httpresponse from stand alone script
Hi I am calling a stand alone script from within views.py and was able to generate a html file with render_to_string in a stand alone script by include followng line: from django.template.loader import render_to_string now , need to use "httpresponse" to generate a response. is it possible ? tried importing httpresponse and then use "return httpresponse" but got error from "return" as it is a stand alone script and not a funtion. currently, I am writing the result of stand alone script to a file and then render it in views.py. If I could pass some variables to views.py , or if I could use httpresponse in stand alone script , then there was no need of writing to a file and then render the file.

Re: invoking a funcion or module as root
Thank you Jirka, Changed the function to stand alone script and called it with sudo from views.py. that worked and solved my problem. From: Jirka Vejrazka To: django-users@googlegroups.com Sent: Tuesday, August 14, 2012 1:03:29 PM Subject: Re: invoking a funcion or module as root Hi there, you definitely don't want to allow apache to setuid() to root as you've pointed out. You have a few options, probably the easiest one is to write a pair of scripts for each task you want your application to perform with root privileges. - the first script will only contain "sudo " - the second script should contain the necessary step(s) that need to be performed with root privileges. It should be simple to minimize chances for security issues Then you'd configure your sudoers file to allow apache process to call the "second script" *including the right set of parameters* (if applicable) with sudo permissions. You'd then call your "first script" using subprocess() call from your views.py (or whereever appropriate). (you could technically bypass the whole "first script", but it'll greatly improve readability if you do it this way, no one will have to read your python code to match it to your sudoers file if problems occur). Even better solution would be fixing your security model, having a web application perform high-privileged tasks on a system seems flawed in 99% of cases I can think of, but maybe you have a good reason why you need it that way.

invoking a funcion or module as root
Hi I have setup Django with wsgi and Apache on Linux and all is good, but the application that I am building should be able to modify Linux files which are only allowed by root. so, I have created a function named myfunc in a module named mymodule.py and has invoked the function in my application's views.py. now , How can i invoke mymodule.py as root, or is there any way to invoke only myfunc as root ? I already setup sudo , and was able to create directory as root with mkdir command but what about python methods such as open(), how can I open( ) a file as root while funciton is being invoked as apache user ? tried adding mymodule.py and python to a list of commands in suduers file , but still there is a problem with creating the file. even , os.setuid() won't work, because function is being invoked as apache user. thought about setting setuid on python executable, but setuid is not working on scripts and have to write a program in C or C++ and make it setuid and then invoke it through Django and python but don't want to go that way to keep every thing in Python language. the main question is "how to invoke a python function or module as root from view" but I am open for any better solution.

Re: named url patterns - invalid syntax
Thank you for your help
I just learnt about the url funciton but went with
(r'^myform/$', 'mysite.views.myform', {}, 'myform')
as it would be the same as other patterns in urls.py
Thanks again

Because it's syntax is invalid: the 'name=value' is allowed in function calls
but not in tuples.
Try with:
urlpatterns = patterns('',
url(r'^myform/$', 'mysite.views.myform', name="myform"),
...
)

When you use a tuple the syntax is:
(regular expression, Python callback function [, optional dictionary [,
optional name]])
the third element, if present, is expected to be a dictionary. Try with:
(r'^myform/$', 'mysite.views.myform', {}, 'myform')

Re: Writing or editing files using Django
My understanding from template system was: Django template system is to create html files on fly while returning the resulting html to user's browser and the resulting static files would not be saved any where in file system.
