@coleifer
I am trying to expire the key as below, but getting the object has no attribute expire error

from walrus import Model, TextField, DateTimeField, Database

db = Database(host="host", port="port")


class Hello(Model):
    __database__ = db

    name = TextField(primary_key=True)
    ...
    
user_drop = Hello.get(Hello.name == "some_name")
user_drop.expire(10)

Am I missing something or is there another way of handling it?

Models are not a good fit for simple expiry since they may contain a number of values stored in indexes, but if you are not using any indexes you can:

user_drop = Hello.get(...)
user_hash = user_drop.to_hash()  # Get corresponding hash.
user_hash.expire(10)  # Will expire the underlying hash, but not the data in the indexes.

To see what is necessary to remove from indexes, see the Model.delete() code in the models.py file. In short, models are composite data-structures are will not play well with simple expiration logic.
