1.routes：

Route::get('/', 'HomeController@welcome');

Route::auth();

Route::get('/home', 'HomeController@index');

Route::resource('projects', 'ProjectsController');

Route::get('tasks/charts', ['as' => 'tasks.charts', 'uses' => 'TasksController@charts']);
Route::resource('tasks', 'TasksController');

Route::post('tasks/{tasks}/steps/complete', 'StepsController@completeAll');

Route::resource('tasks.steps', 'StepsController');

Route::post('tasks/{id}/check', ['as' => 'tasks.check', 'uses' => 'TasksController@check']);

2.Controller：

namespace AppHttpControllers;

use IlluminateHttpRequest;

use AppHttpRequests;
use AppTask;
use AppStep;
class StepsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return IlluminateHttpResponse
     */
    public function index($id)
    {
        $steps = Task::findOrFail($id)->steps;
        return $steps;
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return IlluminateHttpResponse
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  IlluminateHttpRequest  $request
     * @return IlluminateHttpResponse
     */
    public function store($taskID, Request $request)
    {
        Task::findOrFail($taskID)->steps()->create([
            'name' => $request->name,
            'completed' => 0
            ]);
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return IlluminateHttpResponse
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return IlluminateHttpResponse
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  IlluminateHttpRequest  $request
     * @param  int  $id
     * @return IlluminateHttpResponse
     */
    public function update(Request $request, $taskID, $id)
    {
        $step = Step::findOrFail($id);
        $step->completed = $request->opposite ? 1 : 0;
        $step->save();
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return IlluminateHttpResponse
     */
    public function destroy($taskID, $id)
    {
        Step::findOrFail($id)->delete();
    }

    public function completeAll($taskID)
    {
        Task::findOrFail($taskID)->steps()->update([
            'completed' => 1
            ]);
    }

    public function claerCompeted($taskID)
    {
        Step::where('task_id', $taskID)->where('completed',1)->delete();
    }
}
