what about something like:

   );
<tal:block replace="structure string:</script>" />

Subject: [ZPT] Newbie Question
Message-ID: <008e01c3be39$bab84e40$6501a8c0@HP751N>

I am very new to Zope and have a few questions for the list.

My partlially redesigned website can be viewed here:
http://horn.digimark.net:8080/Butterflies.com/products/010_artwork
 
I need to create a page view for my product subdirectories that have 2
columns.
1st column would contain the small image as is currently being displayed

along with a 2nd column which would contain a description of it's
contents.

So in the case of Artwork the subdirectories would look like this:
Image       Exotic butterflies encased in elegant acrylic displays
Image       Framed Tropical butterflies from the Peruvian Rainforest

The items within the subdirectory would look the same as above.
This would give the pages some balance and not so one-sided.

The ideal solution would be to have the page list 20
items/subdirectories 
split between two colums with text below each item, but this might be
asking for too much right now.

Any help or suggestions would be greatly appreciated,

Thanks in advance,

Hi

I am trying to find out how to send an email with a text file attachment
from a Python Script. I can find information on how to do this using
DTML but not for a Python Script.

Can anyone point me to an example of how to do this?


Many thanks

Two options:

  *  do it in DTML (the easiest)

  *  use Python's "email" package (part of version 2.2 and above
     but will work with Python 2.1.3, too)
     to generate the finished email message text
     and then use "MailHost.send" to send it.

     You will need to allow import of "email" and use of its
     classes for Python Scripts (--> "README.txt" in "Products/PythonScripts")

Subject: [ZPT] Unicode error in PageTemplates/XML
Message-ID: <1071504360.1609.14.camel@a700>

Hi all,

I've a problem using Zope Page Templates to generate XML content with
8bits-strings.  Here there is a minimalist example of what happens:

give_me_content (Python Script):
return 'ma?'

test_html (PageTemplate):
<html>
  <body tal:content="here/give_me_content" />
</html>

test_xml (PageTemplate):
<?xml version="1.0" encoding="ISO-8859-15"?>
<doc xmlns:tal="http://xml.zope.org/namespaces/tal">
  <body tal:content="here/give_me_content" />
</doc>

test2_xml (PageTemplate):
<?xml version="1.0" encoding="ISO-8859-15"?>
<doc xmlns:tal="http://xml.zope.org/namespaces/tal">
  <body>ma?</body>
</doc>

standard_error_message:
<error>
  <dtml-var error_tb html_quote>
</error>

test_html works fine.  No problems here.
test_xml causes an error "UnicodeError: ASCII decoding error: ordinal
not in range(128)".  My surprise is that test2_xml works fine, so it
seems to be a problem of TALES.  I've tried to encode the result using
UTF-8, but doesn't works.  It seems that only 7bit strings are allowed. 
I've also tried to debug PageTemplate.py code, but I'm not able to find
where the problem is.  Perhaps this is a problem of standard StringIO
module, but then, why it works in HTML?

Anybody knows something about this?  I'm really interested into generate
XML using TALES, but I need to be able to generate LATIN encodings.

Thanks in advance

I am surprised, too.

The error means, that the page template sees Unicode somewhere
(I do not see where). It then tries to convert everything to
unicode. Unless you set Python's default encoding (with
"sys.setdefaultencoding" in "site_customize.py"), this will
only work for ASCII strings.

I would set the default encoding (frowned about by many Python gods).
When you want to be more in line with best
practices: ensure you work throughout with Unicode
and set the correct "Content-Type" (the ZPublisher will then
encode the Unicode result correctly).

Message-ID: <005201c3c35d$0fbd60b0$0500a8c0@VAIO>

Hi, I'm fairly new to Zope and am trying to learn to use ZPT rather than
DTML.

I'm using a "Sequences" Product as a primary key generator. I have created
an instance of this called "pkGenerator" in the same folder as my page
template. If I want to get the next sequence value I can call a DTML method
(called "sequencePuller") containing simply this:

     <dtml-var "pkGenerator.getNextValue()">

which works when called from the following line in a form on my template:

    <input type="hidden" name="pk" tal:define="primaryKey
here/sequencePuller" tal:attributes="value string:$primaryKey" />

This seems like an awful hack to me, and I'd like to do it in entirely in
TAL/TALES. I want to do something like:

      <input type="hidden" name="pk" tal:attributes="value
pkGenerator.getNextValue()" />

but that doesn't work. I get a compilation error:

      TAL.TALDefs.TALError: Invalid variable name
"pkGenerator.getNextValue()" in expression 'pkGenerator.getNextValue()'...

 Does anyone know if/how I can do this?

