Question

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:

  <div class="field"> 
    <%= f.label :tag_list %>
    <%= f.text_field :tag_list %>
  </div>

Show View:

<p>
    <b>Tags:</b> 
    <%= @product.tag_list %>     
</p>

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

products/index.html.erb:

<td><%= product.tag_list %></td>

products/show.html.erb:

<p>
    <b>Tags:</b> 
    <%= @product.tag_list %>     
</p>

Answer 1

Try using this code in your view:

<p>
    <b>Tags:</b> 
    <%= @product.tags %>     
</p>
