SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: 'column_name' in Laravel
null is different than not existend. If you want to set null as a value you have to write it in your query:
... ('2016-12-06 06:56:01',27, null, '2016-12-06 06:56:01'))Also the datetime format is wrong. You have to enter it as a string.
Set 0 for unit_id before query, if it null/empty. See example:
if(!isset($unit_id) || empty($unit_id)) $unit_id = 0;..//insert query rest code
Just had the same issue and in my case it was a silly mistake in my controller.
What I did was I returned the whole object instead of just the id, like so:
public function store($id, Request $request) { $post = Post::find($id); $comment = new Comment; $comment->text = $request->comment; $comment->post_id = $post; <--- HERE IS THE MISTAKE $comment->post_id = $post->id; <--- HERE IS THE FIX $comment->user_id = Auth::id(); $comment->save(); return back(); }
