Factory DRY patterns

CRIMINALLY INVASIVE HACKS in Factory.

class crudlfap.factory.Factory

Adds clumsy but automatic getter resolving.

The __getattr__ override makes this class try to call a get_*() method for variables that are not in self.__dict__.

For example, when self.foo is evaluated and ‘foo’ not in self.__dict__ then it will call the self.get_foo()

If self.get_foo() returns None, it will try to get the result again from self.__dict__. Which means that we are going to witness this horrroorr:

class YourEvil(Factory):
    def get_foo(self):
        self.calls += 1
        self.foo = 13

assert YourEvil.foo == 13   # crime scene 1
assert YourEvil.foo == 13   # crime scene 2
assert YourEvil.calls == 1  # crime scene 3

For the moment it is pretty clumsy because i tried to contain the criminality rate as low as possible meanwhile i like the work it does for me !

classmethod clone(*mixins, **attributes)

Return a subclass with the given attributes.

If a model is found, it will prefix the class name with the model.

class crudlfap.factory.FactoryMetaclass

__getattr__ that ensures a first argument to getters.

Makes the getter work both from class and instance

Thanks to this, your get_*() methods will /maybe/ work in both cases:

YourClass.foo   # calls get_foo(YourClass)
YourClass().foo # calls get_foo(self)

Don’t code drunk.

get_cls()

Return the cls.

did it go to far at this point ?
