要使用类中的选项，请定义一个选项类，并使用提供的元类生成器之一。

from django import forms
from django.utils import six
from easyoption.options import OptionsBase, form_option_factory


# Define your ``Option``\s container class
class ExtendedOptions(OptionsBase):
    def __init__(self, options):

        # Collect your options, supplying defaults as appropriate
        self.foo = options.pop('foo', None)
        self.frobnicate = options.pop('frobnicate', True)

        # Call the ``super().__init__()``, which ensures all options are
        # consumed.
        super(ExtraOption, self).__init__(options)


# Define your base class, using the options from ``_extendedoptions``
class ExtendedForm(six.with_metaclass(
        form_option_factory(ExtendedOptions),
        forms.Form)):

    def __init__(self, **kwargs):
        super(ExtendedForm, self).__init__(**kwargs)

        if self._extendedoptions.frobnicate:
            self.bar(self._extendedoptions.foo)


# Extend your base class, and define the ``ExtendedOptions`` for options
# for this specific implementation
class SpecificExtendedForm(ExtendedForm):
    class ExtendedOptions:
        foo = 'quux'
