Re: PossitionIndex (was: Re: [Zope-dev] ZCatalog phrase indexingrevisited)
Once you're satisfied with the implementation, would you be willing submit the module to the collector? Do you think you (or someone else for that matter) could have a look at [1] the method that returns the position in the document - positionInDoc() - to how that could be made to run much faster? Maybe it is how it used... It is too slow to be very useful when indexing large amounts of data. Anyway, I suck at making Python fast (or using it the right way, which ever I've fallen pray for this time ;-), and any hints would be greatly appretiated. I've been indexing and searching a lot this weekend, and bar that problem with the indexing-speed it seems ok and I have no issues submitting it to the Collector. Doing something similar (in fact what I needed was citations of word usage) I took a two step approach, with the idea that most of the actual returning of results would have to be done on a much smaller subset of documents than if you'd have to index all documents with word indexes and positions. I use a normal textindex for querying. Then if a document is returned by the query I start processing the documents. This requires parsing the query in a slightly different way (throw out the NOTs). The two step approach has the advantage that you can postpone processing actual documents until you return the results for the specific documents. Using your positionInDoc will require a _lot_ of processing (why does it use string.split btw and not Splitter?; why split on and not on string.whitespace?). I have used string.find for finding word positions, which is probably faster than looping a list of words. BTW, I'd rather use Splitter, but word positions appeared not to be reliable (bug, or something I didn't understand; anyhow, string.find works for me and is fast) def splitit(txt, word): postions = [] start = 0 while 1: res = string.find(txt, word, start) if res is -1: break else: start = res+1 postions.append(res) return postions sidenotePerhaps using re would perhaps also be an option, but allowing regular expressions will complicate searching a lot, so I use globbing lexicon for expanding and then do the matching on the expanded items (if necessary - not if using [wordpart]*)/sidenote Advantages of using this approach: - it's faster. - it splits up the query processing part in different subparts which also contributes to speeding things up. - it's also more flexible, as you can divide searching and parsing over different webrequests, and even make them dependend on the number of results. For example: why return text fragments from all documents if your users will not be able to see all the results anyway. Or why return all fragments containing word combinations from one single document while returning a few occurrences from different documents is more useful for your users. Note that this will mainly affect returning text fragments, which may or may not be useful. There's also a couple of disadvantages (as I see them , but there may be more): - it only works with exact word positions and not numbers in a text. The within two words approach may be remedied by using string.split on substrings however if really needed. Depending on you purposes an even rougher approach is by taking some default length for words (this is a bit faster). These are not very elegant solutions, though. - because of an approach that is not so coupled with (Z)Catalog, integration strategies are less obvious (at least for me) - the positionIndex might be used for further processing as is, in my approach this is less obvious. another 2 cents Rik ___ 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] Zope Projects in NL/Europe?
(Writing from the Netherlands) Just wondering: are there any Zope projects are available in the Netherlands/Benelux/Europe? We did one last year but they seem hard to find. Are there commercial projects available or is Zope mostly used on internal projects? Is there any demand for Zope expertise around here? From the (spontaneous) requests I have had over the last year about Zope expertise, I can assure you that there is plenty of demand for Zope expertise. The problem is mainly that it is harder to find (commercial) expertise than to have projects available. Zope not (yet) being such a widespread Web developing alternative, needs are less visible. We are using Zope in our institution and there is too much work for me to handle, but I have had a hard time finding developers who can help me out. I'm sure this applies to more institutions and companies in the Netherlands (and Belgium for that matter). And, btw, not to be nitpicking, but how would people know you have Zope expertise? Is it in your company profile, are you on the Zope service provider page, have you offered your services somewhere visible. The second point is of course that you could also prove Zope to be a viable alternative over other web developing tasks, by just doing projects in Zope. Or are all you customers asking for applications in specific technologies rather than solutions with the highest quality/for the best price/in the shortest time possible? Reason I'm asking is that I'd love to continue working with Zope, but it's hard to justify in a company focused on Microsoft and Oracle, especially if there is no money to be made. I can learn Perl on company time and Linux is our internet server OS of choice, but JSP/Java and .NET (the latter is not that bad, uses SOAP/XML-RPC) is next if we don't find a use for our Zope expertise.

Re: [Zope-dev] case insensitive sorts
Andy McKay wrote: Minor nit and patch: I've found that really for me what users want to see is a case insensitive sort of objects, not the current python case sensitive sort. So that the order of objects from dtml-in and tree is a, A, b, B as apposed to A, B, a, b. Anyway Ive patched dtml-in and dtml-tree to do this sort on a ignore_case tag. Is this useful to anyone else? And Ive thought of patching my Zope so this is the default behaviour what does anyone else think. The next thing to patch is ZCatalog... The way I approached this was to have a ZPatterns attribute provider, or a method, that provides a modified version of the value I want to sort on. For example, I have a load of documents and folders with titles like Big Folder brown document "Berries for Cooking" list I wanted to present these sorted by non-case-sensitive first letter or number. So, I made a method "title_for_sorting" that stripped off any punctuation at the start, and returned the first 20 characters in all lower case. In this case, as it was a ZPatterns application, the method was presented as an attribute of the object using some skin-script. I used this attribute as a field-index in my SiteIndex ZCatalog. The reason I mention this is that sometimes case-insensitivity is not enough for sensible sorting. In this case, I had to strip out punctuation too. Hm, reading this... just a loose comment. In light of the awkward search interface of ZCatalogs, would it be a good idea to make a search interface for ZCatalog ZPatterns based? This would add the possibility to make it configurable wrt case sensitivity, and to do nice things with ANDing and ORing different kinds of indexes.

Just the following section is defying my attempts to make it run. What it does is to update a field in the database (to allow employees to quickly update their hours in the hours tracking thing I'm creating) it's complex since all the employees hours will be listed on one page and will be instantly updatable (with a select box that allows the choice of +/- (name is modifydtml-var hoursID and value is either + hours already input or - hours already input) and a text field for entering hours to add or subtract (name is mod_hoursdtml-var hoursID)).

