Errors on Django Tests Tutorial 5, how to fix.

[Matt Schloepp]

I'm running Django on Windows with PostgreSQL database. I'm in tutorial 5 and have copy/pasted the code after it's initial failure. I've been following the tutorials to this point, with only a little side experimentation, and everything has been working. It looks like it DB related since I'm not using SQLite. I'm lost. What do I need to add or modify to get the tests to work?

Output:

Commenting out my Postgresql DB and putting back the default options for the sqlite DB fixed the issue. 

Is there a tests.py variable I could use to create an If..Else that would allow this to be automatic and not force me to edit my settings.py every time I wanted to run a test.

What version of Django are you running? I think an issue with starting up tests with PostgreSQL were fixed for 1.6 (but I haven't tried it myself). fwiw PostgreSQL is supported as well or better than any other choice, and SQLite just postpones the inevitable transition to something which is full-featured.

Django is 1.6 and Python is 2.7.5. On Windows 8.1, no virtual-env, but my actual project will be on a *nix VM. I accidentally download and install a development version, I think removed it before installing 1.6 but no previous django versions were installed on this system. Maybe dropping my db and starting over would fix the issue?

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.postgresql_psycopg2',

        'NAME': 'django',

'USER': 'matt',

'PASSWORD':'***********',

'HOST': '127.0.0.1',

        'PORT': '5432',

    },

    'OPTIONS': {

        'autocommit': True,

    }

I forgot to post DB settings
