Question

我使用form_tag创建了一个简单的搜索表单，并且我有一个gem will_paginate。当我尝试搜索某些内容时，会出现错误：undefined method 'total_pages' for #<Post::ActiveRecord_Relation:0x007f91ca043130>

这是我的post_controller.rb的一部分：

 def index
     @posts = unless params[:search].nil?
       Post.search(params[:search])
     else
       @posts = Post.paginate(page: params[:page], :per_page => 5)
    end
 end

模型post.rb：

class Post < ActiveRecord::Base
  belongs_to :user
  default_scope -> {order('created_at DESC')}
  validates :user, presence: true
  validates_presence_of :title, :body, :tags
  validates :title, length: { in: 5..100}
  validates :tags, uniqueness: true
  validates :user_id, presence: true

  def self.search(search)
    where("title LIKE ? OR body LIKE ?", "%#{search}%", "%#{search}%")
  end

end

并查看posts_index：

<%= form_tag(posts_path, method: 'GET') do%>
    <%= text_field_tag :search, params[:search], class: 'input-sm',placeholder: 'Search for...'%>
    <%= image_submit_tag('search.png', class: 'picture_size')%>
<% end %>

<%= will_paginate %>

<% @posts.each do |post| %>
    <p> <%= post.title %> </p>
    <p><%= post.body %> </p>
    <p> <%= post.tags %> </p>
<% end %>

<% will_paginate %>

它仍然可以正常工作，除非我尝试搜索某些东西。只有在搜索后才收到错误。我该如何解决这个问题？