If anyone can help out I'd be very grateful. This seems to be more of a DTML problem than an Access problem. It is hard to follow anyway... A few questions: have you tried using something like changing the form names to using the name.item:records syntax. something like input type="checkbox" name="modify.dtml-var hoursID:records" value="+" input type="checkbox" name="modify.dtml-var hoursID:records" value="-" input type="hidden" name="modify.inputhrs:records" value="hours already input" and a text field for entering hours to add or input type= "text" name="modify.mod_hours:records" value="dtml-var hoursID" this will give your dtml method a dictionary like structure called modify you can loop over.

Re: [Zope] zope basics
Using Zope, I have managed to put together a nice site for friends to create
folders, pages and upload images, etc. But there are some fundamentals that
are eluding me.
I am able to 'register' a new user through a form to create a new acl_user.
But I cannot figure out how to let them login again using that name/password
and be an AUTHENTICATED_USER with that acl_user name--other than Anonymous
User. I tried to look at AUTHENTICATION_PATH, but my browser wants to
download it--an empty file.
[rh]If you have an object to which an Anonymous user has no access, an
authentication dialog automatically pops up. If you want a real login page,
just give it restricted access, but you could any page in a restricted area
for that. Using basic authentication this is a bit clumsy. There are more
sophisticated authentication mechanisms available for Zope.
I can manage objects using dtml pretty well: create, delete, edit. If I can
figure out how to authenticate a user, I would like to be able to add a
property to new objects as they are created: (createdby:AUTHENTICATED_USER)
so that I can control which objects get a checkbox (for delete) and an edit
link for a particular user. InOtherWords, if a user creates a object, I want
that same person to be able to go back and delete or edit that object.
Anyone else can see it, but they won't be able to delete or edit the object.
[rh]Objects normally get an Owner property (under the ownder tab). In this
case you could use something like (untested)
!--#if "AUTHENTICATED_USER.has_role('Owner',this())"--
You own this Folder.
!--#/if--
this is taken from http://www.zope.org/Documentation/How-To/DetectRoles
This confuses me: manage_addProperty takes (id, value, type and optionally
REQUEST) as args. What is the id? Is it the ID of the object that you want
to add a property to? Or is it the ID of the new property? The Zope Quick
Reference doesn't say, but I think it is the property's ID.
[rh]It's the id of the property. Remember you call the method on an object
(or rather in the context of an object) with an id, so passing the
manage_addProperty the object's id once again would be superfluous.
I am trying to learn from looking at the Zope interface work. After
submitting the add property form, the page url looks like this:
appRoot/objectname/manage_addProperty. I see that the objectname is behind
manage_addProperty, I know the value, id and type are passed in the REQUEST.
How can I take advantage of this following a line like:
dtml-call expr="manage_addImage(id=title, file=file, title=title)"
...to add a property to that image?
several options (just in dtml, all not tested):
dtml-call expr="your_image.manage_addProperty(id=yourid,
value=yourvalue, type=yourtype)"
dtml-with your_image
dtml-call expr="manage_addProperty(id=yourid, value=yourvalue,
type=yourtype)"
/dtml-with
Note that if the REQUEST has the right values (from a form) you can
alternatively also just pass it the REQUEST , the manage_addProperty method
will know how to take the variables from the REQUEST.
I found some useful tidbits at a howto page on Zope site somewhere. But it
was pretty sparse and just whetted my appetite. I am coming from NT/IIS ASP
world. So I am struggling.
[rh] But you have much to win ;-)
Can anyone point me to a richer source of samples that will help me get up
this hill?
There are a faq and a ZSnippets on zdp.zope.org which may provide some more
examples. Also look at the many howtos. The documentation section of the
zope site should be making them more easily accessible in some time.

Another friend is the Zope Quick Reference (http://zdp.zope.org/projects/zqr). 3. I need to make a site that allows users to register ( i.e. to generate user folder with some standard documents in them). Anyone have hints regarding this? (or in fact a whole application I can use?) Look at GenericUserFolder or LoginManager. As an addition: look at the PTK: it does many of these things for you already and at least it may be a source of information (http://www.zope.org/Products/PTK). The only issue is that it's, um, quite dynamic at the moment if you want to develop code with the PTK as a base. Some might say a moving target. But if you look for inspiration it will be fine on all accounts. hth Rik- ___ 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] Zope and Windows DB's = NOT! ?
hi, is anybody successfully using a Windows DB such as MS SQL server 7 with Zope? it seems that the ODBC adaptor is ancient and very error prone so can i conclude that Zope and DB integration under windows is not an option? In general, the ODBC adapter may be old, but it works well and generally without problems in my experience. In the Zope Book it's even claimed that it's commercially supported! The point is just that it's single threaded. If you need to use SQL Server 7 there also is a mxODBC adapter, that claimed to be multithreaded. I don't know about its status right now.

Re: [Zope] Problems with Zope 2.2.2 and MS SQL Server
I'm having some troubles connecting Zope 2.2.2 to Microsoft SQL Server. I downloaded and installed the product ZODBCDA, and I was able to connect to the SQL Server. I was able to define the SQL methods, and when I test them, everything is successful. The problem is that when I use for example the dtml-in tag to iterate over the results, and display them in a page, I am always prompted for a password, but I can enter whatever password I want, I can never get through. Does anybody has an idea of what I'm doing wrong and how I can solve it?? Did you use a Search interface on you SQL Methods (it is a standard product in your Zope installation)? Did it give the same problems?

Re: [Zope] Zope and Windows DB's = NOT! ?
hello andy, hello all others who answered my post, first of all thank you for letting me know the positive experiences you have had with the ODBC adaptor and your various installations. i'm relieved that Zope and window's DB's do work together -- and this prompted some new tests on my part. their still seems to be a minor issue with an error message the first time we query a MS SQL 6.5 DB. a few reloads later everything seems to work fine. kind of weird. there used to be a similar issue in a previous version, that had to do with single threads and transactions not being committed. But that was patched long ago. That's probably not it and I know it's kind of cryptic, just thought I'd bring it up, just in case. guess the only major thing left is the single thread issue. yes, that's bad.

