Rails had provided an after_commit callback for ActiveRecord objects.
It is called after a record has been created, updated or destroyed.
We can also use below shortcut of after_commit when creating, updating or
destroying a record respectively:
- after_create_commit
- after_update_commit
- after_destroy_commit
Rails has a separate shortcut for create and update, but a common callback for creating or updating a record was missing.
Rails 6 introduces a shortcut for after_commit :hook, on: [:create, :update]
Before Rails 6:
class User < ApplicationRecord
after_commit :log_user_saved, on: [:create, :update]
private
def log_user_saved
puts "User saved successfully."
end
end
# Create user
@user = User.create
=> User saved successfully.
@user.save
=> User saved successfully.In Rails 6:
With the introduction of after_save_commit the above example can be
changed to below:
class User < ApplicationRecord
after_save_commit :log_user_saved
private
def log_user_saved
puts "User saved successfully."
end
end
# Create user
@user = User.create
=> User saved successfully.
@user.save
=> User saved successfully.
