Setup Djangoproject on windows 2012 with Helicon Zoo

Question

We were forced by the company to move our django app from Linux to Windows. I googled and there I found Helicon Zoo is meant to be a good idea to help me setting this up.

I have installed the zoo part as it was described and tried to add my django application which did not work. To be sure I am not having problems with complex stuff in the application I have created a mysite demopage as it was described in the django tutorial so now I have got this folder structure:

C:\inetpub\wwwroot\ZooPythonProject

I have changed the webconfig so it looks like this:

<?xml version="1.0" encoding="UTF-8"?> 
    <configuration> 
     <system.webServer>
      <heliconZoo>
       <clear />
       <application name="python.project">
        <environmentVariables>
                <add name="VIRTUAL_ENV" value="%APPL_PHYSICAL_PATH%\venv" />
                <add name="PATH" value="%APPL_PHYSICAL_PATH%\venv\Scripts;%    PATH%" />
                    <add name="PYTHONPATH" value="%APPL_PHYSICAL_PATH%    \venv\lib\site-packages;%APPL_PHYSICAL_PATH%\venv\lib;%APPL_PHYSICAL_PATH%;% APPL_PHYSICAL_PATH%\mysite" />
                    <!-- <add name="WSGI_APP" value="welcome.application" /> -->
                <add name="CONSOLE_URL" value="console" />
                <add name="DEPLOY_FILE" value="deploy.py" />
                <add name="ERROR_LOG_DIR" value="log" />

 <!-- generic wsgi app -->


 <!-- django project -->  <add name="DJANGO_SETTINGS_MODULE" value="mysite.settings" />

I know that the setting file is taken as if I change the name of the setting file I get a different error message saying that the file cannot be found.

I start IIS and check my logfile it is giving me this error message:

No handlers could be found for logger "django.request"

Does anybody have an idea how to setup this simple django page? It works if I run it without IIS and Zoo and just do a manage.py runserver, but this is not an option for our production server.

Thanks for your help!

Answer 1

The problem may (or may not) come from "zoofcgi.py" script. Sorry for inconvenience anyway. Could you please try a preview release of Zoo v.4 instead: https://github.com/helicontech/zoo/releases It uses different workers for Python application, so your issue may be resolved. Sorry, no documentation yet, but if you already familiar with MS WebPI, then it should be easy to use Zoo for you. After installing it, please, open Applications -> Templates and install "Python sample project". Open it in the browser and there you should find instructions how to put your existing Django project on it.

Sorry, it is still an early beta and applications outside 'Templates' section have not even been tested yet. As I work alone on this project I can't promise fast results, but at least in is open source now and underlying module code that runs applications has not changed significantly, so it is safe to say that if it worked once, then it should work further at least not worse than the previous version.
