如何控制 RemoteObject 方法中传递的参数?我注意到,当我直接从该站点下载并运行代码时,保存对象会导致以下参数集被传回:
Processing PostsController#save (for 127.0.0.1 at 2011-02-01 23:34:55) [POST]
Parameters: {0=>{"post"=>#<Post id: nil, title: "a", body: "b", created_at: nil, updated_at: nil>}, "post"=>#<Post id: nil, title: "a", body: "b", created_at: nil, updated_at: nil>}
而我自己的项目(基本上涉及与该教程中相同的步骤)进行保存,提供类似
Processing CarsController#save (for 127.0.0.1 at 2011-02-01 22:34:56) [POST]
Parameters: {0=>{"car"=>#<Car id: nil, user_id: 0, name: "asdfCar", body_id: 3, theme: nil, deleted: nil, photo_file_name: nil, photo_content_type: nil, photo_file_size: nil, photo_updated_at: nil, created_at: nil, updated_at: nil>}}
澄清一下,不同之处在于对帖子控制器的请求似乎收到了帖子的两份副本,一份作为 params[0]["post"],一份作为 params["post"],而我的代码只给出了一份。
似乎定义 RemoteObject 调用的唯一代码是
<mx:RemoteObject id="postRO" destination="rubyamf" endpoint="rubyamf/gateway" source="PostsController" showBusyCursor="true" fault="onFault(event)">
<mx:method name="index" result="onIndexResult(event)"/>
<mx:method name="save" result="onSaveResult(event)"/>
<mx:method name="destroy" result="onDestroyResult(event)"/>
</mx:RemoteObject>
private function onAddPost(event:MouseEvent):void
{
var post:PostVO = new PostVO();
post.title = addTitleText.text;
post.body = addBodyText.text;
post.comments = new Array();
postRO.getOperation("save").send({post:post});
}
然后值对象定义是
package com.unitedmindset.vo
{
[RemoteClass(alias="PostVO")]
[Bindable]
public class PostVO
{
public function PostVO()
{
}
public var id:int;
public var title:String;
public var body:String;
public var createdAt:Date;
public var updatedAt:Date;
public var comments:Array;
}
}
而我自己的代码看起来非常相似
private function onAddCar(event:MouseEvent):void
{
var car:CarVO = new CarVO();
car.name = addNameText.text;
car.bodyId = int(addBodyIdText.text);
car.componentInstances = new Array();
carRO.getOperation("save").send({car:car});
}
<mx:RemoteObject id="carRO" destination="rubyamf" endpoint="http://localhost:3000/rubyamf/gateway" source="CarsController" showBusyCursor="true" fault="onFault(event)">
<mx:method name="index" result="onIndexResult(event)"/>
<mx:method name="save" result="onSaveResult(event)"/>
<mx:method name="destroy" result="onDestroyResult(event)"/>
</mx:RemoteObject>
<mx:RemoteObject id="componentInstanceRO" destination="rubyamf" endpoint="http://localhost:3000/rubyamf/gateway" source="ComponentInstancesController" showBusyCursor="true" fault="onFault(event)">
<mx:method name="save" result="onCreateComponentInstanceResult(event)"/>
</mx:RemoteObject>
package com.foo.vo
{
[RemoteClass(alias="CarVO")]
[Bindable]
public class CarVO
{
public function CarVO()
{
}
public var id:int;
public var userId:int;
public var name:String;
public var bodyId:int;
public var createdAt:Date;
public var updatedAt:Date;
public var componentInstances:Array;
}
}
我假设有某种配置设置(大概在 Flex 中),但我不知道它是什么。关于在哪里看的任何建议?谢谢。
