h2. %{margin-left:0px; font-weight:bold; font-size:25px;  display:block; color:red;}II - Get the project (from gitlab)%

h3. Gitlab management interface

https://gitlab.irap.omp.eu/epallier/pyros

https://gitlab.irap.omp.eu/epallier/pyros/team

Browse the code: https://gitlab.irap.omp.eu/epallier/pyros/tree/master

h3. Project structure

Once you have fetched the project, you should obtain this structure:

<pre>

PYROS/

├── install/

│   └── REQUIREMENTS.txt

│   └── INSTALLATION.txt

├── public/

│   └── static/

├── src/

│   ├── manage.py

│   ├── pyros/

│   │   ├── __init__.py

│   │   ├── __pycache__

│   │   ├── settings.py

│   │   ├── urls.py

│   │   └── wsgi.py

│   └── pyrosapp/

│       ├── __init__.py

│       ├── admin.py

│       ├── apps.py

│       ├── migrations

│       ├── models.py

│       ├── tests.py

│       └── views.py

</pre>

h3. From the terminal

<pre>

git clone https://gitlab.irap.omp.eu/epallier/pyros.git PYROS

(or also : git clone git@gitlab.irap.omp.eu:epallier/pyros.git PYROS)

</pre>

This creates a PYROS/ folder containing the project (with a .git/ subfolder for synchronization with the git repository)

_If you just wanted a static copy of the project (without synchronization), just remove the .git/ folder:_

<pre>

$ rm -r .git/

</pre>

h3. From Eclipse

1) Deactivate CA certificate verification

Window -> Preferences -> Team -> git -> configuration -> Add entry

Key = http.sslVerify

Value = false

2) Fetch the project

File/Import project from git

Select repository source: Clone URI: https://gitlab.irap.omp.eu/epallier/pyros.git

Directory: 

par défaut, il propose : /Users/epallier/git/pyros

mais on peut le mettre ailleurs (c'est ce que j'ai fait)

initial branch: master

remote name: origin

Import as general project

Project name: PYROS

3) Configure the project

The project is created. Now, you have to set it as a «PyDev » and a « Django » project.

clic droit sur le projet / PyDev / set as a PyDev project

clic droit sur le projet / PyDev / set as a Django project

clic droit sur le projet : on doit maintenant avoir un sous-menu Django

clic droit sur le dossier src / PyDev / set as source folder (add to PYTHONPATH)

clic droit sur projet / Properties / Pydev-Django :

  - Django manage.py : src/manage.py

  - Django settings module : pyros.settings

4) Set Code style

Window/Preferences : Pydev / Editor

- Auto Imports : uncheck « Do auto import »

- Code style:

	- Locals … : camelCase

	- Methods : camelCase() with first lower

- Code style / Code Formatter: activer « use autopep8.py for code formatting »

- Tabs : Tab length : 4

(il faudra aussi faire un peu plus loin : https://projects.irap.omp.eu/projects/pyros/wiki/Wiki#Eclipse-only-Set-the-Python3-virtual-environment-as-the-project-interpreter)
