UUID type for mongo id

[waynehaffenden]

I'm looking at using UUID v4 as the IDs for all the collections/models in Mongo, any ideas on how I do this?

next time, please directly use github discussions

if you mean v4 from uuid, then you can easily do this by setting your type to String:

class Test {
  @prop({ type: () => String, required: true })
  public _id!: string;
}
// Because you are re-defining the "_id" property, you cannot use ObjectId's anymore (or anything that requires it), also, as long as option "default" is not set, you have to provide the "_id" property every time you create a document

Also, if you weren't already aware, if you generate your own IDs, then you will be responsible for setting them everywhere they need to be set (i.e. creation/ saving new docs). Mongoose takes care of this for you, if you use the standard ObjectIds.

@hasezoey Thank you, I'll do this in future :)

@smolinari Is there no way of doing this automatically, like the default property on mongoose schema object but in typegoose?

actually what @smolinari wrote, i had already in the code example as a comment (look above)
TL;DR: unless you set PropOption default, you have to always provide _id

also, i would recommend you use validate to validate that your id's are only uuid (not some random string)

Haha.. I didn't read that comment. 😊
