Disable pylint warning E1101 when using enums

Question

I recently came across this article by Anthony Fox which shows how to use enums to create the choice set in django CharFields, which I thought was pretty neat.

Basically, you create a subclass of Enum:

from enum import Enum

class ChoiceEnum(Enum):
    @classmethod
    def choices(cls):
        return tuple((x.name, x.value) for x in cls)

Which can then be used in your models like so:

from .utils import ChoiceEnum

class Car(models.Model):
    class Colors(ChoiceEnum):
        RED = 'red'
        WHITE = 'white'
        BLUE = 'blue'

    color = models.CharField(max_length=5, choices=Colors.choices(), default=Colors.RED.value)

red_cars = Car.objects.filter(color=Car.Colors.RED.value)

However, pylint throws a warning whenever you try to access the enum value (Colors.RED.value)

E1101:Instance of 'str' has no 'value' member

Is there a way to avoid / disable this warning for every instance of ChoiceEnum?

This answer only works on the subclass of ChoiceEnum, not ChoiceEnum itself.

Answer 1

Since the issue is still open, we can use the following workaround

from .utils import ChoiceEnum

class Car(models.Model):
    class Colors(ChoiceEnum, Enum):
        RED = 'red'
        WHITE = 'white'
        BLUE = 'blue'

    color = models.CharField(max_length=5, choices=Colors.choices(), default=Colors.RED.value)

This doesn't create the pylint error now
