how to keep stuff out of undo
by Roman Milner 30 Aug '00

30 Aug '00

Hi. We have a product (an mp3 jukebox) that uses the ZODB to store a large data structure of all the albums and track names. Many people are allowed to add/remove albums from the database. The problem is, when they do this the entire data structure is backed up for undo. So, by the end of each day, our ZODB has grown so large we are out of disk space. Is is possible make something presistent but keep it from being backed up when it is changed? Thanks, ^Roman

In other words, by not specifing anything for the field indexes, you are actually specifying that for a match, they need to be empty. To get around this, I put another method between the form for entering what you wish to search for, and the method that actually searches the form. This method looks at the field indexes, and if nothing has been specified, it doesn't pass them on to the method that does the actual search. An alternative to this, is to use names for the field indexes that aren't in the catalog index, and then at the start of the search method, check those names, and if they have a value associated with them, add to REQUEST what the names in the index are with the appropriate values. There may be a better way, I'm still pretty new to Zope and DTML sort of stuff. Peter Armstrong

Re: [Zope] getting parent document
by Anders Holmbech Nielsen 30 Aug '00

Thanks for your answer. This would do too, but Stephan Richter gave me a nice way to do it. A dtml-method with the following: <dtml-raw> Because of acquisition this will result in the "document" being included in its whole. His suggestions: 1. html: contains the HTML code viewMethod: called like: viewMethod?file=html <dtml-var "_[file]"> 2. The best by far. Write your own little Zope object in Python that has only an id and a body. Then you can say: URL/html/viewMethods Inside viewMethods: <dtml-var body> 3. Well, I found solution 3 reading the DTML Method source code pretty quick. inside viewMethod: <dtml-var raw> -- That returns the unprocessed body of the object and due to the acquisition behavior of DTML methods it looks one object up, which is html. so URL/html/viewMethod works >Anders Holmbech Nielsen writes: > > I have a dtml-method called test which I want to use like: > > > > someurl/document/test > > > > and in the dtml-method I want to include the document in its whole. > > > > I have tried something with the URL like: > > > > <dtml-var <dtml-var URL1>> this offcourse dont work... but this neither... >Try: > > <dtml-var "PARENTS[0](_.None,_)"> > >"PARENTS[0]" gives you the parent, in your case "someurl/document". >Calling this object renders it. >If you call it without parameters, you cut the namespace chain. >If you pass "_.None,_", you pass the namespace explicitly. >(This usually is done by DTML behind the scenes, but >inside "...", you must do it yourself). > > >Dieter -- Regards ------------------------------------------------- Anders Holmbech Nielsen | Tlf: (+45) 70 22 56 00 Software Engineer | Fax: (+45) 70 22 57 00 Integrator Uniware A/S | http:/www.integrator.dk

Re: [Zope] How to get PARENTS[-1] from within a Python Product

Thanks! It turns out the expression is self.REQUEST.PARENTS[-1].absolute_url() I'll see if I can put this into a useful tip. -- Ira Hochman go2ira(a)onebox.com - email (617) 598-1014 x5511 - voicemail/fax ---- Dieter Maurer <dieter(a)handshake.de> wrote: > Ira Hochman writes: > > How does one retrieve the equivalent of PARENTS[-1] from within > a Python > > Product in Zope? > ZPublisher places "REQUEST" at the top of the acquisition chain. > "PARENTS" is an attribute of "REQUEST". > > Therefore, you should be able to simple use "self.PARENTS[-1]". > > If it does not, try "self.REQUEST.PARENTS[-1]". > > > > Dieter > __________________________________________________ FREE voicemail, email, and fax...all in one place.

Nested dtml???
by Tim Hicks 30 Aug '00

30 Aug '00

I am trying to work my way up through folders, checking whether each folder has a property named 'site_root_folder'. Logically (in *my* head anyway), what I have written below is what I want to do, but I'm not sure that I'm really writing this the write way. I vaguely remember reading that I can't nest dtml-if tags within dtml-in tags. I'd really appreciate any help on this tim <dtml-let level=0> <dtml-in level> <dtml-if "PARENTS[level].hasProperty('site_root_folder')"> <dtml-var "PARENTS[level].absolute_url()"> <dtml-else level="level+1"> </dtml-in> </dtml-let> Tim: tim.hicks(a)iname.com

In your example, however, you give it an integer ("level"). It will not be happy with this. You may try: <dtml-in PARENTS> <dtml-let PARENT="_.getitem('sequence-item')"> <dtml-if "PARENT.hasProperty....> .... Dieter

The code is partially there, but incomplete and commented out. If you do not mind other extensions as well, I could provide a TreeTag patch for several extensions, including the icon customization.

FSSession problems...
by Curtis Maloney 29 Aug '00

29 Aug '00

Greetings, I'm using FSSession to store login details about visitors to our site. It is important that users only be able to see their own data (of course). Today, however, I find out that some mistakes have been happening. People are finding themselves logged in when they haven't yet, and others finding they're logged in as someone else. This is, obivously, a problem. I cannot see how this could be happening, since the Session ID is stored in a cookie, which should be unique to the client. I am using: Zope 2.1.6 on Solaris 2.7 FSSession 0.4.0 Have a better one, Curtis.

Question relating to a zope product 'Tracker': email problems
by Julian Harris 29 Aug '00

29 Aug '00

Hi all I'm having fun with Tracker (a Zope product) -- certainly it's looking to be a very useful tool for us. But I'm having a problem submitting issues. I get this error when trying to submit an issue: Error Type: SMTPSenderRefused Error Value: (555, 'syntax error (#5.5.4)', 'julian(a)edreams.com') We sniffed the header and it seems that the mail line below is the culprit: mail FROM: <julian(a)edreams.com> (what you can't see is that there's a rogue space after <julian(a)edreams.com> which causes the syntax error on our server) Tracker uses the smtp libraries in Zope. Anyone encountered this kind of problem before? Any suggestions about how to fix this? Either in code, or what I have to do to configure it differently...? thanks so much in advance! PS if I wanted to make a change to the source on my machine, do I have to compile it? I see these PYC files everywhere but I thought Python was an interpreted language? How would I make a change if I found that I had to tweak the code a little? -- Phone: +34-93-508-8550 or 667-914-832 if urgent
