(Fixed description formatting)

What were you doing to trigger this traceback? The loader_tags.py module definitely does have a variable named register in it, so there is something else going on here.

Can you run "svn status" and check that no files in your source tree are changed from the versions in trunk?

[melindia777@…]

Everything is in sync...

I didn't do nothing ! I swear ... not my fault ;)

Seriously, I updated with svn and then, this traceback.
Just began this project.

[Malcolm Tredinnick]

Then we have a problem, because I cannot replicate this at all. :-(

What checkout version are you using? Run "svn info" in, say, the root directory of your source and see what it says for "Revision". I really cannot think of anything we've done to cause this, though.

One thing to do is to try backing up a few revisions and see if you can work out where things start to go wrong. So if, for example, you are at revision 5319, go back to 5200 and see if the problem reoccurs (svn update -r 5200). If it doesn't happen then, move forwards halfway. Rinse, wash, repeat. If we at least know what checkin causes the problem, if might give us some clues.

We figure it out. Yé !
We used a symlink django-­>django.svn/django in our project folder. It was working until now. We did proper system install and it works...

Do you know if we can use the symlink trick ? It was handy!

Thanks for your very nice answer !

Hmm.. did you have another version of django installed? maybe in your site-packages library?

[Pashka R. <pashka.reznikov@…>]

I have 0.95 installed in the system but I want to use 0.96.... so I've setup .htaccess:

SetHandler python-program
PythonPath "['/webhomes/exclaim/public_html/kids2', '/webhomes/exclaim/public_html/kids2/..'] + sys.path"
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE settings
PythonDebug On

all works (​http://kids.dn.ua/info/project.html [ru]) except of / (​http://kids.dn.ua/) ... I've got the same error.....

has someone any idea about how can I fix this? Thnx

wbr Pashka R.

[Pashka R. <pashka.reznikov@…>]

....and.... I have symlink /webhomes/exclaim/public_html/kids2/django --> /path/to/django0.96...

Please don't use the Trac system for support requests. We have mailing lists for that.

I'm not sure that this isn't actually a bug. I believe it's been fixed in more recent versions, but I can produce a similar error in 1.6 very simply:

For the benefit of anyone else searching for this error message, the best workaround I've found is to import django.template.loader before django.template.loader_tags:
