However, I think it causes a problem with code like this: `` if a == '': doSomething() '' You could use ``code`` instead, though. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

DTML?

DTML should be easier than, say, creating a Form in Lotus Notes or writing a component in Mason. That requries, IMHO: 1. Clear definition of when it should be used. 2. A clean, concise syntax (like Python, DTML is more like Perl right now ;-) 3. Good documentation (much easier to do if 1 and 2 are met...) I also think having Python Methods ship with Zope would really help... There are niggles (like the rediculous id problem) which you can live with, but doing anything other than the really mundane in DTML means extreme hair loss right now, which is not good. I wonder how many other people would agree with me: nevermind ZEO, or the PTK, ZPatterns or any new fancy functionality. Can we at least have a decent template language that doesn't confuse the hell out of newbies and oldbies alike... cheers, Chris (Who just spent 1/2 hour figuring out how to do a multi-language site in Zope, and now after 6hrs of trying has given up doing a recursive tree copy to get the old site into the new structure with a DTML method or two and is resorting to ugly hacky external methods because Python Methods arent' around/stable) PS: Zope: yes it makes the hard things very easy, but it makes the easy things very hard, so it all balances out nicely... ;-)

serving object under different name
by Ingo Assenmacher 11 Jul '00

11 Jul '00

Hi. Scene: I have an downloadable object with id/title. When the user clicks on a link, say: <a href="<dtml-var id>"><dtml-var title></a> a requester pops up and asks the user where to store the file with the provided id. Lets say I want to serve the file under the title, not by id, how can this be done? (The requesters pops up and uses the title instead of the id as 'save-as' name.) (I store long, self explaining titles, but short not quite self explaining ids). Thanks for any help, Ingo.

The MessageDialog is cool, but a little sparse, has anyone tried overriding it with their own or fiddling with it? Im looking at including standard header and footer in it and not gotten very far. Thanks. -- Andy McKay, Developer, ActiveState http://www.ActiveState.com Programming for the People

Error Value: managemanage_editForm
by kwan 11 Jul '00

11 Jul '00

hi, I am using Zope 2.1.6 and Squishdot 0.4.1 Squishdot works greate and works the way as I want. However, I cannot edit the permission setting for a squishdot site. Whenever I try to change something I got AttributeError and the Error value is 'managemanage_editForm' So I tried to change the permission for individal roles, they works except the acquire permission setting part. Here I got the same error again. These are the error code I got form the page,  so, I look inside the setRoles function, it seems, 'self.data' contain the name 'managemanage_editForm' which cause the error, am I right here? I also look through the __init__() for squishdot, I couldn't see how it pass the 'data' passes to Permisson object when it first instance. Where should I look for to fix this 'managemanage_editForm' problems? Kwan

Heap Corruption Problem
by Dieter Maurer 11 Jul '00

11 Jul '00

Apparently, we have a serious heap corruption problem. The problem manifests itself in different ways: The Python process * receives signal 9 (SIGKILL) by Solaris 2.7 * receives signal 11 (SIGSEGV) * enters an infinite loop (and blocks the complete process) In all cases, the analysis detected that the fatal event occured in a memory management function, not always the same, however. The problem occurs about 1 to 2 times per day on a lightly loaded site (still under construction and test). Environment: Zope 2.1.6 binary release for Sparc-Solaris 2.6 Solaris 2.7 ZOracleDA 2.1.0 with Oracle 8.1.6 no other C level extensions I will keep you informed. Dieter

ZStylesheet multiple browser question
by Neil Burnett 11 Jul '00

11 Jul '00

I am new to ZStyleSheet. How do I create a rule which is different for, say, IE and Netscape? E.g. If I want a color to be red in IE and blue everywhere else (just an example :-) I can't do it in the same rule as attribute ids have to be unique, but they are also the name of the selector attribute. Is it right to create two rules (myclass_ie and myclass_everythingelse) or is there a better way? Thanks in advance Neil

Re: [Zope] trailing whitespace optimization
by Paul Abrams 11 Jul '00

11 Jul '00

Fellas, I got it to work :) I used the rstrip method from the string module to trim trailing whitespace from the end of each line whenever a document template gets saved. I tested it with DTML Documents and Methods, which both worked fine. It doesn't affect properties, so if you need to render trailing whitespace for some reason you could store that as a property. The mods are listed below. If you use it, let me know what you think and I'll write it up. Cheers, -Paul ------------------------------------- Trim Trailing Whitespace Optomization ------------------------------------- There were two changes to one file. \lib\DocumentTemplate\DT_String.py -from string import split, strip +from string import split, strip, rstrip ... def munge(self,source_string=None,mapping=None,**vars): """\ Change the text or default values for a document template.
