Upload Photo objects in a localFS
by William GARCIA 13 May '02

13 May '02

I have a local file system named images. I would like to write-in photo objects. When I write an Image object with <dtml-with images> <dtml-call "manage_addProduct['OFSP'].manage_addImage(REQUEST['id_img'],file,'')"> </dtml-with> there is no problem, but when I try to write a Photo object with <dtml-with images> <dtml-call expr="manage_addProduct['Photo'].manage_addPhoto(id_img, '', file)"> </dtml-with> Zope generate the next error : Error Type: Bad Request Error Value: Cannot add objects of type 'Photo' to local directories.

Thanks in advance for the help or the ideas you can give to me. William.

The elvis tutorial Here's a sample Python Script to set a cookie: request = container.REQUEST RESPONSE = request.RESPONSE tag=repr(DateTime().timeTime()) RESPONSE.setCookie('zopeimp',tag,path='/') return You do not need a function to read a cookie. Cookies are in the request. I recommend that you add this line to your standard_html_footer: <dtml-var REQUEST> You'll see everything that's in the request. Great for debugging! Admittedly, Zope Book is still somewhat incomplete and the example you tested may be wrong. I did not test the Elvis example but I'll try to give you general advice: Do not rely too much on Zope Book as "the complete, perfect source of documentation". The best resources that complement Zope Book are: - Archives of this mailing list - http://zopelabs.com - your own testing (try-fail-try-fail-try-success method) Write your own small test scripts. Record the results of these test scripts in a good knowledge management system (I use Hierarchical Notebook, available from SourceForge for both Linux and Windows). Build your own know-how. -- Milos Prudek

TextIndexNG is a pluggable index for the ZCatalog that enhances the full text indexing capabilities of Zope by providing the following features: * support for document converters (HTML, PDF, WinWord, PowerPoint, Postscript). Custom converters can be easily added * stemmer support for 12 languages * optional support for right truncation * similarity search (soundex, metaphone support) (for english) * NEAR search * phrase search * pluggable query parsers (two parsers included) * stop words support * new test tab for interactive testing * 2-3 times faster than Zopes TextIndex (more to come ;-) ) * compatible with ASCII, ISO-8859-1 Requirements: * Zope 2.5 or Zope CVS trunk checkout Documentation: * http://www.zope.org/Members/ajung/TextIndexNG/wiki Download: * http://www.zope.org/Members/ajung/TextIndexNG/ Installation: * The installation is described in the Wiki (see above) Changes sind alpha 1: * complete Registry implementation rewritten. Interfaces for pluggable components are strictly enforced. * every pluggable component resides now in a registry * broken similarity search fixed * additional options for interactiveDemo.py * integrated Matt Hamiltons compressed lists code * changed license of TextIndexNG to ZPL * the queryparser extension module should now build out-of-the-box at least on all Unix plattforms (flex, bison required). * minor code cleanup and speedup in the extension modules Contact: * Andreas Jung, Email: andreas at andreas-jung.com

ZSQL and Order By
by Colin Fox 13 May '02

13 May '02

I want to make a page that shows a list, and allow that user to click on a column of the list and sort the list by that column. It seems to me that the obvious way to do this is to re-issue the SQL command and use a different 'order by'. First - Is this actually the best way to do this kind of thing in Zope? Second - How do I create a ZSQL script that contains a variable order by? Thanks, Colin -- Colin Fox cfox(a)crystalcherry.com CF Consulting Inc.

obtaining properties from next / previous batch sequence-item?
by Uwe Schuerkamp 13 May '02

13 May '02

Hi folks, I am looking for an easy way to access properties from previous or next objects in a <dtml-in>-generated batch output. Background: I would like to put "navigation links" on the bottom of the page, containing the phrase "Next: " and then the property of the next object in question named "caption". Same goes for "previous" and so on. Thanks very much in advance for your time, uwe -- Uwe Schuerkamp Tel: +49 (0)5241 / 80 10 66, FAX: - / 6 23 38 Uwe.Schuerkamp(a)nionex.net Nionex GmbH, IWN5 (http://www.nionex.de/) GnuPG KeyID: 5887047D Avenwedder Str. 55, 33311 Guetersloh GnuPG Fingerprint: 2E 13 20 22 9A 3F 63 7F 67 6F E9 B1 A8 36 A4 61

LDAPUserFolder
by Dirk Datzert 13 May '02

13 May '02

Hi Jens, I thought today about group to role mapping and the zope roles Anonymous and Authenticated. Am I right that Authenticated will be assigned if an user successfully validates against the LDAP server ? Do you think it is possible in LDAPUserFolder / LDAPRoleTwiddler to assign Authenticated only if an user is a member of a special LDAP group ? I came about this point while I develop our intranet with EasyPublisher which has the 4 standard zope roles + 2 roles for workflow and content management: Anonymous, Authenticated, Manager, Owner + Author & Reviewer If I want to restrict visitors on a special folder to view only public material this will be done via standard zope mechanism. If I want to allow a special group on authenticated users to access non public material I have a problem: I want to use standard zope mechanism (like skip_unauthorized). Authenticated users will get the role Authenticated. I can't differ between Authenticated users which have the rights to access the material an Authenticated users which aren't allowed to view the material. One qway out would be the definition of a new role, name it 'Viewer'. But then I have to programm special Role behaviour like <dtml-if AUTHENTICATED_USER.has_role('Viewer')> ... </dtml-if> If I could use the skip_unauthorized feature this would be more general. A possibility to say in LDAPRoleTwiddler something like: If not member of LDAP-group x than not role y. Can you give me your point of view ? Regards, Dirk
