问题
I'm trying to migrate an old django application to django 1.5, There are 745 urls in different html files as this way:
{% url url_name %}
If I'm not wrong, this was deprecated and can't be used anymore from django 1.5 (as said here), and I have to transform all of them into:
{% url 'url_name' %}
Any idea to do this without going crazy? Maybe, some kind of script, I dont know... I can't imagine a way to do it with replace in path.
I'm probably missing something obvious.

NOTE: This command is destructive. Use version control or backup your templates directory before running it.
You can use sed. From your template directory (or directories) run
sed -i -r -e "s#\{% url ([a-zA-Z0-9_.:-]+)#\{% url '\1'#g" *
The expression matches {% url [view name], so arguments provided to the url template tag will be unaffected/unchanged.
To run it recursively,
find . -type f -print0 | xargs -0 sed -i -r -e "s#\{% url ([a-zA-Z0-9_.:-]+)#\{% url '\1'#g"
This sed command assumes your view names only contain alphanumerics, colons, dashes, periods and underscores - no other special characters. Now supports namespaced views.
Tested against the tags in this Django 1.4 url template tag Gist

There is also a snippet with a solution in python at http://djangosnippets.org/snippets/2905/
Just a warning, the find . -type f -print0 will find files that are "hidden" like files in your .git/ or .hg/ directories and may corrupt your repository or other binary files.
If you use the usual convention in django with your template files ending in .html, you can search more cautiously with:
find . -iname '*.html' -type f -print > file.list
examine file.list first to check which files are being modified before putting it together with the sed command
