Features

Creating Appointment Blocks

• Any role in Canvas that has the ability to manage a course calendar will be able to create & manage Appointment Blocks (role ids configured in application.yml)
  • The ability to create new Appointment Blocks is limited to the active term
• New Appointment Form
  • Location is stored as custom user data in Canvas
    • scope: /signup/location
    • ns: configured in application.yml
  • Calendars are limited to courses in the active term where the user is enrolled as a role with calendar management permissions

Edit Appointment Blocks

• Slot Management
  • New slots can be added, but won't be created until submitting the form
  • Existing slots can be updated/deleted through the Save/Trash icons on the corresponding row

Reserving Appointment Slot

• Calendar managers (ie. Instructors, TAs, etc) can unreserve/reserve slots on behalf of a student or group
• Students can unreserve/reserve on behalf of themselves or their Group
  • Student calendars are validated for both individual and Group reservation (warning will appear)
  • If conflict exists, an option to delete conflicting appointment is displayed

Notifications

• Notifications are managed in the MySQL database
  • When Appointment Block is created, by default all notifications are disabled for the block
• Direct Message
  • Calendar managers can send messages to participants of an Appointment Block
• The email address is retrieved from the user's Canvas profile
• All emails are sent asynchronously

Viewing Participant Summary

• Calendar managers can view a summary of all reservations in the Appointment Block

Deleting Appointment Blocks

• Deleting an Appointment Block will also delete all its slots and existing reservations

Installation

• The tool is installed in the Global Navigation bar
• "LOR External Tools" Feature needs to be enabled for it to appear
• The icon is packaged with the application and retrieved via URL

Limitations

Canvas API Restrictions

• Unpublishing Appointment Groups not allowed
  • Solved by storing published status in MySQL DB, although still visible in Canvas Scheduler
• Updating Calendar
  • Courses & Sections - Removing course/section is not supported by Canvas API, only adding
  • Groups - Changing Group Calendar is not supported by Canvas API
• Participant Visibility
  • Changing from "Not Visible" to "Visible" does not reflect retroactively, only new slots

Notifications from Canvas are still triggered

• Canvas notifications are still triggered by appointment group events. The Canvas user would need to disable their “Scheduling” Notifications

Course Home Calendar Links point to Canvas Scheduler

• Adding custom javascript to Canvas theme is needed to change these links

Instructor can reserve slots on behalf of student/groups

• Student/Group calendars are not validated when an Instructor does this, so conflicts may exist
