dtml-var "sideway" + dot question
by Jordi Yeh 15 Apr '03

15 Apr '03

Hi, I am trying to add a file attachment stored in a LocalFS object using the following code <dtml-with intranet> <dtml-with gracie> <dtml-var file.pdf> </dtml-with> </dtml-with> The above code works, but how can I do the same thing in one line? <dtml-var expr="intranet.gracie.file.pdf"> does not work. Using other words, how can I treat the dot of the id? TIA Jordi

Any Zope Scanner Interface?
by Bobb 15 Apr '03

15 Apr '03

Does anyone have product that will Interface with a document scanner? (Knowing that plan B would be sucking in from the file system). I'm not necessarily looking to store pictures in zope, just Metadata. Thanks in advance. BTW, I sent this to the plone list... FYI there's an article on PLONE on eweek... http://www.eweek.com/article2/0,3959,1019600,00.asp

Error -> A TaintedString cannot be pickled
by Josef Meile 15 Apr '03

15 Apr '03

Hi, this error is really weird. After lots of intents, finally I discovered that it happens whenever I save the sign: "<" in a text field of a ZClass that I implemented. If I don't write this symbol and save the object, it works. I know the code worked before in Zope 2.5.1 because there is one object stored with that string, but when I try to modify it or create a new one (with the string previously mentioned) in zope 2.6.1, I get this error: Error Type: SystemError Error Value: A TaintedString cannot be pickled. Code that caused this TaintedString to be stored should be more careful with untrusted data from the REQUEST. Traceback (innermost last): * Module ZPublisher.Publish, line 150, in publish_module * Module ZPublisher.Publish, line 114, in publish * Module Zope.App.startup, line 182, in zpublisher_exception_hook * Module ZPublisher.Publish, line 102, in publish * Module Zope.App.startup, line 200, in commit * Module ZODB.Transaction, line 235, in commit * Module ZODB.Transaction, line 349, in _commit_objects * Module ZODB.Connection, line 389, in commit __traceback_info__: (('*vg7oXuDosKfgZhLfKvrI/Q==', 'InternshipClass'), '\x00\x00\x00\x00\x00\x07\\\x1d', '') * Module ZPublisher.TaintedString, line 83, in __getstate__ SystemError: (see above) And the external python script that generates it: def modifyJobOfferObject(self,jobOffer,jobTitle,jobDescription,jobCompanyName,jo bCompanyVision,jobPositionOffered,profile,contact,jobCountry,jobArea,email,e ncodedEmail): jobOffer.propertysheets.JobOfferPropertySheet.manage_changeProperties(self.R EQUEST,title=jobTitle,description=jobDescription,companyName=jobCompanyName, companyVision=jobCompanyVision,positionOffered=jobPositionOffered,jobProfile =profile,jobContact=contact,country=jobCountry,area=jobArea,email=email,enco dedEmail=encodedEmail) jobOffer.manage_changeProperties(self.REQUEST,title=jobTitle,description=job Description,companyName=jobCompanyName,companyVision=jobCompanyVision,positi onOffered=jobPositionOffered,jobProfile=profile,jobContact=contact,country=j obCountry,area=jobArea,email=email,encodedEmail=encodedEmail) I've tried anything without any success.

Re: [Zope] Help with session data and redirects
by Brad Powell 15 Apr '03

I believe your hypothesis is exactly right, Chris. I did wget going direct to Zope on port 8080, and I also did wget going through PCGI. Both show the two http requests (and response headers): the first one to sessionCreateAndRedirect and the second one to view_session_obj.pt. Going direct to port 8080 reveals a "Set-Cookie: _ZopeId=..." header being sent only in the first http response; whereas the PCGI route shows the "Set-Cookie:_ZopeId=..." header being sent only in the second response. Also, I tried your workaround, and it works, further confirming the hypothesis. Where do I go from here as far as getting this "bug" fixed? Brad Chris McDonough <chrism(a)zope.com> 04/15/2003 12:24 PM To: Chris McDonough <chrism(a)zope.com> cc: Brad Powell/PPCO@Phillips, zope(a)zope.org Subject: Re: [Zope] Help with session data and redirects FWIW, a workaround for this issue that I just thought of is to put the a session key in the redirect URL of createSessionAndRedirect: session = context.REQUEST.SESSION sessionObjName = 'redirectTest' session.set(sessionObjName, sessionText) url = context['view_session_obj.pt'].absolute_url() dummy = context.ZopeTime().timeTime() browserid = session.getContainerKey() return context.REQUEST.RESPONSE.redirect( '%s?dummy=%s&_ZopeId=%s' % (url, dummy, browser_id) ) The cookie still won't be set under your configuration, but the session machinery exercised by the target of the redirect should always find the browser id in the form namespace instead. - C On Tue, 2003-04-15 at 13:06, Chris McDonough wrote: > That makes me suspect that something about PCGI or IIS is not passing > along the session's set-cookie header to the browser in the initial > redirect response.

CookieCrumbler + ZEO doesn't work?
by Garikoitz Araolaza 15 Apr '03

15 Apr '03

I'm trying to set up an authentication system based on CookieCrumbler in a ZEO cluster. (Zope 2.6.1b2) It works fine in my home server (without ZEO), but somehow, CookieCrumbler fails setting one of the cookies needed for the authentication (I guess....) in the production server cluster. Taking a look at the request, I get something like HTTP_COOKIE '__ac_name="pedro"' in the server where I can't log in (but I can see management pages only once. The first click I do, I have to log in again) and: HTTP_COOKIE'__ac="Z2FyaTTiaXdlcdmk%3D%0A"; __ac_name="gari"; tree-s="eJzTiFfdZ3gasXasdfW/VYHU0ALzsEsQ"' In the server at home (where it works fine) Any hint will be appreciated.

invoking a page template multiple times to display multiple sets of data
by Alec Munro 15 Apr '03

15 Apr '03

I have an array containing two objects of the same type. I have a page template that creates an HTML representation of an object of that type, based on the knowledge that an object of that type will be in variable X . I want both objects to be displayed on the same page, in different places. I could accomplish this by wrapping the page template in a script, telling that script explicitly which object to use, and having the script set variable X to be equal to the object. But so far I have shied away from having a level of python between my page templates. I'm wondering if anyone has another solution to my problem, or can give me information on the advantages or disadvantages of doing it the way I described above. For perspective, the object in question represents an address, and the page I'm having trouble with must display both the shipping and billing addresses. Thanks for your time, Alec Munro

DTML batch processing w/external method

I have an external method which takes two arguments which are equivalent to the start and size attributes of dtml-in. How do I pass the batch variables to the external method? <dtml-in expr="external_method(start,size)" ...> doesn't work (NameError: global name 'start' is not defined).
