Setting 'locale' dynamically

[Bloodmallet]

Describe the problem My users can have different locales. Therefore I need to set the locale of each widget dynamically on form creation. I couldn't find a solution to this in the documentation. If possible I'd like to get some input on my approach.

Setup Information (please complete the following information):

• OS: Windows 10
• Browser chrome, firefox
• Python version 3.7
• Django version 2.1
• Bootstrap version 4

[x] I have followed the configuration instructions and checked out the common error troubleshooting page.

Approach

forms.py

from django import forms
from bootstrap_datepicker_plus import DatePickerInput
from example.models import ExampleModel


class ExampleForm(forms.ModelForm):
    class Meta:
        model = ExampleModel
        fields = [
            'date',
        ]
        widgets = {
            'date': DatePickerInput(),
        }

    def __init__(self, *args, request=None, **kwargs):
        super().__init__(*args, **kwargs)
        if request:
            self.fields['date'].widget = DatePickerInput(options={'locale': request.LANGUAGE_CODE})

views.py

[...]
    form = ExampleForm(request=request)

Does LANGUAGE_CODE match with available locales?

At least in my case it does...maybe only for now.

Any update on this issue? I am trying to localize all date and times in my Django application by setting USE_l10N to True in my configuration. The date and times are formatted according to the locale requested by the browser. So for example a Dutch user sees a date like '25 mei 2020' and an English user would see 'May 25, 2020'.

I can get the Bootstrap datepicker to show Dutch names for months and days if I add options={'locale': 'nl'} in my form. Is it possible to let Bootstrap datepicker use the language that was requested by the user? Is'nt this what localized_fields = '__all__' is supposed to achieve?

This is what my form looks like:

class DeliveryForm(forms.ModelForm):
    class Meta:
        model = Delivery
        fields = ['delivered_at', 'supplier', 'quantity']
        localized_fields = '__all__'
        widgets = {
            'delivered_at': DateTimePickerInput()
        }

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.form_method = 'post'
        self.helper.add_input(Submit('submit', 'Save'))
        self.helper.layout = Layout(
            Row(
                Div('delivered_at', 'supplier','quantity', css_class='col-3')
            )
        )

class DatePickerForm(forms.Form):
    date = forms.DateField(widget=DatePickerInput())

    def __init__(self,*args,**kwargs):
        django_language=kwargs.pop('django_language')
        super(DatePickerForm,self).__init__(*args,**kwargs)
        self.fields['date']=forms.DateField(widget=DatePickerInput(options={'locale':django_language}))
