PHP Luminova: Database Seeding and Migration Version Control

The Database Version Control uses db:clear command to manage and clean up lock files and old migration or seeder files.This command helps maintain a clean working environment by removing unnecessary files that can clutter the system or cause conflicts during development and deployment processes.

Clearing Migration or Seeder Lock Files

Seeder or Migration lock files are created to track the state of executions. Over time, these lock files can accumulate, become unnecessary and may need to be cleared. The --lock=[context] option removes all specific context lock files from the system.

Clearing Specific Lock Files

If you need to clear lock files for a specific migration or seeder class, use the --class option in combination with the --lock=[context] option.This targets only the lock files associated with the specified class, allowing for more control.

Removing Old Files

While the primary purpose of db:clear is to manage lock files, it also addresses the removal of old migration and seeder files.When lock files are cleared, the associated old files are also removed if they are no longer referenced in the lock files.This helps to ensure that the file system remains clean and free of obsolete files.

Command Description

The db:clear command clears lock files for seeders or migrations.Additionally, it can remove old migration and seeder files based on the specified options.This is particularly useful for cleaning up after testing or when certain migrations or seeders are no longer needed.
