Description

<type 'type'> extends (<class 'gluon.validators.Validator'>,)


    Example:
        Used as::

            INPUT(_type='text', _name='name', requires=IS_NOT_EMPTY())

            >>> IS_NOT_EMPTY()(1)
            (1, None)
            >>> IS_NOT_EMPTY()(0)
            (0, None)
            >>> IS_NOT_EMPTY()('x')
            ('x', None)
            >>> IS_NOT_EMPTY()(' x ')
            ('x', None)
            >>> IS_NOT_EMPTY()(None)
            (None, 'enter a value')
            >>> IS_NOT_EMPTY()('')
            ('', 'enter a value')
            >>> IS_NOT_EMPTY()('  ')
            ('', 'enter a value')
            >>> IS_NOT_EMPTY()(' \n\t')
            ('', 'enter a value')
            >>> IS_NOT_EMPTY()([])
            ([], 'enter a value')
            >>> IS_NOT_EMPTY(empty_regex='def')('def')
            ('', 'enter a value')
            >>> IS_NOT_EMPTY(empty_regex='de[fg]')('deg')
            ('', 'enter a value')
            >>> IS_NOT_EMPTY(empty_regex='def')('abc')
            ('abc', None)

Attributes


IS_NOT_EMPTY.__call__	<type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_NOT_EMPTY.__class__	<type 'type'> extends (<type 'object'>,) belongs to class <type 'type'> type(object) -> the object's type type(name, bases, dict) -> a new type

IS_NOT_EMPTY.__delattr__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__delattr__('name') <==> del x.name

IS_NOT_EMPTY.__dict__	<type 'dictproxy'> belongs to class <type 'dictproxy'>

IS_NOT_EMPTY.__doc__	<type 'str'> belongs to class <type 'str'> str(object='') -> string Return a nice string representation of the object. If the argument is a string, the return value is the same object.

IS_NOT_EMPTY.__format__	<type 'method_descriptor'> belongs to class <type 'method_descriptor'> default object formatter

IS_NOT_EMPTY.__getattribute__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__getattribute__('name') <==> x.name

IS_NOT_EMPTY.__hash__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__hash__() <==> hash(x)

IS_NOT_EMPTY.__init__	<type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_NOT_EMPTY.__module__	<type 'str'> belongs to class <type 'str'> str(object='') -> string Return a nice string representation of the object. If the argument is a string, the return value is the same object.

IS_NOT_EMPTY.__new__	<type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'> T.__new__(S, ...) -> a new object with type S, a subtype of T

IS_NOT_EMPTY.__reduce__	<type 'method_descriptor'> belongs to class <type 'method_descriptor'> helper for pickle

IS_NOT_EMPTY.__reduce_ex__	<type 'method_descriptor'> belongs to class <type 'method_descriptor'> helper for pickle

IS_NOT_EMPTY.__repr__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__repr__() <==> repr(x)

IS_NOT_EMPTY.__setattr__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__setattr__('name', value) <==> x.name = value

IS_NOT_EMPTY.__sizeof__	<type 'method_descriptor'> belongs to class <type 'method_descriptor'> __sizeof__() -> int size of object in memory, in bytes

IS_NOT_EMPTY.__str__	<type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'> x.__str__() <==> str(x)

IS_NOT_EMPTY.__subclasshook__	<type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'> 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).

IS_NOT_EMPTY.__weakref__	<type 'getset_descriptor'> belongs to class <type 'getset_descriptor'> list of weak references to the object (if defined)

IS_NOT_EMPTY.formatter	<type 'instancemethod'> belongs to class <type 'instancemethod'> For some validators returns a formatted version (matching the validator) of value. Otherwise just returns the value.