I can't begin a dtml-let because I would need to close dtml-if before

What is the "accepted" way of passing a value into a different scope? Do I
have do a REQUEST.set or is there a tidier way?

Also I think I read somewhere that you can use the object.subobject or
object.property syntax but I never got that to work, what's the catch?
dtml-var expr="object.subobject"
note that this is a Python expression and the code between quotes has
Python behaviour.
One last thing, I sent a couple of mails to the list about problems I had
with manage_delObjects. I still haven't got it to work. Since the best way
to learn Zope is by example, I wonder if anyone could direct me to a sample
piece of code where a container of some sort deletes one of its children

Re: [Zope] querying status in zsql
I have a processing script that takes emails and puts them into a table. I bring up a table for confirmation and then submit the whole thing by a iterative item:records zsql method. My problem is that the table requires a unique primary key and quite regularly there duplicates. So ofcourse it falls over with the expected error. I have tried in the zsql method encapsulating the sql with a dtml-if "checkforexistantrecord" and then at the bottom of the zsql loop I commit so make sure the second time around, the data is checked. This does not seem to work. So what im left with wondering is, if I can query in the zsql method: if error, then exit or go somewhere else Is this possible? yes, this is possible. If I understand your question at least. BTW This is untested, but I have used something similar before mailid is the input field/variable for your method dtml-in emailitems dtml-in checkexistant_error(mailid=mailid) (if this is another zsql method) dtml-if sequence-start skip or do something else dtml-else upload your email. You may want to call another Zsql method for this /dtml-if /dtml-in dtml-in sorry to be very vague. The conundrum is the fact that the zsql method it an item loop in its own, so i cannot seem to use an if statement because it doesnt iterate by the normal dtml-in route Any advice? hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope-dev] ZPatterns: Non-ZODB storage and Racks
[rh]I've been following this thread. This may be a bit of a newbie question, but it's been bugging me for a while. I see how I can store propertysheets in Racks using ZClasses and Skinscripts, but the propertysheet term suggests that there should always be an object that the properties are attached to. Is that an actual ZODB object or is it the Specialist object that can 'create' virtual objects on the fly? It's determined by the radio button setting on the Storage tab. If you neglected to set it to "loaded by accessing attribute " and fill in the blank, then your objects have been stored in the ZODB, as well as in the RDBMS. Roche wrote: Thanks. I set "loaded by accessing attribute" to the attribute "id". Storing items in the RDBMS works fine. But when I try to retrieve them with getPersistentItemIDs() nothing is returned? I have a skinsript method getCustomer: WITH getCustomerSQL(CUSTOMER_ID=self.id) COMPUTE id=CUSTOMER_ID, name=NAME and getCustomerSQL is a SQL method. [rh] If I read this right, this suggests that an object stored in a SQL database and 'masquerades' as a Zope object? Or does an object always have to exist in the ZODB (with it's own id that corresponds to the id in the RDB or knows how to retrieve it). In other words, does the ZPatterns framework need an 'anchor' in the ZODB to connect it's properties to, or can you create pure virtual objects, that retrieve all of their properties from a specialist, including the ID. If the last is the case, could someone give an example how to implement it. A very simple one would suffice I suppose (hope).

Re: [Zope] university portal
I'm another Zope newbie with a few questions. My appologies if this message is being sent to the wrong mailing list. this is the list I'm a final year student doing a project to create a course/personal management system for my university. I understand there's quite a lot of similar work going on in this field already. I aim to create a database to store student information in (using mySQL or Zope?) or both. This really depends on what you want and how many users you expect . Some user management products (Zopish for components) are flexible enough to accommodate both. ZPatterns and a Zpattern based products (like LoginManager?) allow you to switch from one implementation to another halfway. Experimenting with ZPatterns is not a newby thing though... ;-) which the user (the lecturer) can add content to (details of grades, etc) via a web browser and use for bulk manipulation of data... sending email amongst other things.

Going through Zope's 'Elvis' tutorial this seems possible. this is the realm Zope is suited for par excellence [Q] Is it possible to present a user with various web forms to input information (say, a news article with headline content) that once submitted will be displayed on the page in a suitable format?

Re: [Zope] Where is the code?
I have played with Zope and got everything working. It is however not clear to me how the code (DTML and so on) is merged into Zope and where it is kept. Would gurus out there point this to me? thanks. DTML and Zope (code) objects are kept in the object database. It is in zopehome/var/data.fs on your filesystem. If you create a new object, Zope creates a new instance of a class that is in Zope. They are defined in Products. The products are visible in your zope site at http://your.site/Control_Panel/Products Zope products/classes may be defined in Python modules. In that case the modules live in the zopehome/lib/python/Products directory. They may also be defined in ZClasses, which are defined completely through the web. They are not visible on the filesystem, only in Zope itself. I don't know whether that was your question, but DTML is interpreted at runtime by the Zope system.

"Months without rebooting"? That is certainly not something to brag about. With three of my installations of Zope on Linux I have the machines at 194, 204 and 55 days of uptime (and the 55 was because of a bad powerstrip, the other others have been up since I brought them up). While NT can and does stay up for long periods of time, it still is a very poor server choice as anything you install leads to a reboot.

