Question

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.
