Database log in Laravel 5.4?

Question

I caught a project in progress but still do not know very well the Laravel, and I’m trying to save the data in the database using this code in controller:

public function store(Request $request)
{
    $validator = \Validator::make($request->all(), [
        'name' => 'required',
        'description' => 'required',
        'coverage' => 'required',

    ]);

    if($validator->fails()) {
        flash($validator->errors)->error();
        return view('projects.create');
    }

    try {
        $project = $this->repository->store($request->all());
        flash('O projeto '. $project->name .' foi criado com sucesso!')->success();
        return redirect()->route('projects.show', ['id'=> $project->id]);
    } catch (\Exception $e) {
        flash($e->getMessage())->error();
        return view('projects.create');
    }
    dd($request);
}

when trying to log the data by the site I get the following error:

(2/2) Errorexception Undefined variable: Components (View: C: xampp htdocs thermopeu Resources views Projects create.blade.php)

it seems silly thing but I’m not getting past it, the database is already working, including entering a project manually by phpMyAdmin and do the view from that project to the user.

What can I do to fix this?

Below follows the view as requested. It’s a bit large, note that the component should be picked up by the "side-bar":

Inside the create.Blade view it expects a variable called Components that you are not sending in Exception or Validator fail. And your Insert is wrong the right would be so:

 $project = Project::create($request->all());
