<dtml-expr> second thoughts
by Kevin Dangoor 31 May '00

31 May '00

A couple days ago, I sent a message proposing that creating a <dtml-expr> tag could eliminate a lot of the confusion that new Zope users face. It seems that almost every new Zope user gets hung up on the difference between <dtml-var foo> and <dtml-var "foo">. It just now occurred to me that creating <dtml-expr "foo"> does not solve the problem, because there are still <dtml-if "foo"> and <dtml-in "foo">. While I am certainly in favor of keeping expressions in DTML, it looks like <dtml-expr> is not a good way to eliminate the confusion for new users. Perhaps the best thing is to just make sure that the introductory docs cover that topic very well. Kevin http://www.byproducts.com - Humor and Novelties

mailhost problem
by Mike Mikkelsen 31 May '00

31 May '00

Hello all, I have zope 2.1.6 and the following code returns an smtp error 553 (domain name required): <dtml-in select_Get_Account> (the select statement *is* returning the correct account) <dtml-sendmail mailhost="MailHost"> To: <dtml-var account> From: <do_not_reply@somebodycom> Subject: Mailing Back Password Your password is <dtml-var passwd>. Thank you for shopping at sombody! </dtml-sendmail> Your password has been mailed to <dtml-var account>. <dtml-else> blah blah blah </dtml-in> When checking the mail logs, the smtp server is getting no From or To information. If I use "mailfrom" in the dtml-sendmail tag, I get smtp error 503 (receipt required). Any ideas? -- Mike Mikkelsen mikk(a)microbsys.com Micro Business Systems http://microbsys.com Fresno Linux Users Group http://linux.fresno.ca.us It's all GNU to me!

HomeSite Question
by Luis Cortes 31 May '00

31 May '00

Hi, I'm trying HomeSite HTML Editor - which is really slick for somethings. I was wondering if there was some easy way to turn off the mangling of dtml tags when switching between design view and edit view??? Thanks ahead of time for your help, Luis.

Tweaking the management interface
by peter 31 May '00

31 May '00

I'm not a Python genious, but I do know some Python and a lot of HTML. I would like to experiment with changing the way the management interface is built up. The management interface of Zope is basically built up in two-column frames like this: ------------------ | | | | | | | 1 | 2 | | | | | | | | | | ------------------ Which is in HTML code: <frameset cols=175,*> <frame name=manage_menu src=http://url/manage_menu> <frame name=manage_main src=http://url/manage_main> </frameset> But I want something like this: ------------------ | | | | 1 | | | | 2 | |-----| | | | | | 3 | | ------------------ Which is in HTML code: <frameset cols=175,*> <frameset rows=150,*> <frame name=manage_menu src=http://url/manage_menu> <frame name=manage_extramenu src=http://url/manage_extramenu> <frame name=manage_main src=http://url/manage_main> </frameset> In frame 3 I want to load a DTML Method, DTML Document, Python module, .dtml file or whatever is possible to load there. So I can change this simply in zoperoot\lib\python\App\manage.dtml I save a file called extramenu.dtml in the same location as menu.dtml and main.dtml, zoperoot\lib\python\App\ and zoperoot\lib\python\Ofs respectivly. All I get is an 'Resource not found' error in frame 3. So, where should I save my extramenu.dtml and should at all call it extramenu.dtml or manage_extramenu.dtml? And do I have to change any Python code?

Re: [Zope] absolute_url and growing URLS????
by Dieter Maurer 31 May '00

31 May '00

Hello Andrew > I've got a strange problem I call "growing URLS" > > When I click on links that take me around a section on folders on zope, the urls just keep > piling on each other. This seems to be an effect of aquisition. In Zope, you can see at a place everything that is above it in the Zope tree. Example: If your page has URL: a/b/c and inside you page you use the *relative* URL "a", your *browser* will form the URL "a/b/c/a". In a normal file systems, this will give a "Not Found" error. In Zope however, you will get "a" but with the "URL" "a/b/c/a", because "c" has aquired "a". So you must be careful with relative URL's. Look at the URL* and BASE* Zope defined objects (--> DTML reference). They can help you to contruct (absolute) URLs. You may also use ".." to go to a parent. Dieter

RE: [Zope] Proposal for mail-in to Zope
by Chris McDonough 31 May '00

31 May '00

I'm interested in this, although I have a lot on my plate right now and can't help in development. I see objects in Zope being able to handle a call to one of their methods that passes off a chunk of email text and stuffs it in an attribute for later display or catalog. I think you should probably start by designing the interface to these kinds of objects and worry about exactly how you're going to call the methods that make up the interface later... > -----Original Message----- > From: Simon Coles [mailto:simon@nipltd.com] > Sent: Wednesday, May 31, 2000 11:54 AM > To: zope(a)zope.org > Subject: [Zope] Proposal for mail-in to Zope > > > Hi, > > We (NIP - in the form of Chris Withers, Stephen Harrison, and Simon > Coles) have put some thought into the question of how to get emails > into Zope, and have come up with a design which we thought we'd pass > by the list before we start doing something. > > The problem we are trying to solve is basically being to email > "something(a)myserver.me.com" and that email ends up in the Zope ZODB > processed in whatever way is appropriate. > > We aren't worried about sending email, that's done well at the > moment.

ZCatalog
by Tom Scheidt 31 May '00

31 May '00

Hi All, Im using: <dtml-call "Catalog.catalog_object( URL, DestinationURL() + '/' + id())"> to catalog stories that are created from a factory. In the catalog the name looks fine but the link adds and extra http://www.website.com so the slink ends up being http://www.website.com/http://www.website.com/story/story_html . Any ideas on how to remedy this? I've tried everything and searched everywhere. Thanks Tom Scheidt | www.falsemirror.com | tom(a)falsemirror.com ---------------------------------------------------------------------------- -----------

Bulk loading stuff into Zope
by David Hodgkinson 31 May '00

31 May '00

Warning: Zope newbie alert :-) The CEO at the place I'm gigging at the moment wants to be able to Cc: a portal with his email pontifications and then have commentary on his thoughts. Would someone be so kind as to give me some ideas as to where to start doing this with Zope? A slight variation on this is pre-loading a pile of stuff that's already on disk.
