Rails 4 postgres全文搜索错误（范围）

Question

Ive been following the railscast on full text search with postgres but I keep getting the following error

undefined local variable or method `scoped' for #

Ive followed the railscast exactly. I have all the correct gems installed. (pg_search, pg). Here is my code

article controller (I'm also using acts_as_taggable here)

def index

   @articles = Article.text_search(params[:query]).page(params[:page]).per_page(3)

   if params[:tag]
      @articles = Article.tagged_with(params[:tag])
   else
      @articles = Article.all
   end
end

article model

def self.text_search(query)
  if query.present?
    where("name @@ :q or content @@ :q", q: query)
  else
   scoped
  end
end

And the form on Article/index

<%= form_tag articles_path, method: :get do %>
  <p>
    <%= text_field_tag :query, params[:query] %>
    <%= submit_tag "Search", name: nil %>
  </p>
<% end %>

The only difference I noted between the railscast code and mine is that hes using will_paginate but when I change the controller to

@articles = Article.text_search(params[:query])

it makes no difference.

Ive searched pretty much everywhere but to no avail.

Answer 1

scoped has been removed. Try all instead.
