DataStore - 订阅错误，连接失败：

问题描述 投票：0回答：2

我正在开发 React Native、AWS、DynamoDB、Amplify 项目，并且正在努力向数据库添加额外的表（模型）。

最初的模式非常简单。 （可能太简单了，没有效果）

type Capture @model {
    id: ID!
    captureID: String!
    userID: String!
    moodScore: String
    emotion: String
    lifeAspect: String
    activity: String
    companions: String
    location: String
    date: String
    images: String
    journalEntry: String
}

用户不断捕捉生活中的瞬间。所有内容都存储为字符串（出于某种原因......）。

我正在尝试向应用程序添加更多表格。新表并未真正连接到当前表。连接数据和用户 ID 的唯一东西，是用户登录时从“amplify/auth”获得的。

我在 schema.graphql 中添加了第二个模型：

type Capture @model {
    id: ID!
    captureID: String!
    userID: String!
    moodScore: String
    emotion: String
    lifeAspect: String
    activity: String
    companions: String
    location: String
    date: String
    images: String
    journalEntry: String
}

type DbConversion @model {
    id: ID!
    userID: String!
    ConversionID: [String!]
}

我不希望在 DynameDB 中连接表。我想使用 DataStore 仅在用户登录时加载当前用户的数据。

let uuID = '';
// Configure datastore to sync based on user identifier.
DataStore.configure({
    syncExpressions: [
        syncExpression(Capture, () => {
            return (capture) => capture.userID('eq', uuID);
        }),
        syncExpression(DbConversion, () => {
            return (dbconversion) => dbconversion.userID('eq', uuID);
        }),
    ],
});

// Retrieve user ID and reset datastore sync with new data for uuID.
export async function changeSync() {
    uuID = await getData('userID');
    await DataStore.stop();
    await DataStore.start();
}

一切工作正常，直到我尝试添加第二个表。之后，我开始收到巨大的警告消息：

Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.

我在GitHub论坛上找到了解决方案： https://github.com/aws-amplify/amplify-js/issues/4535#issuecomment-589594827

这使得我的 API 可同步，并且警告消失了：

You could also add this you the transform.conf.json directly:
{ "Version": 5, "ResolverConfig": { "project": { "ConflictHandler": "AUTOMERGE", "ConflictDetection": "VERSION" } } }

下一个问题是，这之前是如何运作的？ ：D

amplify update api
> 
GraphQL
> 进行检查 > 您是否有启用或禁用冲突检测的选项？

amplify push
以确保部署更改，然后运行 
amplify codegen models
在本地重新生成数据存储模型。
