Tools used for programming Zope
by Gerald Gutierrez 18 Jan '01

18 Jan '01

I recently looked into Zope in some detail and have decided that it's rather cool, with many features that you don't get from J2EE or ASP or PHP, etc. The Through-The-Web (TTW) aspect of it is interesting, and the documentation seems to infer that this is the direction Zope programming is going, with the use of ZClasses and other features. Unfortunately, I'm a little turned off by the fact that you must edit many things using a web browser. For example, ZClasses were cool and easy to configure through the web, until I discovered that I can't recover the source to it as a source file that I can edit with something else. FSDump only does translation one-way to the filesystem and not back again. DTML can be FTP'ed to the server, but what a hassle this is. So how do people go about programming Zope? What sorts of tools do people use, and how do you go about getting your code to and from Zope? Can you use CVS? Thanks for any help with a newcomer. Gerald.

FW: Variable sort and multiple sort in dtml-in

For example, in an employee > directory, sort on employee name within department. Anyone know how? Hi Loren (sorry for my "approximate english":) There is a good news in this matter. I'v noticed that in Zope 2.3.0b1 was included stricte similar way as my patch. Only names of variables was changed: My name of variable was sort-python, now exists sort_expr Additionally DC guys added reverse_expr variable. Here is a example of use (from my patch but translated to use sort_expr) <dtml-call "REQUEST.set('sortstrvar', _.string.lower('tItLe')+','+'id')"> <html> <pre> 1."Hardcoded" =========== <dtml-in "objectItems(['Image'])" sort=title,id> <dtml-var id>....<dtml-var title> </dtml-in> 2.Indirectly ============ <dtml-in "objectItems(['Image'])" sort_expr="'title,id'"> <dtml-var id>....<dtml-var title> </dtml-in> 3.Indirectly ============ <dtml-in "objectItems(['Image'])" sort_expr="sortstrvar"> <dtml-var id>....<dtml-var title> </dtml-in> 4.Indirectly ============ <dtml-in "objectItems(['Image'])" sort_expr="_.string.lower('tItLe')+','+'id'"> <dtml-var id>....<dtml-var title> </dtml-in> </pre> </html> > I'm trying to provide user-specified sorting on the records I pull from a > SQL database. When the user specifies sorting on Department, I assume he > wants the records order by Name within each department, but I can't see how > to do that with ZSQL or dtml-in. User would specify multiple keys sort (dr Lazarus patch which is included to core from Zope 2.2.2 (?)) eg: <dtml-call "REQUEST.set('usersort', 'department,name')"> <html> <pre> <dtml-in recordset sort_expr="usersort"> <dtml-var department> <dtml-var name> </dtml-in> </pre> </html> But best news for you is that sort_expr patch may be very simply implemented for Zope 2.2.4 and 2.2.5 Simply copy the file: <Zope230b1>/lib/python/DocumentTemplate/DT_In.py to <Zope224|5>/lib/python/DocumentTemplate/DT_In.py thats all you need :) It is possible because nothing else except sort_expr patch was changed in this file, without dependences and influences for other pieces of Zope Best Regards Adam -- Adam Karpierz karpierz(a)alpha.pl

Using images as submit buttons
by richard＠bizarsoftware.com.au 18 Jan '01

18 Jan '01

Has anyone figured a reasonable way of getting multiple image submit buttons for a single form? I tried <input type="image" name="goMethod:method" src="go.png"> but that didn't work for obvious reasons. <button value="submit" name="goMethod:method" type="submit"><img src="images/go.png"></button> didn't work under Netscape 4.75 - I didn't get a button on the form... Suggestions? If nothing is suggested, I think I'll have to suggest that the first form "be fixed". Ick.

zope2.3.0b1 and userfolders
by Bak＠kedai 18 Jan '01

18 Jan '01

hi all it seems that most 3rd party userfolders that's available won't work with zope-2.3.0b1. i've tried UserDB and LoginManager. i guess LoginManager will be updated, since it is currently maintained. i don't know enough python to look at UserDB. any kind hearts out there willing to give it a peek? anyway, where can i find the changes to the security policies from zope 2.2.x to zope 2.3.x ? thanks -- http://www.kedai.com.my/kk http://www.kedai.com.my/eZine Am I Evil?

python-to-python in zope?
by tom smith 18 Jan '01

18 Jan '01

hi all, I've written a bot in python 2.0 and it's running on the same machine as zope 2.2. I'd like somehow to be able to send messages from zope (like...start and stop or go trawl this site etc) to the OTHER version of python running my bot.... I've tried using external methods but because the other version of python has ODBC stuff and Tkinter etc python methods can't "talk" to my app. It errors on import... Should I try to add my bot to the python that comes included with zope (Is it python 2.0?) or does anybody have any better ideas... thanks tom tom(a)othermedia.com

manage_exportObject checks Referer header (RE: [Zope] How to back up Zope data base?) up Zope data base?)
by Mayers, Philip J 18 Jan '01

My earlier suggestion: wget --http-user=username --http-pass=password \ http://server.name/Zope/path/to/folder/manage_exportObject?download%3Aint=1 Does not work (on Zope 2.2.5 at least) but this: wget --http-user=username --http-pass=password \ --header="Referer: http://server.name/Zope/path/to/folder/manage_importExportForm"\ http://server.name/Zope/path/to/folder/manage_exportObject?download%3Aint=1 ...does. Why does manage_exportObject check the Referer header? Is this by design?

Hi all What is the best way to backup Zope's database whithout stopping Zope? When I use backup, it just says that the file is in use and cannot be backed up. What I have done so far is to copy the file in explorer and back that up - but it feels kludgey and I'm not sure if I get the database in a state that is safe.
