Re: tw middleware append genshi filter
Ačiū Dalius for help. This I already made.
But we found how to make it. The problem was tw middleware do genshi
render itself, so it doesn't touch pylons config of genshi.
The result (in middleware.py):
app = make_tw_middleware(app,
{
'toscawidgets.framework':
'pylons',
'toscawidgets.framework.default_view':
'genshi',
'toscawidgets.framework.translator': lazify
(translate),
'toscawidgets.framework.engine_options':
{'genshi.loader_callback':
template_loaded},
'toscawidgets.middleware.inject_resources': True})
there translate is my own translator and template_loaded is appended
filter to genshi:
def template_loaded(template):
Genshi TemplateLoader callback. Inserts the translator filter.
template.filters.insert(0, Translator(translate))
May be it will help to somebody

Hi all,
How to append genshi translator during init of toskawidgets? This
problem comes from custom tw.forms templates. They are not
translating. I feel there should be some simple step.
I'm not sure what you mean by genshi translator but my guess is that you
must use lazystring:
Something like that:
23
http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l23class
CommentForm(forms.ListForm):
24 http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l24
25 http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l25
class fields(WidgetsList):
26 http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l26
name = forms.TextField(label_text = lazystring(_('Name')),
help_text = lazystring(_('Required')),
27 http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l27
validator = UnicodeString(not_empty=True)
28 http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py#l28
)
More code here:http://hg.sandbox.lt/pekla/file/012a56a06089/pekla/lib/forms.py
If that does not help maybe other person will help you here ;-)

pylons and hoteditor
There's a nice wysiwyg/bbcode editor
http://www.ecardmax.com/hoteditor/index.html.
But I'm confused about one thing.
The editor works like that:
td
script
var getdata =[B]Test me[/B];
Instantiate(min,editor, getdata , 600px, 200px);
/script
/td
So the editor will be loaded and the content form getdata will be
added.
But there's one big problem wilt new line and return carriage
characters.
Example:
1. Enter characters in new lines
a
b
c
2. Save it into db as bbcode.
It will be saved as a \n\r b \n\r c - of course \n\r will not be
visible as string '\n\r'
3. Then I want to load that content to the editor from DB
var getdata =${h.content_form_db};
Instantiate(min,editor, getdata , 600px, 200px);
And here's the problem, generated code looks like that:
var getdata =a
b
c;
Instantiate(min,editor, getdata , 600px, 200px);
So it's not a valid js code and it will fail.
Ok so I've done something like that:
Before i save bbcode content to db i replace \n to \\n and remove all
\r.
This works and now the generated code looks like that.
var getdata =a\nb\nc;
Instantiate(min,editor, getdata , 600px, 200px);
But there's a new problem.
If a user will put into editor '\n' or '\r' string my replace method
will fail...
Any suggestions?

clean up after session finished
Hello all, I am new to pylons and want to develop an app which generates some images. For each session I generate a folder to contain the images for this session, which the user then can download. I want the folder and the images to be deleted when the user closes the browser. Is there a way to do this? Am I missing something obvious?

Re: Pylons reload signal?
On Wed, Feb 4, 2009 at 12:36 AM, Kevin Baker kba...@missionvi.com wrote: So are you saying that it is doing a restart when it detects a change... not just reloading the conf? If that is the case I guess I can just restart. I am trying to reload with as little impact on uptime as possible. With apache I do a /etc/init.d/apache2 reload rather than restart for the same effect. Yes, that's how it works. Apache actually works similarly, but it's a multi-process system -- when it reloads the configuration it makes sure all incoming requests are finished, holds any new incoming requests, and kills all the child processes and then new processes are made with the new configuration. If you have a process in front of the Pylons process you can avoid interruption, so long as the thing proxying to the process will do a retry. I don't think mod_proxy does this, but FastCGI/SCGI and maybe some other setups will do so. -- Ian Bicking | http://blog.ianbicking.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

You could use WSGIDaemonProcess to create an additional daemon process and then use WSGIImportScript to preload script that triggers background thread to do any periodic processing. This daemon process wouldn't be used to handle requests, just to do background stuff. If only using a single process in daemon process group to handle requests, you could always just run the background thread in it. You only need a separate daemon process dedicated to it when using embedded mode or daemon mode with multiple processes in daemon process group.

Pylons on CYGWIN
For people developing on Windows, Cygwin is a valuable tool, but beyond having access to unix shell utilities, you can also install some advanced software packages on Cygwin, like Python, Ruby, SQLite, etc. In fact it's possible to install Pylons and use that instead of using the regular windows Python installation. Does anyone have any experience with this kind of setup ? I assume the performance would be bad since most apps running on Cygwin are slow (possibly due to the overhead of linux-windows system call translation) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.