You should use a Unicode string here:
	return u'ma\N{LATIN SMALL LETTER O WITH ACUTE}'

Otherwise, I'm not sure what character set that string will
actually end up in (in a default Zope, probably ISO-8859-1).

Your xml would then look like:

<?xml version="1.0" encoding="ISO-8859-15"?>
<doc xmlns:tal="http://xml.zope.org/namespaces/tal">

     <tal:b condition="python:request.RESPONSE.setHeader(
		'Content-Type','text/xml; charset=ISO-8859-15')" />

   <body tal:content="here/give_me_content" />
</doc>


The tal:b bit sets the content type header with an explicit charset,
which Zope uses to encode the result. Zope does not (yet) pick
up the 'encoding=' element of the XML header.

You get those error messages if you mix Unicode strings with encoded
strings. On the page template's edit screen, if you set the content-type
of the page template to text/xml stricter XML validation kicks in, which
might be triggering it. As Page Templates is a fully Unicode aware
product, this could be considered a feature (and your test_html working 
a
bug).

Use Unicode strings instead of latin encoded strings. If your data 
source
is latin encoded, you might need to do "unicode(data,'iso-8859-15')" to
convert your data to a Unicode.

Thanks.  I will not send the resultant xml to the user (it is part of an
OpenOffice document), but this is great to know.

It works fine !!  Now it seems obvious: all the page template is unicoded
before parse its xml, so use of encoded data crash.

Thanks very much for your help.

Hi Tom,

 ... seems someone fooled You with some different "Reply-To" header,
or did You post this intentionally to the zpt-list?

Anyway, the right syntax of:

 is most probably:

<p tal:repeat="foldo python:here.objectValues(['Page Template', 'Image'])">

In Plone's main_template there are the following lines:


   <metal:block fill-slot="css_slot">
      <metal:block define-slot="css_slot" />
   </metal:block>



Can someone explain the purpose of the define-slot statement
inside the fill-slot? Is it to serve as some sort of default
definition?

The "real" define-slot for css_slot is in header.pt as
expected, so what's the purpose of this one?  As I understand
ZPT, even if css_slot weren't defined in header.pt, no error
would be thrown even if the above trick define-slot weren't
used.

When you use a macro, every slot in the macro is filled either with 
explicit fill-slot statements or with the default slot contents from the 
definition.  Therefore, if you are "refining" a macro by using it in 
another macro definition, and you want to pass the slot through 
(allowing it to be filled by users of the new macro), you need to 
re-define the slot.  Unfortunately, the current TAL code can't handle 
re-defining a slot on the same element that fills it.

Evan @ 4-am

Nguyen, Joe asked the ZPT mailinglist about the following:

there is some implicit magic for 'self' with external methods. To make
sure all is explicit, pass in 'context' as the first argument:

I believe this should work (untested):
context.yourExternalMethod(context, arg1, arg2)

I believe there is more on the subject here :

:)

note:
  This is really a question for the Zope mailinglist, not the ZPT one.

Subject: [ZPT] Globals from calling script
Message-ID: <3FE2FA42.5010306@xfr.co.uk>

Hi List,

I have a script which is calling a ZPT containing a form. The form 
submits to ".", which I understand to mean "me", and formulator checks 
it. If there are no errors, the script calls another ZPT. If there are 
errors, the script puts them in a dictionary and re-calls the first ZPT.

My problem is that I can't figure out how to display my dictionary in 
the ZPT - whatever I try, I get either a "key error" or a "global not 
defined".

The ZPT does not seem to have access to the same name space as the 
script, and if I use tal:define global I seem to be wiping out my 
dictionary. I'd naively though that by calling the ZPT from the script I 
had a single "environment". The alternate strategy I have tried is to 
call the script as the ZPT loads, but if I do this I can't figure out 
how to exit the form and return to the top-level script.

Can anyone give a clue?

FWIW, at this point I would rather be able to access Formulators errors 
directly from the ZPT, and would rather have my logic in the /calling/ 
script than a /called/ script - is this possible?

You want to learn about the "python" TALES expression type
(--> Zope Book).

Short: '...tal:attributes="value python: pkGenerator.getNextValue()"...'
will work.

This is wrong. "." means the parent. "" means the same document
but this is handled wrong by many browsers in some circumstances.
Thus, do not rely on it.

This is indeed the case (and very wide spread in programming).

Such a techique is called dynamic binding and is highly error prone.
Most (compiled) programming languages use static bindung:

  You can determine which variables are visible by looking (statically)
  at the code. It is not relevant how the function was called.

Python is such a language.

You must pass your dictionally as argument to your ZPT.
Inside the ZPT, you can access it via the predefined
"options" variable. Read the Zope Book, for details...
