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.

Anyone know of a tool to restore/cleanup/reset security/role settings?
by Ross Patterson 01 Dec '08

01 Dec '08

Does anyone know of an existing tool for restoring all security settings/rolemaps from the ground up? Obviously I can use rolemap.xml where applicable and update workflow security. I want to first restore the Zope root to code defaults and restore the whole hierarchy to just acquire. I'm going to write something myself if not, but I thought I'd see if there was anything out there. Ross

You are right. Almost surely, you see a "Five" bug: "Five", too, should respect "enable-product-installation". You can see the right transaction handling in "OFS.Application.install_product' -- somewhere near the buttom of this function. Maybe, you correct "Five" accordingly. >Any idea why this is happening to me >and doesn't seem to be a common problem >others come across? "ConflictError"s are apparently nondeterministic errors -- they only occur when concurrent transactions conflict with one another. Apparently, in your setup, the conflict probability is especially high (maybe because it is especially expensive to register your package). In principle, others are threatened as well if the are using "registerPackage". I do not have Zope 2.9 with its "Five". In Zope 2.11, the "Five" code appears to have been cleaned up. This means, upgrading to Zope 2.11 may be another option for you. -- Dieter

Where is my BtreeFolder stored?
by Mr SZ 29 Nov '08

29 Nov '08

Hi All, I can now create BTreeFolders and add,remve items to and from it but how and where does zope store my folders,does the id indicate the folder I'm storing in? This is in an external method: def test3(): f = BTreeFolder2('sufest') f2 = BTreeFolder2('somefolder') f3 = BTreeFolder2('somefolder2') f._setObject(f2.id, f2) f._setObject(f3.id, f3) uniq_id = f.generateId() obT = OOBStuff(uniq_id,{'a':1,'b':2}) f._setOb(uniq_id, obT) lst = f.objectItems() return lst def test4(): if 'suftest' in aq_parent.objectIds(): return 'True' class OOBStuff(BTreeFolder2): meta_type ='OOBStuff' def __init__(self, oid,dict_to_add): super(OOBStuff, self).__init__(oid) self.item = OOBTree() self.item['Auth'] = dict_to_add def return_Tree(self): return self.item Running test4 gives this error: Error Type: AttributeError Error Value: 'builtin_function_or_method' object has no attribute 'objectIds' Also, how come my BTFolder didn't show up anywhere in the ZMI? I have imported aq_base and aq_parent. Regards, sz " life isn't heavy enough,it flies away and floats far above action" Start your day with Yahoo!7 and win a Sony Bravia TV.