Re: [Zope] Content Management System
This query started out in a separate thread about permissions, but it's sufficiently important to me to pose again here. I've been struggling to make the CMS abilities of zope user-friendly enough for 'joe average' end-users. Really it's designed for a 'power' content manager who delegates, secures, and generally has taken the time to study all the Content Management docs, etc. However, most of my clients don't have those kinds of requirements and aren't that technologically savvy, so I end up coding ultra-simplified interfaces for them on a per-project basis. I know you can restrict permissions on just about every available method, and I am aware of the current skinnable zope project, which may improve the situation drastically. But I'm interested to know, how many of you offer the Zope TTW interface to clients as a content management system, and how many just use it as a development interface? I'm beginning to wonder if content management and system administration should be split out into separate subsystems. Or if a CMS Tool Kit should be developed. (workflows, syndication, etc...). But I'm still far from being a zope power user myself, and have yet to appreciate the range of its potential. What do you people think? The PTK might offer you some help in this respect. Zope as a CMS _is_ possible, but IMO you'll have to wrap the parts of the management interface that you want to expose to your users and hide the rest. This will effectively limit you as to what you will let your users add to Zope, but in a CMS situation, this will probably be the case anyway. The management interface as is won't mean much to most of them, but custom forms can also call the manage methods. It's probably a good idea to use something like the HTML Widgets product that was recently announced here, or the HiperDom thing. For most of the user management parts you will probably need someone with affinity for web developing, though as long as you keep the tasks constrained, some simple instructions will probably suffice. I have been developing something similar in what should be a course framework (a product that I don't seem to be able able to finish) that is geared toward an educational situation. It's predecessor has been in use at a university for some time and it seems to suffice as least as good as commercial packages. hth Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Need preferred 'import' format for ReportLab Image module
to reply to Andy? In my own reportlab distribution I changed; import Image to from PIL import Image Well, it sounds right and if it works then it probably is ;-) It probably depends exactly where you install PIL, though, which I haven't done yet :-S The Photo product and the ExtImage products do more or less the same - this seems to become the standard way.

Re: [Zope] expr=id 'index_html issue
Okay, this is my second question for the day. Hopefully it won't be as
easy as
the first -- otherwise, I'll have to stick to practicing law.
I'm looking for a way to list the DTML Methods in a folder -- except the
index_html method. So far, I've had to do it by using this:
dtml-in expr="objectValues('DTML Method')" sort="title"
dtml-if expr="title 'The Title'"
td align="center"a href="dtml-absolute_url;"dtml-var
title_or_id/a/td
/dtml-if
/dtml-in
This works but it is a maintenance headache. A more elegant (and
reuseable)
solution would be to use the id, which is always 'index_html' for the
to-be-excluded method. However...
dtml-in expr="objectValues('DTML Method')" sort="title"
dtml-if expr="id 'index_html'"
td align="center"a href="dtml-absolute_url;"dtml-var
title_or_id/a/td
/dtml-if
/dtml-in
.. doesn't work.
Does anyone know why?
Short answer because id is not always a string you have to call it
differently
try untested but this is a faq:
dtml-in expr="objectValues('DTML Method')" sort="title"
dtml-if expr="_[id] 'index_html'"
td align="center"a href="dtml-absolute_url;"dtml-var
title_or_id/a/td

Re: [Zope] IIS port problem
snip description http://srnt/ChatClub/index_html note that most probably the reference will look something like http://srnt/cgi-bin/Zope.pcgi/ChatClub/index_html That is, you'll loose the port, but you rape your url. If you want a shorter url, you most probably have to do other (isapi like) things to IIS I don't want any reference to the server port 8080. I have read several help documents on IIS and PCGI AND THEY ALL SAY DIFFERENT THINGS. One document said to copy the Zope.pcgi to the IIS cgi-bin folder and another said to copy it to the IIS scripts folder. the main point is you need _one_ (not several) Zope.pcgi file that has the proper locations of all the things needed in it. It does not matter where you put it. In your zopehome/pcgi/util directory there is a pcgifile.py script that will help you check the pcgi info file (that is the very Zope.pcgi file I referred to). If this doesn't report any errors, your IIS-pcgi connection will probably work. One document showed the Zope.pcgi file path configuration completely different from mine. The document showed : PCGI_MODULE_PATH=X:\WebSite\lib\python\Main.py And mine showed PCGI_MODULE_PATH=F:\InetPub\wwwroot\cgi-bin\ZopeSite\lib\python\Zope this may be true, but it's a strange place for a Zope installation The document even had files I didn't have anywhere in my directory like pcgi.soc and some in completely different folders like: hm, IIRC the soc file is Unix only. Help document: PCGI_MODULE_PATH=X:\WebSite\pcgi\pcgi.pid My file: PCGI_MODULE_PATH=F:\InetPub\wwwroot\cgi-bin\ZopeSite\var\pcgi.pid I know there must be a a simple way to accomplish this. It can be simple, but it may turn into a nightmare if it doesn't work (you have been warned).

Re: [Zope-dev] mailing list 'noise'
I dont see this as a problem: You only create a new list when the traffic for that proposal gets too great for zope-dev. Threading is good enough before that point. Yes, but zope-dev has a relatively high traffic load... Why should you have to put up with all that 'noise' if you're only interested in posts for your comparatively small discussion? I read the 2-10 articles that I'm probably interested in, and miss the 95% which is almost always noise. The question is why you'd want to receive all this if you don't have to (as remarked above). ...because it is usually a mistake to categorize any discussion as small, to exclude it from the mainstream zope-dev. I started this thread with a request that developers use zope-dev in the way requested by the Fishbowl Process document - but (I assume) it has also been valuable to people thinking about a next-generation wiki. That would not have happened if discussion was partitioned into Wikis (Todays wikis - not VaporWikiNG) unless some WikiNgWiki person was (by coincidence) keeping up with the FishbowlWiki. Are you really advocating that? No, did I sound like I did? as long as you can follow it. But for prolonged and diverging discussions? Not quite IMO/Experience. Can you explain why? Because discussion change topics. Because most people only answer parts of the post. Because you throw away parts of the posts (I know you shouldn't but the mail client is not under your control). Because you loose overview and you can't step back and take a look at the whole thread.. Because no one ever summarizes the discussions. They could, but they won't. I have done these kind of summaries for several intricate Zope related discussions and when you start summarizing it gets very clear that for a larger discussion only parts of the issues involved ever get discussed. Or, to summarize my point, maillist discussion are hardly ever consolidated. It's like having a meeting without an agenda or a chairman who gets the thing going. In the case of a meething once in a while a good chairman/moderator takes back the discussion, summarizes and puts up the open points for further discussion. If you ever experience a meeting that needed someone to guide it, but didn't have one, then you probably know what I mean. Or for discussions that you fall into in the middle? Agreed - Todays Wikis are better than todays email list archives. Ha! ;-) And what if you want to follow discussions at different places, with different tools and you depend on a POP Server or differential access (POP/IMAP/Web) to a mailserver? Its true that the web model is increasingly becoming a lowest common denominator. Are your suggesting that a majority of Zope developers actually need that? Um, I couldn't tell with any certainty. In light of the adoption of Wikis, I suppose so yes. People seem to have been unsattisfied by the maillist and or other discussion tools. It's also remarkable that DC did not adopt Squishdot as a discussion forum, yes. And apart from this, a WikiNG would benefit a much larger community, of which I _am_ sure that it needs it. (Agreed, a VaporWikiNG that does both would be nice) Agreed that for now there are no tools that do such thing. That is also why it's worthwile to get WikiNG out of the vapor notwithstanding the myriad of discussion tools that have been around for many years already. As I understood it, the discussion is less about tools and more about modes of discussion. But we couldnt be having this discussion (in any mode) without tools. did I say that? *My* email and news tools support the mode of discussion that we are advocating *better* than *Todays* Wikis I think everyone agees about that, but at least some of the participants in this discussion also agree that most of the existing discussion tools for any mode of discussion are frustrating and insufficient at times. Moreover, apparently not everyone favours the same mode of discussion and this alone would be more than enough justification for a product that would cater different modes of discussion _at_the_same_time_.

