When Active Record Child Objects are Autosaved in Rails

belongs_to:

  1. Assigning an object to a belongs_to association does not automatically save the object. It does not save the associated object either.

has_one:

  1. When you assign an object to a has_one association, that object is automatically saved (in order to update its foreign key).
  2. In addition, any object being replaced is also automatically saved, because its foreign key will change too
  3. If either of these saves fails due to validation errors, then the assignment statement returns false and the assignment itself is cancelled.
  4. If the parent object (the one declaring the has_one association) is unsaved (that is, new_record? returns true) then the child objects are not saved. They will automatically when the parent object is saved.

Created April 5, 2017 19:58
Rake task to transfer Sidekiq jobs from one redis instance to another
# This task should be run inside an environment that is already configured to connect to the redis
# instance that we're transfering AWAY FROM.
#
# The task should be handed the URL of the redis instance that we're MOVING TO.
#
# To run it and pass in the destination Redis you'd do something like this:
# rake sidekiq:transfer[redis://...]
#
# As jobs are added to the destination Redis, they're deleted from the source Redis. This
# allows the task to be restarted cleanly if it fails in the middle due to a network error
