[Django]-How to disable formatting for FloatField in template for Django

You can now force the value to be printed without localization.

{% load l10n %}

{{ value|unlocalize }}

Taken from https://docs.djangoproject.com/en/2.2/topics/i18n/formatting/#std:templatefilter-unlocalize

I have a problem rendering lat and lng values.
My solution was:

{{ value|safe }}

You need to create a custom template filter.

from django.template import Library
from django.utils.numberformat import format

register = Library()

@register.filter
def floatdot(value, decimal_pos=4):
    return format(value, ".", decimal_pos)

floatdot.is_safe = True

Usage:

{{ float_var|floatdot }} or {{ float_var|floatdot:2 }}

You could use a custom formats.py (see “Creating custom format files” in the Django docs) and define THOUSAND_SEPARATOR and DECIMAL_SEPARATOR

THOUSAND_SEPARATOR = ''
DECIMAL_SEPARATOR = '.'

This is a global setting, so it will affect all floats displayed on your site. And you’ll have to turn on localization (USE_L10N in your settings.py).

If you have control over the template, you could simply remove the floatformat filter.

edit: I’m not sure, but perhaps you are a victim of this Django bug: #13617. Try to turn off localization support in your settings.py and see if the erroneous commas disappear:

USE_L10N = False

If that is the case, have a look at the various workarounds mentioned in the bugreport (the simplest being to turn localization off if you don’t need it anyway).

I’ve got the same issue, and as piquadrat says, it’s an annoying bug related to localization support. Changing USE_L10N = True to False solve this, it is suppposed to be fix in Django 1.3.

When print some variable for javascrip, its better to jsonify it. Write a jsonify template tag then use

{{value|jsonify}}

Template tags

from django.core.serializers import serialize
from django.db.models.query import QuerySet
import json
from django.template import Library

register = Library()

def jsonify(object):
    if isinstance(object, QuerySet):
        return serialize('json', object)
    return json.dumps(object)

register.filter('jsonify', jsonify)
