Introduction to Expertiza

Expertiza is a web application where students can submit and peer-review learning objects (articles, code, web sites, etc). It is used in select courses at NC State and by professors at several other colleges and universities.

Problem Statement

Files involved

admin_controller.rb
views in app/views/admin folder
user_controller

What they do:

The admin controller defines the changes that can be done on other types of users by super-admin and provides the view accordingly.

What needs to be done:

• The text field for adding a new admin/instructor has to be removed, leaving only the button.
• When the button is clicked, it should be redirected to new user creation view making the role (super-admin, admin or instructor) selected as default.
• Make sure that user creation works for super-admin/admin/instructor.
• Associate the users with the institution table
• Add a drop down to the view of creating users so that new account creator can select the institute and save it.
