Laravel找不到控制器方法（不存在）

I'm trying to implement a new method in a BoController called "deleteBooking", the method is defined:

public function deleteBooking($id){
    $booking = Reservation::find($id);
    if($booking && $booking->delete()){
        try {
            $email = Mail::to($booking->user_email)->send(new Cancel($booking));
        } catch(\Exception $e){
            Log::error($e->getMessage());
        }

        return redirect('admin/manager/home')->with('message','Réservation annulée!');
    }
    return redirect('admin/manager/home')->with('message','Réservation non annulée!');
}

But laravel at the endpoint says:

(1/1) BadMethodCallException
Method [deleteBooking] does not exist.

Other methods from the same class are linked to endpoints too, and work well.

Do you have any ideas please? Thank you.

I got it fixed, I've found another file called BoController, in another folder somehow and it was conflicting with the App\Http\Controllers one.

Thank you.

It's most likely that you have declared that function for some other request type other than the one you're trying to make. For example you put Route::post('some-method', 'BoController@deleteBooking'); but you need to put either Route::get(...) or Route::put(...) or Route::delete(...).

If it isn't that problem, then you probably misspelled it.
