Delete courses
All courses eventually come to an end. The Delete courses link on the administrator's menu is used to permanently delete courses from your Manhattan installation:
You'll probably find that many teachers (and some students) won't want you to immediately delete courses once they are completed. There are a number of ways Manhattan can help you deal with an ever growing number of completed courses:
-
You can use the features described in Changing a course's access rights to mark the completed courses as "no access" or perhaps "read-only". When a course is marked "no access" for students and optionally teachers, the course simply does not appear on their login page. When marked as "read-only", users can view the materials but can not add any new messages.
-
Judicious organization of courses into "groups" can help you as an administrator to know which courses have been completed. Since a course group corresponds to a subdirectory (under the "courses" directory) within your installation, it should be possible to move all of the courses in that group to a separate disk or partition on your server. If those courses are then marked as "read-only" it will then be possible to make one final archive backup of those courses, while they remain live on the server.
-
You should create "course templates" for your teachers (see Create a Course Template for Prof. Einstein), and encourage them to move (using Manhattan's "copy and paste" feature), all learning materials they plan to re-use into the appropriate template. You should never be asked to keep a completed course on the server only because it contains materials like the syllabus or lecture notes a teacher would like to re-use.
The remainder of this section demonstrates how to permanently delete the courses you've created as part of this tutorial. After deleting the courses, you'll delete all of the users you've created, so your Manhattan installation will be back to where it was when you started.
Step 1 - Get a list of courses to choose from
After clicking on the Delete courses link from the administrator's menu, you'll see a search form. This form behaves the same way as the one used when you Configure courses. It essentially asks "Which courses do you want to delete?". Since we want to delete all of the courses created during this tutorial, hold your Ctrl key down as you click on the three available course groups: Templates, try, and clubs. Leave the search box empty to signify you want all of the courses in those groups, then click the Search button:
Step 2 - Select courses from the list
After selecting all of the course groups on the preceding form, you'll be presented with a list of all courses on the server. If you've been following the tutorial, your list will include the courses shown in the screenshot below:
As shown above, check the box next to each course on the list, then click the Delete selected course(s) button at the bottom of the page. You should get a JavaScript prompt asking you to confirm your decision. Click OK.
Step 3 - Confirm your decision
Permanently deleting a Manhattan course is a serious decision. In this step you are again shown a list of the courses you are about to delete, along with a form that requires you to enter your current administrator's password:
Enter your administrator's password and click the button. Answer OK to one last "Are you sure?" prompt and the courses will be permanently deleted from the server. You'll get a listing of the deleted courses and the people who were in them:
