对象数组的SimpleSchema验证

Question

我想验证此对象数组：

[
    {
        _id     : 'NpxZFT4TwfDvwbtKX',
        parent: 'T4TwfDvwbtKXNpxZF',
        order:  1
    }
]

我怎么办，因为这不起作用：

new SimpleSchema({
    _id   : { type: SimpleSchema.RegEx.Id },
    parent: { type: SimpleSchema.RegEx.Id },
    order : { type: Number }
})

通过使用check()进行验证的方式如何？

关于经过验证的方法，最酷的事情是，您可以为方法使用独立的架构，而不是为文档使用架构。 这使您可以将对象和数组以及其他任何内容传递给方法，并代表数据处理文档。

那么您之前创建的架构呢？ 这仍在使用中！ 如果文档适合给定的架构，它将检查文档中每个文档的插入或更新。

代码示例：

import {Meteor} from 'meteor/meteor';
import {Mongo} from 'meteor/mongo';
import {ValidatedMethod} from 'meteor/mdg:validated-method';
import {Random} from 'meteor/random';

import SimpleSchema from 'simpl-schema';

// schema for document on collectionm level
const documentSchema = new SimpleSchema({
    // id optional otherwise you can't insert new docs
    _id: {type: SimpleSchema.RegEx.Id, optional: true},
    parent: {type: SimpleSchema.RegEx.Id},
    order: {type: Number}
});

// attach schema to a new collection
const testCollection = new Mongo.Collection("testcollection");
testCollection.schema = documentSchema;
testCollection.attachSchema(documentSchema)


// create method schema
// see that we attach the document schema
// as type of the items of the array
const methodSchema = new SimpleSchema({
    data: {type: Array},
    "data.$": {type: documentSchema},
});

// insert method using the method schema
const insertArrayMethod = new ValidatedMethod({
    name: "insert.array.method",
    validate: methodSchema.validator(),
    run({data}){
        const ret = [];
        for (let input of data) {
            const tmp = Object.assign({}, input);
            tmp._id = testCollection.insert(input);
            ret.push(tmp);
        }
        return ret;
    },
});

// update method using the method schema
const updateArrayMethod = new ValidatedMethod({
    name: "update.array.method",
    validate: methodSchema.validator(),
    run({data}){
        const ret = [];
        for (let input of data) {
            ret.push(testCollection.update(input._id, {$set: {parent: input.parent, order: input.order}}));
        }
        return ret;
    },
});


Meteor.startup(() => {
    const data = [
        {parent: Random.id(17), order: 0},
        {parent: Random.id(17), order: 1},
        {parent: Random.id(17), order: 2},
    ];
    console.log("insert data")
    console.log(data);

    const results = Meteor.call("insert.array.method", {data: data});
    console.log("insert result");
    console.log(results);

    for (let element of results) {
        element.order += 5;
    }
    console.log("update data");
    console.log(results);

    // note thet the input variablle in the validated method has to be called data
    const updateResult = Meteor.call("update.array.method", {data: results});
    console.log("update result");
    console.log(updateResult);
});

控制台输出：
