That advice is for normal python classes. Django models have some restrictions, one being that fields are special attributes. Messing with a model's __init__() is not something you normally do as a model's class creation is highly customized.

 

If you're really using 2 different databases, a model's save() operation supports a `using` keyword that allows you to select the database connection. Archiving becomes really easy that way.
