Hi Jani, thanks for making it clear. [image: smile.png] Actually I would like to assign a lot of images to a product and only have one image as the default image. How would you do this? Can you give me a hint? Am Montag, 17. November 2014 11:25:37 UTC+1 schrieb Jani Tiainen: > > On Sun, 16

Alternative to fabric

Hi all, We are just about ready to release our newly rewritten website. It is based on Django 1.6 and Python 3. We have worked through all of the problems with using python 3 (migrated some plugins ourselves, other plugins were updated during the course of the project). The only problem we have

Re: Runtime warning about a naive datetime when running the test command

Hi Daniel. The problem is you're probably generating a naive datetime at some point in your code. The best way to solve this is to run the tests with $ python -W error manage.py test That way an exception will be raised instead of a warning. From there you can probably figure out where it is

Hi Andreas, If you like fabric, why not just use Python 3 for your project and Python 2 for fabric? You can easily have multiple Python interpreters installed. Just install Python 2 to a path like ~/local and give fabric its own virtualenv. Best regards, René On Monday 17 November 2014

Hi René, I saw that kind of solution. The only thing is I really didn't like having to setup 2 environments, but perhaps that is the way to go. I will however be looking into ansible, to see if that is an alternative (I know that it runs python 2 as well, but I liked the format of it). Regards,

You'd better have a look at the raw database SQL. I think syncdb won't change the null attr of this column if it is not set in the first time. So the possible solutions are 1) change the column in db manually 2) use a migration tool like south. Hope this can help you. -- You received this
