[name='index']
signup [name='signup']
admin/
^media/(?P.*)$
The current path, signup.html, didn’t match any of these

This is used here do {....} while(ch!=?.?); what does ch!=?.? mean here can anybody please help with it.
It's a syntax error with both clang and gcc.
#JonathanLeffler is usually right and I think he nailed the root cause. I used to see this when text was being copied from Microsoft Word to the web (lack of transcode from a Windows code page to ascii/utf8?).

I think I saw something on using this to truncate test as a filter, but I've seen to no idea how to use it. Using as xx|do_trucate(20) gives the following:
TemplateAssertionError: no filter named 'do_truncate'
What is the correct usage?
Doh, from the spec I saw
do_trucate

But in reality, its just truncate

I'm trying to write a regex that can match both following lines:
http://ficsgames.org/cgi-bin/show.cgi?ID=364189186;action=save
http://www.ficsgames.org/cgi-bin/show.cgi?ID=364189186;action=save
I've got this:
http:\/\/(www)?ficsgames\.org\/cgi-bin\/show\.cgi\?ID=[0-9]+;action=save
but it doesn't seem to work - http://regex101.com/r/vB2cM3/1
You are missing a dot . inside of your optional group.
(www\.)?
You're missing a \. in your (www)?
You forgot the . after www. (which needs to be escaped)
I've updated your regex link here:

I have got this strange exception : the object exists in my database, get doesn't work but filter does...
(Pdb) p ProjectPhase.objects.get(slug='done-complete')
*** DoesNotExist: DoesNotExist('ProjectPhase matching query does not exist.',)
(Pdb) p ProjectPhase.objects.all().filter(slug='done-completed')
[<ProjectPhase: 8 - Done - Completed>]
Any hint ?
Both texts are different. First one is: done-complete and second one done-completed.
So,
ProjectPhase.objects.get(slug='done-completed')
Should work
