My experience with the Python development process is very good. New versions contain few problems which are rapidly eliminated. I will switch to Python 2.1 (now using Zope with Python 2.0) immediately when it becomes available (has nice features, I fought for since a long time (nested namespaces)). You will only be affected for Zope 2.4. I think, it will take several month, before it is final. Dieter

Zope support through the community: sorting
by Dieter Maurer 14 Apr '01

14 Apr '01

Zopistas, there is currently a heaty and controversial debate at http://dev.zope.org/Wikis/DevSite/Proposals/ExtendedDTMLSorting It is concerned with Oleg's great "Sorting Patch" that provides (almost) general, easy to use sorting facilities all over Zope's framework (DTML, Python Scripts, External Methods, ZPT, ....). There seems to be danger that this great support through a community member will have a fate similar to Tino's "in" patch: that the incorporation into the Zope core is far too long delayed because important DC people fear "feature bloat". If you are interested in sorting along the lines * case sensitive/insensitive * ascending/descending * locale aware * multi-column you should go to the above site and voice your opinion. As a general note: It seems to me that DC is far too reluctant to accept contributions to Zope from community members: * patches fixing bugs * patches implementing missing but useful features In my view * bug fixing patches should always be accepted unless the patch is not easily understandable. * feature patches should be accepted, if it makes Zope more consistent (as the upcoming "urlparam_expr" patch) or easier to use (as Oleg's sorting patch or Tino's in patch). Great reluctance towards these contributions risks Zope to lose community support. I can tell from experience the frustration caused by DC ignoring contributions. I invested considerable time to file several important ZCatalog bug reports with patches into the collector for Zope 2.1.6, just to see them ignored in all versions of Zope 2.2. Only for Zope 2.3.1, the issues have been addressed. I still advice people to file bug reports and patches into the Collector, but personnaly I already start to think whether it is worth the effort.... Dieter

dtml-in and namespaces
by Frank Tegtmeyer 14 Apr '01

Hi, I am mentally blocked now in getting something simple (I assume) to work. I want to check if all required fields in a form are filled - simply the presence of data is to be checked for now. My form processing is included in a <dtml-let> statement that defines the form variables and the descriptive names. Also the required fields are defined here. I want to check the required fields within a <dtml-in> statement. There I cannot access the fieldnames directly because my test would never fail: <dtml-let fields="{'m_email':'Email-Adresse', 'm_vorname':'Vorname', ... 'm_plz':'Postleitzahl' }" required="['m_email','m_vorname','m_nachname']" > <dtml-if expr="REQUEST.REQUEST_METHOD=='POST'"> <dtml-call "REQUEST.set('finished','true')"> <dtml-in required> Checking: <dtml-var sequence-item><br> <dtml-unless ????????????????> <dtml-call "REQUEST.set('finished','false')"> Missing: <dtml-var sequence-item><br> </dtml-unless> </dtml-in> <dtml-if "REQUEST.get('finished')=='true'"> ... </dtml-let> What has to be used in <dtml-unless>? Is there a better/simpler way to check the presence of required data? Form processing is such a basic requirement - ther must be hundreds out there that can answer my question :) Many thanks in advance! Regards, Frank

Zope + sql
by Herring, William O. 14 Apr '01

14 Apr '01

I hope someone has an example or suggestion. Using Znolk, I SELECT from a table and the list is viewed. However, I would like to choose certain records (mark them from the viewed list) and then change a variable of only the marked records to a single new value. The new and old variable values are finite, they could come from a pull down list. So the idea would be to show the list from SELECT, but have an pull-down menu of new values at the top of the page that should be replaced for the variable to edit. The user would choose the new value from the pull-down and then go down the page and mark each record for which that value would be UPDATEed in the table Once this is done the values would be passed back to sql and UPDATE used to replace the old values. I'm not quite sure how to do this either. Do you have a loop, where inside the loop the UPDATE is goes through each marked record, or do you loop inside the UPDATE tablename set variable=newvalue where ----loop here with or's------ Any suggestions or similar examples would be appreciated.

