Introduction

Since release 1.3, the Themosis framework is bundled with the Illuminate/database package. It provides a performant database query builder as well as the popular Eloquent ORM.

The database guide won't provide a full copy of the official documentation but instead give you notes about possible differences on how things are managed or organized within the Themosis framework.

For detailed information about the database package API, please read the official documentation:

• Laravel database
• Laravel Eloquent ORM

Configuration

The Themosis framework is a WordPress application stack. It is configured to handle a MySQL database connection by default. Database configuration is done inside your application config/database.php configuration file.

You can also define multiple database connections to let your application read/write data from another data source but those connections are not tight with your WordPress instance.

Migrations

Migrations are like version control for your database, allowing anyone on your team to easily modify and share the application's database schema. The Themosis framework is now handling the Laravel schema builder in order to easily build your application's database schema.

The Schema facade provides database agnostic support for creating and manipulating tables accross all supported database systems.

Generate migrations

In order to create a new migration, use the make:migration console command:

php console make:migration create_customers_table

The migration file is placed into the database/migrations directory. See the official documentation for detailed explanation on how to write migrations.

Running migrations

To run all migrations, simply call the migrate console command:

php console migrate

If you use the Homestead virtual machine, make sure to run this command from the virtual machine.

Migration operations may be destructive. In order to protect you from running these commands against your production database, you will be prompted for confirmation before the commands are executed. To force a migration command to run, use the --force flag:

php console migrate --force

Rolling back migrations

All rolling back commands are available though the console but you must take extra care when executing the migrate:fresh command. That command is going to drop all your database tables. As WordPress tables are not yet handled by migrations, executing that command will make you lose all your data.

php console migrate:install
php console migrate:refresh
php console migrate:reset
php console migrate:rollback
php console migrate:status
