Hi You need to pass a file object back, not a string.. So I just patched up your code to return a StringIO file object ( I have not tried it) import sys,os,string from OFS.Image import File import StringIO <======= def get_data: file=open('c:\test.txt','rb') data= StringIO(file.read()) <======= file.close() return data Probably you can pass the f'le object back as well but then somewhere you have to close it/ Regards Sedat -----Original Message----- From: Christophe Bec [mailto:christophe.bec@cgey.com] Sent: Monday, July 09, 2001 5:28 PM To: Sedat Yilmazer Subject: Re: [Zope] Upload a Zclass with a script ok i've tried this external method called get_data : get_data.py ___________________ ___________________ import sys,os,string from OFS.Image import File def get_data: file=open('c:\test.txt','rb') data=file.read() file.close() return data and when icall <dtml-var "REQUEST.set('file',<dtml-var get_data>)"> i 've an error thanks ----- Message d'origine ----- De : "Sedat Yilmazer" <sedat(a)kibele.com> À : "'Christophe Bec'" <cbec(a)capgemini.fr> Envoyé : lundi 9 juillet 2001 16:19 Objet : RE: [Zope] Upload a Zclass with a script IMHO reading a local file via DTML is not allowed. Best workaround is an external python method.

Method reusability
by belen＠netcom.no 09 Jul '01

09 Jul '01

Hello there, I have a method I am using to download a page to a client: <dtml-call "REQUEST.RESPONSE.setHeader('content-ype','application/octet- stream')"> <dtml-call "REQUEST.RESPONSE.setHeader('Content- Disposition','Attachment; Filename='+document+'.html')"> <dtml-return "StepReport(_.None, TestID=TestID)"> But so far I have not found the way to make it reusable, since I have to hard code the parameters I am passing to the document. This means I have to have to create as many variations of the method as pages I want to download. Now I cannot think of any way to make my method recognise or detect how many and which are the parameters I am receiving, since it might vary depending on the document that invokes the method. <dtml-let param_1=param_1....... param_n=param_n > <dtml-var "_['document']"> </dtml-let> <dtml-return "StepReport(_.None, param_1=param_1,...., param_n=param_n )"> Can someone help me please? Thanks in advance, Belen

Zope + LocalFS + Netware?
by Eric Balasbas 09 Jul '01

09 Jul '01

Has anyone tried using LocalFS to access a Novell Netware network drive? I looked at the LocalFS documentation, but there was no mention of Netware. I just want to know if it is possible, and if there is anything I need to know before I try it. The Zope server will be either on a Windows NT 4, or Windows 2000 server.

Setting an image type
by Schmidt, Allen J. 09 Jul '01

09 Jul '01

We have access to images stored on someone else's server. We are able to get to them from a path provided as a field in a database. I prepend the path with the static server address and use the result as an <IMG SRC=> tag. Works great in IE ... not at all in any Netscape except 6. The files are named with number references and no extension. IE can 'see' what the content type is but I guess NS cannot. Is there anyway to tell Netscape that this IMG SRC really is a JPG file and to go ahead and display it? Can I add something to the header though Zope or the DTML-VAR when I display the image? May not be a Zope issue but I figured there may be something Zope can do to the page as it loads. Thanks Allen

Good work. Thanks for letting us know. These path problems aren't always trivial, glad to be of help. Tom P [Schmidt, Allen J.] > Well, I got this to work.

Form-based login/cookies/exUserFolder
by Andy Gimblett 09 Jul '01

09 Jul '01

Hi all, I'm struggling with several aspects user authentication, perhaps someone can help me out? I've tried to put the pieces together myself, but there are big gaps... Firstly, I need form-based login/logout - not a popup window. Am I correct that to do this I need cookie based authentication not basic authentication? If so, why is that? What's the mechanism here? I've been using exUserFolder, and it seems pretty cool - I'm authenticating against a MySQL table and I've been able to write my own authentication routines and plug them in without any problem. But I can't get it to do form-based logins. When you create an exUserFolder it asks if you want basic or cookie authentication, but this seems to make no difference to whether or not I get the basic authentication pop-up box. Does anyone have any ideas or input as to what I'm doing wrong? I've also played a bit with Core Session Tracking, and I'm wondering if and how to integrate that with this process. :-) In particular I want to automatically log people in under certain circumstances. Is CST overkill? Should I just set and look for a cookie in my exUserFolder-based auth routines? But then wouldn't CST be a good way of managing those cookies rather than doing it by hand? All advice appreciated, and if any amazingly kind person wants to discuss this on #zope, I'm there too. :-) Cheers, -Andy -- Andy Gimblett - Programmer - Frontier Internet Services Limited Tel: 029 20 820 044 Fax: 029 20 820 035 http://www.frontier.net.uk/ Statements made are at all times subject to Frontier's Terms and Conditions of Business, which are available upon request.
