EveryElection requires Python 3.x and Postgres.
pip install -U pip
pip install -r requirements.txt
pip install -r requirements/local.txt
Gotcha: If you're having trouble installing psycopg2-binary on Apple silicon, set your library path before retrying the install:
export LIBRARY_PATH=$LIBRARY_PATH:/opt/homebrew/opt/openssl/lib
npm ci
By default, EveryElection uses PostgreSQL with the PostGIS extension. To set this up locally, first install the packages:
sudo apt-get install postgresql postgis
# MacOS
brew install postgresql postgis
Create the database:
sudo -u postgres createdb every_election
# MacOS
createdb every_election
Finally, add the postgis extension to the database:
sudo -u postgres psql -d every_election -c "CREATE EXTENSION postgis;"
# MacOS
psql -d every_election -c "CREATE EXTENSION postgis;"
Create your local.py settings file:
cp every_election/settings/local.example.py every_election/settings/local.py
In this file, add your database credentials to the DATABASES dict.
To populate the database from a dumpfile, run:
pg_restore -d every_election -C backup.dump
If you have a DC AWS account, you can grab the latest production db backup like so:
export AWS_PROFILE=dev-ee-dc # you may need to configure this profile
# Drop and re-create the local DB
dropdb every_election
createdb every_election
# Pipe the latest backup into the local DB
LATEST_FILE=`aws s3 ls s3://dc-ee-production-database-backups/every_election/ | sort | tail -n 1 | rev | cut -d' ' -f 1 | rev`
aws s3 cp s3://dc-ee-production-database-backups/every_election/$LATEST_FILE - | pg_restore -d every_election --if-exists --clean
We strongly advise you to create a local backup before dropping your database!
