=========================
Hey ! Tu veux devenir un mec bien et en plus devenir bon en python si tu l'es pas déjà ?
Il se trouve que le sith AE prévu pour l'été 2016 a besoin de toi !
Pour faire le sith, on utilise le framework Web [Django](https://docs.djangoproject.com/fr/1.11/intro/)
N'hésite pas à lire les tutos et à nous demander (ae.info@utbm.fr).
Bon, passons aux choses sérieuses, pour bidouiller le sith sans le casser :
Ben en fait, tu peux pas le casser, tu vas juste t'amuser comme un petit fou sur un clone du sith.
C'est pas compliqué, il suffit d'avoir [Git](http://www.git-scm.com/book/fr/v2), python et pip (pour faciliter la gestion des paquets python).
Tout d'abord, tu vas avoir besoin d'un compte Gitlab pour pouvoir te connecter.
Ensuite, tu fais :
`git clone https://ae-dev.utbm.fr/ae/Sith.git`
Avec cette commande, tu clones le sith AE dans le dossier courant.
```bash
cd Sith
virtualenv --system-site-packages --python=python3 env
source env/bin/activate
pip install -r requirements.txt
./manage runserver
```
Attention aux dépendances système, à voir dans le README.md
Maintenant, faut passer le sith en mode debug dans le fichier de settings personnalisé.
```bash
echo "DEBUG=True" > sith/settings_custom.py
echo 'SITH_URL = "localhost:8000"' >> sith/settings_custom.py
```
Enfin, il s'agit de créer la base de donnée de test lors de la première utilisation
```bash
./manage.py setup
```
Et pour lancer le sith, tu fais `python3 manage.py runserver`
Voilà, c'est le sith AE. Il y a des issues dans le gitlab qui sont à régler. Si tu as un domaine qui t'intéresse, une appli que tu voudrais développer, n'hésites pas et contacte-nous.
Va, et que l'AE soit avec toi.
# Black
Pour uniformiser le formattage du code nous utilisons [Black](https://github.com/ambv/black). Cela permet d'avoir le même codestyle et donc le codereview prend moins de temps. Tout étant dans le même format, il est plus facile pour chacun de comprendre le code de chacun ! Cela permet aussi d'éviter des erreurs (y parait 🤷‍♀️).
Installation de black:
```bash
pip install black
```
## Sous VsCode:
Attention, pour VsCode, Black doit être installé dans votre virtualenv !
Ajouter ces deux lignes dans les settings de VsCode
```json
{
"python.formatting.provider": "black",
"editor.formatOnSave": true
}
```
## Sous Sublime Text
Il faut installer le plugin [sublack](https://packagecontrol.io/packages/sublack) depuis Package Control.
Il suffit ensuite d'ajouter dans les settings du projet (ou en global)
```json
{
"sublack.black_on_save": true
}
```
Si vous utilisez le plugin [anaconda](http://damnwidget.github.io/anaconda/), pensez à modifier les paramètres du linter pep8 pour éviter de recevoir des warnings dans le formatage de black
```json
{
"pep8_ignore": [
"E203",
"E266",
"E501",
"W503"
]
}
```
Sites et doc cools
------------------
[Classy Class-Based Views](http://ccbv.co.uk/projects/Django/1.11/)
Helpers:
`./manage.py makemessages --ignore "env/*" -e py,jinja`
`for f in $(find . -name "*.py" ! -path "*migration*" ! -path "./env/*" ! -path "./doc/*"); do cat ./doc/header "$f" > /tmp/temp && mv /tmp/temp "$f"; done`
Pour contribuer au projet, vous pouvez vous référer à la documentation disponible à https://sith-ae.readthedocs.io/.
Et n'oubliez pas, contribuer c'est la vie !

