Passing the same parameter to all templates or even better the master template

Hi all,

another problem i stumbled upon.

I use the following layout:

<head>

<title>ATF - ${page_title}</title>

</head>

<body>

</div>

<content>Default Content</content>

<p>Messsage</p>

</div>

</body>

</html>

where <content> is replaced by content of other templates:

<?python

layout_params['page_title'] = "Scheduler"

?>

<html py:layout="'template.kid'"

xmlns:py="http://purl.org/kid/ns#">

Hello World

</div>

</html>

What I would like to do is to pass the messages list to the master template without having to specify it each time as it is always the same variable.

Can this be achieved in kid?

Thanks,

Filip

Using jQuery and jQuery UI with Kid templates

Hi all,

I am having trouble to include the jQuery/jQueryUI javascripts in my template.

Here is what my template looks like:

<head>

<title>snomATF - ${page_title}</title>

</head>

<body>

</div>

<content>Default Content</content>

</body>

</html>

Unfortunately the result is that after the template processing it seems that the first script tag is not closed and embeds the remaining part of the page.

So what I see is an empty page.

Can anyone help?

Thanks,

Filip

Patch to properly escape [[< to [[>

Hi,

[[< needs to be escaped to [[&gt; in serialization.py. The attached
patch fixes this and works for people using python-kid on Fedora.

A Fedora bug report with more details is available here:
https://bugzilla.redhat.com/show_bug.cgi?id=528729

Problems with kid templates and python 2.6.5


Dear all,

I have the following issue, with this code:

base.kid
----8<-----
<head py:match="item.tag == 'head'">
        <?python
                title=item.find('title')
                if title is not None:
                        item.remove(title)
                        title = title.text
        ?>
        <title>
                Kieser Training Customer Portal
                <span py:strip="" py:if="title"> - ${title}</span>
        </title>
        <link rel="shortcut icon" href="kieser-icon.png" />
        <link rel="stylesheet" href="base.css" title="Base styles"
type="text/css" />
        <script type="text/javascript" src="js/MochiKit/MochiKit.js" />
        <script type="text/javascript">
        var loading = new Image();
        loading.src = "loading.gif";
        </script>
        <div py:for="node in item" py:replace="node" />
</head>
------8<------

if I compile this and open my page in the web browser I get the
following error:

  File "/usr/local/lib/python2.6/dist-packages/kieser/stat/web/base.py",
line 67, in _match_func
    title=item.find('title')

AttributeError: 'Element' object has no attribute 'find'

As far as I can tell the code that has been generated is faulty. You
cannot use .find on the list that has been generated.

Did anyone else have this problem?

Thanks,

Steve

template compilation logic

Could someone please describe the logic for whether-or-not a new .pyc file is generated before execution? I just ran into a situation where turbogears/kid used a .pyc file that did not correspond to the .kid file in the directory with the same name. I'm not sure, but the mtime on the .pyc file might have been later than the .kid file. The .kid file was installed via an RPM and probably had an old timestamp. I know that with python, the .pyc is recreated whenever the timestamp stored in the .pyc does not exactly match the mtime of the .py file. Does Kid not use similar logic to determine whether-or-not to compile?

Thanks,

Jason

P.S. Many links on the kid home page currently generate the following error:

<type 'exceptions.OSError'>: [Errno 24] Too many open files: '/srv/kid-templating.org/var/trac/plugins'

args = (24, 'Too many open files')

errno = 24

filename = '/srv/kid-templating.org/var/trac/plugins'

message = ''

strerror = 'Too many open files'

Python problem while installing Kid 0.9.6 on FC10 server

Hi,

I'm trying to install Kid 0.9.6.

I ran the command:

./setup.py install

I got the following messages:

running install
error: invalid Python installation: unable to open
/usr/lib/python2.5/config/Makefile (No such file or directory)

Would anyone have any useful tips about what to do to fix this?

Thanks if so, :)

Bug in XML()

Hi!

I just came across a bug in XML().

I was trying to generate shtml includes, so had a line like:

 ${XML('<!--#include virtual="/stations/' + si['OutputDir'] 
+ '/stationMenu.html" -->')}

However, in my processed template, this string would show up:

${XML('')}

I discovered that if you pass a string to XML that has comments in it 
(i.e. <!-- and -->) the evaluation doesn't run and you get the line 
verbatim in your output.

I had to do this:

<?python
var = '<!--#include virtual="/stations/' + si['OutputDir'] 
+ '/stationMenu.html"-->'
?>
${XML(var)}

Strange.

Hi,

I have just seen that the trac installation on kid-templating is not working 
for some reason. I attached the page output (python debug output), so you can 
check it out and hopefully fix it. It says that there is some problem with 
"database disk image".
