Laravel non-object - laravel

Question

I create simple Laravel project. In blog view I have pages index (where is first page of last 5 blogs), Edit, Show, and Create. Now, all working fine if I create new Blog from database (edit/delete and show/read). But I can't create new blog from site. Do you see problem?

* Show the form for creating a new resource.

public function create()
{
return view('blog.create');
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'naslov'=>'Required',
'slug'=>'Required|alpha_dash|min:5|max:255|unique:blogs,slug',
'opis'=>'Required',
'tekst'=>'Required',
'upload_slike' => 'sometimes|image'
]);
$blog = new Blog;
$blog->naslov = $request->naslov;
$blog->slug = $request->slug;
$blog->opis = $request->opis;
$blog->tekst = $request->tekst;
//Sacuvaj novu sliku za blog post
if ($request->hasFile('upload_slike')) {
$image = $request->file('upload_slike');
$filename = time() . '.' . $image->getClientOriginalExtension();
$location = public_path('slike/' . $filename);
Image::make($image)->resize(800, 400)->save($location);
$blog->image = $filename;
}
$blog->save();
return redirect('blog');
}

And this error

Answer 1

The error in the image shows that the error is occurring when you're opening a form tag to delete. Check line 5 in the screenshot you took.
Are you including a delete function on your create screen; perhaps in the extended view layouts.bez-sidebar? If you are then that could be why $blog->id is causing a trying to get property of non object error.
