Custom field to add multiple boolean features using a BigIntegerField.

Project description

Django BigFeat is custom field to add up to 63 boolean features using a BigIntegerField.

Quick start

from django.db import models
from bigfeat import BigFeatField

class ModelWithOptionalFeatures(models.Model):
    FEATURES = {
        'FEATURE_1'  : 0x0000000000000001,
        'FEATURE_2'  : 0x0000000000000002,
        'FEATURE_3'  : 0x0000000000000004,
        'FEATURE_4'  : 0x0000000000000008,
        ...
        'FEATURE_61' : 0x1000000000000000,
        'FEATURE_62' : 0x2000000000000000,
        'FEATURE_63' : 0x4000000000000000,
    }
    features = BigFeatField(masks=FEATURES)

m = ModelWithOptionalFeatures.objects.get(id=1)
print m.features.feature_1
if m.features.feature_2:
    print m.features.feature_3 if m.features.feature_4 else m.features.feature_5
print m.features

Notes

The most significant bit (0x8000000000000000) cannot be used since BigIntegerField is stored as a signed integer and will cause an OverflowError
