Hello Todd, Wednesday, June 06, 2001, 2:15:34 AM, you wrote: ST> I noticed this software from a post over at Hardhats in reference to ST> printing, http://www.scansoft.com/ Is there a problem, with just scanning BTW - there is another issue about scaners amd Zope. We now are testing a patient image database (Zope application with images in file system and metadata in Postgresql) in a local network. It became obvious how great it would be to scan (or get images from other TWAIN sessions) directly into a Zope application. Google search returned that such an option is available in ColdFusion - http://www.cfdev.com/activescan/technical.cfm ============================ Activescan Technical Overview What is it? Activescan is a Cold Fusion Custom Tag that gives developers the ability to allow clients to scan images from any TWAIN compliant scanner directly to a web server. Clients can scan images, resize and crop them, and upload them to the server with one easy to use interface. How Does it Work? Activescan uses a combination of TWAIN, ActiveX, and Javascript technologies in a Cold Fusion Custom Tag to create the scanner interface. The images are converted into JPEG format, then sent to the server using an HTTP form post. ============================ Which Zope release is scheduled to include <dtml-getimage>? ;-) Best regards, Alexander N.

Problem with ZOracleDA
by Ellis, Neil (FNB) 06 Jun '01

06 Jun '01

While using ZORACLEDA (the prebuilt NT4 binary) I'm getting the following error for an insert statement, when I copy the insert statement to PL/SQL it works fine ?? Any ideas Error: (24374, 'ORA-24374: define not done before fetch or execute and fetch') The ZSQL looks something like this: insert into dropdown_meta_table (mt_id, table_name, labelColumn, valueColumn) values(<dtml-sqlvar mt_id type=string>, <dtml-sqlvar table_name type=string>, <dtml-sqlvar labelColumn type=string>, <dtml-sqlvar valueColumn type=string>)

How does Namespace Acquisition in DTML methods called from PythonScripts work?
by J Kinsley 06 Jun '01

06 Jun '01

I have a folder 'foo' in my top level Zope folder which contains folders called 'sql' and 'forms'. The 'sql' folder contains sql methods, and the 'forms' folder contains fragments of a multi-step form. In addition to the two folders, 'foo' contains 'forms_header' and 'forms_footer' DTML methods which are common to all form fragments. Finally there is a PythonScript called 'process'. In 'process' I want to manipulate the data collected from the forms, call the appropriate ZSQLmethods (which work) and then call the next form fragment. The problem I am encountering is when I do something like: return context.forms.fragment1() I get a KeyError for every document/method called from within fragment1. What do I need to pass to fragment1 in order to get acquisition to behave as it would if I called '/foo/forms/fragment1'? Hopefully I have explained this properly since I have been up all night working on this. TIA... Regards, Jarrod Kinsley

passing parameters to DTML Methods/Documents
by Chris Ryland 06 Jun '01

06 Jun '01

There's no official way to pass parameters from DTML code to other DTML Methods or Documents, is there? I guess one can always do a <dtml-var expr="REQUEST.set('param', 'value')">, and use <dtml-var param> in the callee, but that seems kludgey. -- Cheers!

Hi Chris, > ...that sort of thing should be in a Python Script, shame on you! ;-) Do you have any clue why it doesn't work in DTML? I mean, it's described in the Tutorial - or did I do a formal error? Thanks again, Philipp

RE: [Zope] problem with dtml-var displaying None for NULL from po stgres
by Harris Peter 06 Jun '01

06 Jun '01

Hi Best way is <dtml-var field null="">, then you get an empty string instead of "None". <dtml-if field><dtml-var field></dtml-if field> may in fact not work for integer fields. It will omit zeros as well as nulls, if I understand dtml-if correctly.

Getting rid of Vocabulary object
by Felipe E. Barousse Boue 06 Jun '01

06 Jun '01

Hello all: I just created a ZClass, nothing fancy: one property sheet and a couple of properties. This ZClass inherits ObjectManager and ZCatalog. Now, when a class instance is added programmatically inside a newly created folder (also programmatically), it creates a "vocabulary" object. How do I prevent my ZClass instance to create this "vocabulary". I have not been able to find that. I don't need the vocabulary since I will be iterating over the objects within the folder and I don't want the vocabulary to be counted in. This was solved temporarily with an dtml if id=vocabulary ..... skip the object ... method. The setup is Zope 2.3.2 with hotfix, RedHat 6.2, Python 1.5.2 Any comments are welcome. Thanks in advance.

