acts as-taggable-on(2.2.2) will_paginate(3.0.2) rails(3.0.3) ruby 1.8.7 tagged_with方法未定义

Question

我正在使用以下指定的gem

acts-as-taggable-on(2.2.2)
will_paginate(3.0.2)
rails(3.0.3) 
ruby 1.8.7 

我尝试使用tagged_with未定义的方法tagged_with代码

@search = Product.tagged_with(params[:search][:tag_name]).paginate(:per_page => 15, :page => params[:page])

输出：

NoMethodError (undefined method `tagged_with' for #<Class:0xb51a0f08>):

然后我尝试了find_tagged_with未定义的方法分页代码

@search = Product.find_tagged_with(params[:search][:tag_name]).paginate(:per_page => 15, :page => params[:page])

输出

NoMethodError (undefined method `paginate' for #<Array:0xb512f790>):


class Product < ActiveRecord::Base
  attr_accessible :tag_list
  acts_as_taggable
end

请指导我如何使Will_paginate与阵列/acts-as-taggable-on一起工作。提前谢谢..

Answer 1

将此行添加到您在数组上使用will_paginate的文件中。

require 'will_paginate/array' 

如果要全局启用，请将其添加到application.rb的末尾
