Eloquent Driver - a Statamic Addon

Installation & Usage

You can install and configure the Eloquent Driver using a single command:

php please install:eloquent-driver

The command will install the statamic/eloquent-driver package, publish the config file, then prompt you to select which repositories you wish to move to the database. The command will then publish the relevant migrations and run php artisan migrate behind the scenes.

The command will also give you the opportunity to indicate whether you'd like existing data to be imported.

Importing flat-file content

If you originally opt-out of importing existing content, then later change your mind, you can import existing content by running the relevant commands:

Assets: php please eloquent:import-assets
Blueprints and Fieldsets: php please eloquent:import-blueprints
Collections: php please eloquent:import-collections
Entries: php please eloquent:import-entries
Forms: php please eloquent:import-forms
Globals: php please eloquent:import-globals
Navs: php please eloquent:import-navs
Revisions: php please eloquent:import-revisions
Taxonomies: php please eloquent:import-taxonomies
Sites: php please eloquent:import-sites

Assets

Empty Folders

If your assets are being driven by the Eloquent driver then the database is used as the source of truth for the folder listing, so if no file is present inside a folder then it will not be shown.

Syncing

If your assets are being driven by the Eloquent Driver and you're managing your assets outside of Statamic (eg. directly in the filesystem), you should run the php please eloquent:sync-assets command to add any missing files to the database, and remove files that no longer exist on the filesystem.

Exporting to flat files

If you wish to move back to flat-files, you may use the following commands to export your content out of the database:

Assets: php please eloquent:export-assets
Blueprints and Fieldsets: php please eloquent:export-blueprints
Collections: php please eloquent:export-collections
Entries: php please eloquent:export-entries
Forms: php please eloquent:export-forms
Globals: php please eloquent:export-globals
Navs: php please eloquent:export-navs
Revisions: php please eloquent:export-revisions
Taxonomies: php please eloquent:export-taxonomies
Sites: php please eloquent:export-sites

Configuration

The configuration file, found in config/statamic/eloquent-driver.php is automatically published when you install the Eloquent Driver.

For each of the repositories, it allows you to determine if they should be driven by flat-files (file) or Eloquent (eloquent). Some repositories also have additional options, like the ability to override the model used.

Using dedicated columns for data

Note: This feature is currently only available for Entries.

By default, the Eloquent Driver stores all data in a single data column. However, it is possible to store fields in their own columns.

First, you'll need to enable the map_data_to_columns option in the entries section of the configuration file:

// config/statamic/eloquent-driver.php

'entries' => [
    'driver' => 'file',
    'model' => \Statamic\Eloquent\Entries\EntryModel::class,
    'entry' => \Statamic\Eloquent\Entries\Entry::class,
    'map_data_to_columns' => false,
],

Create a new migration to add the columns to the entries table:
```
php artisan make:migration add_columns_to_entries_table
```
```
public function up()
{
    Schema::create('entries', function (Blueprint $table) {
        $table->string('description')->nullable();
        $table->json('featured_images')->nullable();
    });
}
```
You should ensure that the column names match the field handles in your blueprints. You should also ensure the column type matches that of the fieldtype. As a general rule of thumb, here are some common mappings:

Text fields should be stored as string columns.
Relationship fields should be stored as json columns. (Unless max_items is set to 1, in which case it should be stored as a string column.)
Number fields should be stored as integer or decimal columns.

Run the migration:
```
php artisan migrate
```

If you're adding json or integer columns, you will need to provide your own Entry model in order to set the appropriate casts. You can do this by creating a new model which extends the default Entry model:

<?php

namespace App\Models;

class Entry extends \Statamic\Eloquent\Entries\EntryModel
{
    protected $casts = [
        // The casts from Statamic's base model...
        'date'      => 'datetime',
        'data'      => 'json',
        'published' => 'boolean',

        // Your custom casts...
        'featured_images' => 'json',
    ];
}

If you're using UUIDs as your entry IDs (which is the default if you imported existing entries into the database), you should extend the Statamic\Eloquent\Entries\UuidEntryModel class instead:

class Entry extends \Statamic\Eloquent\Entries\UuidEntryModel

If you have existing entries, you will need to re-save them to populate the new columns. You can do this by pasting the following snippet into php artisan tinker:
```
\Statamic\Facades\Entry::all()->each->save();
```
And that's it! Statamic will now read and write data to the new columns in the entries table, rather than the data column.

Upgrading

After updating to a new version of the Eloquent Driver, please ensure you run php artisan migrate to update your database to the latest schema.

Questions

Can I store users in the database too?

By default, Statamic users live in the users directory of your project. If you wish to move them to the database, please follow this guide.

Can I store some collections in the database, while keeping others in flat-files?

This driver does not make it possible to have some collections flat-file driven and others Eloquent driven. If you're looking for that, you may want to checkout the Runway addon, which is part of The Rad Pack.
