输入定义可选键

sails.js

我用 sails generate action task/update-task . 我现在试图创建一个输入参数,该参数应该是一个具有可选键的对象:

  inputs: {
    fields: {
      type: {
        body: 'string?',
        rruleSetStr: 'string?',
      },
      required: true,
      description: 'All keys are not required, but at least one is'
    },

但是我一直有错误:

 The action `task/update-task` could not be registered.  It looks like a machine definition (actions2), but it could not be used to build an action.
Details: ImplementationError: Sorry, could not interpret "task/update-task.js" because its underlying implementation has a problem:
------------------------------------------------------
â¢ Invalid input definition ("fields").  Unrecognized `type`.  (Must be 'string', 'number', 'boolean', 'json' or 'ref'.  Or set it to a type schema like `[{id:'number', name: {givenName: 'Lisa'}}]`.)
------------------------------------------------------

If you are the maintainer of "task/update-task.js", then you can change its implementation to solve the problem above.  Otherwise, please file a bug report with the maintainer, or fork your own copy and fix that.

是否有人知道文档中关于如何在此中生成可选密钥的位置?我试过了- http://node-machine.org/spec/machine#inputs -但没有运气。

类型必须是'string'、'number'、'boolean'、'json'或'ref',就像error say一样。因此,您需要将type设置为'ref'(对象或数组),并且可以使用自定义函数进行验证。

inputs: {
        fields: {
            type: 'ref',
            custom: function (data) {
                // some logic
                // example
                if (typeof data.body !== "string") {
                    return false;
                    // or u can use trow Error('Body is not a string')
                }
                return true;
            },
            required: true,
            description: 'All keys are not required, but at least one is'
        }

现在输入是type object和in custom function return false 或 trow Error('Some problem') 中断验证。

如果使用模式类型,只需删除 ? 从你的例子来看:

inputs: {
        fields: {
            type: {
              body: 'string',
              rruleSetStr: 'string'
            },
            required: true,
            description: 'All keys are not required, but at least one is'
        }

这是 Runtime (recursive) type-checking for JavaScript. ,请检查文档以了解编写规则。
