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.

Enable key repeat in Apple Lion for Sublime Text in Vim mode
# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.
