Metaclasses
|
|
-----------
|
|
|
|
Python 3 and Python 2 syntax for metaclasses are incompatible.
|
|
``future`` provides a function (from ``jinja2/_compat.py``) called
|
|
:func:`with_metaclass` that can assist with specifying metaclasses
|
|
portably across Py3 and Py2. Use it like this::
|
|
|
|
from future.utils import with_metaclass
|
|
|
|
class BaseForm(object):
|
|
pass
|
|
|
|
class FormType(type):
|
|
pass
|
|
|
|
class Form(with_metaclass(FormType, BaseForm)):
|
|
pass
