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

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.

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

acl_users
by Sean Duffy 21 Jun '07

21 Jun '07

Hi, I'm trying to do a batch add of users to the standard acl_users folder. Note quite a total success or total failure just yet. First I made a text file (usr_pwd.txt) in the form of password space username. and placed it (temporarily) in the Extensions directory. Then an external method (LoadUsers) to read it: def LoadUsers(self): f=open('/var/lib/zope/Extensions/usr_pwd.txt', 'r') y=f.readlines() return y And a script (user_load): ## Script (Python) "user_load" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## y=context.LoadUsers() for x in y: z=x.split(' ') acl = container.restrictedTraverse( '/foobar/acl_users' ) acl.userFolderAddUser( z[1], z[0], '', '' ) return 0 I hit the Test tab and now I have an acl_users folder full of users with the correct user names, and their passwords show the correct number of characters, however I can't log in using any of the user/password combinations. Should the path '/foobar/acl_users' been simply '/foobar/' or '/foobar' ? Any suggestions? Thanks, Sean

All Of My Zope 2.6 Transactions Since 2/6/07 Are Gone!
by Mark, Jonathan (Integic) 03 Apr '07

03 Apr '07

Zope 2.6.2 on Red Hat 7.3 started acting flaky a week or two ago. It started dying every day or so. Then it lost all transactions since 2/6/07, displaying content as it was two months ago. Then it recovered the lost content, now it has lost it again. Zope Undo shows incorrectly that there were no transactions between 2/6/07 and 3/28/07 when the data loss occurred. What is the best approach to getting this data back?

include?
by Katie 02 Apr '07

02 Apr '07

We're almost finished getting the new site done completely in zope using css and mySql. We have an older portion of the old site done in php thought that we don't really want to re-write. We'd like to include it in the dtml document page that has all the common elements of every page but I'm at a loss of a way to do it other than using an inline frame. Is there a dtml include that takes a url string the way the <dtml-var> tag renders the associated file? Katie

In other words, what should I substitute for X in the following to make this division appear only when a user is logged in? : <div tal:condition="X"> . </div> ~ TIA ~ Ken

getting a unique object id
by David Bear 30 Mar '07

30 Mar '07

I am needing to write an external cache mechanism for rss feeds from zope/plone. My thinking was to use feedparser, then grab the set of object attributes for the item from zope. Then, grab the actual document the feed pointed to and save it. When naming the document that I store locally, I was looking for a simple way to map the zope objectId to the file name hoping it would be unique. However, if this is not unique, is there another attribute from a zope object that I can get that would be? If so, how would I get it? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

Problem with __before_publishing_traverse__
by Peter Bengtsson 30 Mar '07

30 Mar '07

I have a product that looks like this:: class MyApp(Something): meta_type = 'x' def foobar(self): """ doc str """ return "xxx" def __before_publishing_traverse__(self, object, request=None): print "HOUSTON" index_html = PageTemplateFile(...) When I view objects of this class I'd expect Zope to call the __before_publishing_traverse__ hook and print HOUSTON, but it doesn't :( I started fiddling with /usr/lib/zope-2.8.8/lib/python/ZPublisher/BaseRequest.py to try to see what's going on. BEFORE (around line 269):: while 1: bpth = getattr(object, '__before_publishing_traverse__', None) if bpth is not None: bpth(object, self) path = request.path = request['TraversalRequestNameStack'] AFTER:: while 1: bpth = getattr(object, '__before_publishing_traverse__', None) if bpth is not None: bpth(object, self) if object.__class__.__name__ == 'MyApp': print object.foobar() print object.foobar print object.__before_publishing_traverse__(object, self) print bpth path = request.path = request['TraversalRequestNameStack'] When I look at the output of this I get: xxx <bound method MyApp.foobar of <MyApp at /IMS>> None This is on Zope 2.8.8 and I've never had problems with __before_publishing_traverse__ in Zope 2.8's before. Could it be that something in Zope 2.8.8 has changed? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
