Get date from a Django DateTimeField

Question

I would like to request some assistance regarding this matter

I am learning django and trying out some codes but I hit a brick wall at trying to get the date only from a model's DateTimeField

here's the code that I am working on:

class APPLICANT_DATA(models.Model):     SCHEDULED_AT = models.DateTimeField(null=True, blank=True)   def somefunction():     app_data = APPLICANT_DATA.objects.all()     for item in app_data:         the_date = str(item.SCHEDULED_AT.strftime("%B-%d-%Y")) + ", " + the _date 

And I am getting ('NoneType' object has no attribute 'strftime') even though my model contains 3 records that all have date and time

What am I doing wrong? any advice for a newbie? many thanks.

Answer 1

DateTimeField becomes a datetime.datetime object in Python

If you need a date object to manipulate later on, you could pull the datetime.date object directly from your DateTimeField(), using datetime.datetime.date() like below:

class ApplicantData(models.Model):     scheduled_at = models.DateTimeField(null=True, blank=True)  date = application_data.scheduled_at.date() 

This works because Django will translate the DateTimeField into the Python type datetime.datetime, upon which we have called date().

Format the datetime.date like you wish

Then from that, you get a datetime.date object, that you can format like you wish, using datetime.date.strftime().

If you don't need a date object, you can also use strftime on your datetime.datetime object too, no problems with that. Except that your had a None field in your object.

Dealing with NULL/None fields

If you want to allow for NULL values in scheduled_at you can do:

if application_data.scheduled_at is not None:       date = application_data.scheduled_at.date()
