Seismic Risc


:romania: Un cutremur în București nu este o situație ipotetică.
Este o certitudine că acest lucru se va întâmpla.
În acest context, la mai bine de 40 de ani de la cutremurul din 1977, memoria colectivă a ascuns în profunzime amintirile acelui dezastru în încercarea de a-și înăbuși teama.
Dar realitatea este că, patru decenii mai târziu, Bucureștiul, la fel ca restul orașelor cu risc seismic ridicat, nu ar face față unui asemenea eveniment, iar pierderile de vieți omenești ar fi uriașe.
Exercițiul Seism 2018 derulat de DSU arată că cel puţin 4.587 persoane şi-ar pierde viaţa, iar 8.585 ar fost rănite, 6 spitale vor fi distruse, 23 de unităţi spitaliceşti distruse parţial, iar 9 avariate, dar funcţionale.
O estimare, am spune noi, destul de optimistă.

Ce putem face pentru a deveni mai puțin vulnerabili?
Să știm totul despre oraș, despre clădirile în care locuim astfel încât să putem cere consolidarea lor.
Seismic Risc nu este doar "un nou site de informare", ci o platformă care colectează și validează apoi cu experți date despre clădirile din România, la nivel național, ajută asociațiile de proprietari să își consolideze clădirile, te ține la curent cu legislația și ți-o explică și are grijă să ai la îndemână informații utile la orice moment.

:gb: An earthquake in Bucharest is not a hypothetical situation.
It is certain that this will happen.
In this context, after more than 40 years from the 1977 earthquake, the collective memory has hidden deep the memories of that disaster in its attempt of stifling its fear.
The reality is that, four decades later, Bucharest, as well as the rest of the cities with a high seismic risk, would not stand up tu such an event, and the loss of life would be tremendous.
The Earthquake 2018 Exercise conducted by the DSU shows that at least 4,587 people would have died and 8,585 would have been injured, 6 hospitals would be destroyed, 23 more would be partially destroyed, and 9 would be damaged, though still functional.
An estimation that we would consider quite optimistic.

What can we do to become less vulnerable?
Find out everything about the city, about the buildings in which we live so that we can ask for their consolidation.
Seismic Risc is not just "a new information site", but a platform that collects and then validates with the help of experts data about the buildings in Romania, at a national level, it helps owners associations to consolidate their buildings, it keeps you in touch with the current legislation and explains it to you, and it makes sure that you have useful information at your disposal at all times.

Let's save lives together.

Getting started

Risc Seismic API is a Django application, built on top of Python 3.7+ with a PostgreSQL database, while the Client is a React single page application.

Pre-requisites

In order to run the project locally, you need to have Docker and docker-compose installed.

You can install the above mentioned packages manually, or you can use our helper commands.

On Ubuntu 18.04+ run:

make install-docker-ubuntu

On MacOS run:

make install-docker-osx

On other platforms please follow the instructions described here:

The Docker versions the Makefile was tested with are:

$ docker --version
Docker version 19.03.5, build 633a0ea
$ docker-compose --version
docker-compose version 1.24.1, build 4667896b

Initial set-up

Initialise the database and development fixtures:

make init-env

External services API keys

In order to have a fully functional project, you have to get two API keys: HERE Maps API Key and hCAPTCHA API Key.

HERE Maps API Key

Tutorial: https://developer.here.com/tutorials/getting-here-credentials/

Keys added to the .env file:

# the same key can be used for both variables
HERE_MAPS_API_KEY
REACT_APP_HERE_MAPS_API_KEY

hCAPTCHA API Key

  1. Create a hCAPTCHA account
  2. Go to your settings page
  3. Add a new key and add it to the environment variables list

Keys added to the .env file:

REACT_APP_CAPTCHA_API_KEY

Starting the project

First check the .env file created by the init command and see if there are any environment variables that you might need to provide or change. This file is used by docker-compose to pass the environment variables to the container it creates.

Get the project up and running:

docker-compose up

You should be able to access the local environment site and admin at the following URLs:

If you have problems starting the project, first check out the FAQ and if that doesn't work, ask someone from the project's channel.
Maybe the issue you just had is worth adding to the FAQ, wouldn't it?

