Let users submit their own institutional ID. Once submitted, the field is disabled. Allowing no_id option, for other teachers/staffs who are not students, or in cases when some students may be inclined to submit the inst_id later.

Also jump onto new version of Celery.

Things to resolve:

• [x] Django 2.0 drops Py2
• [x] Update install docs: Celery 4 requires a message broker, e.g. redis or rabbitmq

This contributes further towards #631, creating support for non-Python questions.

The current version (c6943a7) adds support for specifying Docker containers, although the default on everything is still Python. Terminology such as runpy has been switched to runcode. The Docker image inducer/relate-runcode-python has been introduced.

Before this change, Relate stores uploaded files in the database, which makes DB dumps (mainly for backups) unwieldy and unpleasant to work with. It likely also needlessly slows down the database. The large (20-ish GB) database dumps are one main reason why running Relate has become an unpleasant chore for me. This is intended to help address that.

With this change, new submissions will be stored in the file system (or, to be technically correct, a configurable Django Storage). Old submissions can be migrated over time with a new management command that this introduces.

I'd be grateful for reviews and testing here, particularly since there's a very real possibility of data loss in case there are issues.

When an answer is submitted to a ShortAnswer question, RELATE will accept the input and grade it correctly. However, the text box disappears, so students cannot see their answer and cannot immediately submit a new answer. To bring the text box back so that they can try again, students must click 'Submit Answer for Feedback', after which RELATE will bring back the text box with the usual error message about not submitting an empty answer.

Under current mechanism, a gopp is created if I test the flow in my account. That will let my student see it in their grade book. Sometimes I don't want student to see some gopp that are supposed to start later (like a month later) and kept answering their question "when should I submit that assignment" or "when can I start that session".

So in this patch, I am using flow_desc to control whether a gopp should be displayed in participant's grade book. I know this patch is somewhat dirty, because the permission added is not for a session, but a gopp. However, the benefit is that I don't need to manually set whether those flows should be display in participants' gradebook. Or, is there a better way to do that?

I saw that #672 had stalled. This is a basic implementation of pytest integration including automatically load the postgres tests if it is connected to a postgres database.

If a user runs pytest, it will run the fast tests, pytest --slow runs the slow tests, and pytest --all runs all tests.

I would recommend migrating to FactoryBoy over the next while since it would replace a lot of the setup/teardown functions and the mixin classes and replace them with native pytest fixtures that allow much easier customization.

If I decorate https://github.com/inducer/relate/blob/63a25b66a45dd2e50dab30124da2a91e4fec14e0/course/utils.py#L845 with course_view, it just failed with 404, not the expected error.

The _is_in_context_manager are unknow to each other in different CoursePageContext instances..

Hello I am having trouble submitting python code from question 8 quiz. I get the following error:

Autograder feedback The grading code failed. Sorry about that. The staff has been informed, and if this problem is due to an issue with the grading code, it will be fixed as soon as possible. In the meantime, you'll see a traceback below that may help you figure out what went wrong.

This is the exception traceback:

I am using a Windows machine (10).

• Bug: this line happened to get passed tests (now it won't).
• Use cache to memorize the git repo path of previously created course, to speed up tests.

Hello,

I wanted to know if it was possible to help me. I followed the instructions from the install page (http://documen.tician.de/relate/misc.html?highlight=css). I keep getting an error (WindowsError: [Error 32] The process cannot access the file because it is being used by another process: u'.....pack....idx'). I have been googling how to rectify this issue but I have been unsuccessful. I am working on a Windows machine. I have python 2.7.6 installed. I look forward to hearing from you soon thank you!
