FindOrFail in laravel

Assistant

In Laravel, the `findOrFail()` method is used to retrieve a model by its primary key, and it throws a `ModelNotFoundException` if the model is not found. This is particularly useful when you want to ensure that the model exists and handle cases where it doesn't, instead of returning `null` silently like the `find()` method.

### Example:

use AppModelsUser;

$user = User::findOrFail($id);

– In this example, Laravel will attempt to find the user with the given `$id`. If no user is found, it will throw a `ModelNotFoundException`, which you can catch to handle errors gracefully.

### Handling the Exception:

You can catch the `ModelNotFoundException` to handle the situation where a model is not found.

use AppModelsUser;
use IlluminateDatabaseEloquentModelNotFoundException;

try {
    $user = User::findOrFail($id);
} catch (ModelNotFoundException $e) {
    return response()->json(['error' => 'User not found'], 404);
}

This ensures that if the user is not found, a custom error response is returned.

Inquiries::FindOrFail($id) check if data exxist

Assistant

If you are using `Inquiries::findOrFail($id)` to check if a record exists in the `Inquiries` model, here's how it works:

### Code:

use AppModelsInquiries;

$inquiry = Inquiries::findOrFail($id);

This will:

– Attempt to find an `Inquiries` record with the given `$id`.
– If the record exists, it will return the model instance.
– If the record does **not** exist, it will throw a `ModelNotFoundException`.

### To handle the case when the data doesn't exist:

use AppModelsInquiries;
use IlluminateDatabaseEloquentModelNotFoundException;

try {
    $inquiry = Inquiries::findOrFail($id);
    // Data exists, proceed with your logic
} catch (ModelNotFoundException $e) {
    // Handle the case where the record doesn't exist
    return response()->json(['error' => 'Inquiry not found'], 404);
}

### Explanation:
– If the record with the given `$id` exists, the code will proceed as normal.
– If the record does **not** exist, the `ModelNotFoundException` will be caught, and you can handle it accordingly, such as returning a custom error response.
