TypeORM是否包含一些功能以避免这种情况:

let contraption = await thingRepository.findOne({ name : "Contraption" });

if(!contraption) // Create if not exist
{
    let newThing = new Thing();
    newThing.name = "Contraption"
    await thingRepository.save(newThing);
    contraption = newThing;
}

就像是 :

let contraption = await thingRepository.upsert({ name : "Contraption" });
