(Beginner) How many parts of my application should know the app-object and is it correct to have mw for every validation?

Hello Slim-fans,
I just want to ask two beginner questions:

1) I'm using my own little MVC pattern right know - I asked myself whether my models (objects like products, users, payments, etc.) should know the Slim's app object. All of them require my database object that is stored within the app-object but for me it feels wrong to give all of those objects access to the entire app-object (that contains configurations etc.).

2) And is it a good practise to have for every form submission a own middleware that validates the input?

Thanks for Slim & thanks for your time
Some regards!

    To answer your first question, no the domain objects within your application should certainly have no knowledge of the application object. Pass the DB instance into the constructor of the objects that need it. Look into dependency injection as a way to do this.

    As for the second one, it's up to you :)

    Hello Rob!
    Thanks for your answer. So how have you solved the second point? What way do you prefer and what should my middleware look like?

    Thanks for your time!!!
    Regards :)
