Heroku Bad Request (500)

Hi,

I'm going through the Deploying Django: Heroku workshop, and I'm doing excatly what Kenneth Love does, but I'm getting this Bad Request (500) when trying to visit my app - but the admin is working perfectly - any ideas how to fix this?

The entire project can be found at https://github.com/henrikac/KemiSpil

Oops, missed the repo. Going to import it and tinker, but just noticed your middleware classes were missing some I had.

https://devcenter.heroku.com/articles/django-assets

I had similar issues last night (static files) and following that resolved my issue. Let us know if you solve it before hand?

Nice coding btw - super easy to read

but just noticed your middleware classes were missing some I had - what middleware classes? :-)

I read that link earlier but I don't think it's because of staticfiles, because the admin-area looks perfect.

I will let you know if I solve it :-)

Solved the problem! :-D

It turned out to be my template settings that was causing the problem:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],  # Before: 'DIRS': ['templates']
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

But thank you Blaine McCarthy for taking the time to help me :-)
