Is there a way to invert an ActiveRecord::Relation query?

Question

Let\'s say we have the following:

irb> Post.where(:hidden => true).to_sql
=> \"SELECT `posts`.* FROM `posts` WHERE posts.hidden = 1\"

Answer 1

What I do when I'm looking for records with a "not true" condition (eg, false or nil) is:

Post.where(["(hidden IS NULL) OR (hidden = ?)", false])
