RE: [Zope] Preserving Settings during a user's session

Amazon has accomplished this by providing a post request variable. ie www.amazon.com/?4834938348934 Go to their site and look at the method. It is fairly straight forward. They use an identifier that is dynamic per user across sessions. The accomplish it via cookies and consistently using the uid(userid) variable in the same location. Zope has an advantage here because you can reference the cgi request variables without CGI: ZOPE DOCS: http://www.zope.org/Documentation/Guides/DTML/DTML-HTML/DTML.html#29461 use the QUERY_STRING variable to save session variables. use cookies to save the id across sessions. <---The combination is Amazon's Solution Just a thought. 2cents worth!

Var Includes:Extension
by shawh＠sths.org 24 Feb '99

24 Feb '99

Well, I gave up on a DTML only method, and wrangled with Extensions till I got it right: Here's the code, in case anyone's interested. from string import split def getbypath(ob, path): """Return an object as directed by 'path'""" parent=None current=ob for i in split(path, "/"): try: parent=current current=getattr(current,i) except TypeError: return "Encountered Exception" parent.temp_child=i return parent And here's the DTML that calls it:      Of course the real DTML would have some variable in place of 'index_html'! note: the simplest and most obvious course (to me) gave poor results. If the Extension method returns 'current' then you get the equivelant of a '#var ... urlquote' where not even the DTML is evaluated. The mucking about with 'parent' and 'temp_child' is necessary to bring it in properly pre-evaluated. But now it works fine. Thanks to all who helped.

The FORM's ACTION determines where all INPUT TYPE="SUBMIT" buttons send the form. Alternatively, you may try adding a little JavaScript and changing the button to: <INPUT TYPE="BUTTON" VALUE=" Go! " onClick="somefunction(this.form)"> in the JavaScript function: somefunction(form) you can change the ACTION property of the form based on which button was clicked.

Is there any nice automated way in Zope to make a form with multiple submit buttons each calling a different document? Currently I have hacked around this by calling a single document containing a deeply-nested conditional and some  includes but this is giving me obscure errors and anyway is messy. --- Julian Morrison Programmer (Zereau Ltd)

Var includes
by Shaw, Howard 24 Feb '99

24 Feb '99

This is my current code          the 'extra_pages' is an SQL query returning location='rochaj/studinfo' where the rochaj is a directory name and the studinfo is a Document in that folder. It is key that there may be an arbitrary number of directories before the final Document is specified. What I need is some command to put in place of the 'call REQUEST' which will put me in the namespace of a folder in the current folder, i.e. move me one deeper into the hierarchy, but without requiring an open and close tag, since they won't operate properly inside of an 'in' loop. Please help.

RE: [Zope] Var includes
by Shaw, Howard 24 Feb '99

24 Feb '99

Well, I thought this would do, so I let it sit while I built a new webserver. Now I am back to work on Zope, sitting on my new server, and I find that I'm not sure I fully comprehend these instructions. What I need to do, is to 'include,' in the same way the default document says '' a document whose location I receive from an sql query in the form of 'dir/dir/dir/.../file' with an arbitrary number of directories. It is not an object whose namespace I need to enter. Rather, I need to get into the namespace of the last dir, so I can #var include the file.

ANNOUNCE: Zope 1.10.2 release
by Amos Latteier 24 Feb '99

24 Feb '99

Hello Zopesters: I'm pleased to inform you that Zope 1.10.2 has landed: http://www.zope.org/Download/Releases/Zope-1.10.2/ This release fixes a number of bugs since 1.10pr1. The only user-visible change is that there is now a management interface for importing and exporting objects. You can find out more by visiting the change log. http://www.zope.org/Download/Releases/Zope-1.10.2/Changes Why the jump from 1.10pr1 to 1.10.2? Because we kept finding and fixing small bugs just as we were ready to make a release. Check the change log for the gory details. We believe that this release is pretty solid and hope to not make another stable release for a while. Have at it and have fun! -Amos -- Amos Latteier amos(a)digicool.com Digital Creations http://www.digicool.com

Did any of you folks out there know that the Pack operation makes a backup copy of your database file? (Did any of you know there was a Pack operation? :^) Anyway, you could automate a pack that says something ridiculous, like pack anything older then one thousand days. Pack will create a Data.bbb.old backup copy of your file before packing. This Data.bbb.old will have no processes that have it open so you should be able to back it up just fine. Or possibly, none of the above will work and it's total hogwash. :^) --Paul

ZServer (FTP): socket.error: host not found
by Oliver Thuns 24 Feb '99

24 Feb '99

If I start ZServer under Windows I get the following error ind the ftp_server module. This can be easily fixed by changing line 57 and inserting the IP, but this is not very nice. Could you fix this? Traceback (innermost last): File "start.py", line 20, in ? import ZServerFTP File "ZServerFTP.py", line 158, in ? from medusa.ftp_server import ftp_channel, ftp_server File "medusa\ftp_server.py", line 57, in ? IP_ADDRESS = socket.gethostbyname (socket.gethostname()) socket.error: host not found
