I such a case, you look at the traceback (which you can find in the error_log object in your Zope Root Folder (ZMI)). It just says No exceptions logged. So it does not log any errors in error_log.

Sorry about that.
That is the correct way of calling PageTemplateFile objects in python
code. I've got it working in many places. The error must be either a
new zope bug or something else being wrong. Is your setup as simple as
you've described in the email?
Yes. This is the class I am using:
class TestProd(SimpleItem):
A TestProd object
meta_type = TestProd
manage_options = ( {label: Edit, action: manage_main},
{label: View, action: index_html})
manage_main = PageTemplateFile(templates/mainTestProd, globals())
index_html = PageTemplateFile(templates/indexTestProd, globals())
test = PageTemplateFile(templates/test, globals())
def __init__(self, id, title):
self.id = id
self.title = title
def testit(self, REQUEST=None):
return self.test(self, self.REQUEST, something=blah)
And the test template:
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Strict//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;
html
head
meta http-equiv=content-type content=text/html;charset=ISO-8859-1

pWelcome to tal:block

p tal:content=python:str(options)/
p tal:content=python:len(request.form.keys())/
p tal:content=python:context.absolute_url_path()/
/div
/body
/html
I have added it to the rootfolder in ZMI with the ID testing.
What happens when you in that TAL do something like:
br tal:replace=python:str(options) /
Gives: {'args': ()}
Do the other namespaces work in the page template? Eg. br
tal:replace=python:len(request.form.keys()) / or br
Gives: 0
tal:replace=python:context.absolute_url_path() /
Gives: /testing

So it works just fine in Zope 2.8.0
I suspect that the code you paste was idented wrong because the def
testit() function looked like it was part of the __init__ function.
Yes, the paste was wrong, but there was more than that, I had my editor
slightly misconfigured, which meant that the testit method was done with
tab-indention and the rest of the file with space-indention. After I
fixed that, it worked correctly and something shows up in options. I
am absolutely stumped by why an indention problem can cause such a weird
bug. I would have expected Zope/python to spew out an error telling me
that indention was fucked up. To just silently make things not work is
definitely not nice.
Anyway, thank you so much for your help!

[Zope] Passing args to PageTemplateFile instances
Hi,
I have read some posts about this before, but the solutions given there
does not seem to work for me.
The deal is that I would like to make a product where amongst other
things there needs to be a search feature.
I then make a method that takes input from a form with searchwords but
then I get stuck. How do I get the search results handed over to a ZPT
that will display them?
I would like to just pass the results as an argument to it, and have
made a simple test-product to test how this would work.
class TestProd(SimpleItem):
A TestProd object
meta_type = TestProd
manage_options = ( {label: Edit, action: manage_main},
{label: View, action: index_html})
manage_main = PageTemplateFile(templates/mainTestProd, globals())
index_html = PageTemplateFile(templates/indexTestProd, globals())
test = PageTemplateFile(templates/test, globals())
def __init__(self, id, title):
self.id = id
self.title = title
def testit(self, REQUEST=None):
return self.test.__of__(self)(something=blah)
In the template I should now be able to access options/something
according to previous posts, but this:
span tal:replace=options/something/
results in:
Error Type: KeyError
Error Value: 'something'
I am using Zope 2.8.0. Am I doing it wrong? How can it be done
correctly?

[Zope] Security framework troubles
Hi, I am attempting to make a zope product (a custom book-database for use by my employer) and of course want to secure it. I have added this code to my class: security = ClassSecurityInfo() security.setDefaultAccess(deny) security.declareProtected(View Bookbase, index_html) security.declareProtected(View Bookbase, standard_page) security.declareProtected(View management screens, manage_main) And also of course InitializeClass(Bookbase) When the template tries to access container/title an access denied expection is raised. With VerboseSecurity I get this explanaition: Unauthorized: The container has no security assertions. Access to 'title' of (Bookbase at /bookbase) denied. What exactly am I missing here? It works if I do setDefaultAccess(allow), but I don't want to allow access by default and then just deny for those I know I want to deny access to. I want it the other way around. -- Anders -BEGIN GEEK CODE BLOCK- Version: 3.12 GCS/O d--@ s:+ a-- C++ UL+++$ P++ L+++ E- W+ N(+) o K? w O-- M- V PS+ PE@ Y+ PGP+ t 5 X R+ tv+ b++ DI+++ D+ G e- h !r y? --END GEEK CODE BLOCK-- PGPKey: http://random.sks.keyserver.penguin.de:11371/pks/lookup?op=getsearch=0xD4DEFED0 ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
