PR Summary

• Introduction of Department Manager Information
  This update includes a new piece of data, the department_manager, in how we form user profiles.

• Enhancement of User Data Presentation
  In order to accommodate this new information, the layout of our user data table has been adjusted. The department manager details will now be a feature of this table.

• Improved Viewing Experience in User View
  Finally, the user view section has been updated with a new conditional statement in its code. This will allow the department manager data to be visible, adding an extra layer of valuable information to the user interface. This will help users have access to more comprehensive information regarding their department organization.

If a user doesn't have a department, I think this would 500 here.

It wouldn't because of the check in line 502 😄
