Laravel missing required parameters on destroy route - php

Question

I've just created a new project something like todo list in Laravel. When I try to do simple deleting I get this error:
Missing required parameters for [Route: destroy] [URI: {}]. (View: C:...\resources\views\index.blade.php)
Here is part of code from index.blade.php:
#if($todos)
<ol>
#foreach($todos as $todo)
<li>{{ $todo->todo }}</li>
<form action="" method="post">
#csrf
#method('Delete')
x
</form>
#endforeach
</ol>
#endif
so I am just checking if there is anything, if not, then don't show list.
Part of code from controller:
public function index()
{
$todos = Todo::all();
return view('index', ['todos' => $todos]);
}
public function destroy($id)
{
Todo::findOrFail($id)->delete();
}
and line of code from web.php:
Route::resource('/', 'TodosController');
This is so basic and it is making me crazy because I can't figure out what is causing this error. Seems like everything is good.

Answer 1

Im not 100% certain, but try updating your resource route declaration to:
Route::resource('todos', 'TodosController');
and changing your link to
x
In the docs here, https://laravel.com/docs/5.7/controllers#restful-naming-resource-route-parameters
They describe the routes as being created like:
Actions Handled By Resource Controller
DELETE /photos/{photo} destroy photos.destroy

Answer 2

You don't actually submit your form. You just click on a link, so you in essence make a GET request, and not a POST request.
You need to send it through a form.
#foreach($todos as $todo)
<li>{{ $todo->todo }}</li>
<form action="{{ route('destroy', $todo->id) }}" method="POST">
#csrf
#method('DELETE')
<input type="submit" class="btn btn-danger" value="x" />
</form>
#endforeach
Having an inline form like that can appear a bit weird, so you can instead put the button outside, and submit your form on click.
#foreach($todos as $todo)
<li>
{{ $todo->todo }}
<a href="#" class="btn btn-danger"
onclick="event.preventDefault();
document.getElementById('todo-destroy-{{ $todo->id }}').submit();">x</a>
</li>
<form action="{{ route('destroy', $todo->id) }}" method="POST" id="todo-destroy-{{ $todo->id }}">
#csrf
#method('DELETE')
</form>
#endforeach
