My colleague started a django project on Ubuntu. I want to run the same project on OS X Yosemite. We both use python3.4 and following packages:
Django (1.8.2)
Pillow (2.8.1)
pip (7.0.3)
setuptools (17.0)
wheel (0.24.0)
And we both run project in virtual env.
When I cloned project, I used
python manage.py syncdb
And I got following results:

I have no idea why this happens and used several methods described in this site and other sites.
What happened and why?
This should have thrown an error on your Ubuntu install as well.
You need to change line 3 of projectName/main/admin.py to:
from .models import ContactLink, ContactPost, Personnel, \
WorkCategory, Service, Skill, Work, Customer
Notice the added dot . in the from .models part. The import should be relative (assuming all of these models exist in the same main app).

Every Django project that I'm trying from git is showing the same error. Although I install all the requirements it is still showing error while I try to run the server.
This is the command which I try to execute:

it is because it provide its own virtual environment and in that environment not all the requirements install try to install all the requirements again to solve this problem from pycharm
the only thing you have to do is you have to specify your python interpreter and install your require software on that

Thank you for all the support I need to install some dependencies and re-install my python then after that I created a virtual environment and install dependencies.
I want to translate content of my models fields with django-modeltranslation.

I use django1.9 and the latest django-modeltranslation.
If you cant help me with error, please recommand any other model translation app.
I have came across some of them:
django-multilingual-ds9
django-dbgettext
django-transmeta
But they seem to be no longer supported. Do you know if any of these works , or do you know about any other working solution ?
If that matters i have to admit i use django-rosette
I found other app for model translation, django-hvad.
Works like a charm, have full django1.9 support, is easy to implement and is translator-friendly.
Are you sure you are using the latest django-modeltranslation? The issue was reported a while ago (https://github.com/deschler/django-modeltranslation/issues/349) and already fixed in version 0.11rc1 (https://pypi.python.org/pypi/django-modeltranslation/0.11rc1).
Okay, Im trying to use cryptoassets.django here. Iv got some help from Mikko about the python version being an issue(I was using 2.7.x, cryptoassets uses 3.4.x). I just solved by doing this
$virtualenv -p python3 venv
I also reinstalled Django because manage.py was pulling up error, probably because it was overwriting the bin/activate.. files.
With that out of the way. I installed the cryptoassets.django app
$pip3 install cryptoassets.django
Wonderfull. I set it up like the tutorial on bitbucket for the cryptoassets django intergration.
The problem comes in when i try to initialize the cryptoasset database with
$python manage.py cryptoassets_initialize_database
I get an Import error:

Cryptoassets is Python 3.4+ only and you are trying to run it on Python 2.
I am quite new to Django and Python. My environ is Win7 and Python3.4. Now following the tutorial in Django Official Website to build a web app. At first, everything works quite well and output are all expected and correct. But today when I re-run the command "python manage.py runserver", it gives me very strange err message as follows. Help please, many thanks!

RuntimeError: Settings already configured.
From docs:
If you set DJANGO_SETTINGS_MODULE, access settings values somehow, then call configure(), Django will raise a RuntimeError indicating that settings have already been configured.
Also, it’s an error to call configure() more than once, or to call configure() after any setting has been accessed.
The problem is, by the time you call settings.configure() in mysite.polls.admin, settings were already configured. One option for suppressing the error would be adding some sanity check:
if not settings.configured:
settings.configure()
