Create a new project

You can start a django app by:

  cd my-dj-project-folder 
  django-admin.py help startapp 
   django-admin.py startapp my-app-folder 
  # a it needs always __init__.py!!!!

To let a django application get to work, you need (in general) the following files:

__init__.py   (a 0Byte file needed by python) 
url.py  (URL pattern definitions) 
models.py  (data-model definitions) 
views.py  (view layer: form request definitions, form processing) 
mytemplate.html  (a template to process, see also admin/doc/) 

Create first model

After setting the database a first autgenerated model can be obtained by

 cd /artenquiz/django/artenbestimmung
 python manage.py inspectdb
 python manage.py inspectdb > models_autogenerated.py
 mv --interactive  models_autogenerated.py models.py

Change translations

(1)

<!-- in /templates/mytemplate.html -->
  {% trans "Short localised message" %}
  {% blocktrans %}Localised message 
  spanning multiple lines{% endblocktrans %}
<!-- in /templates/mytemplate.html -->

(2)

# move to base directory of artenquiz app 
cd /artenquiz/django/artenbestimmung
django-admin.py help makemessages # show the help
django-admin.py makemessages --no-wrap -l de --extension='.html,.txt' && django-admin.py makemessages  --no-wrap -l en --extension='.html,.txt'

(3) Add translations at least in

• /artenbestimmung/locale/de/LC_MESSAGES/django.po
• note that #, fuzzy becomes not translated, you may remove it and make sure you have an exact msgid or change it to #, use-fuzzy (?undocumented hack? because msgfmt has msgfmt --use-fuzzy)

(4)

# move to base directory of artenquiz app 
cd /artenquiz/django/artenbestimmung
django-admin.py compilemessages

(5) (eventually) restart the server

sudo /etc/init.d/apache2 help
# [ ok ] Usage: /etc/init.d/apache2 {start|stop|graceful-stop|restart|reload|force-reload|start-htcacheclean|stop-htcacheclean|status}.
sudo /etc/init.d/apache2 restart

Install other modules
