Voter-Info

Find out who represents you now, and who else wants to.

dev setup guide.

Install:

# install pyenv, a tool for managing python versions, e.g. on mac with homebrew
# (more info here: https://github.com/pyenv/pyenv)
$ shell> brew install pyenv
$ shell> brew install pyenv-virtualenv

# Use pyenv to install the version of Python that you want (heroku runs on 3.6.4)
$ shell> pyenv install 3.6.4

# Create a virtualenv for voter_info
$ shell> pyenv virtualenv 3.6.4 voter_info

# Activate virtualenv
$ shell> pyenv activate voter_info

# (Optional) Set this as default env for this directory so whenever you're in this dir, you use this virtualenv
$ shell> pyenv local voter_info

# Confirm you are running the right python:
$ shell> which python
 .../.pyenv/shims/python

$ shell> python --version
Python 3.6.4

# Install requirements
$ shell> pip install -r requirements.txt

Database:

Ensure you have Postgres 10.3 installed locally. Heroku defaults to 10.3

https://www.postgresql.org/download/

# e.g. to install with homebrew on macos
$ shell> brew install postgresql

# If you installed postgres with homebrew, make sure you start your local postgres server:
$ bash> brew services start postgresql

On MacOS Ben Mathes has found homebrew helpful, but the Postgres.app is another option for running postgres with postGIS support.

install the GIS extensions for postgres:

We use the Geospatial Data Abstraction Library (GDAL). GDAL requires a few extra libraries you cannot install with pip.

https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/

With homebrew for mac: https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/#homebrew

With Postgres.app: https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/#postgresapp

E.g. with homebrew:

$ brew install postgis
$ brew install gdal
$ brew install libgeoip

Create a database

# Create a database provisioned to your user account
$ shell> createdb voter_info_dev

# create the voter_info_dev database user and grant it permissions on the voter_info_dev DB:
# connect to the voter_info_dev database in postgres:
$ shell> psql voter_info_dev

# create your dev user with a password (only for dev, not used in production).
# if you change the username or password from what is here, be sure to change the 'USER' and 'PASSWORD'
# values in the DATABASES value in $git_root/voter_info/voter_info/settings.py
$ psql> create role voter_info_dev_user with login encrypted password 'super_sekrit_dev_pw_1234';

# make sure your database user has access to the dev database:
$ psql> grant all on database voter_info_dev to voter_info_dev_user;

Check that django can connect to your dev database:

$ shell> python $git_root/voter_info/manage.py dbshell

Run all migrations to create your database schema:

####################IMPORTANT#################
# THE FIRST TIME YOU MIGRATE, YOU MUST HAVE SUPERUSER PRIVLIGES
# TO CREATE YOUR postGIS (geography stuff) EXTENSION:
$ postgres> alter role voter_info_dev_user SUPERUSER;
$ shell> python $git_root/voter_info/manage.py migrate
$ postgres> alter role voter_info_dev_user NOSUPERUSER;

Import Shapefiles to the Postgres Database

# run the custom manage.py command:
& shell> python $git_root/voter_info/manage.py import_shapefiles

Frontend:

# We'll use yarn for package management. The yarn installer will also install node if
# it doesn't find it.
$ brew install yarn

# You will probably want a node version manager if you don't already have one.
# @ericsandine recommends `n`
$ npm install -g n

# Then install the production version of Node
# This command will install it and switch to the version
# You can swap versions by using `n` if needed
$ n 10.9.0

# Now install the current dependencies
$ yarn install

# To install a new package use
$ yarn add <some-some-awesome-package>

Run your local dev server

# don't forget to have the heroku CLI installed
$ shell> npm install -g heroku

# To run your dev server use heroku, which is compatible with procfiles
# (recall that a procfile is basically a list of commands to run)
$ heroku local -f $git_root/Procfile.local

Django will run on http://127.0.0.1:8000/ The react dev server will run on http://127.0.0.1:5000/ (or the next open port) and proxy requests to Django

Pull Requests and Heroku Builds.

Every time you create a PR, heroku will kick off a build to see if it can create a server running the version of your PR. You can see the builds here:

Deployment Guide

install the heroku command line: https://devcenter.heroku.com/articles/heroku-command-line

# don't forget to have the heroku CLI installed
$ shell> npm install -g heroku

Then follow the guide to get started: https://devcenter.heroku.com/articles/heroku-cli#getting-started

$ shell> heroku login

# confirm your login is part of the TEC:
$ shell> heroku teams
techequity
$ shell> heroku apps --team techequity
=== Apps in team techequity
voter-info
voter-info-pr-15
...

The Heroku CLI defaults to your personal account and requires the --team flag when performing team actions. If you generally work under an organization, you can set the HEROKU_ORGANIZATION environment variable in order to default to that organization.

$ bash> export HEROKU_ORGANIZATION=techequity
$ bash> heroku apps
=== Apps in team techequity
voter-info
voter-info-pr-15
...
