Mezzanine on Heroku

Question

I'm trying to get a Mezzanine (Django) app up on Heroku. I have a custom theme in an app in the project.

I'm getting this error from the herokuapp site:

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

I'm getting this error from "heroku logs":

Here's my installed apps var in settings.py (cc is my theme/app name):

INSTALLED_APPS = (
    "cc",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.redirects",
    "django.contrib.sessions",
    "django.contrib.sites",
    "django.contrib.sitemaps",
    "django.contrib.staticfiles",
    "mezzanine.boot",
    "mezzanine.conf",
    "mezzanine.core",
    "mezzanine.generic",
    "mezzanine.blog",
    "mezzanine.forms",
    "mezzanine.pages",
    "mezzanine.galleries",
    "mezzanine.twitter",
    #"mezzanine.accounts",
    #"mezzanine.mobile",
    "gunicorn",
)

My requirements.txt has gunicorn in it. Also, both run_gunicorn and collectstatic work locally from within my venv. Why is this happening? I followed this: https://gist.github.com/joshfinnie/4046138 for my urls.py (note that my requirements.txt is generated from pip freeze > requirements.txt so it's up-to-date).

Here's my Procfile:

web: python manage.py collectstatic --noinput; python manage.py run_gunicorn -b 0.0.0.0:$PORT

Answer 1

Is your Procfile in the same path as settings.py/manage.py or outside? I had a similar issue and move my Profile up one level in your project directory. This is how foreman executes on a normal Django project. However, I'm running it with wsgi.

Here's my Procfile

Procfile: web: python manage.py collectstatic --noinput; gunicorn your_project.wsgi -b 0.0.0.0:$PORT

Answer 2

It looks like you don't have all of the required apps installed hence the lack of collectstatic and run_gunicorn. Ensure that your requirements.txt has all necessary packages as required by Heroku.

My requirements.txt on a current Mezzanine project contains:

Cartridge==0.9.2
Django==1.6.2
Mezzanine==3.0.9
Pillow==2.3.1
bleach==1.4
boto==2.27.0

dj-static==0.0.5
django-s3-storages-utils==0.1.0
django-storages==1.1.8
django-toolbelt==0.0.1
filebrowser-safe==0.3.2
future==0.9.0
grappelli-safe==0.3.7
gunicorn==18.0
html5lib==0.999
oauthlib==0.6.1
pisa==3.0.33
psycopg2==2.5.2
pystache==0.5.3
pytz==2014.2
requests==2.2.1
requests-oauthlib==0.4.0
