do_create(options = {})
click to toggle source
A somewhat complex method to actually create a new record. The complexity
is from support for subforms and associated records. If you want to
customize this behavior, consider using the before_create_save
and after_create_save
callbacks.

do_new()

A simple method to find and prepare an example new record for the form May be overridden to customize the behavior (add default values, for instance)
