Closed last year.
I have created a django app and deployed it in Heroku.
The web app works fine and the user registration and login works too.
But when I open the django admin site it doesn't show the latest registered account. I have asked a few people to test my system so surely, there will be a few new accounts but the only accounts there were the ones I tested with a dummy account before deploying in heroku.
This is my admin.py

How to I solve this issue?

Why getting settings.DATABASES is improperly configured. Please supply the ENGINE value.?

I have not written so much line just created a new database in setting.py and routers file in django project.
After this run following command in shell and every this goes well and a new file with name auth_db.db.sqlite3 create.
python manage.py migrate --database=auth_db
and
C:\Users\Admin\Desktop\project\assignment>python manage.py createsuperuser --database=auth_db
Username (leave blank to use 'admin'): admin
Email address: admin#gmail.com
Password:
Password (again):
The password is too similar to the username.
This password is too short. It must contain at least 8 characters.
This password is too common.
Bypass password validation and create user anyway? [y/N]: y
Superuser created successfully.

Django admin site is not showing default permissions of models

My Django admin site does not show any default permissions of any models. Actually, I checked the database and I can't find any model permission in the auth_permissions table.
I've already run python manage.py makemigrations and python manage.py migrate. I also tried deleting the database and migration files and run two above command again but doesn't work. I've already registered my models in admin.py.
Any other solutions I can try ?

In your admin.py you are importing all of your models as from .Model import *. Python is a case-sensitive programming language if you have not manipulated your models.py file as Models.py.
I suppose from .models import * will do the trick

The above solution solves the problem. However, my Models is actually a folder, I've been trying to divide the models into different files which are stored in that folder. So for those who have the same idea, just simply change the folder's name into models and you're good to go :v

first thank you for your answers and support in this question.
I agree with Sanchit and shreesh katti answers, we can use mongoclient and mongoengine to connect with MongoDB, both works good.
I have found one another way, there is an open source project djongo and I am using djongo to connect with MongoDB database. The main benefit of djongo is that it lets you use everything that django provides ( eg models.Model).
here is link of djongo GitHub page https://github.com/nesdis/djongo
this is settings that we need to use djongo
settings.py
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'MyDB',
}
}

Django works well with Relational databases like PostGreSQL, MySQL. Every django settings needs to have a Database configuration defined with 'default' configurations it also needs database respective engine like psycopg2 for PostGreSQL, mysqlclient for MySQL - if you have multiple database configurations then you need to use database router check here for reference. In case of MongoDB - its a NoSql database which Django officially doesn't support if you really need to use MongoDB create a mongoengine configuration in views and you can define mongo credentials in settings.py

Using pymongo in django views:
client = pymongo.MongoClient(MONGO_URI)
mongodb = client[MONGO_DB_NAME]
...
class MongoClassView(View):
def post(request):
...
mapped_data = {'name': 'John'}
mongodb.get_collection('mycollection').insert(mapped_data)
return JsonResponse({})
hope this helps

You can try these steps to connect your django 2.0 or more with MongoDB database:
1) Install mongoengine for django 2.0
pip install -e git+https://github.com/MongoEngine/django-mongoengine.git#egg=django-mongoengine
2)Add these in your settings file:
from mongoengine import *
'django_mongoengine', // Add this line to installed app
MONGODB_DATABASES = {
"default": {
"name": '<db_name>',
"host": 'localhost',
"password": '',
"username": '',
"tz_aware": True, # if you using timezones in django (USE_TZ = True)
},
}
You can find the details for querying the database here

Use mongoengine and djongo to connect.
Make the following changes in your settings.py file
mongoengine.connect(
db=config.main_db,
host=config.host,
#username=config.username_admin,
#password=config.password_admin,
#authentication_source=config.authSource_admin,
#authentication_mechanism=config.authenticationMechanisms)
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': config.main_db,
# 'USER': config.username_admin,
# 'PASSWORD': config.password_admin,
# 'HOST': config.host,
# 'PORT': config.port,
}
}

use djongo to connect to your mongodb:
use these versions on your venv (if you want to use virtual env):
dataclasses==0.1
Django==2.0
djongo==1.2.30
pymongo==3.2
pytz==2018.5
sqlparse==0.2.3
and follow this: Connect MongoDB to Django (using djongo)
