Right now a message is displayed if the form is valid on post in the UpdateStudent view. This states "Your profile was successfully updated!". This message displays regardless of whether or not information was actually changed: if you hit post without changing anything, this message will still display, but will not be accurate.

Instead of using the form_valid_message attribute in FormView, add logic to the form_valid method to add a message that "your profile was successfully updated" only if there were any changes. If you can think of something else to add if no information was changed that isn't mean (congratulations on hitting the post button, buddy, but you forgot to actually change anything), add that message to the django message queue instead.

I would review other websites, and see what their action is when you submit a form on your profile page without actually updating anything.