Help with DTML-var tag and Passing Variables
by Rob Senk 14 Apr '01

14 Apr '01

This works great as a link in a dtml method. I pass the variable "name" from the page in which this link is on and I get the user's address just fine <a href="<dtml-var q_address url>?Names.First_Name=<dtml-var name>">Get User's Address</a> What I really want to do is not have a link and just call all the data on one page eliminating the need for hyperlink. I would have thought this would work: <dtml-var "q_address(Names.First_Name=<dtml-var name)> It does not. Just shows up as txt on the page. If someone can help out I would appreciate it. I have searched the archives extensively and tried the various methods. Rob

Hi, I create a class whth two dtml method: edit, edit_done. This class has one Properity "Title" edit contain: ------------------------------------------- <form action="edit_done"> Title:<input name=inputTitle value=<dtml-var Title>><p> <input type=submit> ------------------------------------------- and edit_done contain: ------------------------------------------- <dtml-call "manage_changeProperties(Title=inputTitle)"> ------------------------------------------- but the edit_done dtml method can't modify the properity of the object of that class.

ZPT - how to get started with Macro, I get "version None" error
by Brad Clements 14 Apr '01

14 Apr '01

On Zope 2.3.1 without ParsedXML on Linux RH 7.0 I installed TAL and PageTemplates per instruction. I'm trying to use SimpleWelcome and the master macro. I created a folder named "test" In there I created two page templates, one called Welcome, with the SimpleWelcome text (modified) and the other template is called "master" with the sample master macro. I changed SimpleWelcome to be something like this: <html xmlns:tal="http://xml.zope.org/namespaces/tal" xmlns:metal="http://xml.zope.org/namespaces/metal" metal:use-macro="here/master"> <body> <div metal:fill-slot="main"> <p>Welcome to the machine</p> </div> </body> </html> (also tried "container/master") In both cases I get:  I also tried making Master just a DTML method.. No change. Does "master" have to be a ParsedXML document? I just need a little boost to get started, does anyone have this working on their Zope?

REQUIRING Python 2.1??
by anser 14 Apr '01

14 Apr '01

[ First of all, I wish people (including Digicoolers) would title their messages descriptively, not just say "Important notice" or whatever. I'm sure many of us consider our words important :) ] Second, I am MYSTIFIED (there's no better word) that DC is in such a rush to REQUIRE the use of Python 2.1 for Zope 2.4, when we're still waiting for Py 2.1 final to even come out. Why put all your eggs in that basket, and why force the community to choose between changing to a bleeding-edge Python or retiring to a frozen Zope rev? Does DC not realize that Python has OTHER applications besides Zope? and that for a given community site, changing Pythons might have unexpected side effects in systems whose developers are less gung-ho about rushing to 2.1 than DC is? I thought I'd set my mind at ease by reading the wiki Brian referred to -- which is called "SupportPython21" although it should apparently have been named "RequirePython21" -- but all I could glean from their justifications was [1] it'll make i18n easier (wow, that's huge), [2] there's some other things with strings and such that "may" be useful, and [3] of course there's a raft of other potentially disruptive differences, but hey, at least we found a way to make i18n easier! I can't quite help wondering whether someone at DC has maybe gotten so "into" the development of Py 2.1 that they just can't wait to use its new stuff, whether it's objectively what's best for Zope or not. The prudent thing to do would have been to add features as needed using 1.5.2-compatible code, or at best to offer a "new18n" branch that requires 2.1, which people who are THAT desperate for i18n could choose to follow if they wanted. Then, say 6-12 months after 2.1 is gold, you could unify and require it for 3.0. Instead, for the sake of being able to let the Python developers stick a Zope logo on the 2.1 release, we are risking a boatload of trouble. On the basis of prior performance I do not expect this objection to make any difference in what DC does, but I needed to express it anyway. That gives me a thought - anyone for "Rope"? :)
