How to get post id in Laravel BEFORE adding it?

Question

Laravel

I want to add an id to the slug, for uniqueness, since the slug is formed from the header, and may already occur. How best to implement? Laravel 5.5

Answer 1

i check the new slug for uniqueness before saving. if non-unique - add time().rand()

Answer 2

Is there any way to check for uniqueness with a validator? It's easier than making crutches.

Answer 3

i make a url()/getUrl() method which will return "{$this->slug}-{$this->id}". store sense in db full slug?

Answer 4

In general, I found this solution:

function getUniqueSlug($model, $slug)
    {
        if ($count = $model::where('slug', 'like', "$slug%")->count()) {
            $slug = str_finish($slug, "-$count");
        }
        return $slug;
    }

Without an id, but that's not bad either) The slug will be unique.
