Presumably, some view function needs to call this handle_ajax function, and return the response as a HttpResponse instance. How does the caller know if this function returned an error message? (If it did, the HttpResponse should have some sort of error status code, rather than 200.) It might be better to have this function raise an exception, which the caller can catch.

If this function will raise Exception, it will be raised in line 594 if module_render.py, so server will generate 500 error. Is it what you want?

Perhaps a new error type should be added to xmodule/exceptions.py to account for invalid requests, which xmodules could raise to indicate that the request is invalid. However, that seems outside the scope of this pull request, and anyway, I don't think we want to spend more time and effort developing xmodules, so it doesn't seem worthwhile. Since xmodule doesn't support what I was looking for, this is fine.

@valera-rozuvan 👍 When Jenkins agrees. |

👍 once the tests pass. You can try rebasing your branch onto the latest master to see if that gets the tests to pass. |
