当我尝试在MongooseModel
上使用Users
时,出现以下错误
嵌套无法解析UserModel(?)的依赖项。请确定 在索引[0]处的参数DatabaseConnection可用于 MongooseModule上下文。

答案 0 :(得分:2)
您应该使用database.provider.ts
导入来代替在MongooseModule.forRootAsync
中静态配置猫鼬:
MongooseModule.forRootAsync({
imports: [ConfigModule],
useFactory: async (configService: ConfigService) => ({
uri: configService.getString('MONGODB_URI'),
useNewUrlParser: true,
useUnifiedTopology: true,
useCreateIndex: true,
useFindAndModify: false,
}),
inject: [ConfigService],
});
