[Zope-dev] DTML sqltest tag and python expr. Bug in Zope Book?
Hello everyone, I was recently working on a quite big ZSQL method (around 100 lines). I was using only and tags and a lot of "like '%...%'", so thought I could make things look much nicer using and . But I ran into a big hurdle: I quickly searched through the archive and found the thread "[Zope-dev] ZSQL using LIKE operator", and in particular: http://lists.zope.org/pipermail/zope-dev/2001-February/009339.html which is exactly what I would like to do. But unfortunately, does not seem to work. We get the following error: " The "..." shorthand for expr was used in a tag that doesn't support expr attributes., for tag http://www.zope.org/Members/michel/ZB/AppendixA.dtml Is there a patched sqltest.py that I don't know about or is this a bug in the book? Anyway, does anyone know of a good reason why the sqlvar tag supports python expr while sqltest does not? Some obscure security hole? Or is the functionality just missing? And in that case, is anyone up for a patch? It's not critical, but the following kind of defeats the purpose of sqlgroup: title like title like The following would be much nicer: Note: in this particular case, I could preprocess the variables and add the surrounding wildcards in the call to the ZSQL method. But that would restrict the way this method can be called (URL traversal is definitively a cool feature to impress newbies ;) ), and that's not the point here anyway: we would just like python expressions in sqltest tags.

[Zope-dev] SmartSections 0.1.0 released
Hello everyone, Okay, all good things are three, so here is the last announcement. I also put SmartSections up on the server. Even though it is a big construction place, I thought you might want to look at it. Smart Section allows the End User which cannot write HTML code to design sites online. This is in particular in CMS solutions very useful., but it's really hard to describe what it is. It is simpler to just install and use it. Currently, the SmartSections behave very similar to iuveno's Kontentor iPages, but this time it is written in Python with as little overhead as possible and it is blazing fast as far as we can tell. IMPORTANT: SmartSections requires OrderedFolder!

[Zope-dev] SmartWizard released
Hello everyone, after a long night with a nice thunderstorm here in Nuremberg, I got the SmartWizard (first version) finished. Oh, you want to know what SmartWizard is? SmartWizard is a framework to generate Wizards for all sort of applications. The wizards are designed for the End User, so I tried to put some of the common Wizard features in it. ... if this is getting confusing at any point of time, just jump to the bottom and try it ;-) ... The wizard framework uses a very simple, almost totally in DTML implemented API. All of the required DTML Methods are generated and even pre-filled, so that you can view the wizard as soon as you got your first page written. Wizard Pages are the actual screens you are going to see. They also have always an action associated with them, so you can do some result analysis before going on to the next page. In order to make it even easier, I have also built a small Template Engine, with which you can register new Page templates, in case you have some Pages, which occur over and over again. Currently I have implemented four Page templates: o Wizard Form Page - This type of pages contains Entry Forms which are implemented using the great Formulator. o Wizard Section Page - This type of page displays a SmartSection as its main content. Later I want to use it to manipulate the Wizard right from the view. o Wizard Products Page - This page checks whether a list of required Products is already installed on the current Zope location. This is in particular useful for Installer Wizards, like the Proiektor Installer. o Wizard Tree Page - This page's purpose is to display an object tree and let's you choose an object from the list. You can choose in the Properties, which meta-types are being shown and what the start/default object is. I would love for people (I mean you guys) to come up with ideas for some new Page Templates!

[Zope-dev] (no subject)
Hello everyone! OrderedFolder (which is used by SmartWizard) is mainly a little patch to the _setObject and _delObject method of the ObjectManager to support 'ordering' in ObjectManager-derived objects. It is a really tiny adjustment, so I hope DC will put it in the core somewhen, since it won't effect performance. But in this release I added some support classes (or mix-in --> I just don't like the word), which allow you additionally to choose the meta-types that are shown in the Add list and I put the _is_transparent attribute into the Properties, so that you can activate and deactivate transparency (this required TranparentFolders of course). In the next release I am probably going to rename the Product to ConfigurableFolder, since the current title is too confusing.

I did not follow the entire discussion, but I think if there are the right tools like mk-zprod (discussed on the other thread on zope-dev) with a nice front-end, then we can make the learning curve less steep and encourage people to develop "real" products in Python. ;-) In fact, in a couple of minutes I will release the first version of SmartWizard, which will allow to write nice front-ends like that.

Well, the current wizard version (which I hope I will be able to release in a couple more hours) already has some Page Templates that do some of the common tasks. I think we could easily map this to the management interface. And I like the idea a lot. So often I am simple copying a DTML File just to change a name or so.

