Auto generated IDs

[amugofjava]

I've been reading through the documentation and Quanta looks great. One question I have is on IDs. In the docs, when putting a record the ID is specified. Can Quanta auto generate/auto increment IDs? Thanks.

Hey @amugofjava As of now we don't have auto increment IDs, we create primaryKey and based on that we manage - You can learn more about it in indexManage here

Yes we are already working on auto generate/auto increment IDs, it's in pipeline we will implement this soon, I will update ones it is done.

Thanks for your reply.

@amugofjava I added supports for both manual and automatic ID generation! Here's how it works:

1. Manual IDs (Default):

@QuantaId()
final String id;  // You provide the ID

2. Auto-generated IDs:

@QuantaId(autoGenerate: true)
final String id;  // Empty string will be auto-generated

The auto-generated IDs follow this format:

• Prefix: Entity name in lowercase (e.g., 'user_')
• Timestamp: Current milliseconds since epoch
  Example: user_1647123456789

You can also customize the prefix:

@QuantaId(autoGenerate: true, prefix: 'usr_')
final String id;  // Will generate IDs like: usr_1647123456789

When using auto-generated IDs, just pass an empty string as the ID when creating a new entity:

final user = User(
  id: '',  // Will be auto-generated
  name: 'John',
  email: 'john@example.com'
);

The auto-generation happens automatically during the insert operation, so you don't need to do anything special beyond setting autoGenerate: true in the annotation.

Note: While we don't have traditional auto-incrementing IDs yet, the timestamp-based generation ensures uniqueness. We're planning to add sequential ID generation in a future release.

@amugofjava Thanks for the contribution 😄
