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/team

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)

h3. Create a Python3 virtual environment dedicated to the project (inside the project folder)

<pre>

$ mkdir private/

$ cd private/

$ which python3.5 ("where python" for windows)
/opt/local/bin/python3.5

$ virtualenv-3.5 venv_py35_pyros -p /opt/local/bin/python3.5
=> creates a venv_py35_pyros/ folder inside PYROS/private/

</pre>

---

h3. Activate the python virtual environment (from inside the project)

<pre>

$ pwd
.../PYROS/private

$ source ./venv_py35_pyros/bin/activate (venv_py35_pyros/Scripts/activate on Windows)

$ python -V
Python 3.5.1

$ which pip