Re: [Zope-dev] I feel your Wiki Pain ;-)
Do you feel that weblogs are bad models for debates? I think they're pretty good least-common-denominators. I would probably prefer the kind of annotation-based thing i described in my last message (and began to sketch in the WikiNG proposal) for collaborative generation of documents, but i can see the place for weblogs, just as i can see a place for network chats. With adequate integration of email (for notification and response), i see them as better than just email... I like the email list proposal of Martijn Faassen earlier on this list. I added some comments to the Wiki discussion page, where someone proposed using XML for Wikis: I agree with Peter that the proposal is practically shouting XML all over the place. In a Zopish way this would mean dividing up a Wiki page in different objects (say Topics or Paragraphs or whatever). So a Wiki page would become an XML document, consisting of Wiki node documents. The advantage is that this would allow for a presentation in the form of - one or several continuous pages as in the OFWikis (OF=Old Fashioned as opposed to NG). - a presentation with 'folded' nodes (like in a folding editor) - a threaded discussion a la S[qu|w]ishdot or the Discussable thingy - an XML document (for who would want it) The editing could be in the form of Martijn Faassens XML Widgets editor: put a node point in front of a 'discussable' node, promote that one to the top when the 'node point' is clicked on and allow for editing. An example below, in which the o stands for an editable (=clickable) node point (for wiki reasons I have not put blank lines between them. pre o this is the first editable node (user::time) this is a comment to it (user::time) and another comment to that (user::time) this another one (user::time) more comments o this the second one this one is not editable o this one is (user::time) a commennt to the last node /pre alternate view (in threaded discussion mode - probably know to all): (- is foldable; + is expandable) pre -This is the first editable node + this is a comment to it - this another one - and another one to that - this the second one this one is not editable +this one is /pre another 2 cents Rik ___ 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] is dtml-unless someIndirectVariable possible ?
I have a lot of REQUEST like this one to check, depending on what
documents are in the folder.
dtml-unless SOMEREQ
dtml-call "REQUEST.set('SOMEREQ','defaultvalue')"
/dtml-unless
RH: this should work. It works with me
so i gave all documents concerned 2 properties
myPropName,myPropValue
(in our example
myPropName : SOMEREQ
myPropValue : defaultvalue)
So i'm able to iterate the documents and check the properties and
set the REQUEST.
dtml-in "objectValues(['DTML Document'])"
dtml-if "_.hasattr(this(), 'myPropName') == 1"
dtml-call "REQUEST.set(myPropName,myPropValue)"
/dtml-if
/dtml-in
this works OK.
But, I can't find a way to generate the
dtml-unless SOMEREQ tag.
Passing the value of myPropName seems to fail (erreur while
parsing the syntax, or check the 'myPropName' instead of his
value).
I tried a lot of things and syntax around dtml-unless
myPropName, but it failed.
RH: Um, as you describe it, you mix up the name of the property and its
value (but that might be a matter of desciption). Try something like the
following
dtml-unless "myPropName==SOMEREQ"
dtml-call "REQUEST.set('myPropName', defaultvalue)"
/dtml-unless
note that 1) this will only work if there is a myPropName and a defaultvalue
variable in the namespace and 2) this won't change the value of the property

Hi there, I am working on a project and have been looking at the Zope Content Management System as part of the solution. However, I have a couple of questions. From what I have seen so far, the page generation is all done through the Zope Management Interface, and the content of the page is done through a textarea requiring the user to have knowledge of the zope system(DTML) and HTML. With type type of solution I am looking for however, I need page content to be generated be users that have little or no knowledge of HTML. What I am wondering is if it is possible to integrate the Zope content management system with Cold Fusion as I can allow users with no knowledge of HTML to use an interface designed with Cold Fusion to create page content. I do not wish to build a content management system from scratch with Cold Fusion. Any suggestions and/or comments would be very helpful. Um, intergration with Cold Fusion would be strange I think. WHat your question is, probably, is whether you can you wysiwyg HTML editors with Zope. Some minor inconveniences aside that mostly have to do with file extensions, the answer is yes. As Zope speaks ftp and WebDAV and a host of other protocols, you can easily prepare Zope content with tools like HomeSite and Dreamweaver (and many other tools).

