Does not work in python3

[guziy]

when trying to execute the following

./manage.py migrate slideshow

I get the error messages below:

A OK, I see that it is not supposed to ))

Well, a python3 version wouldn't hurt of course. I'm too busy right now to do anything about it, but if you want, don't hesitate to file a Pull Request.

Actually the problem is in the 2 packages slideshow depends on:

• adminsortable

Running django-admin-sortable-1.6.7/setup.py -q bdist_egg --dist-dir /var/folders/2w/9n_4bv2x2cx2mq1z8ds10kkw0000gn/T/easy_install-raozn_1d/django-admin-sortable-1.6.7/egg-dist-tmp-ve76vm95

                     ^

• easy_thumbnails

 SyntaxError: Missing parentheses in call to 'print'

I get these exceptions when after doing pip install djangocms-slideshow (when it tries to satisfy dependencies). What is interesting is that even with those errors pip list shows those packages as installed...

And I also did not find any code in the slideshow plugin that would not work in python3.

I'll try look at the 2 plugins and test the slideshow in python3, when I can find some time...

Cheers

I have just found out a cool way to see if python3 could be used (though it does not detect the problem with easy_thumbnails):

$ python setup.py caniusepython3
running caniusepython3
Finding and checking dependencies ...
[WARNING] Stale overrides: {'djangocms-admin-style', 'unicodecsv', 'bcdoc'}

You need 1 project to transition to Python 3.
Of that 1 project, 1 has no direct dependencies blocking its transition:

  django-admin-sortable

Interesting, I did not know about the caniusepython3 tool. I'll re-open the issue as a reminder.