## Sith AE
### Dependencies:
See requirements.txt
You may need to install some dev libraries like `libmysqlclient-dev`, `libssl-dev`, `libjpeg-dev`, `python3-xapian`, or `zlib1g-dev` to install all the
requiered dependancies with pip. You may also need `mysql-client`. Don't also forget `python3-dev` if you don't have it
already.
You can check all of them with:
```bash
sudo apt install libmysqlclient-dev libssl-dev libjpeg-dev zlib1g-dev python3-dev libffi-dev python3-dev libgraphviz-dev pkg-config python3-xapian gettext
```
On macos, you will need homebrew
```bash
brew install xapian
```
If it doesn't work it's because it need [this pull request](https://github.com/Homebrew/homebrew-core/pull/34835) to be validated.
The development is done with sqlite, but it is advised to set a more robust DBMS for production (Postgresql for example)
### Get started
To start working on the project, just run the following commands:
```bash
git clone https://ae-dev.utbm.fr/ae/Sith.git
cd Sith
virtualenv --system-site-packages --python=python3 env
source env/bin/activate
pip install -r requirements.txt
./manage.py setup
```
To start the simple development server, just run `python3 manage.py runserver`
For more informations, check out the CONTRIBUTING.md file.
### Logging errors with sentry
To connect the app to sentry.io, you must set the variable SENTRY_DSN in your settings custom. It's composed of the full link given on your sentry project
### Generating documentation
There is a Doxyfile at the root of the project, meaning that if you have Doxygen, you can run `doxygen Doxyfile` to
generate a complete HTML documentation that will be available in the *./doc/html/* folder.
### Collecting statics for production:
We use scss in the project. In development environment (DEBUG=True), scss is compiled every time the file is needed. For production, it assumes you have already compiled every files and to do so, you need to use the following commands :
```bash
./manage.py collectstatic # To collect statics
./manage.py compilestatic # To compile scss in those statics
```
### Misc about development
#### Controlling the rights
When you need to protect an object, there are three levels:
* Editing the object properties
* Editing the object various values
* Viewing the object
Now you have many solutions in your model:
* You can define a `is_owned_by(self, user)`, a `can_be_edited_by(self, user)`, and/or a `can_be_viewed_by(self, user)`
method, each returning True is the user passed can edit/view the object, False otherwise.
This allows you to make complex request when the group solution is not powerful enough.
It's useful too when you want to define class-wide permissions, e.g. the club members, that are viewable only for
Subscribers.
* You can add an `owner_group` field, as a ForeignKey to Group. Second is an `edit_groups` field, as a ManyToMany to
Group, and third is a `view_groups`, same as for edit.
Finally, when building a class based view, which is highly advised, you just have to inherit it from CanEditPropMixin,
CanEditMixin, or CanViewMixin, which are located in core.views. Your view will then be protected using either the
appropriate group fields, or the right method to check user permissions.
#### Counting the number of line of code
```bash
sudo apt install cloc
cloc --exclude-dir=doc,env .
```
#### Updating doc/SYNTAX.md
If you make an update in the Markdown syntax parser, it's good to document
update the syntax reference page in `doc/SYNTAX.md`. But updating this file will
break the tests if you don't update the corresponding `doc/SYNTAX.html` file at
the same time.
To do that, simply run `./manage.py markdown > doc/SYNTAX.html`,
and the tests should pass again.

This is the source code of the UTBM's student association available at https://ae.utbm.fr/.
All documentation is in the ``docs`` directory and online at https://sith-ae.readthedocs.io/. This documentation is written in French because it targets a French audience and it's too much work to maintain two versions. The code and code comments are strictly written in English.
If you want to contribute, here's how we recommend to read the docs:
* First, it's advised to read the about part of the project to understand the goals and the mindset of the current and previous maintainers and know what to expect to learn.
* If in the first part you find you need more background about what we use, we provide some links to tutorials and documentation at the end of our documentation. Feel free to use it and complete it with what you found helpful.
* Keep in mind that this documentation is thought to be read in order.
To join our team :
* Send a mail at mailto:ae.utbm.fr

Introduction
============
Le but de ce projet est de fournir à l'Association des Étudiants de l'UTBM une plate-forme pratique et centralisée de ses services. Le Sith de l'AE tient à jour le registre des cotisations à l'association, prend en charge la trésorerie, les ventes de produits et services, la diffusion d’événements, la gestion de la laverie et bien plus encore. Il est conçu de manière suffisamment générique pour être facilement adaptable à une autre association.
C'est un projet bénévole qui tire ses origines des années 2000. Il s'agit de la troisième version du site de l'association initiée en 2015. C'est une réécriture complète en rupture totale des deux versions qui l'ont précédée.
Pourquoi réécrire le site
-------------------------
L'ancienne version du site, sobrement baptisée `ae2 <https://ae-dev.utbm.fr/ae/ae2>`_ présentait un nombre impressionnant de fonctionnalités. Il avait été écrit en PHP et se basait sur son propre framework maison.
Malheureusement, son entretiens était plus ou moins hasardeux et son framework reposait sur des principes assez différents de ce qui se fait aujourd'hui, rendant la maintenance difficile. De plus, la version de PHP qu'il utilisait était plus que déprécié et à l'heure de l'arrivée de PHP 7 et de sa non rétrocompatibilité il était vital de faire quelque chose. Il a donc été décidé de le réécrire.
La philosophie du projet
------------------------
Pour éviter les erreurs du passé, ce projet met l'accent sur la maintenabilité. Le choix des technologies ne s'est donc pas fait uniquement sur le fait qu'elle soit récentes, mais également sur leur robustesse, leur fiabilité et leur potentiel à être maintenu loin dans le futur.
La maintenabilité passe également par le choix minutieux des dépendances qui doivent eux aussi passer l'épreuve du temps pour éviter qu'elles ne mettent le projet en danger.
Cela passe également par la minimisation des frameworks employés de manière à réduire un maximum les connaissances nécessaires pour contribuer au projet et donc simplifier la prise en main. La simplicité est à privilégier si elle est possible.
Le projet doit être simple à installer et à déployer.
Le projet étant à destination d'étudiants, il est préférable de minimiser les ressources utilisées par l'utilisateur final. Il faut qu'il soit au maximum économe en bande passante et calcul côté client.
Le projet est un logiciel libre et est sous licence GPL. Aucune dépendance propriétaire ne sera acceptée.
This diff is collapsed.
Le versioning
=============
Dans le monde du développement, nous faisons face à un problème relativement étrange pour un domaine aussi avancé : on est brouillon.
On teste, on envoie, ça marche pas, on reteste, c'est ok. Par contre, on a oublie plein d'exceptions. Et on refactor. Ça marche mieux mais c'est moins rapide, etc, etc.
Et derrière tout ça, on fait des trucs qui marchent puis on se retrouve dans la mouise parce qu'on a effacé un morceau de code qui nous aurait servi plus tard.
