home.pl & django - pierwsza potyczka

by Marek Wywiał
  |   Source

home.pl obsługuje pythona jako cgi (pliki .py) więc tego będziemy się trzymać. Instalację wykonamy w katalogu /py

instalacja django

hardcoded ale działa ;) wrzucamy to do /py i ruchamiamy poprzez www (plik install.py)

 #!/usr/bin/env python

 import os

 os.system("wget http://www.djangoproject.com/download/1.0.2/tarball/")
 os.system("tar zxf Django-1.0.2-final.tar.gz")
 os.system("rm Django-1.0.2-final.tar.gz")
 os.system("mv Django-1.0.2-final tmp")
 os.system("mv tmp/django django")

nasz projekt

Lokalnie wołamy

$ django-admin.py startproject pytest

i wrzucamy katalog pytest przez ftp na home do katalogu /py .

 # Change this to the directory above your site code.
 sys.path.append("/py")

 # Change mysite to the name of your site package

 run_with_cgi(django.core.handlers.wsgi.WSGIHandler())

i odpalamy to by www :D na razie tyle ...
