使用act-as-taggable-on將標籤添加到不保存標籤的標籤

Question

我正在爲使用act-as-taggable-on創建引腳時用戶輸入時創建的「標籤」字段。我已經運行遷移並編輯了form_html.erb，pins_controller.rb和pin.rb.

標籤似乎並沒有保存，當我打開一篇文章進行編輯時，他們已經消失。

這裏是我的form_html.erb

<%= form_for @pin, html: { multipart: true } do |f| %> 
<% if @pin.errors.any? %> 
    <div id="error_explanation"> 
    <h2><%= pluralize(@pin.errors.count, "error") %> prohibited this pin from being saved:</h2> 

    <ul> 
    <% @pin.errors.full_messages.each do |message| %> 
    <li><%= message %></li> 
    <% end %> 
    </ul> 
    </div> 
<% end %> 

<div class="form-group"> 
    <%= f.label :image %> 
    <%= f.file_field :image, class: "form-control" %> 
    </div> 

    <div class="form-group"> 
<%= f.label :description %><br> 
<%= f.text_field :description, class: "form-control" %> 
    </div> 
    <div class="form-group"> 
<%= f.label :date %><br> 
<%= f.date_field :date, class: "form-control" %> 
    </div> 
    <div class="form-group"> 
    <%= f.label :tags, "Tags (separated by commas)"%><br /> 
    <%= f.text_field :tags_list%> 
</div> 
<div class="actions"> 
    <%= f.submit %> 
    </div> 
<% end %> 

我pins_controller.rb

class PinsController < ApplicationController 
    before_action :set_pin, only: [:show, :edit, :update, :destroy] 
    before_action :correct_user, only: [:edit, :update, :destroy] 
    before_action :authenticate_user!, except: [:index, :show] 



def index 
    @pins = Pin.all.order("created_at DESC").paginate(:page => params[:page], :per_page => 8) 
end 

    def show 
    end 

    def new 
    @pin = current_user.pins.build 

    end 

    def edit 
    end 

    def create 
    @pin = current_user.pins.build(pin_params) 
    if @pin.save 
     redirect_to @pin, notice: 'Pin was successfully created.' 
    else 
     render action: 'new' 
    end 
    end 

    def update 
    if @pin.update(pin_params) 
     redirect_to @pin, notice: 'Pin was successfully updated.' 
    else 
     render action: 'edit' 
    end 
    end 

    def destroy 
    @pin.destroy 
    redirect_to pins_url 
    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_pin 
     @pin = Pin.find(params[:id]) 
    end 

     def correct_user 
     @pin = current_user.pins.find_by(id: params[:id]) 
     redirect_to pins_path, notice: "Not authorized to edit this pin" if @pin.nil? 
    end 

    # Never trust parameters from the scary internet, only allow the white list through. 
    def pin_params 
     params.require(:pin).permit(:description, :image, :date, :tags) 
    end 
end 

我pin.rb

class Pin < ActiveRecord::Base 
    belongs_to :user 
    has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" } 
    validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png"] 
    acts_as_taggable 
end 

任何想法，爲什麼我似乎無法保存/輸入標籤？

我意識到我需要在pin.rb和pin_controller.rb中使用tag_list，並解決了這個問題！