the trick. This can get very confusing. Wouldn't know if that's the matter

Re: [Zope] Bug zClass subobjects?
(Second post) (I speak french, sorry for my english!) I created a ZClass, zRow. This class can contain other ZClass: zField_Text, zField_Date, etc. This let me define the columns contained in a zRow. I then defined a Class zTable, wich contains zRows. Question: - In my manage tabs, I needed to have a tab "Define columns". To achieve this, I inserted a ZRow Instance (with id "Definition") in my zTable product definition, and a method called "Define_Columns", containing: Perhaps it is a better idea to assign the Define_Columns in the Views of you zTable zclass definition (it is a separate tab in the management interface there). You can assign any tab name there to any method in you zclass. But I'm not sure I understand this correctly dtml-with Definition dtml-var manage_main /dtml-with And I defined a view "Define Columns" pointing to that method. When i click on the "Define Columns", I can see the manage screen of the instance "Definition", that's what I wanted. But when I try to add a zField to "Definition" instance, the zField instance is created at the zTable level, not IN "Definition" instance! All the classes are derived from on CatalogAware, ObjectManager. Are they by any chance nested ZClasses? If so, this is a known problem. If not, it is not entirely clear what you're doing. In general, if you create a ZClass instance to make it appear in the target you intend, it is important to do so through calling it through a manage_addProduct['yourclass'].yourclass_factory and _not_ directly through the yourclass_add method.

Re: [Zope] I think, it is a bug in acquisition
Maybe I have found a situation, where images are not working or rather
acquisition.
For example, you create 2 documents and one image
doc1 (DTML Document)
contents: "document 1 dtml-var doc2
doc2 (DTML Document)
contents: "document 2 dtml-var image
image (Image)
contents: image
When you put everything in one folder and try to render doc1, everything
works fine. You get your image at the end. But if you put doc1 in a folder
below like
doc2
image
subfolder
doc1
you get the appended error.
When you remove the image call from doc2
everything works again.
You're probably right about this, or my Zen has left me. I did some testing
and it will work allright if you move doc2 to the subfolder. i wonder if it
is an acquisition bug, though, as it seems to work with other objects in the
same setup. Could this be an Image bug?
I checked this with JPicture - the same. Beside,
today I posted another mail with "[Zope] __call__ error message - I gave
up". In this situation I thought my coding was wrong because I wanted to
list all documents with
dtml-in "objectItems('DTML Document')"
dtml-var sequence-item
/dtml-in
try (untested)
dtml-in "objectItems(['DTML Document'])"
dtml-var sequence-item
/dtml-in
the object items returns you a tuple with (id, object). Are you sure you
want that - it won't show on the html page
perhaps
dtml-in "objectIds(['DTML Document'])"
dtml-var sequence-item
/dtml-in
or
dtml-in "objectValues(['DTML Document'])"
dtml-var sequence-item
/dtml-in
will bring you more luck

Re: [Zope] Fun with Trees

After RTFMing and flailing at DTML all night, I'm about stumped.
No pun intended.
I'm trying to use dtml-tree to create a selective menu of objects based
on whether or not the object has an "add_to_menu" property. I've pretty
much figured out that I need a wrapper around objectValues that will
filter out the objects that don't have the "add_to_menu" property.
This wrapper would be called with dtml-tree's "branches" attribute.
I'm trying to do this wrapper in a DTML method and I've gotten all the
way to where I have to return a list of "actual objects", so says the
DTML Quick Reference.
Is there someone who could 'splain to me how to build a list of objects
in DTMLese?
Here's what I have so far (obviously not working):
dtml-call "REQUEST.set('ret', '')"
dtml-in "objectValues()" sort=id
dtml-if "_.has_key('add_to_menu')"
dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'])"
/dtml-if
/dtml-in
dtml-return "_.string.split(ret)"

Try (yes, this is tested):
dtml-call "REQUEST.set('ret', '')"
dtml-in "objectValues()" sort=id
dtml-if "_.has_key('add_to_menu')"
dtml-call "ret.append(id)"
/dtml-if
/dtml-in
dtml-return ret
Two notes:
- the string approach is an unnecessary hack. I changed it to standard
Python list idiom
- if you append sequence-item it will include your whole method, which
presumably is not what you want in your tree. Use id.

Re: [Zope] queries and tiny tables and python methods... oh my!

Hi everyone,
(Please excuse the vague Wizard of Oz reference in the sub., but my brain
may be imploding. :-)
I'm trying to merge several type of Zope objects, and I'm getting lots of
little errors. I wonder if someone could suggest where my problem lies.
1. I'm querying our LDAP server to retrieve the records for a given person
in the directory. No problem there.
2. I'm parsing one of the entries in the LDAP directory to retrieve the
user's location. Python method code is simple.
3. I'm using a Tiny Table to look up a value for one of the parsed strings.
Easy.
The problem is hooking them all together. Passing the query to a
PythonMethod is throwing up the following error:
Error Type: TypeError
Error Value: argument l: expected read-only character buffer, instance found
The error means you're trying to split up a string, but the argument is
no string, but an instance (a Python Object). In many cases this is
caused by an omission of parenthesis, like so
called_object instead of called_object()
in which case the object is referenced instead of called and nothing is
returned (of course). I did not find the culprit in your description,
though.
snip
(Object: parseLocation)
(Info: ((['SB_B208'],), {}, None))
File string, line 2, in parseLocation
TypeError: (see above)
I do not quite get what part you want to parse. Is it 'SB_B208'?
accessing this in python is a bit strange due to the returned value. You
get to the 'SB_B208'part in the following way:
whateverreturnstheresult(someargument)[0][0][0], meaning (in this
case):
the first element (of the list) of the first element (of the first
tuple) of the returned tuple
parseLocation is a Python Method which takes 1 argument (a string) and
returns the first element of the list that's formed by splitting the string.
That first element is a two-letter code that's looked up in a Tiny Table
called buildingCodes which returns the full name of the building.
OK, it looks to my relatively inexperienced eyes that the Python Method
isn't getting an argument of the type is expects.
yep, see above
Here's the code for parseLocation ('l' is the argument):
x = string.split(l, '_')
return x[0]
I may be reading badly, but can you explain what the l is (or is
supposed to be)? Is it the tuple in the traceback?
(BTW, changing it to x = string.split(`l`, '_') eliminates the error, but
nothing is rendered.
qry_person is an ZLDAP filter method that takes one argument (uid). The
original dtml to display this mess looks like:
dtml-call "REQUEST.set('user_id', user_id)"
dtml-in "qry_person(uid = user_id)"br
dtml-in "buildingCodes(parseLocation(l))"
dtml-var buildingbr # 'building' comes from the Tiny Table
/dtml-in
/dtml-in
I'd appreciate it if anyone has any ideas about this. I'm probably making
the whole thing too complicated, but for reasons of code reuse, this seemed
like the most efficient approach.

