example data fails to load

After getting to the point where manage.py will run at all, it fails to loaddata:

$ ./manage.py loaddata example_database.json
Problem installing fixture 'example_database.json': Traceback (most recent call last):

I think you should use develop branch and use example_14 for django 1.4.x and don't run "python manage.py reset" contenttypes.

Or you've to use django1.3.x for example version

I've tested on various operating systems, and various configurations, but I am not able to replicate any of the issues you're having, sorry.

In fact in every case following the steps at https://github.com/evildmp/Arkestra/blob/develop/docs/getting_started/installation.rst seems to work as it should. The exception has been when some sort of PyPI service issue arose; in that case simply running the pip install command again fixed it.

I'd like to know if what happens if you follow these steps exactly:

• virtualenv arkestra
• cd arkestra/
• source bin/activate
• pip install -e git+https://github.com/evildmp/Arkestra.git@develop#egg=Arkestra # install Arkestra & dependencies
• pip install -r src/arkestra/REQUIREMENTS.txt # install the things that pip can't do automatically
• cd src/arkestra/example_14
• python manage.py syncdb --noinput # set up a new database; don't prompt for superuser
• python manage.py loaddata example_database.json # load the example database from the fixture
• python manage.py runserver 0.0.0.0:8000 # go!

You should be able simply to paste them into your terminal in one go. No prompts are involved.

Ran through the steps and today it works. Thank you for your help.

Great. Do drop onto #arkestra on irc.freenode.net while you're getting it going. It's also really helpful to me to see where the gaps are in the documentation are, or other problems.
