Laravel - find by custom column or fail

Question

There's findOrFail() method which throws 404 if nothing was found, e.g.:

User::findOrFail(1);

How can I find an entity by custom column or fail, something like this:

Page::findBySlugOrFail('about');

Answer 1

It took at least two hours to realize that if you chain firstOrFail() method after where() in Laravel 5.6, it basically tries to retrieve the first record of the table and removes where clauses. So call firstOrFail before where.

Model::firstOrFail()->where('something', $value)

Answer 2

Try it like this:

Page::where('slug', '=', 'about')->firstOrFail();
