Python dependencies

Pipenv

This projects uses Pipenv.

Pipenv is a tool that aims to bring the best of all packaging worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world.

Some of its great features are:

Enables truly deterministic builds, while easily specifying only what you want.
Generates and checks file hashes for locked dependencies.
Automatically install required Pythons, if pyenv is available.
Automatically finds your project home, recursively, by looking for a Pipfile.
Automatically generates a Pipfile, if one doesn’t exist.
Automatically creates a virtualenv in a standard location.
Automatically adds/removes packages to a Pipfile when they are un/installed.
Automatically loads .env files, if they exist.

Proceed

After you have cloned the repo, make:

$ pipenv install --python 3.6

This will install a virtual environment for the project, with Python 3.6, Django and all the rest Python dependencies.

Node.js dependencies

It's essential to use npm >= 6.0.0 and node >= 10.0.0 in order to update properly the package-lock.json.

There are some libraries (css, js) used on either the frontend or the development phase. To install them, make:

$ npm install

This will create a bunch of folders and files under node_modules.

Other dependencies

One of the Python dependencies is wkhtmltopdf. Besides the proper Python package, you have to install the system package. In our experience with Ubuntu 18.04 Bionic you should do the following:

$ wget https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
$ sudo dpkg -i https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
## in case there are other not resolved dependencies
$ sudo apt-get -f install

Developing

EditorConfig

Please install the corresponding extension of EditorConfig in your favourite editor. Thus your editor will pick the settings stored in .editorconfig.

This configuration avoids conflicts with a lot of settings, mainly with tabs widths.

Customize your settings

Feel free to change some of the settings creating a file called .venv on the root of the project.

Database

We are using PostgreSQL as database management system. In order to configure the project correctly it is important to follow some indications:

Approach A

Install PostgreSQL.
Create a database and a user/password with full access to that database.
Set the following keys in the .env file: DATABASE_NAME, DATABASE_USER and DATABASE_PASSWORD.

Approach B

Install Docker.
Use the following Dockerfile:

postgres:
  image: "postgres:10.4"
  environment:
    POSTGRES_DB: "my_db"
  ports:
    - 5432:5432

Afterwards, in both cases, you can apply migrations with:

$ pipenv run python manage.py migrate

Launching services

In order to develop, you have to launch the following services:

$ pipenv run python manage.py runserver # on one terminal
$ gulp watch                 # on another terminal

After that, you'll be able to access the project on http://127.0.0.1:8000

The changes made both in Python files or static files will be detected by the services and will reload them.

Model graphs

$ pipenv run python manage.py graph_models events organizations locations speakers tickets schedule -g -S -o models.png
