http file download method
by Giuseppe Bonelli 14 Dec '04

14 Dec '04

Hi list, I have a small python product to download files via http. For various reasons (e.g. to have per user log files and for other security issues) I read the files from the file system and then stream them using a method. Here is a code snippet: class container(Folder): "general container" ... def getFile(self, fname, REQUEST): "read a file from the filesystem and stream it through http" user=str(getSecurityManager().getUser()) userDir=userDirs[user] logFilePath=userDir+'downloadLog.txt' logFile=open(logFilePath, 'a') userDir+='download\\' path=userDir+fname f=open(path, 'rb') cnt=f.read() f.close() res=REQUEST.RESPONSE (type, enc)=guess_content_type(name=fname, body=cnt) res.setHeader('content-type', type) res.setHeader('content-length', os.stat(path)[6]) res.setHeader('last-modified', os.path.getmtime(path)) res.setHeader('accept-ranges', "none") res.write(cnt) s='%s\t%s\t%s\n' % (user, strftime("%A %d %B %Y - %H:%M", localtime()),fname) logFile.write(s) logFile.close() The method getFile is called from the web passing the fname parameter in the url, e.g http://foo.bar/getFile?fname=xxx.xxx Everything works nicely, but obviously on the download dialog box displayed by the client browser you get the name of the download method "getFile" instead of the name of the file and this can confuse some users. Any ideas to resolve this? TIA, __peppo

ZFSPath Product.
by Jason Leach 14 Dec '04

14 Dec '04

hi, With ZFSPath product I can save a fille (a ZIP) and open it, but I can't 'open with' when I click on it; it shows up as an empty ZIP file. Any idea what's up with that? I am setting a few headers along the way: results = container['sqlSelectProductByMD5'](md5hash=id).dictionaries()[0] container.REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip') container.REQUEST.RESPONSE.setHeader('Content-type', 'application/octet-stream') container.REQUEST.RESPONSE.setHeader('Content-transfer-encoding', 'binary') container.REQUEST.RESPONSE.setHeader('Content-disposition','attachment;filename=%s-%s.zip' % (results['license'], results['level'])) container.REQUEST.RESPONSE.setHeader('Content-length',len( container.reports['outgoing']['%s-%s.zip' % (results['license'], results['level'])].bytes())) return container.reports['outgoing']['%s-%s.zip' % (results['license'], results['level'])].bytes()

DTMLFile from products
by massimop＠users.berlios.de 13 Dec '04

13 Dec '04

Hi, I'm experimenting with products an I'm finding challenging to serve a javascript file from the context of the product. I've simply defined a function def posts_js(self): """javascript file""" return DTMLFile('dtml/posts.js', globals()) The file is served but some chars are substituted by entity, so if I have if (i < 10) { I get if (i < 10) { and the browser dislike it... I need something like 'structure' of ZPTs, but I don't know how to use it from products, and however I suspect it could be useless cause the function return an object (am I right?). thanks for any hint massimo

Re: [Zope] 'id' an ilegal folder name?

You can have 'id' in the URL, e.g. /countries/asia/id if 'countries' (or 'asia') is an instance of Path Handler Ken Ara --- In zope(a)yahoogroups.com, Jaroslav Lukesh <lukesh@s...> wrote: > Dne sobota, 4. prosince 2004 18:33 Duane Raymond napsal(a): > > I've created a folder for each country with the 2 letter country code > > as the folder name.

'id' an ilegal folder name?
by Duane Raymond 13 Dec '04

13 Dec '04

Hi, I've created a folder for each country with the 2 letter country code as the folder name. However I keep getting an error with Indonesia - country code 'id'. Given it's use across Zope - is these a reserved word and thus can't be used for naming - or just an edge case no one has encountered before? (I'm using Zope 2.7.x with Plone 2.0.4) Cheers, Duane

RE: [Zope] DTML vs ZTP
by Andy Yates 13 Dec '04

13 Dec '04

I started out using DTML. I have since switched to page templates. Now the only place I use DTML is in ZSQL methods. The Zope Book states the advantages of ZPT clearly http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/ZPT.stx So far I've never run in to anything I did in DTML that I could not do in ZPT. If I were you I'd learn just enough DTML to use ZSQL methods and concentrate on ZPT. For me the biggest advantage of ZPT is keeping the programming logic out of the html.

As you can appreciate, in learning a new technology, what is missing is the experience that would guide your focus. What I would like is an idea of how real world developers use these in the following senses. Do you use one exclusively (in conjunction with Python)? Do you use primarily one or the other? Do you use both roughly equally? Are there classes of applications where you have found one is preferred? Your advice would be welcome.

Can't add Python processes
by Ken Ara 13 Dec '04

13 Dec '04

Hello all, After reinstalling Zope I have only one active Python process. (The parent process is also running but uses no CPU time.) I think this must be negatively affecting performance. Zope 2.7.3-0 Python 2.3.4 (Final) In zope.conf under zserver-threads, I first did nothing, leaving the default. Then I tried different values: 3, 7 and 10 with no effect. Zope 2.7.3 (unreleased version) was running fine before, with four threads. I needed to reinstall Zope because I had lost and reinstalled Python 2.3.4. During this latest install, Zope identified my new Python as 'optimal'. Both zopectl and runzope correctly set CONFIG_FILE to my zope.conf. FWIW, debug-mode is off. What am I overlooking? Thanks, Ken __________________________________ Do you Yahoo!? Read only the mail you want - Yahoo! Mail SpamGuard. http://promotions.yahoo.com/new_mail

Startup
by Jason Leach 12 Dec '04

12 Dec '04

hi Zope: Is it possible to have a 'startup script' type of mechanism for a virtual site? I think ASP has one, it allows some things to be setup the first time a site is accessed. For example I would like to create a transient object folder in my /temp_folder to hold session data for each particular site; this has to do with my custom session start/end scripts. Thanks, J.
