How to compare dates in django-CodePudding

I am working on a task manager project, user can define the "ending date" of the task, I would like to change the front end code of a task that isn't completed before the "endind_date".I tried playing around in models.py but i get back this error: "can't compare datetime.datetime to datetime.date"

models.py:
class Task(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True)
    title = models.CharField(max_length=200)
    description = models.TextField(max_length=200, null=True, blank=True)
    complete = models.BooleanField(default=False)
    importance = models.ForeignKey(Importance, null=True, blank=False, on_delete=models.CASCADE)
    creation_date = models.DateField(default=timezone.now)
    ending_date = models.DateField(null=True, blank=False)

    def __str__(self):
        return self.title

    def is_end_date(self):
        if datetime.now() > self.ending_date:
            if not self.complete:
                return True
            else:
                pass
        else:
            pass

html(only included related code to the problem):
 {% if task.is_end_date %}
  #code
{% else %}
 #code

CodePudding user response：

You should convert the datetime object to a date, by calling .date() on it:

from django.utils.timezone import now

class Task(models.Model):
    # …
    
    def is_end_date(self):
        return now().date() > self.ending_date and not self.complete

Note: It is normally better to make use of the settings.AUTH_USER_MODEL [Django-doc] to refer to the user model, than to use the User model [Django-doc] directly. For more information you can see the referencing the User model section of the documentation.

CodePudding user response：

You can use date.today() or datetime.now().date() as

Using date.today() as

from datetime import date

def is_end_date(self):
    if date.today() > self.ending_date:
        if not self.complete:
            return True
        else:
            pass
    else:
        pass

Or datetime.now().date()

from datetime import datetime

def is_end_date(self):
    if datetime.now().date() > self.ending_date:
        if not self.complete:
            return True
        else:
            pass
    else:
        pass
