Time difference in Django 1.11
I want my code to do two things:
Get datefield to give days only.
Get the difference btwn a depature_date and now.
Then this should be posted as:
2 days remaining to book.
I have been researching without any luck. Please help.
Models.py
from datetime import datetime; datetime.date; datetime.today;
datetime.now
class JoinedSafaris(models.Model):
package=models.ForeignKey(Packages)
Location=models.CharField(max_length=15, default="location")
date_of_depature=models.DateField(default=datetime.today)
today=models.DateField(default=datetime.now)
PS. When i use datetime.date or datetime.day in the fields, I get an error like this:
ValueError: Cannot serialize: <attribute 'day' of 'datetime.date' objects>
There are some values Django cannot serialize into migration files.
python django

The datetime.now function returns the current datetime.
If you want to save the creation date of an instance, add the auto_now_add attribute to your model.
class JoinedSafaris(models.Model):
package=models.ForeignKey(Packages)
Location=models.CharField(max_length=15, default="location")
date_of_depature=models.DateField(default=datetime.today)
today=models.DateField(auto_now_add=True)
