$-$ you need a working Bootstrap nav bar in a main layout template that allows substituting in sub templates. The nav$-$bar should have $3$ working links.

$-$ the default page associated with the nav$-$bar Home link should just say something like "You have successfully logged in$.$

$-$ when you update the hours worked for a student you need to notify your user that the operation was successful.

$-$ you must display all the employees from a given department and their weekly pay when the View by Department link is clicked.

$-$ your code must allow updating any of the employee's hours worked when the Edit Employee Data link is clicked.

$-$ your code must work with my database, so don't rename anything.
