Module access 

Who may use a tool on a course: the token’s scopes are checked by dispatch, the teacher’s live roles here, with the course-edit rule the web UI uses.

Functions

authorize_course

The course, if it exists and the user may edit it.

connection

A pooled connection; a busy pool is a retryable error.

deleted_in_staged_changes

The error for a page the user’s staged changes delete.

editable_courses

The courses among courses a user with roles may edit, by the rule of authorize_course.

load_page_facts

The live PageFacts of the course’s pages.

open_course

Authorizes the course argument and loads the course as the user sees it. The connection goes back to the pool before the tool’s own work; handlers that query again take one with connection.

open_course_parts

open_course loading only the parts of the course a tool reads.

page_in_course

The page id argument, checked to belong to the course (as staged or as published).

staged_page_document

The page as staged, a state with the user’s staged changes, has it.

state_of

The state a read asks for.