Re: [Zope] ZCatalog counting?
A presumably simple question: Is there an easy way to count the number of occurences of a certain meta type in a Catalog? E.g: I want a dtml snippet that outputs: There are 123 DTML Documents in the Catalog. I've browsed the howto's, but didn't find anything like this. Can anybody offer me some assistance? To quote a mail by RD Murray from a gew days ago: How do I find the size of the results returned by the catalog? dtml-let results=Catalog() dtml-var "_.len(results)" -- the results' length -- /dtml-let Also at the zdp site: http://zdp.zope.org/projects/zsnippet/snippets/DTMLContent/CatalogResLength Rik ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] ZWiki/Structured Text formatting surprise
Hi,
Just noticed that (_.None,_, gets rendered as (.None,, in a structrued
text wiki. Not useful :/
Hm, in a structuredtextdtml Wiki (such as the Zope edu Wiki) this works. See
the SandBox there http://www.zope.org/Wikis/zope-edu/SandBox. So I can't
reproduce it now.
I've got around this by doing ('_'.None,_, but that's not really the
right idea.
Does anyone know of the proper way of escaping this?
Won't the !_.None help?

um, not to be nitpicking, but if you'd want to know the number of objects
with a certain meta-type in a folder, the following is a bit shorter and
saves you an iteration:

dtml-call "REQUEST.set('counter', _.len(objectValues(['DTML Document'])"
This folder (dtml-var title_or_id) has dtml-var counter

Re: [Zope] parsing strings in DTML
I'm working on what should be a simple problem.
I pulling an address out of an ldap query and the data is in the form of a
$-separated string. Example:
101 Main St.$Anytown$MN$12345
Please correct me if I'm wrong, but I could probably do dtml-call
"REQUEST.set('parsed_address', _.string.join(old_address, '$')" except for
the fact that getting "old_address" (the $-separated one) would require its
own dtml-var old_address statement. I can't nest dtmls so how to I
combine these?
I'm not sure I get you right.
try something like (untested):
dtml-call "REQUEST.set('parse_address', _string.split(old_address, '$')"
for parsing the string
Second question... Once I've got my string parsed into a list called
"parsed_string", what's the syntax for accessing certain elements of the
list?
By slicing:
dtml-call "parsed_string[0]"
gets you the first element parsed_string[1] the second etc
parsed_string[1:] is everything after the second ;-) element of the list
parsed_string[:5] is everything up to element 6
parsed_string[1:5] is everything from element 2 to element 6
parsed_string[-1] is the last element of the list.
If you want to know more, you should probably look at the Python docs, as
this is Python stuff.
P.S. Maybe I should do this in an external or python method, but I thought
it would be overkill for a single operation like this. Am I wrong?
No, I think you're right, but others may disagree.

Re: [Zope] Python install included with zopeBeta.exe?

It almost never does remove everything Deleting everything in Zope web site virual directory. Looks like I installed Python and then Zope installed Python again. ? I missed the part where you installed Python. But Zope does install it's own Python, to be able to run it right away, without having to fiddle with PYTHONPATH, name clashes and all. Did I miss this in the docs? (that Zope installs python in addition to installing Zope with the x86.exe?) Are there official installing docs then? Never seen 'em (there is something called installation tree at the zdp site, but I lost track of that). Seems like beta2 is working properly now (Quickstart and all). Good.

Re: [Zope] Writing to LocalFS
(thanks to Jonathon and Dieter... for the permissions problem. That
did the trick)
Again, after some searching, I am looking for the syntax to write a
file / append to a file in a Local File System.
This is certainly where my Python days seem to slow my down b/c I
would have just:
contents = open('/path/file.txt', "r")
to read and
contents = open('/path/file.txt', "a")
to append.
I am sure that I am missing some bit of Zope Zen here...
Please point me in the right direction...
Not sure if this was the question, but here's a relevant quote from the
python library reference
http://www.python.org/doc/current/lib/built-in-funcs.html#l2h-139
quote
Return a new file object (described earlier under Built-in Types). The first
two arguments are the same as for stdio's fopen(): filename is the file name
to be opened, mode indicates how the file is to be opened: 'r' for reading,
'w' for writing (truncating an existing file), and 'a' opens it for
appending (which on some Unix systems means that all writes append to the
end of the file, regardless of the current seek position).
Modes 'r+', 'w+' and 'a+' open the file for updating (note that 'w+'
truncates the file). Append 'b' to the mode to open the file in binary mode,
on systems that differentiate between binary and text files (else it is
ignored). If the file cannot be opened, IOError is raised.