??? IDIOT QUESTION QUOTA EXCEEDED ???
by Eric Roby 06 Jun '01

06 Jun '01

To any of you Zopemeisters willing to suffer through my idiot question..... I am beginning to think I have exceeded my "Idiot Question" quota for the year.... Ok, here it is in a nutshell.... I can create instances (TTW) of DTML Method, DTML Document, and even HTML Document (installed product version 0.2) then use either an FTP client or a WEBDav client to make changes and update. NOW, if I try to use any of the previous as a base class for a new ZClass, the instances created (TTW) from this new class CANNOT be managed via an FTP client or a WEBDav client. I have made many false starts over the past week trying to isolate this problem. I have ruled out roles and permissions, although I still might be hosed here. Out of desperation, I am contemplating modifying the HTML Document product to fit my needs. But I shouldn't have to do that because that is what ZClasses is all about. Or I thought so, anyway. Any directions/insights are appreciated. Thanks in advance... Eric

Personalization (was RE: [Zope-CMF] List of subject/metadata sets?)
by Bjorn Stabell 06 Jun '01

06 Jun '01

Ok, time to throw in my RMB 0.166 (US$ 0.02). SITE VOCABULARY In other CMS's, e.g., SiteServer, Spectra (Cold Fusion), and Vignette the main use of the subject/keywords is for user profiling and personalization; although they call it Vocbulary, Site Categories, and Category:Keywords respectively. I see the restriction of subject-keywords in CMF as the beginning of standard personalization in Zope... something we sorely lack. Vignette's category:keywords are only two-level, whereas the others are usually multi-level, i.e., a tree. Have a look at http://www.siteserver101.com/book/chapter7/pm16.asp and related pages for info on how SiteServer does it. Basically, you're right in that each site's keywords will be different, depending on its use (intranet, vertical of some sort, etc). An example of this is the DocumentLibrary product that has a legal hierarchical index. Over time we should collect example indexes to easy personalization for websites. USER PROFILING Obviously, we know quite a lot about the visitor before they do anything on the website; we know which languages they prefer (or we think we do from Accept-Language), we know what time they accessed the website, if they have accessed our website before (if we put a cookie on their browser), we know where they accessed from (not for sure, of course) etc. This is good, but it doesn't really give us any indication of what the interests of this visitor are, so we can't make our site a good shop keeper recommending things. We need to create a user profile. One way to do user profiling is to tag the visitor with the keywords of all the pages he or she views, probably also tracking how many times a visitor has seen pages with this or that keyword. This kind of data gathered from the visitors behavior is called implicit data. It is very useful, especially since the visitor doesn't have to log in for it to be effective (you can just use cookies to give the user a 'psudo user'). Later, when the visitor logs in, we can merge the profile of the "pseudo user" with the real user. Another way is to simply ask a logged in user to fill out a form selecting which information he or she is interested in. Data gathered through forms in this way is called explicit data. In any case, you end up with a list of keywords that the user is interested in, maybe even weighted (if it is implicitly collected). PERSONALIZATION RULES Now we need a set of rules, hopefully editable by a normal content manager, to control the personalization on miscellaneous pages. The fact that "business rules" were editiable by normal users, especially useful for shops that want to run many different types of promotions, was one of the major selling points of Broadvision. The personalization rules are basically different queries on the user profiles. Let's say we have a sports site with a (stripped down) site subject vocabulary like this: /sports/ /sports/basketball/ /sports/basketball/redbulls /sports/football/ /sports/football/manchesterunited /sports/golf Let's say a visitor has an implicitly gathered (through tracking browsing) user profile like this: KEYWORD "HITS" /sports/ 11 /sports/basketball/ 4 /sports/basketball/redbulls 4 /sports/football 6 /sports/football/manchesterunited 6 /sports/golf 1 We can have rule like this: Show [the sport the visitor likes the most] = which of /sports/* have the most hits = football (I'm from Europe) Based on this we can have an area on our site template dedicated to promoting products that fit the user profile, in this case it would probably show footballs and football collectibles etc. We could even go as far as show collectibles for the team we know he or she is interested in. IMPLEMENTATION IDEAS I'd like to see a new CMF tool, portal_pzn, that would store the personalization keyword hierarchy and the business rules. I think that in the beginning, we can just let personalization rules be small python expressions returning some results. We could also group rules into rule sets, a la SiteServer, to make them more manageable. Let's say the tool was like this: portal_pzn/ vocabulary/ /sports/ basketball/ redbulls football/ manchesterunited golf/ rules/ set1/ favorite_3_sports = "return user.behavior.top('/sports/*', 3)" discount = "if user.type == 'VIP': return 20" etc. And in our code we would write: <dtml-in "portal_pzn.set1.favorite_3_sports(user)" ><dtml-var "promotions[_['sequence-index']" ></dtml-in> Each user object is extended with two profile objects: behavior = implicit data; each keyword has an associated "hit" interests = explicit data; just a list of keywords the user has explicitly said he's interested in Just like with sessions, we could store personalization in the ZODB but it'll probably be too slow for many uses. We should use a storage that is fast both for writes and reads, which means it'll probably not be very persistent. We could have it synchronize regularly with a more persistent storage, e.g., ZODB. Interests are more like subscriptions, and like subscriptions, have their uses. This is still simple. I'm sure, e.g., Broadvision offers much more when it comes to personalization. These are just thoughts; I don' thave any plans to implement personalization yet. I'd be happy to help others, though :) Bye, -- Bjorn Stabell <bjorn(a)exoweb.net> Exoweb -----Original Message----- From: Jon Edwards [mailto:jon@pcgs.freeserve.co.uk] Posted At: Tuesday, June 05, 2001 23:17 Posted To: Zope CMF Conversation: [Zope-CMF] List of subject/metadata sets? Subject: RE: [Zope-CMF] List of subject/metadata sets? (Note to self : Remember to engage brain before typing!) Yes, you're right - and as Marc pointed out, you can have everything you need in one catalog. I guess where I'm coming from, is that the catalog is serving two purposes, and sometimes it gets confusing to a relative newbie like me - 1. For the end user it allows them to search the whole system, and is quite often used to "construct" the pages - topics and sub-topics - they are viewing. I'm assuming it will also be used in some way to construct composite-documents. With a large site, containing many sub-sections (or a large organisation with quasi-autonomous sub-organisations/departments) it needs a lot of planning to allow all the possible searches users are likely to want. 2. Behind the scenes it is interacting with workflow/workgroups to allow people to process documents from creation to publication. ...and I'm still trying to wrap my brains round how Composite Documents and Versioning will fit into it all. This is assuming you have a site with multiple editors/contributors working on many sections/subsections/pages in different workgroups. I guess at some scale the complexity reaches the point where you need to separate the two functions... and my needs are somewhere in that vicinity! :-) i.e. you have two portals/catalogs, one for the internal organisation to do its workflow, collaboration, discussions, document-sharing (perhaps on their intranet)... and one where the finished results are published, and the public can view, search, discuss. But you still want some two-way connection between the two. Is anyone else reaching similar levels of complexity? Maybe I should re-factor and "divide and conquer"!! Sorry if this makes no sense! I think I'm having a bad-brain day! Cheers, Jon -------------------------------------------------- > Going off at a tangent, does anyone ever get the feeling that you maybe need > two portal_catalogs?