I look forward to boxed retail versions of Zope in the marketplace, whether from DC or someone else. But, I think it would be nice if those redistributions (of Zope itself) also came with source code, even if the distribution included proprietary Zope Products (with no source). I guess I'm trying to draw a line between proprietary add-ons to Zope, and proprietary changes *to* Zope. This would prevent Company X's proprietary Zope Product from only working with Company X's proprietary Zope distribution.

However GPL'd software is better guaranteed to *remain* Free than BSD-style licenses. If Zope had a GPL-like license that allowed both proprietary and GPL'd Zope Products (which subclass Zope base classes), I would be ecstatic (as opposed to 'merely' happy). I have some code I haven't released (and in a couple of cases, haven't finished) because I can't currently release them as GPL.

Re: [Zope-dev] Hey Chris, question for you
I think it has changed for FieldIndexes. You can now make the distinction
between "doesnt have that attribute" and "attribute is one of [None, '', [],
()]" within a Field Index. You do this in an almost natural way, the major
exception being that you need to wrap a blank string ('') in a sequence in
the query (e.g. title=['']) due to hysterical behavior.
I'm not sure about Text Indexes.

I have been able to (thus far) pull this off without compromises, which was my hope in the beginning. I guess the question here is given the query: spam != 'eggs' Should objects be returned that do not have an attribute "spam" at all. For the behavior to be intuitive, I would say yes, but that is just my opinion. I also though of an optimization that could eventually be included if this behavior is adopted. for example, take the following query expression: title == 'foo' and spam != 'eggs' As implemented, my query engine does the following: 1. Find items where title matches 'foo' (exact behavior depends on index type) 2. Find items where spam matches 'eggs' 3. Take the difference of all items in the index spam and the result of #2 4. Return the intersection of #3 and #1 To be "intuitive" (I use that term loosely) I think it should be: 1. Find items where title matches 'foo' 2. Find items where spam matches 'eggs' 3. Take the difference of all items in the catalog and the result of #2 4. Return the intersection of #3 and #1 Which can be optimized as: 1. Find items where title matches 'foo' 2. Find items where spam matches 'eggs' 3. Return the difference #1 and #2 If an "or" is used in place of the "and", then the optimization doesn't apply though. One other thing: I noticed (with a colleague) that passing a list of values to a FieldIndex and a TextIndex results in nearly opposite behavior. The fieldIndex does a union on the results of querying against each item in the list whereas TextIndex does an intersection. This seemed highly inconsistent to me, another thread perhaps... -- | Casey Duncan | Kaivo, Inc. | [EMAIL PROTECTED] `--> ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] ZPL and GPL
I'd like to add a quick clarification, then I'll reply more later. Frederico brought up a good point that indicated I wasn't clear. It is a *desire* of ours to be GPL-compatible. Not a requirement, as it can be awfully tricky, complicated, and time-consuming to get there. But we've told people that we're intending to give it a shot. --Paul Federico Di Gregorio wrote: > hi, > > i wanted to draw myself from this thread before annoying the whole list, > so i'll take paul mail as an excuse to write some final comments. > > On 27 Jun 2001 09:06:16 -0400, Paul Everitt wrote: > >>1) I wanted to specifically address something in Michael's post here. >>We fully expect people to profit from Zope, even if that means for-fee, >>intact redistributions.

Re: [Zope-dev] ZPL and GPL
With great trepidation, I add a post to this thread. As Barry has mentioned, this has all been discussed a LOT. I'll try to summarize and clarify a few points: 1) I wanted to specifically address something in Michael's post here. We fully expect people to profit from Zope, even if that means for-fee, intact redistributions. They simply have to provide credit. Others may have a different philosophy, but that's ours. This is similar in some regards to Perl's and Apache, I believe. 2) We specifically expect to produce a packaged version of Zope. It's clear that it's the only way to appeal to the mainstream market. We hope others do the same. 3) Regarding other posts, our license is nearly identical to Apache's license, close enough legally to say it is the same. Therefore, to say Zope isn't free enough is to say Apache isn't free enough. Anybody that says that loses a fair amount of credibility, at least with me. Apache is an example of a crossover success (open and commercial) that I think provides a fantastic role model. 4) Any changes in the license are likely to be more in the direction of an Apache-style license. No approach pleases everyone, unfortunately. We do the best we can. --Paul Michael R. Bernstein wrote: > On 26 Jun 2001 10:29:39 +1000, Anthony Baxter wrote: > >Michael "R."

I do not know about any spell checker either. You could write your own little spell checker quickly in a couple of hours. No problem (would be nice to have :-) ). Just use the DBAdapter/Method principle, where an Adapter links a dictionary (words.txt in Linux for example) and keeps it in memory for performance. You can then write a "Spell Checker" Method or another similar object that connects to this Dictionary object and does the spelling. I do not know much about a possible User Interface, but I guess you have enough examples yourself (i.e: Hotmail).
