In Django 1.5 url tags require you to pass in the name of the url as a string.
So where you used to be able to do this {% url home_page %} you now have to do this {% url 'home_page' %}
Upgrading an old project can be a pain, so here is a snippet for a py file that will update all your url tags. Just put it in a py file in your root directory and execute it.
The error you get otherwise is: 'url' requires a non-empty first argument. The syntax changed in Django 1.5, see the docs.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | import os, re
app_path = os.path.split(os.path.split(__file__)[0])[0]
PROJECT_ROOT = os.path.abspath(app_path)
def update_path(directory):
"Update {% url to include ''"
for path, dirs, files in os.walk(directory):
for fname in files:
if fname.endswith('.txt') or fname.endswith('.html'):
fpath = os.path.join(path, fname)
with open(fpath) as f:
s = f.read()
s = re.sub(r'{% url "(\w+)" ', r"{% url '\1' ", s)
s = re.sub(r'{% url (\w+) ', r"{% url '\1' ", s)
with open(fpath, "w") as f:
f.write(s)
for dir in dirs:
update_path(dir)
update_path(PROJECT_ROOT)
