Overview

This cop checks for migrations that use references instead of belongs_to.

Instead of adding references in migrations, use the belongs_to alias. It reads nicer and is more similar to the belongs_to declarations that you find in model code.

Examples:

# bad
def change
  add_reference :blog_posts, :user
end

# good
def change
  add_belongs_to :blog_posts, :user
end
