Zope, Emacs, and IDEs
by Eron 28 Sep '99

28 Sep '99

Seeing all the traffic on the Zope mailing-list in reference to WYSIWYG editors brought me to wonder a few things (please excuse me if these are redundant questions, but I haven't found any info on them..). * I hear it's possible to edit Zope objects (DTML, etc.) from within Emacs. Is this possible? And if so, is there any way to configure syntax highlighting and do formatting? This honestly would be the only editing tool I need. Is there info on this anywhere? * If it is possible to use Emacs, then what about other text editors? The TEXT form on the browser management screen just isn't what I need when I'm on the server machine. How about using something like the GtkEditor widget wrapped either in PyGTK or WxWindows/Python, where you can have a slim text IDE that can edit, format, and highlight Zope objects, HTML, XML, and python code. Something like Homesite, without all the fluff :-). * Any other ideas, suggestions? I'm building a Zope-based project (called CIS), and would like to eventually integrate some development/administration tools along with the system, that are easy to use yet remain flexible. Issues like these are top on the list of getting other developers to help, so I'd like to find out some options. Thanks in advance. Eron

RE: [Zope] Passing information from a form to an SQL method via a DTML methodd

The variables suddenly disappear > from REQUEST. That's exactly right. The documentation doesn't make it clear that you have to call the ZSQL method with arguments, which is the precise point that I was missing. Does this qualify as a bug in the documentation? Thanks to all Peter.

With the built in Security Model, I can easily prevent customers from viewing other customers' freight information. Some of our customers are competitors among themselves. 2. I just love to program in high level languages. I have tried Java. If my current project gives me more time, I would have used Enhydra. But Zope gives me a few built in tools that I would have to write myself if I were using Enhydra. Why I don't stick to Delphi? Because I only used Delphi to write a small program 2 years ago. I haven't used it since then. Oh yes, I will definitely learn Python :-) Regards, Ping __________________________________________________ Do You Yahoo!?

newbie : dtml-document properties ?
by Geir B Hansen 28 Sep '99

28 Sep '99

Is there a list of standard document properties anywhere ? ( title_or_id , title, id , bobobase_modification_time etc.. ) I bang my head against the wall every day, trying to find the names of standard variables within DTML-methods and documents, and have searched all over to find some reference to this... I have read the 'Zope Document Template Markup Language User's Guide" a hundred times , and scanned monthst of mailinglist-archives , trying to discover these, but i only find the occasional reference to one or two in examples.. ------------------------------------------------ Geir B Hansen geirh(a)funcom.com Web-designer / Graphic artist Funcom Oslo ------------------------------------------------

Accessing Zope DA connection from external method
by Chui.Tey＠env.qld.gov.au 28 Sep '99

28 Sep '99

Jpenny wrote a little how-to about accessing ZSQL Method from External Method. This has really whetted my appetite. At the moment, my external methods create and destroy their connections to the database whenever they are called. This can potentially be expensive when scaling up. Can anyone point out how do I reference a Zope DA Connection from an external method. This way I can make use of an existing open connection instead. Thanks in advance Chui

comparing variables from different name spaces?
by Ainis 28 Sep '99

28 Sep '99

Hello ALL, How do i compare variables from two different namespaces? In my current situation I need to check if my current path is in some directory tree. For example lets say I have folders /test/dir1 /test/dir2 /test/dir3 In these folders there are alot more other folders, so when i currently am in for example /test/dir2/hardware/prices/index_html the script should check in which of those 3 root folders (dir1, dir2 or dir3) am i. Now lets look at the part of /test/dir2/hardware/prices/index_html source: <dtml-with test> <dtml-in "objectValues(['Folder'])">  </dtml-in--> </dtml-with--> Ok, so in this case i have a loop in which i go through ids of all folders in /test/ but now how do I check test's subfolder's id is PARENT of my current /test/dir2/hardware/prices/ folder? I think the easiest way would be- <dtml-if dir2> but that has to be done only from /test/dir2/hardware/prices/ names pace which (i think) I have already lost with <dtml-with test>. So how do I compare the older name space's variable with newer one's? I also tried some tricks with <dtml-with blah only> but with no success. P.S. excuse me if this turns out to be lame question, I'm a bit new to Zope Best regards, Ainis mailto:ainis@mindless.com

Re: [Zope] Allaire Spectra

> Has anyone had a good look at Allaire Spectra? > It looks like Zope on steriods. Or at least marketed that way. Perhaps > someone can do a feature for feature comparrison. Well, features are great for comparing products in a vacuum, but the reality is that few of them make any difference. Architecture, however, can make a world of difference, and that would be more interesting to examine. Certainly Cold Fusion was rather antiquated in its architecture, so... if someone wants to do an architectural comparison, I'd certainly be interested in that, but a feature chart isn't terribly useful.

creating a new file type based on content-type
by Chris McDonough 28 Sep '99

28 Sep '99

Umm.. the message title sort of says it all. I'd like to create a ZClass that represents a certain binary file type (in this case, MS Project .MPP files). I'd like to present the user with the "File" object upload form, but once the submit button is pressed, I'd like the file registered not as a generic "File" but as an "MS Project File" (Zope would tell it is an MS Project file based on its content-type as sent by the remote browser, sort of like it determines if a file is actually an image or an HTML document now). Files uploaded would inherit all the management screens of the MS Project File ZClass... Is this heavy voodoo? (Duh, of course it is, otherwise I wouldn't be asking)... Can anyone give me some ideas of what to change within the Zope source to do this?

I'm not sure if you can get the propertysheet management page DTML through the web. Look at lib/python/OFS/properties.dtml in your Zope distribution...
