Hi, Thank you very much for your answer. As you suggested, i concatenate the string with an integer to create a fieldname and then pass it to zsql object along with language argument. I do everything inside a Script (Python) object that accepts 3 arguments (field,index,language)now. - result=field+str(index) res=context.select_sql(field=result, language=language) print res[0].result return printed - I test this python script inside ZMI and run into problems. It works only if I explicitly specify the columname like "print res[0].author_1". another question- how can one specify row index here?(res[row index]). Each language has one row. thanks _________________________________________________________________ Express yourself instantly with MSN Messenger!

Hi Laurence, thanks a lot for your help. I studied the examples and other programs and did a sort of solution to my problem based on iFrame. Besides, it's always fun to know something new about zope. Thanks again.

dynamically generating sql queries?
by siva k 28 Mar '07

28 Mar '07

Hi, I have five fields in the database author1,author2..author5. Trying to generate a parameter for the select_sql method called result, I run into an error -cannot add type "int" to string. Could you please say how to concatenate a string and a number? please look at the code.. -- <dtml-in "_.range(1,6)"> <dtml-call "REQUEST.set('field','author')"> <dtml-let field=field index=sequence-index result="field+index"> <dtml-in "select_sql(field=result , language=language)" > <dtml-var sequence-key> </dtml-in > </dtml-let> </dtml-in> -- or is there a better way to generate 5 different sql quesries and display the result? thank you. _________________________________________________________________ Express yourself instantly with MSN Messenger!

i18ndude broke my zope 2.8.8
by Peter Bengtsson 28 Mar '07

28 Mar '07

Starting my Zope 2.8.8 development copy was working fine until I [easy_]installed i18ndude. Now I get this:: File "/home/peterbe/zope/zope288/lib/python/TAL/TALInterpreter.py", line 31, in ? from zope.i18nmessageid import MessageID ImportError: cannot import name MessageID That's because of the zope.i18nmessageid that was installed (as an egg) when installed i18n dude. I edited TALInterpreter.py to do this, on line 30: import sys; from pprint import pprint; pprint(sys.path) Now I get the following when I run ./bin/runzope peterbe@trillian:~/zope/zope288 $ ./bin/runzope 2007-03-28 10:00:22 INFO ZServer HTTP server started at Wed Mar 28 10:00:22 2007 Hostname: 0.0.0.0 Port: 8080 ['/home/peterbe/zope/zope288/lib/python', '/home/peterbe/zope/zope288/lib/python', '/home/peterbe/zope/zope288/lib/python/Zope2/Startup', '/usr/lib/python2.4/site-packages/setuptools-0.6c5-py2.4.egg', '/usr/lib/python2.4/site-packages/i18ndude-3.0b1-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.testing-3.4dev_r73174-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.i18nmessageid-3.4dev_r72562-py2.4-linux-i686.egg', '/usr/lib/python2.4/site-packages/zope.interface-3.4dev_r72681-py2.4-linux-i686.egg', '/usr/lib/python2.4/site-packages/zope.tal-3.3dev_r72583-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.deprecation-3.4dev_r73271-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.i18n-3.3dev_r72550-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.schema-3.4dev_r73183-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.component-3.4dev_r72903-py2.4.egg', '/usr/lib/python2.4/site-packages/pytz-2005r-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.event-3.3dev_r72545-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.deferredimport-3.3dev_r72527-py2.4.egg', '/usr/lib/python2.4/site-packages/zope.proxy-3.4.0a1-py2.4-linux-i686.egg', '/home/peterbe/zope/zope288/lib/python', '/usr/lib/python24.zip', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages/Numeric', '/usr/lib/python2.4/site-packages/PIL', '/usr/lib/python2.4/site-packages', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/local/lib/python2.4/site-packages', '/usr/lib/python2.4/site-packages/gst-0.10', '/var/lib/python-support/python2.4/pyinotify', '/var/lib/python-support/python2.4', '/usr/lib/python2.4/site-packages/gtk-2.0', '/var/lib/python-support/python2.4/gtk-2.0'] Traceback (most recent call last): File "/home/peterbe/zope/zope288/lib/python/Zope2/Startup/run.py", line 56, in ? run() File "/home/peterbe/zope/zope288/lib/python/Zope2/Startup/run.py", line 21, in run starter.prepare() File "/home/peterbe/zope/zope288/lib/python/Zope2/Startup/__init__.py", line 98, in prepare self.startZope() File "/home/peterbe/zope/zope288/lib/python/Zope2/Startup/__init__.py", line 257, in startZope Zope2.startup() File "/home/peterbe/zope/zope288/lib/python/Zope2/__init__.py", line 46, in startup from Zope2.App.startup import startup as _startup File "/home/peterbe/zope/zope288/lib/python/Zope2/App/startup.py", line 32, in ? import OFS.Application File "/usr/HOME/peterbe/zope/zope288/lib/python/OFS/Application.py", line 26, in ?

