XBlock translations integration with Atlas

i18n service: https://github.com/openedx/edx-platform/blob/4dc35c73ffa6d6a1dcb6e9ea1baa5bed40721125/xmodule/modulestore/django.py#L359-L369

javascript translation urls: https://github.com/Zeit-Labs/xblock-drag-and-drop-v2/blob/master/drag_and_drop_v2/drag_and_drop_v2.py#L318-L332

[Shadi]: how translations will be pulled from Transifix? we said that all local translations in all repos will be removed at the end of the project. This means that somehow the platform must pull translations for each XBlock installed!

Proof of concept PRs:

https://github.com/Zeit-Labs/xblock-drag-and-drop-v2/pull/1
https://github.com/Zeit-Labs/edx-platform/pull/1
https://github.com/openedx/edx-platform/pull/31997
- @shadinaif run ./manage.py lms xblocks_atlas_pull_module in devstack/tutor and it will pull those translations

Practical Test [Shadi]

Preperation

Testing on devstack palm release. With XBlock xblock-drag-and-drop-v2
Applying code on open-release/palm.master.
- Because master branch does work correctly with devstack palm
- https://github.com/Zeit-Labs/edx-platform/pull/2
- https://github.com/Zeit-Labs/xblock-drag-and-drop-v2/pull/2
Commenting out xblock-drag-and-drop-v2==3.1.2 in development.txt requirement file. Because paver update-assets will reinstall the original version within its process if we don’t

First test

i18n service updated
Waffel activated
Translations pulled
XBLOCK_TRANSLATIONS_DIRECTORY correctly set
XBlock OEP-58 support added
XBlock local translations removed

i18n service updated. Installing drag&drop after our i18n fixes and seeing it translating text correctly. Checking in studio container. The XBlock source is in src directory so containers can see it in edx/src

docker-compose exec studio env TERM=xterm-256color bash -c 'pip uninstall --yes xblock-drag-and-drop-v2'
docker-compose exec studio env TERM=xterm-256color bash -c 'rm -Rf /edx/src/xblock-drag-and-drop-v2/build'
docker-compose exec studio env TERM=xterm-256color bash -c 'pip install /edx/src/xblock-drag-and-drop-v2'
docker-compose exec studio env TERM=xterm-256color bash -c 'paver update_assets'
make studio-restart

Works fine, HTML and JS

Second test

i18n service updated
Waffel activated
Translations pulled
XBLOCK_TRANSLATIONS_DIRECTORY correctly set
XBlock OEP-58 support added
XBlock local translations removed

Enabling the waffle switch before pulling anything

Exception!

AttributeError at /course/course-v1:SN+SN2+2023
'ErrorBlockWithMixins' object has no attribute 'raw_grader'
Request Method:	GET
Request URL:	http://localhost:18010/course/course-v1:SN+SN2+2023
Django Version:	3.2.19
Exception Type:	AttributeError
Exception Value:	
'ErrorBlockWithMixins' object has no attribute 'raw_grader'
Exception Location:	/edx/app/edxapp/edx-platform/cms/djangoapps/models/settings/course_grading.py, line 30, in __init__

After tracing the error, it is caused by our code:

File "/edx/app/edxapp/edx-platform/xmodule/modulestore/django.py", line 414, in get_python_locale_directory
xblock_module_name = xblock_resource.__name__
AttributeError: 'str' object has no attribute '__name__'

I fixed it to be:

Now I got an error for missing XBLOCK_TRANSLATIONS_DIRECTORY setting

Added the variable to devstack.py temporarily. Now it is rendering from old translations nicely. The XBLOCK_TRANSLATIONS_DIRECTORY I added is a non-existence directory. Nice!

Third test

i18n service updated
Waffel activated
Translations pulled
XBLOCK_TRANSLATIONS_DIRECTORY correctly set
XBlock OEP-58 support added
XBlock local translations removed

XBlock has atlas support and still has the original local translation

Result: Same problem in the Second test,,,,, fixed the same way

Working fine, still loading local translations

Fourth test

i18n service updated
Waffel activated
Translations pulled
XBLOCK_TRANSLATIONS_DIRECTORY correctly set
XBlock OEP-58 support added
XBlock local translations removed

Pulling translations: pulled successfully. But not compiled

Running cd conf && i18n_tool generate , compiled successfully. But before compilation, I changed few translations of Arabic language so I can see if translations are pulled from local or OEP-58 directory without setting annoying logs

No JS compilation made so far!

Python translation didn’t read from atlas directory. Expected since XBLOCK_TRANSLATIONS_DIRECTORY is not set correctly

Fifth test

i18n service updated
Waffel activated
Translations pulled
XBLOCK_TRANSLATIONS_DIRECTORY correctly set
XBlock OEP-58 support added
XBlock local translations removed

Still doesn’t read from Atlas directory! checking…

Error loading the translation directory

First issue, my fix in Second Test is not correct, because it is damaged legacy loading. Reverting and then updating:

Second issue: the domain for translation is set to text , I had to rename it to django. But this will damage backward compatibility, this must be encapsulated in a check for the waffle, or better to pull block translations into text.po instead of django.po
Third issue, the result of xblock_module_name is drag_and_drop_v2.drag_and_drop_v2 while the translation is in drag_and_drop_v2

After manually changing the directory name pulled by Atlas, translations for Django Templates read from Atlas successfully

Java Script translations are not loaded from Atlas yet! The text.js does not exist yet

Pending Known Issues

Module Name

Module name that we calculate with

raises an error because xblock_resource is a string. Using xblock_resource itself does not return the desired name that is used by Atlas when pulling translations. We need to unify the name between the two mechanisms

Domain

The domain used in the XBlock is still text (and it should still be that in my opinion). But the translation is being pulled as django

Python Compilation

Atlas command should compile translations after pulling them

JS translation not being compiled

This mechanism is not implemented yet
