Display the signup time of the User ( member since )

I am building a Blog WebApp and I am trying to implement a Feature.

What i am trying to do :-

I am trying to display the Date or Time of user's signup (Like stack overflow does (member since 2 months))

models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE,default='',unique=True)
    full_name = models.CharField(max_length=100,default='')
    time = models.DateTimeField(auto_now_add=True)

    @property
    def age(self):
        current_datetime = datetime.now(tz=datetime.timezone.utc)
        return (current_datetime - self.time).days

template.html

{{ request.user.profile.time }}

You can use property in models. By using this you will be able to fetch age everytime you query Profile model

from datetime import datetime, timezone

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, default='', unique=True)
    full_name = models.CharField(max_length=100, default='')
    time = models.DateTimeField(auto_now_add=True)

    @property
    def age(self):
        current_datetime = datetime.now()
        #current_datetime = datetime.now(timezone.utc)  for tz aware datetimes
        return (current_datetime - self.time).days

You could use django-model-utils. To be more specific create model that inherit TimeStampedModel.

To render "since " you could use django.contrib.humanize.templatetags.humanize.

To use directly in code:

humanize.naturaltime(datetime.datetime.now() - yourmodelinstance.created)

To use in template:

{% load humanize %}

{{ yourmodelinstance.created | naturaltime }}

Your example would look like:

import datetime
from django.contrib.humanize.templatetags import humanize
from model_utils.models import TimeStampedModel

class Profile(TimeStampedModel):
    user = models.OneToOneField(User, on_delete=models.CASCADE, default='', unique=True)
    full_name = models.CharField(max_length=100, default='')

    @property
    def age(self):
        return humanize.naturaltime(datetime.datetime.now() - self.created)

To get rid of alot of milisecond You could replace age property return value with:

@property
def age(self):
    return humanize.naturaltime(datetime.datetime.now().replace(microsecond=0) - self.created.replace(microsecond=0)
