如何使用postgres_ext执行NOT查询

Question

Is it possible to perform a NOT type query with chained methods using postgres_ext? 是否可以使用postgres_ext对链接方法执行NOT类型查询？

rules = Rule.where.overlap(:tags => ["foo"])

Basically want the inverse of the above. 基本上要上面的反面。 Thanks! 谢谢！

Answer 1

In regular active record you can use .where.not as described in this article: https://robots.thoughtbot.com/activerecords-wherenot however looking through the source code of postgres_ext I don't know if it is defined in that library. 在常规活动记录中，您可以使用.where.not ，如本文中所述： https : .where.not ，但是查看postgres_ext的源代码，我不知道它是否在该库中定义。 You may be able to construct your query in a way that uses the native active record methods. 您可能可以使用本机活动记录方法来构造查询。
