Calling a dtml-method that has an extension (Was: Re: [Zope] Creating files on server)

25 Apr 2001

      Hi again,

For secure reasons I have dropped the idea of creating a physical file
on the server. Instead I can create the files dynamically inside Zope
and link to the method.

I have a method called fncSmileGenerate.smil

I call this from another method. Now when doing this I get the following
NameError:

Error Type: NameError
Error Value: fncSmileGenerate

The traceback is this:
Traceback (innermost last):

It seems to me that Zope won't recognize the .smil extension. Is it
possible in any way to make it do so ?
I need the extension because of RealServer.

Hi Gitte,
the built in "open()" is a high security risk and therefore not
exposed to pythonmethods. For this you should stick to
Chris' solution with external method. However keep sure
your script cannot be tricked to write files anywhere on the
filesystem!
Dont use + to concenat pathname parts. Use os.path.join() instead.
Try
os.path.split(os.path.normpath(os.path.join(part,of,your,pathname)))
to see the result of the concenation and if its still in the directory
you want it to be. (someone could feed '../../name' into your script)

Okay maybe I didn't express myself very clear.
Can anyone tell me how I - in somw way - create a file on the

through Zope ?
On the filesystem? LocalFS might be right, read the documentation
for it
(it can eb a bit tricky to find the useful bits from what I
remember ;-)
Failing that, use an external method:
def write_stuff(self,path,stuff):
   f = open(path,'w')
   f.write(stuff)
   f.close()
cheers,
Chris
I have tried the following:
I added a script(Python):
argument list: server, mediafile, tcin, tcout, id, clipname
The code looks like this:
fil = open("/root/Real/Content/" + id + clipname + ".smil", 'w')  
#Open
file
text = "<smil>\n\t<body>\n\t\t<audio src=\"rtps://" + server + "/" +
mediafile + " clip-begin=\"" + tcin + "\" clip-end=\"" + tcout +
"\">\n\t</body>\n\n</smil>"
fil.write(text)
fil.close()
Now when running this script I get a NameError on "open".
What is wrong ?
Regards,
Gitte
