Typeorm bulk insert entities with foreign key

Question

I have the following typeorm code in a for loop:

const user = await User.create({
    name: 'bobby',
}).save()
await Post.create({
        title: 'test'
        userId: user.id,
      }).save();

I tried the following code but I get an error about user.id being null:

const user = User.create({
        name: 'bobby',
    })
const post = Post.create({
    title: 'test'
    userId: user.id,
}).save();
await Post.insert(post);
await User.insert(user);

Is there a way to solve this without outright creating a entity new table?

Answer 1

You have to successfully create User before getting its id .

// create new user
const user1 = new User();
user1.name = 'bobby';

// save new user
const userRepo = AppDataSource.getRepository(User);
await userRepo.save(user1);

// create new post
const post1 = new Post();
post1.title = 'test';
post1.userId = user1.id;
// maybe better if you use relation: post1.user = user1;

// save new post
const postRepo = AppDataSource.getRepository(Post);
await postRepo.save(post1);
