未找到連接“默認”

Question

錯誤

ConnectionNotFoundError: Connection "default" was not found.

當我開始使用依賴倒置原則時，我收到了這個錯誤。

ormconfig.json

{
  "name": "default",
  "type": "postgres",
  "host": "localhost",
  "port": 5432,
  "username": "postgres",
  "password": "docker",
  "database": "customer",
  "entities": [
    "./src/modules/**/infra/typeorm/entities/*.ts"
  ],
  "migrations": [
    "./src/shared/infra/typeorm/migrations/*.ts"
  ],
  "seeds": [
    "./src/shared/infra/typeorm/seeds/*.ts"
  ],
  "cli": {
    "migrationsDir": "./src/shared/infra/typeorm/migrations"
  }
}

現在列出這個

Column type for Admin#email is not defined and cannot be guessed. Make sure you have turned on an "emitDecoratorMetadata": true option in tsconfig.json. Also make sure you have imported "reflect-metadata" on top of the main entry file in your application (before any entity imported).If you are using JavaScript instead of TypeScript you must explicitly provide a column type.

Answer 1

您必須使用createConnection function 創建與數據庫的連接。

const connection = await createConnection();

createConnection function 返回一個connection 。 將此connection用於所有數據庫操作。
