The best answer would be to look at the code :) ... but in a glance
here it is:
1. For each Field you can add virtually any number a validation
functions. Each validation function takes parameter the type of the
field (Int, Long String etc.) and returns a Can[Node]. If Can is Empty
the validation passed. Otherwise the Node impersonates the error text
that will be shown as validation message.
2. In the validation function you have access to all other Record
fields if you have fields dependency validation.
3. When you call validate on a record it will subsequently call all
validators for each field and Return a List[FieldError]. having this
list you can pass it to S.error for example in order to set the
validation messages into the form
I could probably send you off line later on today a code example.
