this all works locally though

I have scaled my web and worker to zero and started them back up still nothin. I have not seen any L,H,R error codes

EDIT

this part of my output

 2016-09-24T02:23:53.832216+00:00 app[worker.1]: 

its red, this color just started happening. Earlier in the day I had using django celery beat locally I get error 'PeriodicTask' object has no attribute '_default_manager' and I fixed it following a pul request

obj = self.model._default_manager.get(pk=self.model.pk)

turned to

98  Model = type(self.model)
99  obj = Model._default_manager.get(pk=self.model.pk)

EDIT

set my production DEBUG to True so I could see if I could see something. And it said

ImportError: No module named 'django.core.context_processors'

this was not in my heroku logs and as i mentioned before this works locally. I believe this is called failing silently. gonna see if I can figure this out. If someone has any idea what's going on and how to fix this, let me know. Right now google is my friend.

Answer 1

Maybe your local Django version is earlier then in requirements.txt, because in Django 1.8 built-in template context processors have been moved to django.template.context_processors .

Try this example settings:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.template.context_processors.media',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
