Writing a __init__ function to be used in django model


Question

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?

Accepted Answer

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

p = User(name="Fred", email="fred@example.com")

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
@classmethod
def create(cls, name, email):
  return cls(name=name, email=email)

# Use it
p = User.create("Fred", "fred@example.com")

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.
