Models

Marwa\Framework\Database\Model is the framework-friendly base model built on top of marwa-db ORM. It keeps the upstream ORM behavior, then adds a small layer of convenience methods for common CRUD work such as table access, pagination, attribute normalization, create-or-update flows, and model state inspection.

Use it when you want an application model that feels concise in day-to-day development without hiding the underlying ORM.

What The Framework Model Adds

The base class inherits the core ORM from marwa-db, then adds framework-level helpers such as:

• newQuery() as a clean entry point for query building
• tableName() to read the resolved table name
• useConnection() to switch the model connection
• newInstance() for creating model instances programmatically
• paginate() that returns hydrated model instances
• firstWhere() and findBy() for simple lookups
• firstOrCreate() and updateOrCreate() for common persistence flows
• exists() as an instance check
• forceFill() for bypassing fillable protection deliberately
• syncOriginal(), isDirty(), and isClean() for change tracking
• fresh() for reloading the current record
• saveOrFail() and deleteOrFail() for exception-based writes

That means you still get the ORM model behavior you expect, but the framework layer gives you a more ergonomic API for application code.

Basic Example

<?php

declare(strict_types=1);

namespace App\Models;

use Marwa\Framework\Database\Model;

final class User extends Model
{
    protected static ?string $table = 'users';

    protected static array $fillable = [
        'name',
        'email',
        'active',
        'meta',
    ];

    protected static array $casts = [
        'active' => 'bool',
        'meta' => 'json',
    ];
}

This is the standard pattern:

• set the table when it should not be inferred
• whitelist mass-assignable fields with $fillable
• define casts for attributes that need normalization

Defining Table And Attributes

Table Name

Use $table when you want to be explicit about the backing table:

protected static ?string $table = 'users';

You can also read the resolved table name anywhere with:

User::tableName();

Fillable Fields

Use $fillable to control which attributes may be mass assigned:

protected static array $fillable = [
    'name',
    'email',
    'active',
];

This matters for methods such as create(), fill(), and update() where arrays are applied to the model in bulk.

Attribute Casting

The framework model normalizes input attributes using the model cast map before persistence helpers run.

Supported framework-level normalization in this wrapper includes:

• json and array
• bool
• int
• float

Example:

protected static array $casts = [
    'active' => 'bool',
    'meta' => 'json',
    'login_count' => 'int',
    'score' => 'float',
];

Practical effect:

• bool values are cast to booleans
• int values are cast to integers
• float values are cast to floats
• json and array values are JSON-encoded when arrays or objects are provided

Creating Records

Use create() when you want to insert and return a model in one step:

$user = User::create([
    'name' => 'Alice',
    'email' => 'alice@example.com',
    'active' => true,
    'meta' => ['role' => 'admin'],
]);

You can also create an instance first and save it later:

$user = User::newInstance([
    'name' => 'Bob',
    'email' => 'bob@example.com',
]);

$user->save();

If you want an exception when the write fails, use:

$user->saveOrFail();

Reading Records

For primary-key lookup:

$user = User::find(1);

For a simple column lookup, use findBy() or firstWhere():

$user = User::findBy('email', 'alice@example.com');

$activeUser = User::firstWhere('active', true);

When you need more control, drop into the query builder:

$users = User::newQuery()
    ->where('active', true)
    ->orderBy('name')
    ->get();

newQuery() is just a convenience alias for query(), so use whichever reads better in your codebase.

First-Or-Create And Update-Or-Create

These are useful when your code is driven by unique business keys such as email, slug, or external IDs.

firstOrCreate()

If a matching row exists, it is returned. Otherwise, a new row is created.

$user = User::firstOrCreate(
    ['email' => 'alice@example.com'],
    ['name' => 'Alice', 'active' => true]
);

updateOrCreate()

If a matching row exists, it is updated with the supplied values. Otherwise, a new row is created.

$user = User::updateOrCreate(
    ['email' => 'alice@example.com'],
    ['name' => 'Alice Updated']
);

This pattern is especially useful for sync jobs, import pipelines, and idempotent writes.

Updating Records

Once you have a model instance, update attributes and save:

$user = User::findBy('email', 'alice@example.com');

$user->fill([
    'name' => 'Alice Smith',
]);

$user->save();

Or bypass fillable checks intentionally with forceFill():

$user->forceFill([
    'name' => 'Internal Override',
]);

$user->saveOrFail();

forceFill() is useful for internal framework code, trusted imports, or maintenance jobs where mass-assignment rules should not apply.

Deleting Records

Delete a loaded model in the usual way:

$user = User::find(1);
$user?->delete();

If a failure should raise an exception:

$user->deleteOrFail();

Pagination

The framework wrapper provides a paginate() helper that returns a structured array with hydrated model instances in data.

$page = User::paginate(15, 1);

Returned structure:

[
    'data' => [/* User instances */],
    'total' => 120,
    'per_page' => 15,
    'current_page' => 1,
    'last_page' => 8,
]

Example in a controller:

$users = User::paginate(15, 1);

return $this->view('users/index', [
    'users' => $users['data'],
    'pagination' => $users,
]);

Checking Model State

The framework model includes helpers for understanding whether an instance already exists and whether its attributes have changed.

exists()

Checks whether the model currently has a primary key:

if ($user->exists()) {
    // Existing persisted record
}

isDirty() and isClean()

Use these to detect changes before saving:

if ($user->isDirty('name')) {
    // The name has changed
}

if ($user->isClean()) {
    // Nothing has changed
}

syncOriginal()

If you manually change attributes and want to treat the current state as the new baseline:

$user->syncOriginal();

Refreshing A Model

Use fresh() when you want a new instance reloaded from the database:

$freshUser = $user->fresh();

This is useful after a write when database-level triggers, defaults, or other processes may have changed the stored row.

Switching Connections

If your application uses more than one database connection, you can switch the model class to a named connection:

User::useConnection('reporting');

Use this deliberately. Since it changes the model’s static connection setting, it is best suited to well-bounded application flows.

Practical Example

<?php

declare(strict_types=1);

namespace App\Models;

use Marwa\Framework\Database\Model;

final class User extends Model
{
    protected static ?string $table = 'users';

    protected static array $fillable = [
        'name',
        'email',
        'active',
        'meta',
    ];

    protected static array $casts = [
        'active' => 'bool',
        'meta' => 'json',
    ];
}

Example usage:

$user = User::updateOrCreate(
    ['email' => 'alice@example.com'],
    [
        'name' => 'Alice',
        'active' => true,
        'meta' => ['role' => 'admin'],
    ]
);

if ($user->isDirty()) {
    $user->saveOrFail();
}

$page = User::paginate(10, 1);

Good Practices

• Keep models focused on persistence rules and lightweight domain behavior.
• Use $fillable consistently to avoid accidental mass assignment.
• Prefer findBy() and firstWhere() for straightforward lookups, and newQuery() when conditions become more complex.
• Use updateOrCreate() for idempotent writes instead of open-coded lookup-then-save sequences.
• Use saveOrFail() and deleteOrFail() in flows where silent failure would be a bug.
• Treat forceFill() and useConnection() as deliberate tools, not defaults.
