Auto role assignment block
Automation of role assignment process will enable permission managing for momentary cases and on “by user” basis. The main idea is to enable the system to reassign roles of participants based on actions they undertake. For example: the student passing the test is denied any communication options, but retains them upon completion. This approach would require significant effort from administrator with current manual-only role and permission management system.
Rule structure
Rule changes the permissions of the user depending on the event in the system.
Rules structure:
Required parameters:
- Name of rule;
- Type of rule;
- A role that will be assigned to the user when the rule will trigger;
- Roles that are permitted a transition;
- Elements of the course for which the rule is triggered.
Optional parameters may be added depending on the type of rule.
Block appearance
The block contains three links:
- Link to add rule page
- Link to current rules page
- Link to active rules page
- Current role of user in course
Add rule page