2.10.3: "default" keyword with tal:replace problems?
by Sascha Welter 28 Mar '07

28 Mar '07

Hi Zopistas! Yesterday evening I installed 2.10.3 for some tests with Zwiki (haven't tried any of the other 2.10s). I noticed that the wiki logo wasn't displayed. I think I narrowed it down to the "default" keyword in tal:replace being treated like "nothing". **** My testcase (in a blank ZPT): [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" tal:replace="structure here/notexists|default" />] [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" tal:replace="structure default" />] [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" tal:replace="default" />] **** Expected behaviour: In 2.9 these render to 3 little zpt.gif icons in []. Rendered source: [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" />] [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" />] [<img src="http://127.0.0.1:8080/misc_/PageTemplates/zpt.gif" />] **** What I got: In 2.10.3 this renders to the html source: [] [] [] I tested on two machines, but both Mac OS X 10.4 (one PPC, one Intel), so I'd be glad if someone could try and reproduce it, to see if it's just on "my" OS / machine combination. If it is, I will of course submit it to the Collector. Of course if the expected behaviour has changed, then I must have missed that information. Regards, Sascha

Some __bobo_traverse__ help
by Garito 28 Mar '07

28 Mar '07

Hi! Some one could help me to construct a correct __bobo_traverse__ or wrapper for my necesities. The clues: I have this model of __bobo_traverse__: def __bobo_traverse__(self, REQUEST, nombre): obj = getattr(self, nombre, None) if obj is None: self.REQUEST.set('TraversalRequestNameStack', self.REQUEST["TraversalRequestNameStack"] + [nombre]) if hasattr(self, 'index.html'): return getattr(self, 'index.html ') else: resultado = self.__call__() if type(resultado) == type(unicode()): return WrapperUnicode(resultado) elif type(resultado) == type(str()): return WrapperStr(resultado) elif type(resultado) == type(dict()): return WrapperDict(resultado) else: return resultado return obj With this Wrapper classes: class WrapperStr(str): """ """ __roles__ = None def __bobo_traverse__(self, REQUEST, nombre): obj = getattr(self, nombre, None) if obj is None: return self else: return obj class WrapperUnicode(unicode): """ """ __roles__ = None def __init__(self, cadena): self.cadena = cadena def __bobo_traverse__(self, REQUEST, nombre): obj = getattr(self, nombre, None) if obj is None: return self else: return obj.__of__(self) def __call__(self): return self.cadena def __str__(self): return str(self.cadena.decode('latin-1')) class WrapperDict(dict): """ """ __roles__ = None def __bobo_traverse__(self, REQUEST, nombre): obj = getattr(self, nombre, None) if obj is None: return self else: return obj With this version I have the security problem I'm asking this days. The last opinion was the Wrapper classes are the problem but you could see the wrappers I can do with the information I have But if I change the __bobo_traverse__ to this: def __bobo_traverse__(self, REQUEST, nombre): obj = getattr(self, nombre, None) if obj is None: self.REQUEST.set('TraversalRequestNameStack', self.REQUEST["TraversalRequestNameStack"] + [nombre]) if hasattr(self, 'index.html'): return getattr(self, 'index.html ') else: obj = getattr(self, 'lanzador', None) return obj Where lanzador is a page template with this code: <tal:b tal:replace='structure here' /> Then it works perfect!! (we can conclude, then, that Martijn has good clues about the problem, thanks again!) Here my petition of help: Could someone explain or point me to how the wrappers need to be? I don't like so much the idea that all my work depends on a page template with 1 line of code if I could implement it at product code Thank you! -- Mis Cosas http://blogs.sistes.net/Garito

smart development & debugging
by Roberto Scelzo 27 Mar '07

27 Mar '07

Hi all, we are developing a couple of zope apps which now are becoming pretty complex and, unfortunately, up to now we're developing TTW since we haven't yet find a smart & fast way to do our job avoiding the ZMI. We've searched a lot around but never found a nice guidence or howto... It'll be nice to develop by eclipse... Anyways, since the last upgrade (zope 2.9) even the external editor doesn't work anymore. (sob...) Someone suggested us to use a FS dump product, another one instead pointed us to zope FS products, but, is there any article/howto on how to make group development/debugging of middle/large sized zope apps a nice and confortable experience? Thank you! Roberto ___________________________________ L'email della prossima generazione? Puoi averla con la nuova Yahoo! Mail: http://it.docs.yahoo.com/nowyoucan.html

Cannot Import Base has_attr
by tonylabarbara＠aol.com 27 Mar '07

27 Mar '07

Hi; I had this problem on another server I recently built...and it went away all by itself! I'm now rebuilding my home server, and it's cropped up again. Last time, Maciej Wisniowski suggested I go to a zopectl prompt and type in "import Products.CMFPlone", but apparently that doesn't work on Zope 2.7.8/Plone 2.1.4. Here is the traceback. As per suggestions, I tried the Plone list once again. Nobody responded within an entire week! Somebody responded on this list once before. Since Zope is the foundation of Plone, do you mind that I post here so that I can get an answer? I would really like to get an answer to this. TIA, Tony ________________________________________________________________________ AOL now offers free email to everyone. Find out more about what's free from AOL at AOL.com.

Don't do what? I was about to agree, as I don't think re-releasing under the same version number was correct: the new releases should be 2.9.7.1, 2.10.3.1, or something similary (or bump to 2.9.8, 2.10.4). > this bug is so obvious to catch that I have some serious doubts about > your software testing process. are you releasing totally untested code? > can we trust your releases in the future, will you change sth in your > process? The testing that gets done is not done from "released" tarballs, but from subversion checkouts. This was a bug in the process that created the tarball from a checkout, and not in the underlying Zope software itself. I *think* it also affected only those who build and install Zope as root, although I can't tell for sure, since the tarballs have been replaced. At any rate, I *never* build, install, or run Zope as root, and hence would never have noticed the problem, even if I were doing the releases myself. > Releasing software as a security fix that does not even start makes you > look like a moron, I am sorry to say. Too harsh. Certainly nobody likes having released a "brown bagger", but mistakes do happen.
