如何使用ps_search gem for Rails 5仅搜索批准的帖子

Question

我正在对邮政和网站表格进行多次搜索。我有is_approved布尔值的所有记录。当前，pg_search查找所有帖子，但是我只需要显示具有is_approved == true的帖子。

我知道我可以在is_approved字段中以“ if”状态签入循环，但听起来效率不高。我相信pg_search将有更好的限制方法。

干杯

Answer 1

尝试在所需模型中使用default_scope。例如，

class Post < ApplicationRecord
  include PgSearch
  default_scope { where(is_approved: true)}
  multisearchable :against => :title
