As part of an automation process I need to create the superuser for Django via python in the CLI.
I could consider other possibilities to this problem but only if they're easily scritable with ansible.
Anyway, this is what I have so far (for Django 1.6)
However, when I run this i get this error.
Any idea what's wrong or how to fix it please? It seems strange it should complain about DJANGO_SETTINGS_MODULE when it has been explicitly set..
The problem you're seeing is because you're running it as two separate python commands. You import the settings in the first, then python exits, then you start the second (which hasn't imported settings).
If you put them all into one python -c call, it should work.
It also looks like you're not passing the right number of arguments to .db_manager(). See this for more details:

Using .update with nested Serializer to post Image
django,rest,django-models,django-rest-framework,imagefield
As noted in the docs, .update() doesn't call the model .save() or fire the post_save/pre_save signals for each matched model. It almost directly translates into a SQL UPDATE statement. https://docs.djangoproject.com/en/1.8/ref/models/querysets/#update Finally, realize that update() does an update at the SQL level and, thus, does not call any save() methods on...

Does Django implement user permissions in databases with models?

Note that it's not a shortcoming be really the...
