[storm] self-referencing table

[Wilson Freitas]

Hi all,

Is it possible to use storm to handle self-referencing tables ?
I have made a trial with the following code:

class Category(object):
    __storm_table__ = "category"
    id = Int(name="id_category", primary=True)
    name = Unicode()
    id_parent = Int()
    parent = Reference(id_parent, Category.id)

    def __init__(self, name):
        self.name = name

But I have got a NameError, because Category was already not defined.
I also have tried this code:

class Category(object):
    __storm_table__ = "category"
    id = Int(name="id_category", primary=True)
    name = Unicode()
    id_parent = Int()
    parent = None

    def __init__(self, name):
        self.name = name
        self.parent = Reference(self.id_parent, Category.id)

and it does not worked too.
Is there any way to make this work?

Thank you in advance.
