Any solution? Thanks

[Patrick Samson]

Surprising. Could you report a traceback ?

[Mirza Delic]

I guess you have 'ATOMIC_REQUESTS': True, in the DATABASES of your settings.

If you can live without, the exception should not raise. Anyway I have to find a way to support this feature brought by Dj 1.6. Meanwhile you can safely run Postman without its commit_on_success.

[Mirza Delic]

I removed commit_on_success, but when you fix, please comment here.

[Patrick Samson]

A fix is committed. Compatibility tested with Django 1.5.8 and 1.6.5.

This still occurs with 3.1.0 on Django 1.6.5:

This issue has been fixed after 3.1.0. Sorry, pypi is not up-to-date, you should take the app from here, currently at version 3.2.0a1.

[Former user]

Thanks for the reply. I have updated my pip file.