Wouldn't that mean you end up with lots of objects being indexed in two places? seb _______________________________________________ Zope-CMF maillist - Zope-CMF(a)zope.org http://lists.zope.org/mailman/listinfo/zope-cmf See http://www.zope.org/Products/PTK/Tracker for bug reports and feature requests

RE: [Zope] Permissions etc...
by Farrell, Troy 05 Jun '01

05 Jun '01

Laurie, After your user has logged in, are you using something like this to iterate over the folders? <dtml-in expr="objectValues('Folder')" skip_unauthorized> <dtml-var id> </dtml-in> The skip_unauthorized tag _might_ be what you're looking for. Troy -----Original Message----- From: Laurie Nason [mailto:laurien@tiger.bcm.tmc.edu] Sent: Tuesday, June 05, 2001 5:32 PM To: Zope Subject: [Zope] Permissions etc... Ok guys here's the problem I have various labs who each have users - each lab should be able to see it's own data only which is organised as follows... Root |-->MyDB |-->acl_users (for the managers) |-->Groups |-->Group1 |-->acl_users (for each of the members of the lab) I have 2 roles created in the mydb folder (dbusers and dbmanagers) - each of the members of each of the labs is assigned into one of these two roles. All my dtml methods are stored in the mydb folder. The dbusers and dbmanagers have view permissions and access contents information for all these methods. I want the users to log in and then be able to look at the index_html in the mydb folder which then iterates through the groups that they are in and displays them. I thought that if I gave the role dbusers permission to view the index_html document they would have to log in and then the document would work as required. Only it doesn't.... Is this the best way to do this? Any other ideas...? Laurie Laurie Nason Dept. of Biochemistry - N420 Baylor College of Medicine Houston.
