Re: [Zope] convert python to dtml

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

read-only-database

Hello list, I want to run the database in read-only mode from CD and configured it accordingly in the zope.conf: read-only-database on enable-product-installation off zserver-read-only-mode on Starting Zope, I get the following error: Traceback (most recent call last): File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ? run() File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 21, in run starter.prepare() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 98, in pre pare self.startZope() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 257, in st artZope Zope2.startup() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 47, in sta rtup starter.setConfiguration(cfg) File "D:\Programme\Zope\lib\python\Zope2\App\startup.py", line 56, in startup File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 96, in getDatabase File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 113, in _createDataba se File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 163, in o pen DB = self.createDB() File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 160, in c reateDB return ZODBDatabase.open(self) File "D:\Programme\Zope\lib\python\ZODB\config.py", line 97, in open File "D:\Programme\Zope\lib\python\ZODB\config.py", line 133, in open File "D:\Programme\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 112, in __init__ File "D:\Programme\Zope\lib\python\ZODB\lock_file.py", line 57, in __init__ IOError: [Errno 13] Permission denied: '\\Zope-Instance/var/Data.fs.lock' r+ means opening the file for updating. This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

Yup, that and Squid 3's "not production quality" status makes the whole Squid/ESI thing a total non-starter, which is a shame... ...but I do wish, as a result, that people would stop touting it as a way to scale Zope apps. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

silly DTML question: "in" test
by Bill Seitz 10 Dec '07

10 Dec '07

I'm trying to do something in a DTML-Method (in ancient Zope 2.6.2) that seems like it should be really simple, but I can't get it right. I want to see if a value (defined via url-arg) is in a list which is generated from an RDBMS query (field type=integer). The pseudo-code would be something like: if foo in (select foo_col from table where x=y) then z='t' else z='f' I tried putting the simple SELECT query into a zSql and then calling it like: <dtml-call "REQUEST.set('foo_list',IfShowNextDoor())"> <dtml-if expr="foo in foo_list"> <dtml-call "REQUEST.set('z','t')"> <dtml-else> <dtml-call "REQUEST.set('z','f')"> </dtml-if> But that doesn't work.

Five 1.5.5 and menuItem - problem with 'filter' parameter
by Pawel Lewicki 01 Dec '07

01 Dec '07

Hi, Am I doing anything wrong or filter parameter of browser:menuItem is just ignored? I have that problem in Plone but I suspect CMF ActionsTool if not Five itself. <browser:menuItem for="Products.Archetypes.interfaces.IBaseObject" menu="object" title="synchronize" action="synchronizeObject" permission="cmf.ModifyPortalContent" filter="string: object/whatever" /> I tried "whatever" Python Script, registered page view, etc. No success.

Response to Matijn Faassen Grok/Zope 2 question.
by Rene B 29 Nov '07

29 Nov '07

Thanks for the feed back. I didn't expect the responses i got from a post placed. I like some of the suggestions. Some one mentioned he used Zope 2 as a "container" for his Python scripts. He used Python as much as possible for logic and sparingly used DTML and ZPT to view the results. i like this approach. I'll stick with Zope 2 to continue the learning curve. I wanted to answer some questions asked by Martijn Fassen regarding grok and what I liked about Zope 2. I do like the Zope 2 ZMI. It helps organize visually your MVC. I do like coding TTW and seeing a template file or controller all organized in a project directory and testing live just by clicking the link. I also like the "ADD" feature. It list all the products/components you can add. It would be nice to have this in Grok since i don't know what is out there to add and what they do. And "add" feature with a description/docs and simple code example would be nice. Example would be the the "formlib". a database connection(relational) helper would be helpful too. I don't think i'll be diving into the ZODB right now for 2 reasons. There isn't a whole lot of ZODB docs and what happens if i create a project at work ( i,e, asset tracking ) and the other programmers in the office only know SQL . If i have all me data is in ZODB how will they be able to get at it? If the asset tracking app grows i know these other programmers will wont to get to the data to do some adhoc report. I'll be cooked if they can't get to it via SQL. Unless there is a way i have not read about yet! Maybe someone should write some reverse ORM to translate SQL and query a ZODB database!!! stupid i know. I will go through the Grok Tutorials again. i did have a problem with installation. "zope3recipes\winctl.py line 28" no module named win32api. i may have missed some prerequisite. I'll have to go through it again. Zope 2 had a nice windows install .exe package!!!!!!! The tutorial did have a few steps wrong. Naming the projects and packages come after module name and username and password. Not a big deal but i thought i would mention it. my Grok install ended up in c:\python24\scripts\sample it would be nice if Grok was installed in its own self contained directory with a self contained version of the required python version. Just nice to keep it isolated from python 2.5 +. The more docs and tutorials the better. Nothing in my opinion is more important to learning and sticking with a platform. if you run out of docs and tutorials to grow on you get soured quickly. once last thing about the ZMI and if it were to make its way to Grok ( even partially)! why not have the GMI add some code for you automatically like : import Grok Class Sample(grok.Application, grok.Container): pass Class index(grok.View): pass It would save typing if we could click "New App" and enter "Sample" and have the MI add the rest of the small code. Mabe i'm being lazy but Zope 2 seemed to hide this from you. same with the rest of the controllers and templates "add" "controller" enter "index". the rest of code is genersted. "add" "template" template name index.pt.

Portal catalog not always finding my content type
by Maurits van Rees 29 Nov '07

29 Nov '07

Hi, In some test code I add a custom content type called School. Then I check if it has been added to the portal catalog. And I call a function in a PAS plugin that searches for a School within the catalog and does something with that. This all works. Tests pass. I am happy. But in practice it somehow does not work. In the portal_catalog within the ZMI I can clearly see that a School is present in the catalog. But the code in my PAS plugin does not find it. And in a zopectl debug session I also cannot find it. Here is some code I use. Product is another custom content type. cat = getToolByName(self, 'portal_catalog') assert(len(cat()) > 5) assert(len(cat(portal_type='Product')) > 5) assert(len(cat(portal_type='School')) > 0) The first two assertions pass, so the catalog seems to be functioning properly. The last assertion fails. Can anyone think of a reason why this could happen? Should I add some more parameters to the catalog call? Should I use searchResults instead, or queryCatalog? This is on Plone 3.0 btw, with Zope 2.10.5. CMFPlone overwrites the default CatalogTool from zope, so I thought about asking on a plone list instead. But since it *does* go correct in the tests I thought it was probably not something Plone specific. Feel free to direct me to a different list though. :) Thanks, -- Maurits van Rees | http://maurits.vanrees.org/ [NL] Work | http://zestsoftware.nl/ "Do not worry about your difficulties in computers, I can assure you mine are still greater."
