How to implement autoinc in existing project?

[arso1er]

Hi, I'm using autoinc in a new project and so far, it's working very well. Now, I'd like to use autoinc in an existing project of mine; could you tell me how to apply autoinc to already existing entries in my database?

Thanks.

It's not automated, so you can do this manually:

• Manually set values for your existed records.
• Then define plugin with startAt option: BookSchema.plugin(autoIncrement, { model: 'Book', field: 'bookId', startAt: __YOUR_LAST_NUMBER__ });

PS. will be awesome if somebody makes a PR with helper function for collection, eg. rewriteAutoIncrement(), which traverse all existed records and re-writes ids.

OK, thanks for the answer.
