Root for all validators, mainly for documentation purposes. Validators are classes used to validate input fields (including forms generated from database tables). Here is an example of using a validator with a FORM:: INPUT(_name='a', requires=IS_INT_IN_RANGE(0, 10)) Here is an example of how to require a validator for a table field:: db.define_table('person', SQLField('name')) db.person.name.requires=IS_NOT_EMPTY() Validators are always assigned using the requires attribute of a field. A field can have a single validator or multiple validators. Multiple validators are made part of a list:: db.person.name.requires=[IS_NOT_EMPTY(), IS_NOT_IN_DB(db, 'person.id')] Validators are called by the function accepts on a FORM or other HTML helper object that contains a form. They are always called in the order in which they are listed. Built-in validators have constructors that take the optional argument error message which allows you to change the default error message. Here is an example of a validator on a database table:: db.person.name.requires=IS_NOT_EMPTY(error_message=T('Fill this')) where we have used the translation operator T to allow for internationalization. Notice that default error messages are not translated. |

Abstract classes can override this to customize issubclass(). This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached). |
