is there a zope product for generating spreadsheets?
by Krishnakant 05 May '09

05 May '09

hello all, I am right now browsing through the grok tutorial and found it to be really amaising. I had been confused a few days regarding how I can put my application into zope. Thanks to all you who patiently answered my queries. Now I am wondering whether there is a product which can generate spreadsheet like output for some typicle data such as balance sheets or ledgers (with cell merging capability)? I would also like to know if there is some way I am make grok integrate open office in a way that I can generate open office spreadsheets and send it to a browser or open it in some way? I know there is a python library called odfpy which can fill up spreadsheets with data, but I don't know whether similar things are possible with zope. I have searched but did not find some thing like this. so is any thing of the above possible? happy hacking. Krishnakant.

How to use ZPT with ad-hoc context?
by Daniel Dekany 04 May '09

04 May '09

How to create a template context ("here" inside ZPT) that is not an object from the ZODB, just a temporary object? This is what I tried: class AdhocContext(Implicit): pt = PageTemplateFile("whatever/path", globals()) ... MyZopeProduct: def whatever(self): "Test" ctx = AdhocContext().__of__(self) return ctx.pt() The problem I have with this is that I can't access anything in AdhocContext from the ZPT because the security manager blocks it (I didn't forget to security.declarePublic + document what I wanted to access). Is there a simple trick to solve this? (BTW, I will need to invoke some Plone macros from that ZPT too... I hope that will just work if this security matter is solved.) -- Best regards, Daniel Dekany

can I use my existing twisted rpc app in zope.
by Krishnakant 03 May '09

03 May '09

hello all, I am new to this mailing list and pritty new to zope as well. I have been reading the zope wiki and trying to find many answers to all the questions I have about this very powerful application server. My first question is, should I use zope 2 or zope3 for a financial/ accounting software? I am not intending to develop just a web site but a complete web application which will be used in fields like Point of Sales and micro finance. I feel I must go for zope 3 because the wiki says that zope3 is targeted at application developers for the web. But at the same time I am unsure whether zope3 has products for tasks such as open office integration and call to a database. This brings me to the second and the main question for which I am writing this email. I have a team of python developers working on the core logic of the system and they have already written an RPC based server application containing the entire core logic. Right now we use a gtk based thin client to make calls to the rpc server based API. I would be interested to know if I can directly take this twisted based rpc server application and put it inside zope. What I mean is that I would like to directly integrate my already developed rpc server application inside zope in such a way that it sits in the server and I can let people write clients to make calls on the server either through other zope products as clients or any other language. So is this possible and should zope3 be the right choice for this? happy hacking. Krishnakant.

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

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
