left_join
This gem helps you doing LEFT JOINs between your ActiveRecord associations, so
you can do this:
Book.left_join(:category)
# SELECT "books".* FROM "books"
# LEFT OUTER JOIN "categories"
# ON "books"."category_id" = "categories"."id"It also supports chaining associations, e.g. Category.left_join(books: :authors).
Why?
See this blog post for details.
