Just to clarify the reason behind this, in Ruby 1.9 { foo:bar } translates
into { :foo => bar }. Since you want a has using constants as keys, the
shorthand notation doesn't work. In other words, your first example
translates to:
psc_options = { :NSMigratePersistentStoresAutomaticallyOption =>
NSN
Greetings,
I was trying to set up automatic migration, and did this brain-o, which will
be obvious to most folks, but stumped me for a little bit:
psc_options = {
NSMigratePersistentStoresAutomaticallyOption:NSNumber.numberWithBool(true),
NSInferMappingModelAutomaticallyOption:NSNumber.n
