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
by Ulla Theiss 17 Mar '09

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.

find zodb object sizes
by Yuri 27 Oct '08

27 Oct '08

Hi! I would like to run a script to see what objects size is, printing the zodb path. analize.py gives me a floating point division error, so I would like to ask if there's a simpler way to see what there's inside the ZODB. Thanks.

hello! everything was working fine until a couple of days ago and now.. Obviously I have no exact traceback of what was done on the machine, but I updated my gentoo box by emerging some apps (nothing apparently involving plone/zope/python/mysql...) :-( Now I really do not know where to bang my head..perhaps on re module?? thanks.. Stefano. when I call the external method zope returns this weird 'error 41': ...

Iowa Python User's Group Meeting (November 3rd)
by Mike Driscoll 26 Oct '08

26 Oct '08

Hi, The next Iowa Python Users Group (AKA Pyowa) is nearly upon us. We will be meeting November 3rd, from 7-9 p.m. at the following location: Marshall County Sheriff's Office 2369 Jessup Ave Marshalltown, IA 50158 At this meeting, we will be having a Crash Course of sorts for all the new programmers in our group. As anyone who has ever taken a programming course know, it is impossible to teach everything in two hours, so we'll be focusing on tools that will allow our group to help themselves. In other words, we'll be focusing on source code analysis techniques like introspection and how to use IDLE effectively. There will also be a presentation on basic GUI design and also Django. We will have 8 laptops there to use for any new people, pre-loaded with Python 2.5.2 and any additional packages we need for our presentations. You are welcome to bring your own laptop if you want. Be sure to have 2.5 on yours as well as wxPython and the PyWin32 package (if you use Windows). We will have them on USB flash drives should you forget. Free pop and bottled water will be provided. Questions and comments can be directed to mike [at] pythonlibrary [dot] org. Updates can be found at http://www.ipug.pythonlibrary.org ------------------- Mike Driscoll Blog: http://blog.pythonlibrary.org Python Extension Building Network: http://www.pythonlibrary.org

Building a site tree with the ZCatalog
by Nico Grubert 22 Oct '08

22 Oct '08

Hi there I use Zope 2.10.5 and I want to create a site tree using the ZCatalog instead of iterating recursive trough the entire object tree. I have the following site structure (all things are folders): - about --- company --- staff ----- homepages ------- phelps --- phonebook --- jobs - research --- ocean ----- atlantic ----- pacific --- lake --- river My ZCatalog contains these entries: - /research - /research/ocean - /research/ocean/pacific - /research/ocean/atlantic - /research/lake - /research/river - /about - /about/company - /about/staff - /about/staff/homepages - /about/staff/homepages/phelps - /about/staff/phonebook - /about/jobs - /about What I need is a list of these entries ordered according to the site structure. I would like to get this list: ['/about', '/about/company', '/about/staff', '/about/staff/homepages', '/about/staff/homepages/phelps', '/about/phonebook', '/about/jobs', '/research', '/research/ocean', '/research/ocean/atlantic', '/research/ocean/pacific', '/research/lake', '/research/river' ] My Zcatalog is configured as follows: Indexes: - path - position - title - id Metadata: - physical_path - title - id The index 'position' contains the a folder's position in it's parent folder. In my example the folder "phonebook" contains "3" for position because it is in the 3rd position inside it's parent folder ("about"). Is it possible to build an ordered site tree with the ZCatalog only and if so, any ideas how I can do that? Regards Nico
