Writing a __init__ function to be used in django model

Question

Hi,

I'm trying to write an init function for one of my models so that I can create an object by doing

p = User('name','email')

When I write the model, I have

    def __init__(self, name, email, house_id, password):
            models.Model.__init__(self)
            self.name = name
            self.email = email

This works, and I can save the object to the database, but when I do 'User.objects.all()', it doesn't pull anything up unless I take out my __init__ function. Any ideas?

Answer 1

Django expects the signature of a model's constructor to be (self, *args, **kwargs), or some reasonable facsimile. Your changing the signature to something completely incompatible has broken it.

Answer 2

Relying on Django's built-in functionality and passing named parameters would be the simplest way to go.

p = User(name="Fred", email="[email protected]")

But if you're set on saving some keystrokes, I'd suggest adding a static convenience method to the class instead of messing with the initializer.

# In User class declaration
def create(name, email)
  return User(name=name, email=email)
create = staticmethod(create)

# Use it
p = User.create("Fred", "[email protected]")
