Hi there, I am new with rails and html stuff. I have difficulty to understand the differences if I submit a form and refresh the same form, are they doing the same action? For example, I bought some books and then I submit a form of payment. If I refresh it again, would it resubmit a form of payment again? So user will get charge twice? How I can avoid user to resubmit a page with refresh? or how my code can capture what is user doing? refresh the page or submit a form?
