ruby-on-rails - Rails 4.1.1 w/pg_search - "PG::SyntaxError: ERROR: syntax error at or near "AS""Bug

转载作者：行者123 更新时间：2023-12-04 03:47:35

我从 RoR 4.0.4 更新到 4.1.1 以应用最新的安全补丁，但 pg_search 似乎坏了。

这是一个错误:

PG::SyntaxError: ERROR: syntax error at or near "AS" LINE 1: ...sh', ''' ' || unaccent('banner') || ' ''')), 0))) AS pg_sear...

我正在通过 ajax 进行搜索，但我认为这不是基于上述输出的问题。我也在使用 will_paginate，但我使用的分支应该可以解决 Rails 4.1.x 和 pg_search 以前的问题。

gem 'will_paginate', :git => 'https://github.com/nazgum/will_paginate.git' #until rails 4.1 will_paginate fixed

这是我执行搜索的代码模型:

  include PgSearch
  pg_search_scope :search, against: [:title, :body],
  using: {tsearch: {dictionary: "english"}},
  ignoring: :accents

  def self.text_search(query)
    if query.present?
      search(query)
    else
      scoped
    end
  end

在 RoR 版本碰撞之前一切都在工作 - 希望有人可以提供一些建议。

这是完整的堆栈跟踪:

最佳答案

@supports.count(:all)应该可以工作，@supports.count语法在 rails 4.1.1 中被弃用
