How can I Change type Of Django Calendar With Persian Calendar?

Question

I use Django 1.6.

When I have a field that have DateTimeField type, Django automatically use Django calendar.

But in Iran we use Persian Calendar (or Jalali Calendar or Farsi Calendar).

How can I change Django auto generation because it generate Persian calendar in page?

In other hand, I want change default calendar with Persian Calendar?

Answer 1

you can use django-jalali-date. Easy conversion of DateTimeFiled to JalaliDateTimeField within the admin site. only by inheritance a class!

settings.py

INSTALLED_APPS = [
    ...
    'jalali_date',
    ...
]

views.py

from jalali_date import datetime2jalali, date2jalali

def my_view(request):
     jalali_join = datetime2jalali(request.user.date_joined).strftime('%y/%m/%d _ %H:%M:%S')

template.html

{% load jalali_tags %}

<p>{{ request.user.date_joined|to_jalali:'%y/%m/%d _ %H:%M:%S' }}</p>

admin.py

from django.contrib import admin
from jalali_date.admin import ModelAdminJalaliMixin, StackedInlineJalaliMixin, TabularInlineJalaliMixin  

class MyInlines1(TabularInlineJalaliMixin, admin.TabularInline):
    model = SecendModel

class MyInlines2(StackedInlineJalaliMixin, admin.StackedInline):
    model = ThirdModel

@admin.register(FirstModel)
class FirstModelAdmin(ModelAdminJalaliMixin, admin.ModelAdmin):
    inlines = (MyInlines1, MyInlines2, )
    readonly_fields = ('some_fields', 'date_field',)

Just to add to the accepted answer, the Jalali DateField, with its appropriate date picker can also be implemented without the use of any custom widget.

First you must specify your DateField to accept its input in the Jalali format. This can be achieved through this custom model field :

from django_jalali.db import models as jmodels

class Order(models.Model):
delivery_date =  jmodels.jDateTimeField(verbose_name='تاریخ تحویل')

Now, for displaying the date picker to the user, you can use any desired javascript date picker that suits your needs, something like This Bootstrap Datepicker.
Assuming the field is going to be displayed as part of a model form, you can specify the HTML id or class of the widget responsible for rendering it:

class Order(forms.ModelForm):

class Meta:
    model = Order
    widgets = {
        'delivery_date': forms.DateInput(attrs={'id':'datepicker'}),
    }

Finally in your template, you only need to initialize the date picker:

    <script>
    $(document).ready(function() {
        $("#datepicker").datepicker({
            minDate: 2,
            maxDate: "+10D",
            isRTL: true
        });

    });
   </script>

Here is how it would look like in the end:

Answer 3

You will likely have to implement your own custom widget - I do not think Django provides a Persian calendar widget at this point in time.

There is an available code snippet for a Persian DateTime widget that I was able to locate, but have not yet tested. If it is not a perfect fit, then hopefully it will aid you in writing your own solution.

Answer 4

If you just need Persian DateField (for example for birthday), this tiny code will do it

YEAR_CHOICES = range(1377, 1300, -1)
MONTH_CHOICES = {1: 'فروردین',2: 'اردیبهشت',3: 'خرداد',4: 'تیر',5: 'مرداد',6: 'شهریور',7: 'مهر',8: 'آبان',9: 'آذر',10: 'دی',11: 'بهمن',12: 'اسفند'}

class ProfileUpdate(forms.ModelForm):
    class Meta:
        model = Profile
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        super(ProfileUpdate, self).__init__(*args, **kwargs)
        self.fields['birthday'] = forms.DateField(required=False, widget=extras.SelectDateWidget(empty_label=['سال', 'ماه', 'روز'], years=YEAR_CHOICES, months=MONTH_CHOICES))