Re: [Zope] Problem with adding items to ZClass instance
I don't think there's anything "special" about my ZClass. It's derived from Catalog Aware and ObjectManager. I believe I reproduced it without the Catalog Aware and got the same results. I'm using Andy Dustman's version of the MySQLDA and TinyTable v0.8.2. They both work just fine once I get the objects in the right place. Maybe the problem just happens to be with these two products, but I have no clue. You're welcome to fetch the product at ftp://ftp.logicetc.com/pub/Zope/IssueTracker.zexp if you want to give it a look. It's a one day throw-together port of the issue tracking system used by the PHP project with modifications for my own needs. OK, I downloaded it and I think I found your problem (not wure how to remediate this, though). If you look in the source of the management screen http://localhost/somefolder/IssueTrackerInstance/manage_main, the dropdown list for adding Product looks like this: FORM ACTION="http://localhost/somefolder/IssueTrackerInstance/" METHOD="GET" SELECT NAME=":method" ONCHANGE="location.href='http://localhost/testhier/blup/'+this.options[this.selectedIndex].value" OPTION value="manage_workspace" DISABLEDAvailable Objects OPTION value="manage_addProduct/OFSP/documentAdd"DTML Document OPTION value="manage_addProduct/OFSP/methodAdd"DTML Method OPTION value="manage_addProduct/MailHost/addMailHost_form"Mail Host OPTION value="manage_addTinyTableForm"TinyTable OPTION value="manage_addProduct/OFSP/manage_addUserFolder"User Folder OPTION value="manage_addZMySQLConnectionForm"Z MySQL Database Connection /SELECT INPUT TYPE="SUBMIT" VALUE=" Add " /FORM As you see, most of the items have a manage_addProducts/ as a start. Not so with TinyTables and MySQLConnection. They call the add_TinyTableForm and manage_addZMySQLConnection form. They do not switch the namespace to manage_addProduct (not in the form). Why this is a problem, I can't tell, but this _is_ the problem. I'm not quite sure about the solution. Probably it's best to make a custom manage_main form that does the right incantations for adding products and then map this to your Contents View in the ZCLass definition. As a side I'd like to remark that all products should comply with the same manage_addProduct interface, because the current situation leads to nasty problems.

Re: [Zope] Internationalization 2nd post
How are my fellow Zopers handling Internationalization, especially text. We have a site that is composed of several hunderd pages. We don't use classes but we have made heavy use of aquistion though. For example we have one back button that is aquired thoughout the site etc etc. Basically if the functionality (or code) is used in more than one place it has been but into a method and aquired. Any thoughts or hints? You could use a number of different 'language specific' folders and make your site acquire from them. There is a caveat, however, because you have to be careful to use acquisition in this way.

I have reinstalled zope and zodb, and copied the data.fs across. It was about two days old. All the changes that I had made were gone. Luckily I made a backup of my app yesterday by exporting it.

As for your error: I have had to throw away a corrupted (read: one that couldn't be opened) logfile before on NT. It made it possible to restart Zope again.

Re: [Zope] PropertyIds
I have a very simple documentclass in very simple structure in method that
should return the properties of the document:
dtml-call "REQUEST.set('tid', REQUEST.cookies['careermanid'])"
dtml-with RESULTS // RESULTS is a ZClass Object Manager
dtml-call "REQUEST.set('tmp', _.getitem(_['tid']))" // tmp is a
document with an id equal to the cookie
dtml-return "tmp.propertyIds"
this line should read:
dtml-var "tmp.propertyIds()"
Two things going wrong:
1. the dtml-return tag is for DTML Methods that should just return
something. You want dtml-var.
2. you call propertyIds in an expression (the line is shorthand for
dtml-var expr="tmp.propertyIds()" - in that case you have to call it
as a function.
/dtml-with
During the application i add properties to the document and want to display
them with the above method. The Property ids does not get shown though.
I've tried:
dtml-with tmp
dtml-var propertyIds
/dtml-with
this should get you a list, like ['title', 'prop1, ...]
and also:
dtml-in "tmp.propertyIds"
dtml-return sequence-item
/dtml-with
this doesn't work for reasons outlined above.

Re: [Zope] PropertyIds
Thanks Rik it works. I've noticed in some cases that one puts empty brackets at the end of certain zope object methods. Is that there for methods that can take parameters? [rh]Um, not quite, it has to do with the way of calling the object methods in question. DTML has two ways of calling: by name and through expressions. 1. The 'normal' Zope way of writing things is dtml-var objectValues. This is shorthand for dtml-var name="objectValues". 2. The other way is dtml-var "objectValues". This is shorthand for dtml-var expr="objectValues". Everything inside the expression is treated as a python expression. If you call it without the brackets, you're just referencing the method. If you try that in a DTML Method and look in the source of the diplayed document you'll see something like Python Method object at 13fcbf0. If you want to _call_ the method, you'll have to add the brackets (with or without arguments). Hope this is clear.

The items I'm adding aren't other ZClasses, but rather from python products. I haven't come up with an exhaustive list of which items cause the problem and which don't, but I know at least the TinyTable and ZMySQL DB Connection do, and the DTML Methods/Documents, MailHost and UserFolders don't. Everything is being added via the interface. I haven't tried adding them via DTML. I've never done that because I haven't had a use for it, so I'm not sure I know how. I setup a series of screen shots to demonstrate exactly what's happening. Take a look at http://www.logicetc.com/Test/zclass_problem if you're interested. I looked at it, and found it fishy. The strange thing is, I tried to reproduce it, but I can't. To be sure I added a tiny table plus to an instance not a straight tiny table and a ZODBC adapter, but I doubt whether this would make a difference. Anyway, they both work straight away. This is getting very strange indeed. It seems strange things are happening to your namespace. I can think of some things that may cause problems, but this is all speculation. This may be a bug, but then it's a special one. Anything special about your ZClass - what does it derive from (just objectmanager? anything else that might cause strange behaviour?). Is there a subobjects tab in it's definition? Are the products in there?

Re: [Zope] Problem with adding items to ZClass instance
I discovered something bizarre that happens in my 2.1.4 and 2.2b1 installations. Bizarre, yes, unusual, no. I have a ZClass based on ObjectManager. In an instance of the ZClass, I can "Add" most of the available objects (DTML Documents, DTML Methods, User Folder, MailHost to name a few). However, for at least two items (TinyTable and ZMySQL DB Connection), when I add them, they show up in the container folder, not in the ZClass instance. Then, if I check it to delete it, it gives a "does not exist" error. Upon refreshing the container folder, the item still shows, but then I *can* delete it. Equally interesting is that I can Copy the item from the container folder and successfully Paste it into the ZClass instance. However, since ZMySQL DB Connections don't support Copy/Paste, that won't work. What's going on? Is it a problem with my ZClass, the Product manage_add, or Zope? Or me? This is not so easy to answer. ZClasses do strange things to adding items. If your ZCLass definition (in the Product) is nested in another ZClass, then it is your ZClass. If the ZClass definition is defined in the top level of your product.
