#19280 closed Cleanup/optimization (fixed)

Detect broken {% url %} syntax

Description

In 1.5 the url syntax change will likely result in users getting this template error:

NoReverseMatch: Reverse for '' with arguments '()' and keyword arguments '{}' not found.

I think we could catch the error in the url tag, and check if we are trying to reverse . If so, add in a hint:

NoReverseMatch: Reverse for '' with arguments '()' and keyword arguments '{}' not found. Note: url syntax has changed in Django 1.5, see [insert good resource here]

This could save some time for those upgrading to Django 1.5.

I guess we should capitalize "url" but other than that this looks good to me.

Change exception type to reduce confusion.

TemplateSyntaxError is expected at compile time, not at run time.
