如何更改特定 Django 管理员 Model 中的时区？

Question

I want to change the timezone just within the one Particular Model in Django admin, how can I do that?

As Django saves time in the database in UTC, what I want is to display the value in a particular timezone, just for one model. Not for the whole project.

For example I have a model:

class Student(models.Models)
    created_at = models.DateTimeField()    

When I open Django Admin for this model, I want to see the time in a particular timezone (let's say ETC) but let the Django save time in UTC.

Answer 1

so I have figured out the solution: To accomplish what I wanted to accomplish I had to made changes in the ModelAdmin class.

    class StudentAdmin(Admin.ModelAdmin):
        list_display = [..., "created_at_etc", ...]
        def add_view(self, request, form_url='', extra_context=None):
            timezone.activate("US/Eastern")
            return super(ActivityAdmin, self).add_view(
                request,
                form_url,
                extra_context
            )

        def change_view(self, request, object_id, form_url='', extra_context=None):
            timezone.activate("US/Eastern")
            return super(ActivityAdmin, self).change_view(
                request,
                object_id,
                form_url,
                extra_context
          )

        def get_time(self, time):
            import pytz
            fmt = '%Y-%m-%d %H:%M:%S %Z'
            tz = pytz.timezone("US/Eastern")
            dt = time.astimezone(tz)
            return dt.strftime(fmt)

        def created_at_etc(self, student):
            return self.get_time(student.created_at)

        created_at_etc.short_description = "Created At"
    

You can activate a particular timezone in django admin by using

from django.utils import timezone
timezone.activate("US/Eastern")

With this you can change the timezone within a context you want to. As I am doing the same in the add_view , change_view .

First I overrided the add_view method that will let us create the Student object in the particular timezone. Second I Overrided the change_view so that we can edit the already existing Student in the particular timezone. Third I created created_at_etc it will display the date with respect to the particular timezone.
