home.pl & django – pierwsza potyczka
hosting, python, webdev 26 lutego 2009, 21:02home.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
cat 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 .
dispatcher.py
cat dispatch.py
#!/usr/bin/env python
import os, sys
import django.core.handlers.wsgi
def run_with_cgi(application):
environ = dict(os.environ.items())
environ['wsgi.input'] = sys.stdin

if environ.get('HTTPS','off') in ('on','1'):
environ['wsgi.url_scheme'] = 'https'
else:
environ['wsgi.url_scheme'] = 'http'
headers_set = []
headers_sent = []
def write(data):
if not headers_set:
raise AssertionError("write() before start_response()")
elif not headers_sent:
# Before the first output, send the stored headers
status, response_headers = headers_sent[:] = headers_set
sys.stdout.write('Status: %s\\r\\n' % status)
for header in response_headers:
sys.stdout.write('%s: %s\\r\\n' % header)
sys.stdout.write('\\r\\n')
sys.stdout.write(data)
sys.stdout.flush()
def start_response(status,response_headers,exc_info=None):
if exc_info:
try:
if headers_sent:
# Re-raise original exception if headers sent
raise exc_info[0], exc_info[1], exc_info[2]
finally:
exc_info = None # avoid dangling circular ref
elif headers_set:
raise AssertionError("Headers already set!")
headers_set[:] = [status,response_headers]
return write
result = application(environ, start_response)
try:
for data in result:
if data: # don't send headers until body appears
write(data)
if not headers_sent:
write('') # send headers now if body was empty
finally:
if hasattr(result,'close'):
result.close()
# Change this to the directory above your site code.
sys.path.append("/py")
# Change mysite to the name of your site package
os.environ['DJANGO_SETTINGS_MODULE'] = 'pytest.settings'
run_with_cgi(django.core.handlers.wsgi.WSGIHandler())
i odpalamy to by www 
na razie tyle …
Dokładam paczkę z plikami do testu:
unzip py.zip; ftp na home.pl; open http://server.home.pl/py/dispatch.py/admin
) przez Google.
