我正在使用acts-as-taggable-on,并且没有任何运气一直试图弄清楚这一点。出于某种原因,我无法让我的标签显示或保存在数据库中。我真的需要一些帮助,我在网上查看了文档,文档是中级的,或者对新手不友好。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
形式:
<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>
使用更新和工作代码进行编辑:
我正在使用设计并只让current_user(产品表中的 user_id)执行创建、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
产品/index.html.erb:
<td><%= product.tag_list %></td>
产品/show.html.erb:
<p>
<b>Tags:</b>
<%= @product.tag_list %>
</p>
