Hi everyone,
Auto validation on primary keys sucks because they often aren't know at
validation time (such as creating new objects in a tree - the children
don't know the FK, which is often a part of the PK, until after
validation and after save of the parent).
I am using the following monkey patch in my current project to default
auto_validation on PKs to false, but still allow it to be overridden to
true. How do people feel about making it default behaviour?
module DataMapper
module Validations
module AutoValidations
def skip_auto_validation_for?(property)
(property.key? && !property.options[:auto_validation]) ||
(property.options.key?(:auto_validation) &&
!property.options[:auto_validation])
end
end
end
end
Another behaviour I've noted is that :auto_validation on a belongs_to
isn't passed down to the properties, but I think this is a real bug so
will put together a proper test case/patch for it.
