_list %>
  </div>
显示视图:
<p>
    <b>Tags:</b> 
    <%= @product.tag_list %>     
</p>
使用更新的工作代码进行编辑: 我正在使用Devise,只允许current_user(产品表中的user_id)执行诸如create,destroy,update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
产品负责人:
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
products / index.html.erb:
<td><%= product.tag_list %></td>
products / show.html.erb:
<p>
    <b>Tags:</b> 
    <%= @product.tag_list %>     
</p>
    
已邀请:
        尝试在您的视图中使用以下代码:
<p>
    <b>Tags:</b> 
    <%= @product.tags %>     
</p>
    
        我遇到了类似的情况。我尚未将:tag_list添加到我的events_controller中(我正在为我的青年组制作准系统的聚会聚会克隆)-
private
        def event_params
            params.require(:event).permit(:title, :text, :user_id, :event_start, :time_begin, :location, :address, **:tag_list**)
        end
end
除此之外,没有抛出任何其他错误,幸运的是我也想到了这一点。
