[gorf]

I config the example.
when I run python manage.py loaddata open_news/open_news.json
I got the errors below:

$ python manage.py loaddata open_news/open_news.json

What's wrong with it ?

Hi, I just commited the 0.2 version a couple of days ago, are you using this new version? Actually the example project was broken before in 0.1.x, that was one thing I fixed. I also updated the project layout to Django 1.4, so you need this new Django version to get the example up and running.

Thanks for your rapid reply.
My django is 1.4, The example in DDS version 0.1 can loaddata normally. And
I can run it after fix a little. But the newest 0.2 cause the error.

Hi, I think I found the problem, I was creating the example data with automatically generated objects by Django, which can be problematic (see: https://docs.djangoproject.com/en/dev/topics/serialization/#natural-keys). I just created a new fixture and committed it to GitHub: https://github.com/holgerd77/django-dynamic-scraper/blob/master/example_project/open_news/open_news.json just containing the essential app data. If you use that file for loaddata, I assume it should work. Would be nice, if you give some short feedback!

It's ok now.
