- Adds the `top_level_parent_usage_key` to the `EntityLinkBase` - This field is used to save the top-level parent of a component or container when it is imported into a course. Example: A unit with components imported into a course. The unit is the top-level parent of the components. - Updates the `DownstreamListView` to return the top-level parents instead of downstream child, if this parent exists. - Each time containers with children were synchronized, a new downstream block was created for each child instead of updating the existing one. This occurred because the `upstream_key` was incorrectly validated as an `Opaquekey` against a list of key strings. This was fixed by converting the `upstream_key` to a string before the verification. (see34cd5a4781and29647831dc) - Which edX user roles will this change impact? "Course Author", "Developer".
CMS
===
This directory contains code relating to the Open edX Content Management System ("CMS"). It allows learning content to be created, edited, versioned, and eventually published to the `Open edX Learning Mangement System <../lms>`_ ("LMS"). The main user-facing application that CMS powers is the `Open edX Studio <https://docs.openedx.org/en/latest/educators/concepts/open_edx_platform/what_is_studio.html>`_
