Contributing database schema changes
Elgg uses Phinx to manage the database migrations.
Create a migration¶
To create a new migration run the following in your console:
phinx create -c engine/conf/migrations.php MigrationClassName
This will generate a timestamped skeleton migration in
engine/schema/migrations/. Follow Phinx documentation to call
the necessary methods to modify the database tables.
Executing a migration¶
Migrations are executed every time your run
upgrade.php. If you would like to execute migrations manually, you can
do so via the command line:
phinx migrate -c engine/conf/migrations.php
Check Phinx documentation for additional flags that allow you to run a single migration or a set of migrations within a time range.
