Context

Please refer to these notes before editing this page.

A context is a "space" in Moodle. A context is a space where roles can be assigned. For example, a course, an activity, or a Question bank's question category, are all are contexts. A context might contain other contexts.

There is a hierarchy of contexts which helps locate and define a specific space. A course can have many contexts in its space. These might include lesson, assignment, forum and quiz modules and blocks. Generally speaking, this hieracrhy allows a lower context to receive information from a higher context. Thus a student in the context of Course A, will initially be considered a student in a Quiz context that is located in Course A. Or when I theme has been set for the Biology course categories, that is passed on to Biology 101.

Role and contexts

A context is combined with Role permissions to define a user's capabilities on any page in Moodle. Typically contexts have their own organization structure which allow a user's role to be passed along to the context "below" but not to the one above it.

It is possible to assign a user different permissions based upon a specific context. For example, a user might be given the role of "student" for a course but be given a teacher's role in the context of one specific forum. Or a user can be a teacher of one course and a student in another course.

Many Moodle contexts have a place to grant exceptions to specific roles.

Graphic showing contexts within contexts

The image below shows a few contexts and their relationships. The "System" or Moodle site is the overall context. The user is defined initially in this context.

• The System context has 2 contexts under it, with other context under them
  • The Front page context has
    • An activity module context and
    • A block context within it
  • The Course Cateory context has
    • A Course context within it. The course context has
      • An activity module context and
      • A block context within it
