Roles and permissions
Please refer to these notes before editing this page.
Roles and capabilities in Moodle 1.7 onwards provides great flexibility in managing how users interact. Prior to Moodle 1.7, there were only six roles possible: guest, student, non-editing teacher, editing teacher, course creator, and administrator. Whilst these roles may still be used, it's now possible to create additional roles, and to change what a given role can do in a particular activity.
- An identifier of the user's status. The status depends upon permissions given for one or more capabilities in a context.
- For example Teacher and Student are standard user roles. The identifier indicates they probably have different capabilities in some contexts.
- When Moodle is first installed, a number of Standard roles are created automatically.
- A description of a particular Moodle feature. A list of many capabilities can be seen in the capability category index page.
- For example moodle/blog:create(writing blog entries) or "Backup course" are two capabilities. Note the "mod/blog:create" notation is a common to identify a capability.
- A setting for a capability. Can be any one of four: not set/inherit, allow, prevent or prohibit.
- A "space" in Moodle.
- For example: a course, activity module or block can each be a context.
- Some contexts can contain multiple contexts in their space, For example, a course can contain a lesson, assignment, forum and quiz modules, plus blocks.
