使用 PyAMF / Django 实现 Flex 类映射

from django.contrib.auth.models import User
from pyamf.flex import *

class Talent(User, IExternalizable):
    street = models.CharField(max_length=100)
    street_nr = models.CharField(max_length=100)
    postal_code = models.PositiveIntegerField()
    city = models.CharField(max_length=100)
    description = models.CharField(max_length=100)

    def __externalize__(self):
        return {
            'id': self.id,
            'username': self.username,
            'first_name': self.first_name,
            'last_name': self.last_name,
            'email': self.email,
            'street': self.street,
            'street_nr': self.street_nr,
            'postal_code': self.postal_code,
            'city': self.city,
            'description': self.description,
        }

    @classmethod
    def __internalize__(cls, data):
        talent = cls(**data)
        return talent
```python

在 Flex 端，可以使用以下代码来注册 IExternalizable 类：

```python
[Bindable]
public class Investor extends Externalizable {

    public static var ALIAS:String = "be.addestino.battleoftalents.model.Investor";

    public var id:Object;
    public var street:String;
    public var street_nr:String;
    public var postal_code:uint;
    public var city:String;
    public var cash:Number;
    public var date_created:Date;
    public var date_modified:Date;
    public var username:String;
    public var password:String;
    public var email:String;

    public function Investor() {
    }

    override public function writeExternal(output:IExternalizable):void {
        super.writeExternal(output);
        output.writeObject(id);
        output.writeUTF(street);
        output.writeUTF(street_nr);
        output.writeUInt(postal_code);
        output.writeUTF(city);
        output.writeNumber(cash);
        output.writeObject(date_created);
        output.writeObject(date_modified);
        output.writeUTF(username);
        output.writeUTF(password);
        output.writeUTF(email);
    }

    override public function readExternal(input:IExternalizable):void {
        super.readExternal(input);
        id = input.readObject();
        street = input.readUTF();
        street_nr = input.readUTF();
        postal_code = input.readUInt();
        city = input.readUTF();
        cash = input.readNumber();
        date_created = input.readObject() as Date;
        date_modified = input.readObject() as Date;
        username = input.readUTF();
        password = input.readUTF();
        email = input.readUTF();
    }

}
