I want to add a File object into the CustomerForm e.g.
however, in the DB schema I don't want to save the file inside DB, only the file name which is a string input.

1. How can I manage this, since the extend won't work.

2. How do I attach this in the form under EditCustomerform

what do I specifcy in the nameinSchema.
