How to add and remove categories in franzose/ClosureTable for Laravel?

Question

Laravel

Good day!
How to add and remove categories (records) in franzose/ClosureTable for Laravel?
addChild() is when an entry is selected. And if the database does not yet have more than one record, then how to add a new one?
new Model(array(...))->save();- writes to the database, but phpMyAdmin starts to swear when fetching, gives a bunch of errors and the question is whether to ignore them or not.

SQL query

Answer 1

And if the database does not yet have more than one record, then how to add a new one?

$category = new Category([
    'title' => 'News'
]);

$category->makeRoot(0);

UPD: Try this

$category = new Category;
$category->title = 'News';
$category->save();

PS I have used the 1st or 2nd option in some projects. So both options work for me!

Answer 2

is there a step by step guide somewhere for using franzose/ClosureTable for beginners? Apart from the docs on gitHub. To show an example of a controller, model, migration?
