This is not straightforward for a file, and esp. not a zope thing/problem. By default, the browser uses the tail of a URI to construct the filename for saving. Additionally, most browser honor a http-header which looks like Content-Disposition: attachment; filename="filename.ext" which would cause the "save as" box to display "filename.ext" as filename. Now we need to get zope to return this header for an object of type file. Fortunately, a file has a property called "precondition". We use that to call a python script to set the right header. So put the following line in a python script above your files in the hierachy: context.REQUEST.RESPONSE.setHeader('Content-Disposition','attachment; filename=' + context.title) call it "setheader" and use setheader as precondition for your files. cheers, oliver ------------------------------------------------------- where can i find information about setting precondition for files ?? i tried to search on the zope.org but its useless. Thanks, Sanju. __________________________________________________ Do You Yahoo!? Send your FREE holiday greetings online! http://greetings.yahoo.com

MailHost problems
by Tony Flanagan 07 Dec '01

07 Dec '01

hi all, I am currently using the MailHost product in zope to send automatic e-mails from my Zope site, via the companies e-mail server. This was working perfectly on my own machine(Win 98), but when the site was moved onto an NT server I've started getting the following error, without a traceback.. Error Type: SMTPHeloError Error Value: (501, 'Invalid domain name') Does anybody know what causes this. The server name I've used is correct,and I am able to ping it from my NT server. Any help is greatly appreciated, Best Regards, Tony.

Creating a class in a python script
by Ronald L. Chichester 07 Dec '01

07 Dec '01

If I put the code... class myErrorClass: element_number = -1 ... and then later... an_Error = myErrorClass() return an_Error ... I get an error message when the custom class is instantiated and/or returned. Can I not create classes within a python script? Thanks in advance, Ron

zope and mod_rewrite

Re: Zope Solution

What about speed in this system, is it comparable with CORBA?. We have designed our system such that we need callbacks, id. e sending a request to the server requires the server to call the client again. Is this possible with the xmp-rpc model. regard, Geirt Arne On Thursday 06 December 2001 23:42, you wrote: > Hi! > > You're right, as Stephan answered to you we used in this project Zope as > a pure 'blind' appserver. > > the protocol we used there is xmlrpc (www.xmlrpc.com) which has bindings > for nearly all languages, among these: python,c++,java on client and > serverside. xmlrpclib marshalls function calls and basic types > (scalars,dicts,lists,datetimes) as xml statements and uses http as > transport. > > Zope has a built-in xmlrpc server. > > There are also projects for other protocols (SOAP and CORBA) but I think > the latter one is in an experimental state. > > The point I liked so much about xmlrpc was that is very uncomplicated to > implement. > > As I can read from your explanation it should be well possible to > implement that with Zope. > > Please let me know when you need more information, perhaps you can then > provide me more details about your project . > > > regards > > phil > > Am Don, 2001-12-06 um 13.59 schrieb Geir Arne Evjen: > > I posted this message in Zope's miling list.

Web reporting
by Jeff Sacksteder 07 Dec '01

07 Dec '01

I have recently been generating web reports from relational data in our ERP system and would like to process the results a little more than what I can accomplish with SQL alone. Are there any reporting packages available for Zope that are similar in spirit to Crystal Reports or anything like that? I'd like to have a few basic functions like sum and average, etc. I could do this in python, but I would think this kind of thing should be a Product that everyone can use. Does such a thing already exist somewhere?

Authentication by IP address
by Arian de Wit 07 Dec '01

07 Dec '01

Hi All, I'd like all users browsing the site from 192.168.*.* (i.e. our intranet) to see some additional content. I've read and implemented the HowTo (although * isn't allowed in IP addresses, apparently) and then found via the mailing list archives the "setAuthenticationMode" thing to actually make it work, and only then discovered that it takes *much* longer for pages to load under this scheme. Is there some other way to achieve my goal? Basically, I want intranet users to see an "update/correct this page" form at the bottom of every page, in an effort to help them to help us keep our content fresh and accurate. FYI, I am running Zope 2.4.2 with ZServer on Win2K Server SP2.
