Leaf Schema

Schema files are a new way to define and manage your database structure in Leaf applications. Instead of writing complex migration files using PHP, and then managing multiple migrations for a single database table, you can now define a simplified structure using yml and let Leaf handle the rest.

This module packages the schema functionality into a standalone package which can be used in any PHP application once the port is complete.

If you use Leaf MVC, this is already included and configured for you.

To get started, install the schema module:

Once installed, you can start creating your schema files using the g:schema command:

Schema Files

Schema Files allow you to define your database tables, seed data, and keep track of your database automatically in one simple YAML file. They are clean, readable, and designed to help you move fast without the overhead. Every schema file is tied to a table in your database, for example, if you create a schema file called flights, it will be tied to the flights table in your database.

We can do this by running the command below:

This will create a new file in the database directory called flights.yml. You can open this file and start defining your table structure.

In this example, we have defined a table with three columns: to, from, and identifier, which are all of type string in this case, but can be any valid column type. You can view a full list of column types in the documentation.

Migrating Schema Files

Once you have defined your schema file, you can create the table in your database by running the migrate command:

This command will read all the schema files in the database directory and create the corresponding tables in your database. If the table already exists, it will update the table structure to match the schema file. You can also migrate a specific schema file by passing the name of the file as an argument:

Syncing Changes

The major difference between schema files and traditional migrations is that you don't have to create a new migration file every time you want to make a change to your table structure. Instead, you can simply update the schema file and run the migrate command again. Leaf will automatically detect the changes and apply them to the database if it is aware of the previous state of the table.

Other commands

You can perform other operations on your schema files like rolling back changes, refreshing the database, and seeding data. We recommend checking out the documentation for the full documentation on schema files and all the available commands.
