DateField and TimeField don't come out after adding to model class
I'm quite new to Python and Django. I'm setting up a new model class and I'm able to add appointments on the admin page, but here's the strange thing:
I used to have a DateTimeFiled, which I changed to a separate DateField and a TimeField. But now I see neither my DateField nor my TimeField. Why is that, I don't understand it. I've done the migration, everything looks right.
This is my model class:
class Appointment(models.Model):
patient = models.ForeignKey(User, related_name="appointment_patient", on_delete=False)
date = models.DateField(auto_now=True)
start_time = models.TimeField(auto_now=True)
duration = models.DurationField(default=timedelta(minutes=30))
Before I made this change every property came out right, but now this happens:

auto_now automatically updated with timezone.now() whenever the model object is saved also its not editable. So its not necessary to display them in the template. That is why adminsite omits this field or does not show it. Please see the documentation for more details. If you want to display this field then add it readonly_fields. For example:
class YourModelAdmin(admin.ModelAdmin):
readonly_fields=('start_time',)
Update
If you want to add default value to DateField, try like this:
import datetime
# in models
state_date = models.DateField(default=datetime.date.today) # without parenthesis

Oh I see, that makes sense. I tried it before with a default value but ran into issues, then I tried it like that. Anyway it should not be readonly. I've retried it with a default value but I do not get it how to set it. There are multiple explanations around which don't work (they might be Python 2).I've seen this line in the documentation, which I doesn't work without the import part:For DateField: default=date.today - from datetime.date.today(). I don't understand the import part. That's not the import syntax?!? What's the import statement so thatdate.todaywould work?

this Python syntax is killing me! Neither works, notdefault=date.todaynordefault=datetime.date.today. In the first case PyCharm already complains, in the latter case the migration fails:AttributeError: 'method_descriptor' object has no attribute 'today'
