eCommerce with Zope
by Ragnar Beer 24 Feb '01

24 Feb '01

Howdy! I wonder how on-the fly verification of e.g. credit cards or whatever else verification that could take some time can be done using Zope if Zope doesn't support multipart content. As a user I'd expect to get an immediate feedback like "verifying your credit card ... (please wait)" or "checking whether this domain name is available ..." and then after a while see the results without any further action. This is would be a typical job for multipart content-type, wouldn't it? Is there a workaround or so to get this done with Zope? Ragnar

You might try something like this, in an external method, to capture the HTML, and then insert it as the body of the message: #! python """ urlgrabr.py is a simple script to hit an URL, retrieve the generated output, and manipulate it, including stripping out extraneous line feed characters. e.g. save Web page as a file, python urlgrabr.py someURL file=somename.htm based on parameters. Default is simply to call the URL, and exit, dumping all data.

side sorting
by Spinwing 24 Feb '01

24 Feb '01

Hello Oliver it worked perfectly for me but consider the following: - I have set an atribute different from the "sort" name, just to be sure to avoid conflicts, so I named it "sort_order" - my dtml statement looked like: <dtml-in expr="objectValues('Folder')" sort=sort_oder> this way it works. Hope to be of help Rgds Stefano Message: 44 Date: Fri, 23 Feb 2001 17:22:27 +0100 From: Oliver Vecernik <vecernik(a)aon.at> Organization: VECERNIK Datenerfassungssysteme To: "zope(a)zope.org" <zope(a)zope.org> Subject: [Zope] side sorting Hi, I have following DTML method for a sidebar construction: <ul> <dtml-in expr="objectValues('Folder')" sort="_.[sort]"> <li><a class="sidemenu" href="&dtml-absolute_url;"><dtml-var title_or_id></a><br></li> </dtml-in> </ul> I set a property named 'sort' to every folder, but my code doesn't work.

User logoff
by Bodo Bauer 24 Feb '01

24 Feb '01

Hi, it seems like a simple question, but I didn't any mentioning on zope.org. Which function has to be called to log off Zope once you're authorized with the system? I'd like to have a 'logoff' button on my site that allows to log off and i.e. log on as another user from the same browser.

How to define a default security profile for ZClass instance?
by Dirksen 24 Feb '01

24 Feb '01

Hi, I'd like to have instances of my ZClass deny the rights of 'access content information' and 'view' from anonymous users, as soon as they are created. It's as well desirable to be able to change the ZClass instances' security profile at one stroke. An usual solution would be to create a folder with those settings to house the ZClass instances. Yet my ZClass instances are required to scatter around in my site, thus I need unusual solutions. I played with the 'Define Permissions' tab for the ZClass definition, but only to find out any modification there doesn't seem to have any effect on the instances. Any clues, suggestions are welcome!

Re: [Zope] DCOracle and chars over 128

We have had similar problems. However, it had nothing to do with DCOracle but with the Oracle client library configuration. You can tell it about the character set the client should use. Dieter

Help eMail this page to a friend
by Loren Stafford 24 Feb '01

24 Feb '01

I'm trying to make a global method to implement the "eMail this page to a friend" function I've seen on many sites. (Surely someone has already done this for Zope, but I don't see How-To or email on the subject.) What I have so far is this: <dtml-with "PARENTS[-1]"><dtml-sendmail mailhost=MailHost> To: <dtml-var eMailThisPageTo>@morphics.com Reply-to: <dtml-var "AUTHENTICATED_USER.getUserName()">@morphics.com From: webserver Subject: <dtml-var URL1> <dtml-mime type="text/html" encode="7bit"> <dtml-var "REQUEST.resolve_url(URL1)"> </dtml-mime> </dtml-sendmail></dtml-with "PARENTS[-1]"> But it just emails the text of the method that called it. E.g. <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <ul> <li><a href="http://helpdesk/">"Perfect Tracker" Help Desk</a> </ul> <dtml-var titlelist> <ul> <li><a href="http://search.support.microsoft.com/kb/c.asp?fr=0&SD=GN&LN=EN-US" >Microsoft Technical Support</a>. </ul> <dtml-var standard_html_footer> How do I make it render (i.e. process the DTML in) the method that called it? -- Thanks -- Loren
