Greetings. I'm developing a Python-based product that needs to serve up a variety of XML files out of the product's directory. That is, certain URLs handled by instances of a product-defined type need to return an XML file that's on disk along with the product's DTML views and the like. Let's say that the URL http://localhost/foo/bar resolves to an object my product class defines. Then I'd like http://localhst/foo/bar/static/a to serve a file named 'a' in a directory named 'xml_files' in my product's directory. Similarly, http://localhst/foo/bar/static/b/c should serve a file named 'c' within a directory named 'b' within 'xml_files' in my product's directory. I'd rather not hard-code every single file in the Python module, since there will be many, and they'll be changing a lot during development. I've been messing around with DTMLFile and ClassicHTMLFile and the like, haven't been able to figure out how to get it to work for arbitrary paths. They also require all my file names end in '.dtml', which is quite a pain. Any suggestions?

I serve static content with FileSystemSite (http://www.zope.org/Members/k_vertigo/Products/FileSystemSite). Sandor

Greetings.
I'm developing a Python-based product that needs to serve up a variety of XML files out of the product's directory. That is, certain URLs handled by instances of a product-defined type need to return an XML file that's on disk along with the product's DTML views and the like. Let's say that the URL
http://localhost/foo/bar resolves to an object my product class defines. Then I'd like http://localhst/foo/bar/static/a to serve a file named 'a' in a directory named 'xml_files' in my product's directory. Similarly, http://localhst/foo/bar/static/b/c should serve a file named 'c' within a directory named 'b' within 'xml_files' in my product's directory. I'd rather not hard-code every single file in the Python module, since there will be many, and they'll be changing a lot during development. I've been messing around with DTMLFile and ClassicHTMLFile and the like, haven't been able to figure out how to get it to work for arbitrary paths. They also require all my file names end in '.dtml', which is quite a pain. Any suggestions?

Local FS? What Sandor said? Apache and rewrite rules? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

I'm overriding '__getitem__' and using Python's "os" package to directly access the local file system. I just sniff the file name extension and set the response content-type, then return the contents of the named file. Simple and stupid. I actually delegate the file-serving to a helper class, and use recursion to handle arbitrary-length paths for arbitrary-depth file system hierarchies. Simple, stupid, and inelegant, but it seems to work. FileSystemSite seemed geared towards providing ZMI access to static files. I just want my product to be able to dish out preset files that are part of the product. (If anyone's curious, I'm using a Zope product for a back-end to a Mozilla/XUL front-end. This static file stuff allows the product to provide the XUL, JavaScript, and CSS files needed to define the Mozilla-based interface.) Thanks for all the suggestions.

Ooo... I hope you're confident in what you're doing :-S Should be vaguely okay, provided you're not writing to those files with the os module. Mindyou, Apache could serve 'em a LOT faster...

Not in the least! =8-0 I've never mucked around this deep within Zope before. What's the danger... threading issues?

No writing, only reading.

It's a whole lot easier to have those files nicely packaged inside my product, so that all someone needs to do is install the product and be done with it. No separate directory of files to put somewhere, no Apache configuration to do, no URL issues. I'm wide open to suggestions for a better way to do this!

I think so! ;-P In the long run, I may set up the XUL/etc. to be installed into the user's Mozilla "Chrome", and then it would be permanently resident. So it would only be downloaded once per user, which makes efficiency less important and Apache (hopefully) unnecessary.

Yeah, but should be okay as you're only reading...

For your stated needs, I think your solution is getting close to optimal :-) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
