Hi all,
I need your help on this.
Suddenly this weekend my templates on my Win XP box started breaking
with the error message:
TemplateSyntaxError at /vr/isi/items/
Caught an exception while rendering: invalid literal for int() with
base 10: ''
The template line causing the problem is:
<th> {{ flt_cy_average|floatformat }} </th>
If I check the value of flt_cy_average it is:
'flt_cy_average': 1.2436554207945787
If I hardcode the variable to a string with a comma delimiter it
passes without error:
flt_cy_average = '1,24'
I'm running the code on Windows XP, Swedish version and the same code
is working on an Ubuntu server without any problems. Is the problem
that the template engine is picking up my Swedish locale and how do I
change this.
I'm running Django revision 9526 and mod_python through Apache 2.2.
I've set:
USE_I18N = False
and tried:
import locale
locale.setlocale(locale.LC_ALL,'C')
but it doesn't help.
I've also tried to reverse to an old Django version, but it doesn't
help either.
Can anyone give me a hint on what's going on here? Is there a setting
where I can tell the template engine to expect decimal points for
floats?
Thanks for any help; traceback (on reverted Django version) below,
Ulf
