ProgrammingError at /admin/ Table 'django_session' doesn't exist python

I got this following error while running django project "ProgrammingError at /admin/ Table 'django_session' doesn't exist".

SOLUTION:

This error you will get, when you're not migrated the django model.

CODE:

import datetime

from django.db import models

import os

from django.db import models



def getFileName(request,filename):

    now_time=datetime.datetime.now().strftime("%Y%m%d%H:%M:%S")

    new_filename="%s%s"%(now_time,filename)

    return os.path.join('uploads/', new_filename)



class Category(models.Model):

    name=models.CharField(max_length=150,null=False,blank=False)

    image=models.ImageField(upload_to=getFileName,null=True,blank=True)

    description=models.TextField(max_length=500,null=False,blank=False)

    status=models.BooleanField(default=False,help_text="0-Show,1-Hidden")

    created_at=models.DateTimeField(auto_now_add=True)



    def __str__(self):

        return self.name

python manage.py makemigrations

python manage.py migrate

python manage.py createsuperuser

SOLUTION:

pip install matplotlib
