How do I lock course objects in a blueprint course as an instructor?

If you are enrolled in a blueprint course as an instructor, you can lock and unlock course objects and sync content for the blueprint course. Depending on your admin's preference, locked objects may include attributes for content, points, due dates, and availability dates. Attributes may apply to some or all object types: assignments, discussions, pages, files, and quizzes.

If you are not sure how objects are defined for the course, you can view locked attributes by viewing an individual object. Attributes for locked objects may be changed by an admin in the blueprint at any time.

Locked Objects

Locking an object in a course enforces the attributes defined by your Canvas admin. Any change to an attribute retroactively applies to all locked objects in the associated course. If an attribute is enabled for locked objects in the blueprint course, any locked attributes in the associated course that vary from locked attributes in the blueprint course will trigger unsynced changes in the blueprint course and override the associated course objects.

Locking or unlocking an object applies immediately to all associated courses. However, the change will still be noted as an unsynced change and will not appear in the Sync History page until the sync is complete. Additionally, changes are not identified as an unsynced change until the page is refreshed. 

Unlocked Objects

Objects that are unlocked can be managed by a course instructor in the associated course like any other Canvas object. If the blueprint course is synced and the instructor has modified unlocked objects in the associated course, unlocked objects are not overwritten with the synced changes.

Unlocked blueprint objects can be locked at any time. If you lock an unpublished object, and that object was previously removed from an associated course, the object will be replaced in the associated course.

Object Management

This article shows how to lock an object from the Assignments page. Objects can also be managed in the Files, Modules, Pages, and Quizzes pages.

In Modules, only individual module items can be locked. Changes to the modules structure are triggered as part of a course sync.

Note: You can only lock and unlock objects created in the blueprint course. Any new objects added to an associated course by an instructor does not include a blueprint icon and is not associated with the blueprint course.

Instructors in an associated course can view locked and unlocked icons in the Index page. However, they cannot manage the existing status of an object.

For locked objects, the individual page displays the locked attributes selected in Course Settings, if any. Instructors in associated courses cannot modify locked objects, so any attributes that are locked cannot be edited.
