Perfil Político

A platform for profiling candidates in Brazilian 2022 General Election, based entirely on open data.


This project requires Docker and Docker Compose.


To run the API, you must copy the .env.sample to a .env file. You can edit it accordingly if you want run in a production env.

Creating the container

You need to create the docker container:

$ docker-compose up -d

Note: You can use docker compose instead of docker-compose in this project.

Database initial setup

You should create your database by applying migrations:

$ docker-compose run --rm django ./ migrate


To run the project locally, you can simply use this command:

$ docker-compose up

The website and API will be available at localhost:8000 and the Jupyter at localhost:8888.

Bringing data into your database

Your local data/ directory is mapped, inside the container, to /mnt/data. Each command uses a CSV (compressed as .xz or not) from a public and available source. Use --help for more info. Yet some extra data can be generated with some Django custom commands.

Once you have download the datasets to data/, you can create your own database from scratch running:

$ docker-compose run --rm django ./ load_affiliations /mnt/data/filiacao.csv
$ docker-compose run --rm django ./ load_candidates /mnt/data/candidatura.csv
$ docker-compose run --rm django ./ link_affiliations_and_candidates
$ docker-compose run --rm django ./ link_politicians_and_election_results
$ docker-compose run --rm django ./ load_assets /mnt/data/bemdeclarado.csv
$ docker-compose run --rm django ./ pre_calculate_stats
$ docker-compose run --rm django ./ load_bills /mnt/data/senado.csv
$ docker-compose run --rm django ./ load_bills /mnt/data/camara.csv
$ docker-compose run --rm django ./ load_income_statements /mnt/data/receita.csv
# make sure to read the instructions on populate_company_info.sql before running the next command
$ docker-compose run --rm postgres psql -U perfilpolitico < populate_company_info.sql

⚠️ Note that it will change the primary keys for all candidates in the database! So be careful on running it for production environment because some endpoints as /api/candidate/<pk>/ depends on this primary key to retrieve the correct data.

Or you can update the data from your database using the commands:

$ docker-compose run --rm django ./ unlink_and_delete_politician_references
$ docker-compose run --rm django ./ load_affiliations /mnt/data/filiacao.csv clean-previous-data
$ docker-compose run --rm django ./ update_or_create_candidates /mnt/data/candidatura.csv
$ docker-compose run --rm django ./ link_affiliations_and_candidates
$ docker-compose run --rm django ./ link_politicians_and_election_results
$ docker-compose run --rm django ./ load_assets /mnt/data/bemdeclarado.csv clean-previous-data
$ docker-compose run --rm django ./ pre_calculate_stats
$ docker-compose run --rm django ./ load_bills /mnt/data/senado.csv clean-previous-data
$ docker-compose run --rm django ./ load_bills /mnt/data/camara.csv

Note: The code only updates data coming from the csv's to the database. It does not consider the possibility of changing data that is already in the database but does not appear in the csv for some reason (in this case the data in the database is kept untouched). Commands passing the clean-previous-data-option will replace all the data for the respective csv, thus changing all primary keys.
