Django Admin: Using a custom widget for only one model field

Question

I have a DateTimeField field in my model. I wanted to display it as a checkbox widget in the Django admin site. To do this, I created a custom form widget. However, I do not

Answer 1

After digging into the admin, model field and form field code, I believe the only way to carry out what I want is by creating a custom model field:

models.py

from django.db import models
from widgets import ApproveStopWidget

class ApproveStopModelField(models.DateTimeField):
    pass

class Stop(models.model):
    # Other fields
    approve_ts = ApproveStopModelField('Approve place', null=True, blank=True)

admin.py

from widgets import ApproveStopWidget
from models import ApproveStopModelField

class StopAdmin(admin.ModelAdmin):
    formfield_overrides = {
        ApproveStopModelField: {'widget': ApproveStopWidget }
    }

It gets the job done.

For the time being, I'll leave the question unanswered because I have the habit of missing the obvious. Perhaps some Django smartypants has a better solution.
