Simple REQUEST question
by Suneel Iyer 04 Apr '00

04 Apr '00

Hello all, I have the following simple code fragment: dtml-call "REQUEST.set('test',UserExists)"> <br /> The value of test is <dtml-var test> <br /> Where 'UserExists' is a boolean value set using <dtml-let>. I want to be sure that 'UserExists' is being copied into 'test', but <dtml-var test> does not yield the value of 'UserExists' (in fact, it yields nothing at all). What am I doing wrong? Also, I have some doubt about the scope of the REQUEST variable. For instance, if in the next line of the code fragment a call is made to another dtml method called "myMethod", does the REQUEST variable 'test' go out of scope in "myMethod"?

multiple visits to dtml-method page
by Daniel.Weber＠SEMATECH.Org 04 Apr '00

04 Apr '00

I have a dtml-method page that displays a table of values and allows the viewer to delete on of them (using an sql method on the next page). All works as expected, but I noticed an odd thing: when I used the back button on the browser the table of values was not updated, but showed the old values. This is bad, because people will think their delete did not work. How do I force a page update? I checked the IE5 options to make sure it was checking the date stamp on every visit, so I don't think it's a cache issue, though I don't know enough about browsing to say it isn't. Shouldn't forms be re-submitted on the back button? I'm sort of confused how this is all handled....

Problems with FTP port 8021
by Ken Kinder 04 Apr '00

04 Apr '00

I've been trying to use an FTP client to access Zope with little luck. As luck would have it, I'm behind an IP Masquerading box at home. The FTP module on Linux for IP forwarding works on port 21. This seems to be hard coded. Unfortunately, the firewall box is an old eSoft box that has an old version of Debian and Linux. It is also a headless box and if I try to install a new version of Linux, and it doesn't work, I'm screwed. This removes the possibility of recompiling the FTP module to work on port 8021. Is there a way I can use FTP port 8021 or an alternate protocol that works with IP forwarding? -- Ken Kinder 303.381.7631

Re: [Zope] Where does Object.createInObjectManager() find the object manager?

From: John Morton <jwm(a)plain.co.nz> > Anything that's inside the first <dtml-with...> should be operating in > the context of that newly creates object, so if the second > <dtml-with...> is place inside the first, that object should be created > inside the first one. I think the problem is that createInObjectManager is using the PARENTS array to find its ObjectManager, and the <dtml-with Object> statement doesn't touch that array. Thanks Bruce

URL traversal
by Andy Dustman 04 Apr '00

04 Apr '00

I'd like to be able to do something similar to the URL traversal that ZSQL methods do, but more something like this: http://localhost/blah/a/b/c/spam would invoke blah.spam(args=['a','b','c']), i.e. args is a variable-sized list of each path item between the object and the method in sequence order. 1) Is there a way to do this short of writing a Product? 2) Having already figured out the answer to #1 was probably "no", I have tried to write a Product that does the job. It used a helper class, similar to OFS.Folder.Traverse. My main problem (which I probably have to punt on) is that I'm trying to use __getattr__ hooks instead of __getitem__ hooks; I may need to switch to doing the latter to get things to work. The test Product (in theory) is essentially a Folder with the above semantics, because I needed something I could stick DTML Methods and other things into. This might be useful in general, as well. 3) Is this even a reasonable thing to try to do? I have an existing CGI script that uses the PATH_INFO like this (mostly; it just takes everything past a certain point as arguments). -- andy dustman | programmer/analyst | comstar.net, inc. telephone: 770.485.6025 / 706.549.7689 | icq: 32922760 | pgp: 0xc72f3f1d "Therefore, sweet knights, if you may doubt your strength or courage, come no further, for death awaits you all, with nasty, big, pointy teeth!"

Where does Object.createInObjectManager() find the object manager?
by bruce＠linuxvc.com 04 Apr '00

04 Apr '00

Hi, I am creating a Z class object using: <dtml-with "Object.createInObjectManager(id, REQUEST)"> I then try to create a sub-object _in_ that object with: <dtml-with "SubObject.createInObjectManager(id, REQUEST)"> The outer object is derived from ObjectManager. But both objects are created in the same folder rather than one being created in the other. Please tell me the right magic words. Thanks Bruce Perens

date-time manipulation
by mindlace 04 Apr '00

04 Apr '00

Zopistas, I have a date-time property called "created" in a dtml document. What I need to do is something like this: <dtml-if "(ZopeTime() - created) == 14days"> <p>Time's up! </dtml-if> How do I do this? Thanks, Ethan Fremen -- http://mindlace.net __________________ mindlace(a)imeme.net I don't want The Truth but I wouldn't mind a Big Analogy.

web folders - advice requested...
by Kevin Meinert 04 Apr '00

04 Apr '00

============================================================== I had no responses to this before, here is my question again: ============================================================== I want to implement a "web folders" style interface. For examples see: www.yahoo.com, www.netscape.com, http://directory.google.com/ I think http://directory.google.com/ is the best example, but anyway... I'd like to be able to edit the entries with a web browser, and be able to attach files to the tree - like PDF docs, and jpg/gif/png pictures. I'm guessing I could do it with MySQL... what does everyone think? Is there a Zope plugin that already does this. Does someone have some code laying around you could send me? Im basically looking for a good place to focus my efforts on, for now. Thanks! email me at KevinMeinert(a)bigfoot.com Kevin
