Handle null values #12

Closed cayuu closed 8 years ago

cayuu commented 9 years ago

Providing a mechanism to treat null values as "special" is important.

  1. [ ] NOT DOING .createFrom( scm ) (ie a format method) generates fields with undefined values where no "default" or "generate" is set - these undefined fields are removed entirely when serialised to JSON. Being able to specify an emptyValue would be handy to ensure empty fields persist post-serialisation
  2. [x] Conversely, when receiving de-serialised data in validate() it would be useful to treat null as being "ok".

Recent commit f93d464a enabled an allowNull model descriptor that disables validation if user provides null as the value to validate.

The emptyValue issue is simply not required at this point as the use-case (JSON stripping undefined) fields seems fine. Closing.
