At Django, a boolean field in MySQL is stored as a TINYINT. When I retrieve it, I get 0 or 1. Shouldn't I get False or True? Is there a way to achieve this behaviour?

推荐答案

您可以为您的模型创建自己的方法，为您评估： / p>

You could create your own method for your model that evaluates this for you:

class User(models.Model):
    active_status = models.BooleanField(default=1)

    def is_active(self):
        return bool(self.active_status)

然后，您对此字段执行的任何测试都可以引用该方法：

Then any tests you perform against this field could just reference the method instead:

>>> u.is_active()
True

您甚至可以将其设为属性： p>

You can even make this into a property:

class User(models.Model):
    active_status = models.BooleanField(default=1)

    @property    
    def is_active(self):
        return bool(self.active_status)

，以便该类的用户甚至不必知道它作为一种方法实现：

so that users of the class don't even have to know that it's implemented as a method:

>>> u.is_active
True
