DataStore - 订阅错误，连接失败：
DataStore - subscriptionError, Connection failed:
我正在研究 React Native、AWS、DynamoDB、Amplify 项目，并且我正在努力向数据库添加额外的 tables（模型）。
原来的模式非常简单。 （可能太简单了，效果不好）
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精彩瞬间。一切都存储为字符串（出于某种原因...）。
我正在尝试向应用添加更多 table。新的 table 并没有真正连接到当前的 table。唯一连接数据的是 UserID，当用户登录时，我们从“amplify/auth”获得。
我向 schema.graphql 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!]
}
我不想在 DynameDB 中连接 table。我想使用 DataStore 只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();
}
一切正常，直到我尝试添加第二个 table。之后，我开始收到大量警告消息：

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
这使我的 API 可以同步，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，这个之前是怎么做到的？ :D

用户不断捕捉生活中的精彩瞬间。一切都存储为字符串（出于某种原因...）。
我正在尝试向应用添加更多 table。新的 table 并没有真正连接到当前的 table。唯一连接数据的是 UserID，当用户登录时，我们从“amplify/auth”获得。
我向 schema.graphql 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!]
}
我不想在 DynameDB 中连接 table。我想使用 DataStore 只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();
}
一切正常，直到我尝试添加第二个 table。之后，我开始收到大量警告消息：

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
这使我的 API 可以同步，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，这个之前是怎么做到的？ :D
