Usage
Here is an example on how to use a soft deletable document:
from mongoengine_softdelete.document import SoftDeleteNoCacheDocument
class IceCream(SoftDeleteNoCacheDocument):
meta = {
'collection': 'ice_cream',
'soft_delete': {'deleted': True},
'indexes': [ 'flavor' ],
'strict': False
}
flavor = fields.StringField(required=True)
color = fields.StringField(required=True)
price = fields.FloatField(default=0)
created_at = fields.DateTimeField()
# Declare the field used to check if the record is soft deleted
# this field must also be reported in the `meta['soft_delete']` dict
deleted = fields.BooleanField(default=False)
# Save a new document
ice = IceCream(flavor="Vanilla", color="White").save()
assert not ice.is_soft_deleted
# Mark the document as soft deleted
ice.soft_delete()
assert len(IceCream.objects()) == 0
assert ice.is_soft_deleted
# Soft undelete the document
ice.soft_undelete()
assert len(IceCream.objects()) > 0
assert not ice.is_soft_deleted
