h3. Create database

One liner:

$ mysql -u root < pyros.sql

Or :

$ mysql -u root

mysql> create database pyros;

mysql> use pyros;

mysql> source pyros.sql;

(

TODO:

mysql> grant all on pyros.* to pyros@localhost identified by ‘pyros’;)

mysql> flush privileges;

)

---

h3. Install python3.5

$ sudo port install python35

---

2) create project dir

$ mkdir pyros

Exemple de bonne organisation :

1 projet = N applis

(mais 1 appli peut faire partie de plusieurs projets)

MONPROJET/

	src/

		monprojet/

		appli1

		appli2

		…

		appliN

	public/

	private/

		requirements.txt

---

3) Set needed folders (inside pyros/)

$ mkdir private public

$ mkdir public/static

---

4) create virtualenv with python3.4 dedicated to pyros project

$ cd pyros/

$ which python3.5

/opt/local/bin/python3.5

$ virtualenv-3.4 venv_py35_pyros -p /opt/local/bin/python3.5

=> creates a venv_py35_pyros/ folder inside pyros/

5) Activate venv and install needed python packages

$ source venv_py35_pyros/bin/activate

$ python -V

Python 3.5.1

$ which pip

…/pyros/venv_py35_pyros/bin/pip

6) Create django project pyros

$ django-admin startproject pyros

$ tree pyros/

pyros/

├── manage.py

└── pyros

    ├── __init__.py

    ├── settings.py

    ├── urls.py

    └── wsgi.py

$ mv pyros src

$ cd src/

$ ./manage.py runserver

(ou gunicorn pyros.wsgi)

==> http://localhost:8000

8) Set Database mysql

Edit src/pyros/settings.py

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.mysql',

        'NAME': 'pyros',

        'USER': 'root',

        'PASSWORD': ''

    }

}

9) Import database into django

cd src/

$ ./manage.py inspectdb > models.py

Traceback (most recent call last):

  File "/Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/django/db/backends/mysql/base.py", line 25, in <module>

    import MySQLdb as Database

    import _mysql

ImportError: dlopen(/Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/_mysql.cpython-35m-darwin.so, 2): Library not loaded: libmysqlclient.18.dylib

  Referenced from: /Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/_mysql.cpython-35m-darwin.so

  Reason: image not found

=> BOUH !!!

LA SOLUTION EST ICI : http://stackoverflow.com/questions/6383310/python-mysqldb-library-not-loaded-libmysqlclient-18-dylib

(

Apparemment, ceci aurait dû suffire:

mkdir -p /usr/local/lib   

ln -s /usr/local/mysql/lib/libmysql* /usr/local/lib

)

Mais j’ai fait ceci:

$ otool -L /Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/_mysql.cpython-35m-darwin.so

/Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/_mysql.cpython-35m-darwin.so:

	libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

	/opt/local/lib/libssl.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)

	/opt/local/lib/libcrypto.1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)

$ locate libmysqlclient.18.dylib

/Applications/XAMPP/xamppfiles/lib/libmysqlclient.18.dylib

/Library/SystemMigration/History/Migration-68137DFB-CB6A-4FBB-81E2-11BDB5D01E48/QuarantineRoot/usr/lib/libmysqlclient.18.dylib

$ sudo install_name_tool -change libmysqlclient.18.dylib /Applications/XAMPP/xamppfiles/lib/libmysqlclient.18.dylib /Users/epallier/Documents/_W_more/PROJECTS/GFT/SOFT/PYROS/pyros/venv_py35_pyros/lib/python3.5/site-packages/_mysql.cpython-35m-darwin.so

$ ./manage.py inspectdb > models.py

=> YES !!!

10) Create a django application pyrosapp

$ ./manage.py startapp pyrosapp

$ tree src

│   ├── __pycache__

│   │   ├── __init__.cpython-35.pyc

    └── views.py

11) Replace the default pyrosapp models.py with the inspectdb generated one

$ mv models.py pyrosapp/

TODO :

12) Fix and improve the inspectdb generated file models.py

$ cd pyrosapp/

$ vi models.py
