I have a field regex which contains requires segements like "IS_MATCH('^ \d{3}-\d{4}-\d{4}-\d{1}?$')" in an administrative table
I store them as as Storage types and then retrieve and apply it to a Form like this: Field('f4', requires=IS_EMPTY_OR(settings.regex[4])) In a model file, it's defined as: settings=Storage() settings.regex={ 0:IS_MATCH('^\d{3}-\d{4}-\d{4}-\d{1}?$'), 1:IS_MATCH('^\d{4}-\d{3}-\d{3}-\d{1}?$'), } That worked fine. Now, however, I couldn't use the values I retrieve from a record field because they are strings. I hope to use it like this ... record=db.id_card_number(person==1,card==2) form=SQLFORM.factory(Field('f4','string')) form.f4.requires=record.regex ... /r, Nik
