Resolving a BadMethodCallException for an undefined method like restore in Laravel typically involves ensuring the model uses the SoftDeletes trait and that you are calling the static method on the correct class instance. This error often stems from missing imports, incorrect usage of static versus instance methods, or outdated package versions that do not support the specific API call being made.
Understanding the SoftDeletes Trait
The primary reason developers encounter this exception when calling
restore() is the absence of the
Illuminate\Database\Eloquent\SoftDeletes trait in their model definition. In Laravel, soft deleting does not remove records from the database; instead, it sets a
deleted_at timestamp. To reverse this action using
restore(), the model must explicitly declare that it supports soft deletion. Without this trait, the Eloquent ORM has no knowledge of the restoration logic, leading to the "undefined method" error because the method simply does not exist on the base Model class.
To fix this, open your model file, such as
app/Models/ExampleModel.php, and ensure the trait is imported at the top of the file. Then, add the trait to the list of traits used by the class. The structure should look like this:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class ExampleModel extends Model
{
use SoftDeletes;
protected $dates = ['deleted_at'];
}
By including
use SoftDeletes;, Laravel automatically adds several methods to your model, including
forceDelete(),
restore(), and
withTrashed(). If you have recently added soft deletes to an existing application, remember that you must also run a migration to add the
deleted_at column to your database table. Failure to migrate the schema will result in SQL errors rather than PHP exceptions, but both issues prevent proper data management.
Static vs Instance Method Usage
A common source of confusion is how
restore() is invoked. While you can restore a single deleted model instance by calling the method on that object, the more frequent pattern involves restoring multiple models via a query builder scope. If you attempt to call
ExampleModel::restore() directly on the class without a preceding query scope, Laravel may throw an exception because the static method is not defined in the standard way.
Instead of calling the method statically on the model class, you should use the query builder to filter the records you wish to restore. For example, to restore all users who were deleted more than 30 days ago, you would construct a query that scopes the results to trashed items and then applies the restoration.
use App\Models\ExampleModel;
// Restore specific instances
$trashedUser = ExampleModel::withTrashed()->find($id);
if ($trashedUser) {
$trashedUser->restore();
}
// Restore via query builder
ExampleModel::onlyTrashed()
->where('deleted_at', '<', now()->subDays(30))
->restore();
When using the query builder approach with
onlyTrashed(), the
restore() method acts on the query itself, updating all matching records in the database. This is significantly more efficient than retrieving each model individually and calling the method in a loop. Ensure you are not mixing up the syntax, as
ExampleModel::restore() without a scope is invalid unless you have manually overridden the magic method handling in your model, which is rarely necessary.
Autoload and Caching Issues
Sometimes the code is correct, but the application fails to recognize the new methods due to caching mechanisms. Laravel caches various configuration files and route definitions to improve performance. If you have just added the
SoftDeletes trait or modified the model structure, these changes might not be reflected immediately in the running application.
Clearing the configuration cache is a critical step in troubleshooting this issue. Run the following command in your terminal to flush the cached configurations:
php artisan config:clear
Additionally, if you are using OPcache or other PHP-level caches, restarting the PHP-FPM service or the web server may be required. In development environments, ensuring that
APP_DEBUG=true in your
.env file provides more detailed error messages, which can help pinpoint if the issue is related to the trait loading or a different underlying problem. It is also good practice to run
composer dump-autoload after making significant changes to namespace structures or adding new classes to ensure the autoloader is up to date.

Version Compatibility Checks
Ensure that your Laravel version supports the features you are attempting to use. The
SoftDeletes trait has been part of Laravel since version 5.0, so version compatibility is rarely the cause of this specific exception in modern projects. However, if you are working with a legacy project or a forked version of Laravel, verify that the core framework files have not been corrupted or modified.
Checking your composer.json file confirms the installed version. If you are upgrading from a very old version, review the upgrade guide for any breaking changes regarding Eloquent behavior. In most cases, however, this error is purely syntactical or structural within your own model definition rather than a framework limitation.
Frequently Asked Questions
Why does my model still show as deleted after calling restore?
If the record remains marked as deleted, check that the
deleted_at column in your database is actually being updated to NULL. Sometimes, manual database interventions or race conditions during concurrent requests can leave the timestamp intact. Verify the database state directly using a SQL client to see if the value persists.
Can I restore a model without using the SoftDeletes trait?
No, the
restore() method is specifically generated by the
SoftDeletes trait. Without it, the method does not exist on the model class. You would need to manually write a custom method to update the
deleted_at column to NULL, but this bypasses the standard Eloquent lifecycle hooks provided by the framework.
What is the difference between restore() and forceDelete()?
restore() reverses a soft delete by setting
deleted_at to NULL, keeping the record in the database.
forceDelete() permanently removes the record from the database using a standard DELETE query. Use
forceDelete() only when you intend to irreversibly remove the data.
How do I include restored models in my queries again?
By default, queries exclude soft-deleted records. After restoring a model, it becomes visible in standard queries again. If you want to explicitly fetch both active and deleted records, use the
withTrashed() scope. This ensures your application logic accounts for the full history of the entity.
Does restoring a model trigger events?
Yes, restoring a soft-deleted model triggers the
restored event. You can listen to this event in your EventServiceProvider or using listeners to perform side effects, such as sending notifications or updating related statistics. This allows you to maintain consistency across your application state when data is reactivated.
