Last but not least..
--------------------

Rollback of 'where.like' and 'where.not_like' in Edge Rails
https://github.com/rails/rails/commit/8d02afeaee8993bd0fd...

  Recently, Akira Matsuda added handy #like and #not_like chainable methods
  to ActiveRecord's #where (e.g. Post.where.like(title: 'ruby
  on%'")). Sadly, this has now been rolled back with a rather lacking
  rationale.
