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

With a different syntax, yes. Example:

posts = Post.scoped.table # or Arel::Table.new("posts")
posts.where(posts[:hidden].eq(true).not).to_sql
# => SELECT  FROM `posts` WHERE NOT ((`posts`.`hidden` = 1))
