Error in course discussion because user deletion from Django Admin Page

[Febrian Yuwono]

Hello, I just recently installed open edx with automated installation from this link :

https://openedx.atlassian.net/wiki/display/OpenOPS/Native+Open+edX+Ubuntu+12.04+64+bit+Installation

and i tried creating some users and courses, but when i delete a user with username X from Django Admin Page (openedxURL/admin), and then recreated the username X again (but with different email), I got error when opening the discussion in a course.

The error log are : 

Traceback (most recent call last):

    raise CommentClientRequestError(response.text, response.status_code)

CommentClientRequestError: u'["Username is already taken"]'

When i check the database, I saw that the ID from username X in the SQL was 11, but in the mongo was 6, I believe this is because when I delete the user from django admin panel, the user in mongo was not deleted.

Should i just delete the user in mongo? or are there any other solution?

Thanks,

Hi all,

I have this problem too.

Is there a better way to remove a user?
