Question

Overnight hack, trying to create an environment where GAE code (using Python libs/packages) could be easily ported over to Heroku with minimal editing.

EDIT

Q: YAML offers static file sharing with only 3 lines of code, I’m trying to figure out how to implement this file sharing with _minimal_editing_ (keyword).

For example, to share the ‘static/’ folder. One solution is to implement a number of classes found in http://docs.webob.org/en/latest/file-example.html – not an elegant answer.

The big picture is to empower the developer with the freedom of choice to choose a (hopefully) better/cheaper cloud provider, follow steps 1,2,3… and the app will be up and running with minimal fuss. Hope this clears up the confusion.

---

In case anyone inquires, my code is as follows…

The “main.py” file:

import jinja2
import webapp2
import os

jinja_environment = jinja2.Environment(
    loader=jinja2.FileSystemLoader(
        os.path.join(os.path.dirname(__file__), 'templates')))


class HelloWebapp2(webapp2.RequestHandler):
    def get(self):
        template_values = { 'test': 'Hello World!!'}
        template = jinja_environment.get_template('jinja2_test.html')
        return self.response.out.write(template.render(template_values))


app2 = webapp2.WSGIApplication([
    ('/', HelloWebapp2)
], debug=True)

def main():
    from paste import httpserver
    port = int(os.environ.get("PORT", 5000))
    httpserver.serve(app2, host='0.0.0.0', port=port)

if __name__ == '__main__':
    main()

In the “requirements.txt” file:

Jinja2==2.6
webapp2==2.3
paste==1.7.5.1
webob==1.1.1

The output file “templates/jinja2_test.html“:

{{test}}

The default “procfile“:

web: python main.py

It sounds to me like the problem you’re trying to solve is serving static pages using Django on Heroku.

collectstatic seems to be the right answer for this:
web: python my_django_app/manage.py collectstatic –noinput; bin/gunicorn_django –workers=4 –bind=0.0.0.0:$PORT my_django_app/settings.py
