@Konstruktionsplan you just call the url with blogs/1 and laravel will find the blog with id = 1 (if you set laravel up correctly). This has nothing to do with postman
Okay. Maybe we misunderstand each other or you don't know what Postman is. I would explain it briefly:
Postman is a software with which I can call routes, like from Laravel, with "POST", "GET" etc. This is what you use when you want to test API routes. :)
I need to pass a blog object via Postman to the route blogs/{blog}. The placeholder for this must of course be the blog I want to update.
I have now experimented a little. It works now halfway. I am now trying to make a PUT request, however I am told that "title" and "body" are mandatory. Which is correct, since I require it in the request class as well.
So to understand:
title and body are required
I give via postman the form-data title and body to the update-route with the request PUT.
Still it tells me that it is required. Apparently it can't receive that from postman?
