MongoDB Atlas 设备同步（应用程序服务）-React Native

Question

我正在使用 MongoDB - 应用服务作为后端构建一个react-native-app。

一切都工作正常，直到我添加了自定义架构对象类型（User_location）。 SDK不想接受它。

这是我的用户模式模型：

import "react-native-get-random-values";
import Realm, { BSON, ObjectSchema } from "realm";
// import { User_location } from "./User_location";

export class User extends Realm.Object<User> {
  _id!: BSON.ObjectId;
  userName?: string;
  firstName?: string;
  lastName?: string;
  email!: string;
  avatar?: string;
  userId!: string;
  admin!: boolean;
  location?: User_location;

  static schema: ObjectSchema = {
    name: "User",
    primaryKey: "_id",
    properties: {
      _id: { type: "objectId", default: () => new BSON.ObjectId() },
      userName: "string?",
      firstName: "string?",
      lastName: "string?",
      email: "string",
      avatar: "string?",
      userId: "string",
      admin: "bool",
      location: "User_location?",
    },
  };
}

export class User_location extends Realm.Object {
  latitude!: number;
  longitude!: number;

  static schema: ObjectSchema = {
    name: "User_location",
    embedded: true,
    properties: {
      latitude: "double",
      longitude: "double",
    },
  };
}

我得到的错误：

[错误：在架构中找不到对象类型“User_Location”。]

我完全按照此处文档中的示例进行操作： [https://www.mongodb.com/docs/realm/sdk/react-native/model-data/relationships-and-embedded-objects/]

我为 ObjectType 定义了一个类并将其用作 SchemaType，如文档中所示，但它仍然不知道类型。我在这里错过了什么？

您必须将 User_location 架构与其他架构一起传递到 schema 属性中才能正常工作

看起来像这样

<RealmProvider
schema = [...otherSchemas,User_location]
...
//other props
>{children}
</RealmProvider>
