In Laravel, you can validate model object instances by utilizing Laravel's built-in validation feature. Here's a step-by-step guide on how to validate a model object instance in Laravel:
- Define the validation rules for the model object in a separate class or directly in the controller method. For example, you can define the rules in a separate Request class:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
class MyModelRequest extends FormRequest
{
public function rules()
{
return [
'name' => 'required|string|max:255',
'email' => 'required|email',
// Add more rules as needed
];
}
}
|
- In your controller method, you can validate the model object instance using the defined validation rules. You can access the model object's attributes using the ->attributes property. For example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
use AppHttpRequestsMyModelRequest;
public function store(MyModelRequest $request)
{
$model = new MyModel();
$model->fill($request->validated());
// Validate the model object instance
$request->validate();
// Save the model object instance
$model->save();
return response()->json($model, 201);
}
|
- If the validation fails, Laravel will automatically redirect the user back with the validation errors. You can display the errors in the view using the @error directive. For example:
1 2 3 4 5 6 7 8 9 |
@if ($errors->any())
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
|
By following these steps, you can easily validate model object instances in Laravel using Laravel's built-in validation feature.
