wheels dbmigrate up

Run the next pending database migration.

Synopsis

wheels dbmigrate up

Alias: wheels db up

Description

The dbmigrate up command executes the next pending migration in your database migration queue. This command is used to incrementally apply database changes one migration at a time, allowing for controlled and reversible database schema updates.

Parameters

None.

Examples

Run the next pending migration

wheels dbmigrate up

This will execute the next migration in the sequence and update the database schema version.

Use Cases

Incremental Database Updates

When you want to apply database changes one at a time rather than all at once:

# Check pending migrations
wheels dbmigrate info

# Apply next migration
wheels dbmigrate up

# Verify the change
wheels dbmigrate info

Controlled Migration Application

Apply migrations one at a time for better control:

# Check current status
wheels dbmigrate info

# Apply next migration
wheels dbmigrate up

# Verify the change was applied
wheels dbmigrate info

Notes

• Migrations are executed in chronological order based on their timestamps

• Each migration is tracked in the database to prevent duplicate execution

• If already at latest version, displays: "We're all up to date already!"

• If no more versions available, displays: "No more versions to go to?"

• Automatically runs dbmigrate info after successful migration

• Always backup your database before running migrations in production
