在 CakePHP 中定义模型类的层次结构
默认情况下，CakePHP 有一个 AppModel 类，应用程序的每个模型都继承自它。在模型之间共享逻辑的常见设计模式是创建行为并将模型配置为 $actAs 该行为。
但是，如果我想引入这样的模型类层次结构怎么办？：
AppModel
|__ Vehicle
|__ Car
|__ Bike
|__ Helicopter
我尝试创建一个继承自 AppModel 的 Vehicle 类，然后每个子类都继承自车辆。但 CakePHP 告诉我它找不到类 Vehicle。
我怎样才能做到这一点以及我应该在 CakePHP 目录树中的什么位置创建 Vehicle？
谢谢！
By default CakePHP has a AppModel class and every model of an application inherits from it. A common design pattern to share logic between models is to create a behavior and configure a model to $actAs that behavior.
But what if I wanted to introduce a hierarchy of model classes like this?:
AppModel
|__ Vehicle
|__ Car
|__ Bike
|__ Helicopter
I have tried to create a Vehicle class that inherits from AppModel, and then every children class inherits from Vehicle. But CakePHP tells me it cannot find the class Vehicle.
How could I make this and where in the CakePHP directory tree should I create Vehicle?
Thanks!

这样做应该不成问题
您只需要在声明之前确保 app::import() 是“父模型”。
或者你做了什么导致找不到模型？
如果我这样做，我会使用一个库作为我的“车辆”
它不一定是模型目录中的模型，
例如应用程序::导入('库','车辆');
Vehicle 扩展了 AppModel
Car 扩展了 Vehicle
it should not be a problem to do so
you only need to make sure you app::import() the "parent model" before you declare it.
or what did you do that the model cannot be found?
If I do sth like that I use a lib to be my "vehicle"
it does not have to be a model in the model directory
e.g. App::import('Lib', 'Vehicle');
Vehicle extends AppModel
Car extends Vehicle
