MultiValueEnum with attribute as another enum

[developer992]

why wouldn't this work:

class WarningLevel(enum.Enum):
    INFO = 1
    WARNING = 2
    ERROR = 3

class WarningType2(aenum.MultiValueEnum):
    ONE = 1, "This is rule #1", WarningLevel.INFO
    TWO = 2, "This is rule #2", WarningLevel.ERROR
    THREE = 3, "This is rule #3", WarningLevel.INFO

it fails here but i don't see why this is necessary constraint and further more, how do i get around it?

aenum/_enum.py:973:

if enum_class._multivalue_ and (
        value in enum_class._value2member_map_
        or any(v == value for (v, m) in enum_class._value2member_seq_)
    raise ValueError('%r has already been used' % (value, ))

Not even this works:

class X1(aenum.MultiValueEnum):
    ONE = 1, 1

The purpose of a MultiValueEnum is to have several different values that correspond to one enum member. In your WarningType2 if you tried WarningType2(WarningLevel.INFO it would know if you wanted ONE or THREE.

It looks like what you really want are attributes:

class WarningType2(aenum.Enum):
    _init_ = "value text level"
    ONE = 1, "This is rule #1", WarningLevel.INFO
    TWO = 2, "This is rule #2", WarningLevel.ERROR
    THREE = 3, "This is rule #3", WarningLevel.INFO

and in use:

>>> WarningType2.TWO.level
WarningLevel.ERROR
