Nit: we should not mix the snake_case with camelCase.

[DanielVZ96]

fixed

[Agrendalath]

Actually, this seems to be a backward-compatible change, so we can revert bumping this version.

[DanielVZ96]

reverted

[Agrendalath]

Nit: can we use a more verbose name for this test, like "test_optional_completion_off_by_default"?

[DanielVZ96]

good idea!

[Agrendalath]

What if the optional_completion is set to False (default), but the parent XBlock has it set to True? In this use case, the field is still active. We should disable this checkbox when ancestor_has_optional_completion returns True, regardless of the xblock_info['optional_completion'] value.

[DanielVZ96]

good point

[Agrendalath]

Regarding this comment about hiding the editor when the completion tracking is not enabled, please see the following parts of code that handle a similar scenario for another editor:

https://github.com/open-craft/edx-platform/blob/a8535ffaeaf44000f46597c7663c950065d0d3eb/cms/templates/base.html#L160

https://github.com/open-craft/edx-platform/blob/42451caa2612a63b42bf5686e6217817e0dd2098/cms/static/js/views/modals/course_outline_modals.js#L1290-L1292

I think we shouldn't move this to a follow-up ticket because this feature is not enabled by default in edx-platform.

[DanielVZ96]

wow i didn't realize it'd be so straight forward. implementing this

[DanielVZ96]

done. I wasn't able to test it manually without hardcoding the value in the base.html. it seems waffle flags are cached somewhere and take quite some time to invalidate the cache.

In case you want to test it and have my same problem you can hard code completion_tracking_enabled to False in cms/templates/base.html line 162.

Suggested change

	<% var message = gettext('Optional %(xblockType)ss won\'t count towards course or parent completion. Only has an effect if completion module is enabled.') %>
	<% var message = gettext('Optional %(xblockType)ss won\'t count towards course or parent completion.') %>

Once we hide the editor when the completion tracking is not enabled, we can remove this part.

[DanielVZ96]

done

[Agrendalath]

@DanielVZ96, the completion tracking should be enabled for the course instead of the section.

Also, you should be able to use something like console.warn(window. course) to verify that it's applied correctly.
