Django number_format not function - django

Question

I'm trying to use the intcomma to format my number in template, but it cannot work properly.
{%load humanize%}
{%blocktrans with val=myvalue|intcomma%}The number is {{val}}{%endblocktrans%}
After some searching, I found the django.utils.formats.number_format is not function. Hereunder is my testing:
corpweb#56944bf480d1:~$ ./manage.py shell
Python 3.4.4 (default, Feb 17 2016, 02:50:56)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import locale
>>> from django.utils.formats import number_format
>>> val=123456789
>>> number_format(val,force_grouping=True)
'123456789'
>>> locale.getlocale()
('en_US', 'UTF-8')
>>>
Is there have anything I setup wrong?

Answer 1

When rendering templates or using number_format outside of the Django app flow the translation module is not activated. Here are a few notes and instructions on how to turn on translation in custom management commands.
To make the shell example work we just need to activate the translation module as such:
(venv) $ ./manage.py shell
Python 3.6.4 (default, Mar 1 2018, 18:36:50)
>>> from django.utils.formats import number_format
>>> from django.utils import translation
>>> translation.activate('en-us')
>>> number_format(50000, force_grouping=True)
'50,000'
The key line above is: translation.activate('en-us')

Everything is ok with your setup I guess. Just set USE_L10N = True in your settings.py if it is set to False, as #Tim Schneider mentioned, and you better try it like this {{ val|intcomma }} as #Leonard2 mentioned and it must work. And also as it is mentioned here make sure:
To activate these filters, add 'django.contrib.humanize' to your INSTALLED_APPS setting.
