Database

The user is asking for clarification on how adding attributes to a database affects previous documents. They are also concerned about adding new features to their app that require new attributes, and experiencing issues that can only be resolved by resetting everything. They are unsure how to handle this in a production app. Solution: When adding attributes to a database, previous documents will be null unless the attribute is added as a list. To avoid issues when adding new features and attributes to an app in production, you can use database migration techniques. This allows you to make changes to the database schema without losing existing data.
