strange bug with mail&redirection
by Joerg Wittenberger 14 Sep '99

14 Sep '99

Hello folks, I've got a code snippet, which seems to reveal at least one bug: I have a dtml method, which receives a form input and either a) tries to transfers control to another method, if it's there or b) changes some properties and redirects to another form: <dtml-try> <dtml-var "_['t' + `status` + 'to' + `REQUEST.form['status']`]"> <dtml-except> <dtml-call "propertysheets.manage_changeProperties(REQUEST)"> <dtml-call "RESPONSE.redirect(URL1 + '/edit')"> </dtml-try> now I have another dtml method "t5to6", which sends some mail and shares the rest of the operation:  To: jerry@localhost From: Transition Subject: STATUS: <dtml-var title> <dtml-var number> 5 -> 6 Statusübergang  <dtml-call "propertysheets.manage_changeProperties(REQUEST)"> <dtml-call "RESPONSE.redirect(URL1 + '/edit')"> Problem I (less hard): Sometimes all I do is edit the "t5to6", after that I get the message "AttributeError" __call__. I can solve that by deleting and recreating the dtml method. Problem II (real part): The method sends mail at most one time, but most of the time I see an error "Invalid Header 0:" from DTMLMethod.py line 398. I don't get that error when I either don't redirect or don't send mail. (Using mailhost instead of smtphost won't help.) /Jerry -- You can have it done fast, you can have it done cheap, and you can have it done well. --- But you can only have two of those at once.

ZClasses and Properties (Q1959)
by picasso＠videotron.ca 14 Sep '99

14 Sep '99

Hi, I try to understand the Zen of ZClasses. As i understand it: - attributs listed in the "Basic" tab, are those of the whole Class and (the values are the same for all the instances of a class) - attribut values of the Property Sheets are specific for each instance. I'm a right or wrong?

Yet another: How do I create linked path trails as per zope manag ement interface? ement interface?
by Andrew Bunney 14 Sep '99

14 Sep '99

I really like the trails of links that show the path to a document which allow you to jump up the hierarchy These appear on the Zope Management Interface. As a real newbie (with no really programming knowledge) I can't work out how to do this and can't find any info on it. An added complication (possibly) is that it may well be served via an external webserver. Can anyone let me have a code snippet?

Re: [Zope] How do you do the printable page link as per Zope site standard footer?ooter?

Check out these links: http://www.zope.org/dtml_source?path=/standard_html_header http://www.zope.org/dtml_source?path=/standard_html_footer You'll notice that the Printable Page link on the Zope.org site will take you to, for example, index_html?pp=1 In the header and footer, much of the page layout is enclosed within:  header/footer stuff  So, the Printable Page link basically just goes to the same page but sets the variable "pp" to 1. Then, the header and footer will avoid sending most of the layout. Kevin

More newbie questions: can't find object by ID?
by Scott Anderson 14 Sep '99

14 Sep '99

Hi all (again), Here's my code: DTML Document at /Reporting/Admin/report_management.html   <table> <tr><th>ID</th><th>Report Description</th></tr>  <tr> <td></td> <td></td> </tr>  </table>  <BR><BR> There are no defined reports at this time. <BR><BR>   tblReportType is a SQL Method: Z SQL Method at /Reporting/Admin/admin_sql/tblReportType tblReportType has been tested and it works fine, returning two records. However, the above document returns only "There are no defined reports at this time." If I remove the '#if' tags, I receive: Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: tblReportType Why is Zope not finding the SQL Method? Thanks, -scott

Turning off direct access to ZServer in 2.0
by Jim Sanford 14 Sep '99

14 Sep '99

I am using Zope 2.0 with IIS4.0 (for SSL) via pcgi. IIS is set to anonymous (no Basic or NT authorization) and all authorization is being handled by Zope. The default.htm page in IIS immediately forwards users to my primary Zope object which triggers the authentication. How can I restrict users to only accessing Zope through IIS.? Is there someway to turn off ZServer or better yet only have it accessible by a few select accounts for management purposes? Jim Sanford Accelearated Technology, Inc.

Some databases may expose this information in a special object. If it's a selectable object (not a stored procedure), it's easy to get the information. But by default, most databases don't return any information about how many rows were affected by a statement. And those that do probably don't do it in a uniform way.

SQLMethods: getting # of rows updated

When a SQLMethod is called that modifies data through an UPDATE or INSERT statement, is there any way of finding out how many rows were affected by the change? -- A.M.
