Also, does Emacs' HTML mode handle DTML well? Long discourse here. Warning: I'm not a talented Zope developer, not a talented developer of any kind, and not a horribly sophisticated Emacs/XEmacs user. I love Emacs. I'm using XEmacs a lot these days, but I'll just say Emacs. I've badgered Amos for two months now about getting EFS support working -- for me, Nirvana would be editing Zope directly from Emacs. Why is it so cool? Let me describe how it works first for those that don't know Emacs or ange-ftp/EFS. Yesterday I ran ZServer from my sandbox and fired it up with HTTP on port 9211 and FTP on port 9210. I then went into XEmacs and asked it to open the "directory": /someuser@somemachine#9210:/PaulStuff/ provided my login information stored in an acl_users folder and blam, there was a "directory listing" of all my stuff. I visited a test.html file, it loaded into a buffer and HTML mode turned on, colorizing my tags. I made a change and saved the "file". I then went into Netscape, pressed refresh on test.html and saw my changes. Beyond that it gets cool. You can mark twenty things on your hard drive and load them into Zope or vice versa. Presumably you could copy things from one Zope to another. You can use the excellent diff tools to see changes between a local version and a remote version or apply a patch sent to you by someone. If you make a mistake you can go into Zope and undo the changes. Ultimately there are some deep flaws with this. First, it's still FTP under there. FTP is security challenged, but more than that, it isn't an object system. How, via FTP, would you add a property to a folder? Change the security? Indicate a DTML syntax exception? Review the posts in a discussion folder? FTP is not part of the "web object model". There are some other "gotchas" as well. The current DTML syntax does not lend itself to playing nice with HTML editing modes in FTP clients such as Emacs, Dreamweaver, etc. Anyway, that's some of my thoughts on the subject. --Paul

Unfortunately no, and I can't see one on the horizon. Writing ODBC drivers is painful beyond all recognition from what I'm told. A more realistic idea couple of ideas would be to implement an ADO interface. Alternatively, create a Delphi object that embedded Python and some various Zope "clients", such as WebDAV, Z RPC, XML-RPC, etc. --Paul

Help me to be zennish
by Tom Deprez 23 Apr '99

23 Apr '99

Hi, I'm reading through the documents, but I've some problems getting the Zen : In the document 'Zen of HTML methods' you tell : Folders provide a rendering context for Documents. When you view a document, you are viewing it within the context of its folder. (Rendering Context) --> This means, in my opinion, Documents, inherite the layout (or the variables) of the folder they are in. But then : A Document is a lens through which the Zope object system can be viewed. (Documents are Templates) --> But as a document inherites from a folder... then isn't the folder the lens through .... (hack, probably my bad english which is giving me problems) Tom.

How does ZServer performance compare with Apache pcgi Zope? > Medus sounds like it's pretty high performance. > Medusa screams. There are no solid benchmarks, but from extensive use of both servers in a Zope environment, Medusa is noticibly faster, perhaps by 200%, than Apache when publishing Zope objects. This comparison probably doesn't hold for other uses of both servers, and Apache has one gazillion little knobs and features you can use. > > I'm 100% with you there.

For example, if you had ZServer running and it's FTP listening on port 8021, the you would just (C-x C-f) '/username(a)my.machine.com#8021/' and you'll get a Dired of the top level of the Zope tree. Quite handy. -Michel > Thanks, > > Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice > Current Location: N. Rio Grande Bioregion, Southwestern USA > > >

Correct way to load DTML Document from source file?
by Piers Lauder 23 Apr '99

23 Apr '99

I'd like to load a DTML Document from source, and so far I've come up with the following (the HTMLFile...raw is the only way I've found to get the absolute path to a file from a Product given the last part) file = HTMLFile(file, globals()).raw try: fd = open(file) data = fd.read() fd.close() except: data = '' self.manage_addDTMLDocument(id, title, data) My question - is there a better way? Secondly - I'd like to load up an "index_html" if the current Folder doesn't have one. "hasattr" will tell me if an attribute exists locally or in the containment hierarchy - how do I test whether an object has its own (non-aquired) attribute?

This is because, of course, Apache and other web servers aren't FTP servers, so there is no way for Zope to interact with them. ZServer is a general purpose tcp/ip server (the full blown system it's based on is called Medusa) which we have written HTTP and FTP extensions for (based on the stock Medusa protocol handlers). <opinion> ZServer and Emacs is the hands down best way to 'manually' edit things in Zope. The idea of 'WYSIWYG' editors is a good one, but as has been pointed out, often they make lots of assumptions about the filenames, they're picky and flakey about acutally publishing, and they just want to do things their way. This often results in 'WYSINNWYAWAYCFI' (What you see is nowhere near what you actually wanted and you can't fix it). Emacs supports the concept of 'WYSIWYM', What you see is what you *mean* (A powerful concept brought to us by the TeX people). You can allways use your favorite WYSIWYG tool to generate the HTML, and then cut and paste it into a really killer tool like Emacs. </opinion> -Michel > > TIA > > Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice > Current Location: N.
