Density-X Heroku deployment

This app was created on top of python-getting-started. The readme for the original infrastructure is below.

Test on your local.

Create a virtual environment to test the app on your local machine.

$ conda env export -n venv
$ source activate venv
$ pip install -r requirements.txt

Then run the thing...

$ python manage.py collectstatic

(answer yes)

$ heroku local web

Now access the local deployment at http://localhost:5000

If you are having issues getting this to run, your 5000 port may be busy. Kill all processes on that port with:

$ kill `lsof -i :5000`

##Push changes and deploy on Heroku.

$ git add .
$ git commit -m "commit message"
$ git push heroku master
$ heroku open

Done forget to also push to github (here; origin master) where you should definitely also be saving these files:

$ git add .
$ git commit -m "commit message"
$ git push origin master

##The file structure The file /uploads/core/view.py is where your python code (the actual code being deployed, in this case DensityX.py) lives.

The file /uploads/templates/base.html is the base html file that is essentially your index.html file. All other html files extend base.

The file /uploads/core/templates/core/home.html is where the stuff on your index page is defined. For example, the upload button in DensityX is defined here.

##Some files you'll need Use python-getting-started from heroku for an example of a working setup with all required files (readme for original is below)

requirements.txt file - all dependencies and versions go here. To get version: run python, import module, type:

$ print module.__version__

urls.py - list of all the "pages" on the web interface

view.py - where the actual python code gets called and executed. The script to run must be wrapped as a function like:

def my_python_script(some_thing)

python-getting-started

A barebones Python app, which can easily be deployed to Heroku.

This application supports the Getting Started with Python on Heroku article - check it out.

Running Locally

Make sure you have Python installed properly. Also, install the Heroku Toolbelt and Postgres.

$ git clone [email protected]:heroku/python-getting-started.git
$ cd python-getting-started

$ pip install -r requirements.txt

$ createdb python_getting_started

$ python manage.py migrate
$ python manage.py collectstatic

$ heroku local

Your app should now be running on localhost:5000.

Deploying to Heroku

$ heroku create
$ git push heroku master

$ heroku run python manage.py migrate
$ heroku open
