Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

auto login user

How could I automatically/programmatically log in an existing user when anyone visits a zope site? I am doing this because I want to demo an application on the web without needing a login. I am using an authenticated user in the application to retrieve data from a database that is specific to that user. Regards Garry

zope2, buildout and relstorage
by Jürgen Herrmann 30 Apr '09

30 Apr '09

i want to use relstorage with zope 2.10 and have read about the "fake egg" procedure at http://pypi.python.org/pypi/plone.recipe.zope2install is there any documentation how to use that recipe? i tried downloading and unpacking from http://pypi.python.org/packages/source/p/plone.recipe.zope2install/ but i'm, a bit lost there. from the readme i read that i should run "python2.4 bootstrap.py" first, and then? obviously the shipped buildout.cfg puts a zope2 source tree in parts/zope2 after running bin/buildout. the "eggs" dir contains: plone.recipe.zope~all-3.0-py2.4.egg setuptools-0.6c9-py2.4.egg zc.buildout-1.2.1-py2.4.egg and fake-eggs has: Acquisition/ zope.app.renderer/ ClientForm/ zope.app.rotterdam/ DateTime/ zope.app.schema/ docutils/ zope.app.security/ ExtensionClass/ zope.app.servicenames/ mechanize/ zope.app.session/ Persistence/ zope.app.site/ pytz/ zope.app.size/ RestrictedPython/ zope.app.skins/ tempstorage/ zope.app.sqlscript/ ZConfig/ zope.app.testing/ zdaemon/ zope.app.tests/ zLOG/ zope.app.timezones/ ZODB3/ zope.app.traversing/ zodbcode/ zope.app.tree/ Zope2/ zope.app.undo/ zope.annotation/ zope.app.wfmc/ zope.app/ zope.app.wsgi/ zope.app.annotation/ zope.app.zapi/ zope.app.apidoc/ zope.app.zopeappgenerations/ zope.app.applicationcontrol/ zope.app.zptpage/ zope.app.appsetup/ zope.cachedescriptors/ zope.app.authentication/ zope.component/ zope.app.basicskin/ zope.configuration/ zope.app.broken/ zope.contentprovider/ zope.app.cache/ zope.contenttype/ zope.app.component/ zope.copypastemove/ zope.app.container/ zope.datetime/ zope.app.content/ zope.decorator/ zope.app.content_types/ zope.deferredimport/ zope.app.copypastemove/ zope.deprecation/ zope.app.datetimeutils/ zope.documenttemplate/ zope.app.debug/ zope.dottedname/ zope.app.decorator/ zope.dublincore/ zope.app.dependable/ zope.event/ zope.app.dtmlpage/ zope.exceptions/ zope.app.dublincore/ zope.filerepresentation/ zope.app.error/ zope.formlib/ zope.app.event/ zope.hookable/ zope.app.exception/ zope.i18n/ zope.app.file/ zope.i18nmessageid/ zope.app.filerepresentation/ zope.index/ zope.app.folder/ zope.interface/ zope.app.form/ zope.lifecycleevent/ zope.app.ftests/ zope.location/ zope.app.generations/ zope.modulealias/ zope.app.http/ zope.pagetemplate/ zope.app.i18n/ zope.proxy/ zope.app.interface/ zope.publisher/ zope.app.intid/ zope.rdb/ zope.app.introspector/ zope.schema/ zope.app.keyreference/ zope.security/ zope.app.layers/ zope.sendmail/ zope.app.locales/ zope.server/ zope.app.location/ zope.size/ zope.app.mail/ zope.structuredtext/ zope.app.onlinehelp/ zope.tal/ zope.app.pagetemplate/ zope.tales/ zope.app.preference/ zope.testbrowser/ zope.app.preview/ zope.testing/ zope.app.principalannotation/ zope.thread/ zope.app.publication/ zope.traversing/ zope.app.publisher/ zope.viewlet/ zope.app.rdb/ zope.wfmc/ how do i move forward from here? how to use that source tree and how to install relstorage into it? thanks in advance and best regards! jürgen -- >> XLhost.de - eXperts in Linux hosting ® << XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Boelckestrasse 21, 93051 Regensburg, Germany Geschäftsführer: Volker Geith, Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)700 XLHOSTDE [0700 95467833] WEB: http://www.XLhost.de IRC: #XLhost(a)irc.quakenet.org

how to prevent URL access to an external method?
by Pedro LaWrench 28 Apr '09

28 Apr '09

I need to do something on the filesystem, which requires unrestricted python, so I created an external method. The problem is that anyone can call that directly via URL, so I added a permission check. Even then, users with the sufficient permissions can call this via URL, which I don't want them to do. I only want them to have access indirectly from other pages (such as a page template that will pass sane parameters). Is there anyway to do this? Thanks, PL

Are there Zope product > examples out there that fit the bill? Hi, I once was involved in developing a system that supposedly should be able to handle a very big number of objects. They chose to put all the base objects into mysql too, and use mysql for object lookup. I do not know what type of benchmarks they did to conclude that this was the best choice. But they regulary did queries for which relational databases were made. If your data contains lots of small items, that are all similar of content, and you want to do queries that involves many of these attributes, you might want to take a look at orm tools. relstorage will not help you with your queries, because it stores everything as a pickle, afaik. I suggest you experiment a bit. Create 100 million objects, and do some of the actions you are planning to do on them. Best regards, Patrick

Building a fast, scalable yet small Zope application
by Morten W. Petersen 27 Apr '09

27 Apr '09

Hi, I'm considering building a large scale, but small in features site. It will contain lots of small objects (millions, tens of millions, hundreds of millions) of objects, where each object has a couple of strings and maybe some other light attributes. So far, I've been contemplating disabling undo (if that's possible), and using BTree structures, maybe segmenting objects into different groups (folders) to further speed up lookups. Scalability is also an issue, should I consider using RelStorage? Should I consider using the ZCatalog for faster lookups? Has anyone else developed something similar? Are there Zope product examples out there that fit the bill? -Morten -- Morten W. Petersen Manager Nidelven IT Ltd Phone: +47 45 44 00 69 Email: morten(a)nidelven-it.no
