The "tal:attribute" tag lets you set the attributes of an HTML element.

If you look at the examples in the Zope book (The latest and greatest is
at http://www.plope.com/Books/2_7Edition), the example is of an "href"
attribute being set: -

<a href="/sample/link.html"
   tal:attributes="href here/sub/absolute_url">

So, the first question might be "how should I put my friends name in
bold?". I'm not sure this is a great example, because bold is a tag, not
an attribute. However, let's say you have decided to use CSS, and so you
want to set the class attribute. A frequent case in which a class is set
as an attribute is setting a different class for odd and even rows: -

<tr tal:define="oddrow repeat/item/odd"
    tal:attributes="class python:test(oddrow, 'oddclass', 'evenclass')">

In this example, a variable is defined ("oddrow") to hold the value
being tested (it could be where you define your friends name). Then the
"tal:attributes" expression sets the value of the "class" attribute to a
value based on a test of the value in the variable.

Translating this into your use-case, you would need to set a variable to
true/false by testing for your friends name, and then set the class
attribute based on that. If the true/false variable was "IsFriend", you
might do (untested): -

<span tal:attributes="class python:test(IsFriend,
                                        'friend_class',
                                        'stranger_class')">
    Your data
</span>

...such that if the variable were true you would get: -

<span class="friend_class">
    Your data
</span>

Yes - "string:" is a namespace declaration, as would be "python:".

Purly? What do you mean? You should always try to restrict
yourself to path expressions, meaning no string: or python:
prefix.

Do your logic _outside_ of your template. (By means of python
scripts)

No, you dont do that with zope :-)
The whole point of zope is to _not_ be able to do that
from aout of the management interface.

You can however use a suid wrapper (sudo) and an
external method.

General zope questions however are to be sent to
the dedicated zope@zope.org list, not ZPT.

Please configure your mail client in any case
to write to mailinglists in text only!

No you cant :) And a page template is the least place to
do so anyway.

You would need an external method for it.

But first rethink if you really can handle that.

If you have your zope only available to your internal
network and/or secure it with ssl. If not, you should
not try such things.

For starters, get some more simple project where
you can get ground on zope development.

Subject: [ZPT] i18n:translate and tal:content should not use template domain
Message-ID: <4371148B.5040906@zope.com>


IMO, if a template an element with both i18n:translate and tal:content
and the value inserted is not a message id, the template's domain will
be used.  This seems like a bad idea.  It can hide failures to provide
message ids because everything ultimately gets a domain.  I'm working on
tools to help people see when text hasn't been internationalized and the
implicit use of of the template's domain makes these tools less useful.

Basically, the domain given in the template source applies to the source
only and shouldn't be used for data coming from elsewhere.

I propose that we should never use the templates domain when inserting data
via tal:content.  Note however, if the tal expression results in the use of the
template's example text, the templates domain should be used.

Thoughts?

Jim

I found a strange thing in ZPT and I'd like you to confirm whether the bug
is in ZPT or in my understanding ...
I'd like to put in the 'value' attribute of an input tag a value depending
on the content of a member variable.

If I use the following code :
<input class="string" type="text" name="last" tal:attributes="value
python:test(request['member']=='NEW','new',request['member'])">
everything is OK and I get the following results :
[path]?member=NEW --> new
[path]?member=member_00000000 --> member_00000000

but if I use the following code :
<input class="string" type="text" name="last" tal:attributes="value
python:test(request['member']=='NEW','new',context[request['member']].LastName)">
I get the following results which are wrong :
[path]?member=NEW --> Error Type: KeyError / Error Value: 'NEW'
[path]?member=member_00000000 --> DE OLIVEIRA

I don't understand why the 'true' part of the test() generated an error
while I have just changed the 'false' part of it (and this 'false' part is
valid as I get a good result when 'member' is not 'NEW') ?

So, is it a bug and if so, is there a workaround ?
Thank you for your help,

Keep in mind that "test" is a standard Python function.
Any standard Python function evaluates all of its arguments before
the function is called.
That's why the "false" part is evaluated even though the "condition" is
true.

Use Python's "and" and "or" operators to get real conditional
evaluation.


Rumours say that Python will finally (probably with Python 2.5)
grow a conditional operator -- lately overdue...
Then the need for "test" and the "and/or" hackery will end...

Yeah, sadly, IIRC, the spelling is horrible :-(

Strictly speaking, "string:" is not a namespace declaration in the
XML sense. Those can only occur before tags or attributes, not
inside the value of an attribute.

In the page template sense, "string:" is a TALES (Template Attribute
Language Expression Syntax).

 From  http://www.plope.com/Books/2_7Edition/AppendixC.stx#1-10

"""
Here is the basic definition of TALES syntax:

Expression  ::= [type_prefix ':'] String
type_prefix ::= Name

Here are some simple examples:

a/b/c
path:a/b/c
nothing
path:nothing
python: 1 + 2
string:Hello, ${user/getUserName}

The optional type prefix determines the semantics and syntax of the 
expression string that follows it. A given implementation of TALES 
can define any number of expression types, with whatever syntax you 
like. It also determines which expression type is indicated by 
omitting the prefix.

If you do not specify a prefix, Zope assumes that the expression is 
a path expression.

The TAL interpretter parses the source of hte ZPT as XML, and so doesn't

Annoying, isn't it? ;-)

But XML knows about "CDATA" sections and an XML compatible parser
should handle them correctly.

which has different escaping (which may actually be desirable) or to
achieve identical escaping,

I had the same idea right after my e-mail to this list, but the RSS feed 
(of which this tag is a part of) worked fine without CDATA. When I build 
the feed with the string expression, structure does not work for me 
(error). And without structure the feed's content starts with a "[" and 
ends with a ">" in my feed reader.

Yes, it treats them "correctly" as CDATA and doesn't look for any tags, 
including tal: inside them...

I'd like to render a macro from python code.
I saw this recipe http://zopelabs.com/cookbook/1015014229 and instead of 
calling the macro_renderer template from  dtml code I can simply call it 
from python (and it works), but is there a more direct way? (something 
like theTemplate.useMacro('macroname',param1='value2',param2='value2')).

The CDATA should definitely not be a requirement, it is basically just
a convenient way of expressing text without having to worry about
escaping your <s, >s and &s. It's possible the construct above gives
an error in your feed reader because the ${...} expression also has a
CDATA section in it, but if you got it to work without CDATA then you
needn't worry about it,

Macros were not designed to be executed by Python Scripts.

You can, however, view them as programs and let them evaluate
by an adequate "TALInterpreter". Not sure, that this is simpler
than your current approach...

Well, let me explain why I want to do that: I'm experimenting with kukit 
and azax (http://bubblenet.be/home/community-work/kukit-azax-details/) 
so I have a macro to be used as intended inside a page template, but I 
want to render the same macro in the (python) method invoked by azax 
(which in turn wraps it in an xml command to send to the browser so that 
it will only update the changed chunk on the page). It's working well 
enough *and* I didn't have to learn javascript ;-)

Then I'll just continue with the current approach ;-)
