Re: Unicode problem with myt template...
Hi!
I found the solution:
def _ResponseAsString(self, Resp):
ps = Resp.content[0]
ps = ps.decode('utf-8')
return ps
def _RenderContent(self, Content):
c.PageContent = Content
self._BuildMenus()
rp = render_response('/pagetemplate.myt')
return rp
def _RenderContentFromTemplate(self, Templ):
PageContent = render_response(Templ)
PageContent = self._ResponseAsString(PageContent)
return self._RenderContent(PageContent)
def _SimpleRender(self):
path = dwfmt.ToAscii('/' + self.Controller + '/' + self.Action
+ '.myt')
return self._RenderContentFromTemplate(path)
These methods working in both of WinXP_HU_Prof, and Win2K3_En_Serv
machines...
Important: it needed to convert all of the c. rendering constants
to unicode like this.
% ToUnicode(c.PageTitle) %
def ToUnicode(s, encoding = None):
'''
Converts a string to unicode.
'''
S_typ = type('')
U_typ = type(u'')
if not (type(s) in [S_typ, U_typ]):
s = str(s)
if type(s) == S_typ:
if encoding == None:
encoding = _Locale[encoding]
s = s.decode(encoding, 'replace')
return s
def ToAscii(s, encoding = None):
'''

S_typ = type('')

Using encoded forward slashes in a URL?
Hi all,
I'm having a problem with encoded forward slashes in a URL. That is,
I need to pass an 'id' that has encoded forward slashes in its name,
but this results in routes not being be able map the URL: apparently
it sees another subset of paths in the URL, even with the slashes
encoded as %2F.
As an example, this is the actual URL called:
http://127.0.0.1:5000/finder/select/R%2F2007%2F23
and this is my routes setup, very basic:
map.connect('error/:action/:id', controller='error')
map.connect(':controller/:action/:id')
map.connect('*url', controller='template', action='view')
The call never arrives at 'def select()' in 'class FinderController',
but results in a 404. Leaving out the %2F characters works fine
(other than that it doesn't result in the intended output from the
controller, but well).
Is there something missing in the routes setup, or is my way of
thinking incorrect? This should be the way to pass forward slashes to
a URL, right?
Thanks,
Evert

Re: lowercased response headers
This was a bug in my head(which seems to be the source of most of them). I should have known better than to run off on a wild header case goose chase. My web development work has been infrequent the last few years. I'm guessing from JJ's response he's wondering what I'm up to with this funkyheader :) ? I have some large files 500MB+ I serve out of an app running pylons behind lighttpd. My access control/meta data/versioning code is over in pylons but but serving files that size via proxy or fastcgi has been bad. The header X-LIGHTTPD-send-file: /Users/kai/Documents/vimbook-OPL.pdf is an instruction to lighttpd to toss the body of the response returned by the upstream server (pylons in this case) and instead serve the file from disk. This sped things way up for me. The source of the problem ended up being that I needed to send a content length or lighttpd refused to take action on the header. It didn't matter what I set the value of the header to be as long as I set it to a number (-1, 536870912, ... ). Sorry this is not very pylons related but I figured someone serving large files from a pylons/wsgi app might find this info useful.

Re: Pylons and Rights to Objects...
I use a metaclass to set a require attribute on all methods of a class
that I define in a dictionary (PermissionIndex)
PermissionIndex = {
,'setatime': ['time']
,'setctime': ['time']
,'setmtime': ['time']
,'getsize': ['visible','read']
,'getcwd': ['visible','read']
,'listdir': ['visible','read']
,'rmdir':['visible','read','write']
,'remove': ['visible','read','write']
,'unlink': ['visible','read','write']
,'stat': ['visible','read']
,'chown':['perm']
,'chgrp':['perm']
,'set_group_perms': ['perm']
,'write_lock': ['wlock']
,'read_lock': ['rlock']
,'incr_version':['rlock',wlock','version']
class ACLRequirementDecorator(type):
'''
utility metaclass for setting the storage method acl requirements
from a dictionary.
'''
def __init__(cls, name, bases, dict):
super(ACLRequirementDecorator, cls).__init__(name, bases,
dict)
for k,v in dict.items():
if type(v) == type(lambda x:x):
if k in PermissionIndex.keys():
setattr(v,'require',PermissionIndex[k])
else:
setattr(v,'require',[])
class BaseStorage:
__metaclass__ = ACLRequirementDecorator
def __init__(self):
pass
.
I really like the way this separates the authorizer, the object doing
the work, and the storage of access control requirements.
I have several apps where I have to hook into ldap for
somethings,mysql for others, etc ... and this approach has worked well
for me.
Credits: The inspiration for that metaclass comes from somewhere I
can't recall now. Metaclasses still make me a little dizzy.
I use this with pylons but also in several other contexts.
Have a great day!
Kai

Webhelpers' h.link_to(_remote) escapes my URL :(
Dear list... I have created a URL using information from Routes using h.url_for(). Example: /start/page?page_nr=1called=back Now I want to create a link to this URL with h.link_to. What I get is: a href=/start/page?page_nr=1amp;called=backfoo/a Apparently '' is escaped to 'amp;' which is what I obviously don't want. Of course in the case of h.link_to I could just create the a href=... link myself. But my actual code uses h.link_to_remote which is a bit more complicated and I'd like to use the webhelpers for it. I looked into the Webhelpers sources and saw that the URL is not escaped if it's callable(). What does that mean? And what would be the correct way to just pass the URL through?

If you do self.variable = foo, you're shadowing the class variable. By the way, naturally, watch out for race conditions. Another option is to use the queue module and have the worker thread push messages onto the queue, and the controller can read messages from the queue. I tend to prefer message queues over explicit lock management.

Watch out for Paste because I think Ian put in some code to watch for runaway threads--it's probably fine. Use a timer and AJAX to have the Web page poll the server to see if the work is done. (You could use Comet, but polling is probably fine. Ignore this statement if you don't know what I'm talking about.) In the best case, you can use a progress bar on the page. Just work your way through it; I'm sure you'll be fine. Any recommendations on passing status between the worker thread and the controller when it's polling? I tried just using class variables, but they don't seem to get updated between the threads... How were you updating the class variable? ClassName.variable = foo? If you do self.variable = foo, you're shadowing the class variable. By the way, naturally, watch out for race conditions. Another option is to use the queue module and have the worker thread push messages onto the queue, and the controller can read messages from the queue. I tend to prefer message queues over explicit lock management. I've found this threadpool implementation useful for a similar task: http://tinyurl.com/yw6xc9 Alberto --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Spawning a worker thread from the controller?
Yeah, I was doing self.status = blah in the worker thread... The thread the controller is in doesn't seem to ever get this value... Using Class.status = blah doesn't seem to help much either... thx m On Fri, May 04, 2007 at 05:59:15PM -0700, Shannon -jj Behrens wrote: On 5/4/07, Matt Billenstein [EMAIL PROTECTED] wrote: On Fri, May 04, 2007 at 05:27:42PM -0700, Shannon -jj Behrens wrote: On 5/4/07, Matt [EMAIL PROTECTED] wrote: Hi, I have a pylons app which I want to spawn a long-running process from.

Re: Spawning a worker thread from the controller?
BTW, I'll add that I can do this in a simple standalone python script, spawn a thread and have both that thread and the main thread stuff data into a list or something... thx m On Fri, May 04, 2007 at 06:17:29PM -0700, Matt Billenstein wrote: Yeah, I was doing self.status = blah in the worker thread...
