Try: @PrimaryGeneratedColumn(“uuid”) id: string; Also, if you don’t need a primary column, but need to generate uuid sequence, you can try this: @Column() @Generated(“uuid”) uuid: string;

If you’re receiving this error, you probably need to update your rxjs dependency to >7. npm i rxjs@^7 yarn add rxjs@^7 pnpm i rxjs @^7 Pick your flavor of … Read more
As of TypeORM version 0.3.0 you can do the following: repository.find({ order: { singer: { name: “ASC” } } }) Before version 0.3.0 (original response) I don’t think it is currently supported by typeorm without the query builder, there is currently a feature request open With the QueryBuilder it is quite simple though: connection.createQueryBuilder(Song, ‘songs’) … Read more
We can load sub-relations by using ‘relation.subrelation’ within the relations array itself like this: relations: [‘relation1’, ‘relation2’, ‘relation2.subrelation1’] So for your case, instead of using join you can simply do something like this: this.entityManager.findOne(ChatRoomEntity, { where: {id: roomToJoin.id}, relations: [‘activeUsers’, ‘messages’, ‘messages.fromUser’], }).then(roomEntity => { … This is specified here: https://github.com/typeorm/typeorm/blob/master/docs/find-options.md#basic-options
