Error during template rendering - error page helps only a little

[Pietro Bernardi]

Hi,

the case:

NoReverseMatch error
Reverse for '<smth>' with arguments '<smth else>' not found.
Error during template rendering
In template <path_to_template>/base.html, error at line 0

I don't know where the error is, I must discover it (and correct it ;), but sure it isn't at line 0 of base.html template.
(I know, it's a point where the error blowed up)

Regards

Can you please give a sample project that reproduces the issue?

[Pietro Bernardi]

I can, of course, it's my duty, I think. But not right now - project deadline, you sure know it ;) Later. Hope I'll be able to do a minimum working example soon.

Could be related to #29446

Yes, it's related, but my main displeasure was this:

In template <path_to_template>/base.html, error at line 0

I'm sure no one of my templates has line 0, each one starts with line 1

I can explain MWE - it happens whenever I've error in url(..., name='smth') argoment. Better debug help should be point to place in template (but real one), where involved line is, line with corresponding {% url 'appname:viewsprocname' %}, not to line 0 of base.html (which BTW is nonexistent, file starts with line 1)

Just my 5 cents
