Re: Not getting static files with django & heroku deployment

Hi Martin,

First let me say unapologetically that I love PyDanny and his work and contributions to the Django community, especially Two Scoops. However, you should know that the philosophy he espouses there is very different from the one Heroku espouses. I've been told he talks about that somewhere, but I've never seen it personally.

I won't go into too much detail, but you can read about it here: https://devcenter.heroku.com/articles/architecting-apps

What you need more than anything is the Heroku Django template :  https://devcenter.heroku.com/articles/django-app-configuration

Try that first. Follow the directions carefully, then let us know if you still need help.

Hello,

I'm developing a webapp with Django 1.7 (project_name is "sonata") and the project layout from the "Two scoops of Django 1.6", so I have a 3-tier basic folder tree.

.  ├── requirements  └── sonata      ├── person      │   └── templatetags      ├── registration      ├── sonata      │   └── settings      ├── static      │   ├── css      │   │   └── images      │   ├── fonts      │   └── js      ├── templates      │   ├── personApp      │   └── registrationApp      └── utils          └── templatetags

I have a problem when deploying on Heroku. I have achieved the deployment, but the static files are not being served to the browser.

I know I should force some way of serving the static files through the settings and have googled about. I've seen many ways and read about using Amazon services, but I'm looking for the easiest one, which will make the future production deployment easy as well with gUnicorn (I hope).

I tried modifying the settings file (which is the heroku.py one, which overrides the base.py) and changing values for STATIC_ROOT, STATICFILES_DIRS and adding the line:

    urlpatterns += static(settings.MEDIA_URL, document_root=settings.STATIC_ROOT)

    

I've tried as well running:

    heroku run sonata/manage.py collectstatic

    

before doing 

    git push heroku master

but nothing happens, even checking with 

    heroku run ls sonata/assets 

that the files are being copied.

Please, I would like some orientation for really understanding what I'm doing wrong and mending it. 

When finding out about heroku and deployment I met also some sample ProcFiles which used a project_name.wsgi file and I don't know anything about it.

I could use use some help, because the more webs I read, the more confused I get. Please assume I know very little about deployments. A link would be useful, but it has to show newbie's material :-(

Thank you very much on advance.
