45,636 PointsI am stuck in the "Accessing our Relationships" of the course Laravel Basics
I am following the course with Laravel 5.
I got a error "BadMethodCallException in Builder.php line 2024: Call to undefined method Illuminate\Database\Query\Builder::listItems()"
I created the Model "TodoItem" as the course goes. I placed the "use App\TodoItem;" in TodoListController.php.
I can't solve this error. please help me figure it out.

45,636 PointsHello.
It's TodoItem.php in app folder
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class TodoItem extends Model { public function todoList() { return $this->belongTo("App\TodoList"); } }
It's TodoListController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests; use App\TodoList; use App\TodoItem; use App\Http\Controllers\Controller; use Illuminate\Support\Facades\Validator;
class TodoListController extends Controller { /** * Display the specified resource. * * @param int $id * @return Response */ public function show($id) { $list = TodoList::findOrFail($id); $items = $list->listItems()->get(); return $items; return view("todos.show")->withList($list); }
It's my codes. Could you find the problems in my codes?

9,453 PointsHello,
Can you post the contents of your TodoList model? Call to undefined method usually means you are trying to use a function that you have not yet created.
It looks like your TodoList model should have a function as such:
public function listItems()
{
return $this->hasMany('App\ToDoItem');
}

45,636 PointsNow I am moving to Nested CRUD with Laravel.
If you can, can you help me solve a problem?
I got a error "InvalidArgumentException in Response.php line 470: The HTTP status code "1" is not valid." in the "Nested Updates". When I update item in " TodoItems".
even though I got a error, todo_items was updated well. I don't know why I got a error. it's my code "TodoItemController.php"
public function update(Request $request, $list_id, $item_id)
{
$rules = array(
"content" => array("required")
);
$validator = Validator::make($request->all(), $rules);
if($validator->fails()) {
return redirect("todos/items/edit", [$list_id, $item_id])->withErrors($validator)->withInput();
}
$item = TodoItem::findOrFail($item_id);
$item->content = $request->input("content");
$item->Update();
return redirect("todos.show", [$list_id])
->withMessage("item was updateed");
}

9,453 PointsSure I would love to. If you could please make a new question (that way someone else can potentially find the answer in the future if they need it) with your controller method and the route entry that points to this controller.
I have an idea about what the issue is but I would like to see the route first.