To work on running containers that were started using docker-compose up, open another terminal and:

cd path/to/repo
docker-compose exec api bash
# or
docker-compose exec client bash

In order to see all available commands run:

make

Starting the project without docker

Windows platform

Prerequisites
  1. PostgreSQL
  2. Python 3.7
  3. Node.js
Steps to set your environment
  1. In project directory run:
python -m venv .venv
.venv\Scripts\activate.bat
pip install -r ./api/requirements-dev.txt
copy .env.dist .env

Check the .env file created by the copy command and see if there are any environment variables that you might need to provide or change. Double check database config line in .env. It has to follow this pattern: postgres://USER:[email protected]:PORT/NAME

Run following in order to set needed environment variables:

activate_dev_env.bat
  1. Check database connection. If this fails double check database configuration.
python api/wait_for_db.py
  1. Run migrations:
python api/manage.py migrate --noinput
  1. Create admin user (user to login into admin pannel):
python api/manage.py createsuperuser
  1. Load dummy data in database:
python api/manage.py loaddata buildings
python api/manage.py loaddata pages
  1. Install node modules.
cd client
npm install

Steps needed to start development servers

1. Start API server.

Open terminal in project direcotry and run environment activation script, then
start the server.

.venv\Scripts\activate.bat
activate_dev_env.bat
python api\manage.py runserver 0.0.0.0:8000

Check functionality at http://localhost:8000 you shoul get 404 page.

2. Start front-end server.

Open terminal in project direcotry and run environment activation script, then
start the server.

activate_dev_env.bat
cd client
npm start

Check functionality at http://localhost:3000.

Development

When creating new models in Django, in order to make sure they are generated in a clean environment, it is recommended to generate the migration files using the make command:

make makemigrations && make migrate

When you need to add/remove requirements or restrict the version of a requirement, edit the requirements.in (prod) and the requirements-dev.in (dev) files accordingly. After doing this run:

make update-requirements

This will create a clean environment where it uses the pip-tools library to compile the corresponding requirements.txt files with the versions of the packages pinned. This is important as it guarantees that every environment this service runs in, has the same dependencies installed and minimizes the risk of works on my machine.

Known Issues

Client hot-reload on Windows Docker is not working

Try following these steps:

open up a terminal in seismic-risc_client container

cd ./node_modules/react-scripts/config/

vi webpackDevServer.config.js

on the exported config object, update the value of watchOptions to include the following properties:

aggregateTimeout: 100,
poll: 500

save the file and restart the client container

This way, webpack-dev-server should be watching files in polling mode, instead of listening for file change events.

In VS Code, ESLint fails to load the Prettier plugin

Add the following option to user settings in VS Code if ESLint fails to load the Prettier plugin.

{
  "eslint.workingDirectories": [
    {
      "mode": "auto"
    }
  ]
}

Management Commands

The new custom command can be called using
python manage.py buildings <number>
required arguments:

  • --delete
  • --create
cd path/to/repo
docker-compose exec api bash
[email protected]:/code# python manage.py buildings 30 --create
100% |███████████████████████████████████████████████████████████████████████████████████████████████████████████████| 30/30 [00:00<00:00, 37.89it/s]
Successfully created 30 buildings.
[email protected]:/code# python manage.py buildings 25 --delete
Successfully deleted 25 buildings.

Testing

Local development testing:

cd path/to/repo
docker-compose exec api bash
[email protected]:/code# pytest

Pipeline testing:

make test

Production

In order to get the container ready for production use we need to first build it:

docker build -t seismic-risc:latest ./api

Use the prod.env.dist template file and create a prod.env file with the correct environment variables and run like so:

docker run --env-file prod.env -p HOST_PORT:GUNICORN_PORT seismic-risc:latest

Or, you can provide all the environment variables at runtime:

docker run -e DJANGO_CONFIGURATION=Prod -e DJANGO_SECRET_KEY= -e DATABASE_URL=postgres://USER:[email protected]:PORT/NAME -e GUNICORN_PORT=5000 -e GUNICORN_WORKERS=2 -p HOST_PORT:GUNICORN_PORT seismic-risc:latest

After testing the container runs properly, tag and upload the image to Docker hub:

docker tag seismic-risc:latest code4romania/seismic-risc:latest
docker push code4romania/seismic-risc:latest
