如何在SimpleSchema Meteor中定义一个具有自动值的子文档，而不将其插入每个父文档插入中？

Question

I'm trying to define a schema for a collection with a sub document, both parent and sub documents have autovalue fields that should get set on inserts. 我正在尝试为带有子文档的集合定义一个架构，父文档和子文档都具有应在插入项上设置的自动值字段。 The problem is that when I try to insert a new parent document (without any sub documents) I get an error stating that the sub-document fields are required. 问题是当我尝试插入新的父文档（不包含任何子文档）时，出现错误消息，指出子文档字段是必需的。

Here is the full code to reproduce the problem: 这是重现该问题的完整代码：

main.js main.js

ChatRooms = new Meteor.Collection("chatRooms");

schema_ChatRooms_ChatMesssage = new SimpleSchema({
    userId: {
        type: String,
        label: "User ID",
        autoValue: function() {
            if (this.isInsert) {
              if (! this.isFromTrustedCode) {
                return this.userId;
              }
            } else {
              this.unset();
            }},
        autoform: { omit: true }
    },
    content: {
        type: String,
        label: "Content",
        max: 1000,
        min: 1
    },
    creationDate: {
        type: Date,
        label: "Created On",
        autoValue: function() {
            if (!this.isSet) {
                return new Date();
            }
            else {
              this.unset();
            }},
        autoform: { omit: true }
    }
});

schema_ChatRoom = new SimpleSchema({
    name: {
        type: String,
        label: "Name",
        max: 50,
        min: 1
    },
    isPublic: {
        type: Boolean,
        label: "Public"
    },
    creationDate: {
        type: Date,
        label: "Created On",
        autoValue: function() {
            if (!this.isSet) {
                return new Date();
            }
            else {
              this.unset();
            }},
        autoform: { omit: true }
    },
    // Sub Documents
    chatMessages: {
        type: schema_ChatRooms_ChatMesssage,
        label: "Chat Messages",
        optional: true,
        autoform: { omit: true }
    }
});

ChatRooms.attachSchema(schema_ChatRoom);

if (Meteor.isClient) {
    AutoForm.addHooks(null, {
        onError: function(operation, error, template) {
                    alert(operation.toString() + " : " + error.toString());
                }
    });
}

main.html main.html中

<head>
  <title>TestSubDoc</title>
</head>

<body>
  <h1>Create</h1>

  {{> quickForm collection="ChatRooms" id="chatRooms_create_form" type="insert"}}
</body>

I've tried adding an "optional: true" to "chatMessages" but it didn't solve it. 我试过在“ chatMessages”中添加一个“ optional：true”，但没有解决。 It seems like even when a sub-document is not included the sub-document autovalue still gets executed and creates a new subdocument with the generated values. 似乎即使不包含子文档，该子文档自动值仍然会执行并使用生成的值创建一个新的子文档。

What can I do to properly create a document with sub-documents that have auto values? 如何正确地创建带有自动值的子文档的文档？

可能您需要将schema_ChatRooms_ChatMesssage中的所有字段设置为可选，并通过自动形成功能将其忽略。
