def make_declarative_base(self, model, metadata=None) 

Description

make_declarative_base.__doc__

Creates the declarative base that all models will inherit from.

        :param model: base model class (or a tuple of base classes) to pass
            to :func:`~sqlalchemy.ext.declarative.declarative_base`. Or a class
            returned from ``declarative_base``, in which case a new base class
            is not created.
        :param metadata: :class:`~sqlalchemy.MetaData` instance to use, or
            none to use SQLAlchemy's default.

        .. versionchanged 2.3.0::
            ``model`` can be an existing declarative base in order to support
            complex customization such as changing the metaclass.
