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

In rails 4 there is not suffix for this purpose:

Post.where.not(hidden: true).to_sql
# => SELECT FROM `posts` WHERE `posts`.`hidden` != 1

In rails 3 you can use squeel gem. It gives many usefull features. And with it you can write:

Post.where{ hidden != true }.to_sql
# => SELECT FROM `posts` WHERE `posts`.`hidden` != 1
