Code cannot be saved in the webpage about tie HOT 8 CLOSED

Definitely an issue we've had -- how would you propose fixing this?

Can we use cookie to do this, since we don't have concept of server and session? @eyurko

Can we just let chrome or any other browser to cache the code?

Thank you for reply! I do not have specific details yet but the basic two ideas is to use backend database or web cookie. Thanks! @eyurko

@luofei11 we do keep some concept of a session -- check the TranscriptObjectFactory / SnapshotObjectFactory.

Also, this is a duplicate of #54.

Copying comments from #54 and closing it since this thread seems to have progressed farther. Noting @eyurko's comment from there, too:

Generally, we'd like to be able to preserve student code on a problem if they navigate between questions or if they refresh the page, but we preprocess the code before saving it in CodeEvalResult. This suggests that it would be worth saving the unprocessed, raw student code as part of the snapshot as well, otherwise we'd have to reverse the preprocess step, which would be needlessly expensive.

My suggestion would be to use localStorage/sessionStorage, since we don't have a backend database. I recommend coming up with a brief technical description of the proposed solution (what namespace are you going to use, for example) before trying to implement it.

@seanlip I would suggest using localStorage as it stores data with no expiration date.

@seanlip Can you please assign me this issue or add me to the collaborator since I am working with Kaikai @sniffsky on this issue together.
