Remove the legacy studio updates page and its related artifacts. They
have been replaced by API and a new UI in the authoring MFE.
This cleanup is a part of https://github.com/openedx/edx-platform/issues/36108
BREAKING CHANGE: The 'legacy_studio.updates' waffle flag will no longer
be respected. The system will behave as if the flag is set to false
permanently.
The legacy textbooks page has been replaced with an authoring MFE
equivalent. We don't need to keep the old one around.
This work is part of https://github.com/openedx/edx-platform/issues/36108
BREAKING CHANGE: With this change the `legacy_studio.textbooks` waffle
flag will no longer be respected and the system will behave as if the
flag is always set to False.
This commit implements STUD-1490, allowing creation of components
on the container page. It also enables the delete and duplicate
buttons now that new content can be created that would benefit.
Note that it also creates shared functionality for adding components,
and refactors the unit page to use it too.
These changes implement STUD-813. The commit consists of the
following logical changes:
- a REST API has been implemented for a course's assets
- the page itself now fetches the assets client-side
- the Backbone.Paginator library is used to support pagination
- the AssetCollection has been refactored to extend
Backbone.Paginator.requestPager so that it can be paged
- an abstract PagingView class has been added to generalize
the communication with a paging REST API
- the AssetsView has been reimplemented to extend PagingView
- two new child views have been added:
- PagingHeader: the paging controls above the list of assets
- PagingFooter: the paging controls below the assets
