从视图中。操作方法并不需要有该属性被用作一个子动作，但
我们倾向于使用这个属性prevent被援引为用户所造成的动作方法
请求。
在定义的操作方法，我们需要创造什么将被渲染时动作
调用。子的动作通常与局部视图相关联的，尽管这不是强制性的。
The ChildActionOnly attribute ensures that an action method can be called only as a child method
from within a view. An action method doesn’t need to have this attribute to be used as a child action, but
we tend to use this attribute to prevent the action methods from being invoked as a result of a user
request.
Having defined an action method, we need to create what will be rendered when the action is
invoked. Child actions are typically associated with partial views, although this is not compulsory.
