在 treeline.io 中处理来自机器的对象数组
Processing array of objects from Machine in treeline.io
我在 treeline.io 中创建了一个自定义机器，用于搜索 Twitter 和 returns 我想作为模型插入到我的数据库中的对象数组。
返回数组的格式如下：
[
{
"postText": "RT @TheJWittz: MEWTWOOOOOOOOO http://t.co/ZzZsiGIDE4",
"postID": "583388726883180500",
"postStatus": "new",
"postDate": "Wed Apr 01 22:01:25 +0000 2015",
"postScheduleDate": "",
"postUserImageURL": "http://pbs.twimg.com/profile_images/569178372899487744/YqHkhlli_normal.jpeg",
"postUserRealName": "",
"postUserName": "",
"postUpdateUser": "",
"postType": "twitter",
"postStatusDate": "2015-04-01T22:01:50.745Z",
"postHasImage": true,
"postImagePreviewURL": "http://pbs.twimg.com/media/CBiczM2UoAAMSQa.png:small",
"postImageURL": "http://pbs.twimg.com/media/CBiczM2UoAAMSQa.png",
"postHasVideo": false,
"postVideoPreviewURL": "",
"postVideoURL": ""
}
]
我正在尝试使用 "each" 机器并告诉它将数组中的每个项目传递到我的 "Create Post" 机器，它应该创建一个新的 Post。然而，当我尝试这样做时它会抛出大量错误，我猜它在理解它所给的对象时遇到了问题，或者某些值不匹配。不管怎样，我有点卡住了。
这是我在加载路由时在控制台中得到的内容：
error: Sending 500 ("Server Error") response:
Error: `create_post` machine encountered 17 error(s) while validating runtime input values.

循环机是我们在 Treeline 中迭代（没有双关语意）的东西。您遇到的问题是由于 Treeline 为您生成的 Create Post 机器每个模型属性有一个输入，但 Each 机器天真地只发送一个输入到 "worker".
为此，我们想到了几个即将推出的解决方案，但与此同时，最简单的做法是创建您自己的 Create Post from Dictionary 机器，这是一个接受电路的电路与 Post 对象的架构匹配的单个输入（例如 dict），并包含 Create Post 的单个实例，其中每个输入都由 [=13= 的属性填充].然后你可以使用 Create Post from Dictionary 作为 Each 的 "worker"。
