How to authenticate User from mysql in django?

I want to implement login app. all the users information are in table named 'admin_users'. I am using mysql server by xampp.
when i am authenticating using user = authenticate(username=username,password=password)
On printing user I am getting None.
I am beginner in django and I could not find out whats wrong.
If I am doing AdminUsers.objects.all() I can print all the table information.
models.py
class AdminUsers(models.Model):
username=models.CharField(max_length=50)
firstname=models.CharField(max_length=50)
department=models.CharField(max_length=50)
mail=models.CharField(max_length=50)
id=models.IntegerField(primary_key=True)
password=models.CharField(max_length=200)
class Meta:
db_table="admin_users"
view.py
def login(request):
if request.method == 'POST':
username = request.POST['username']
password = request.POST['password']
user = authenticate(username=username,password=password)
print(user)
return render(request,'AdminUsers/login.html')
my index.html contains simple forms with username and password.

Not sure what your goal is with the AdminUsers model. The default django user model has flags like is_staff and is_superuser that you can use to seperate users and their permissions with regards to what they can access on the app.
Check out the docs on the user model here

You need to insert this in your settings: AUTH_USER_MODEL = 'AppName.AdminUsers' (replace AppName with the name of the app containing AdminUsers).
Your custom User model should inherit from AbstractUser to be compatible with the authentication system (right now it will not work):
class AdminUsers(AbstractUser):
department=models.CharField(max_length=50)
class Meta:
db_table='admin_users'
Now AdminUsers will inherit fields of AbstractUser (username, email, password, is_staff, ...), read this for details.
If you have already done migrations, you need to delete migrations of the default User model.
Note also that you should name the model 'AdminUser' and not 'AdminUsers'.

Connect Mongodb with Django

I am trying to connect mongodb with django, but i am getting this error
ImproperlyConfigured: 'djongo' isn't an available database backend.
Try using 'django.db.backends.XXX', where XXX is one of:
'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
I have read posts but they are all old and not helping me. I have created mongodb database using studio 3T, name of database is NewDataBase user is gsc-30310 port is 27017 host is localhost
Versions I am using are:
python3
Django==2.1.1
mongoengine==0.15.3
pymongo==3.7.1
Here is my settings.py file, please tell me how to setup for new version of django and python 3. thanks

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)

Django ignores test database settings

I have an app deployed on pythonanywhere which runs fine. Problem is that when I want to run test django, my test database settings is completely ignored.
Each time I run test I get the following message.though.
Creating test database for alias 'default'...
Got an error creating the test database: (1044, "Access denied for user 'funnshopp'#'%' to database 'test_funnshopp$funn'")
Database name for the app is funnshopp$funn. It can be seen that django somehow always tries to create the test database by appending test_ to the database name. Never minding what I have in DATABASES settings
Below is my full settings file ( Test runs fine on my PC and I am using Django 2.0, though I started the project with Django 1.11)

This is a common and correct behavior. Django when testing will always try to create new database, and you should never try to test you application on your live/production database.
Your tests should be constructed in a way, where you create your objects and then test their behavior. You are using postgres, on heroku and mysql on development server. If you want to use this databases to test you app, you have to add django user to you postgres/mysql with rights to create and delete databases/tables.
You can also avoid this by adding this setting to your settings.py (this is what I like to do when I do not use any other extensions and sqlite3 database is just enough. I run my tests by typing python manage.py test
if any([arg in sys.argv for arg in ['jenkins', 'test']]):
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'mydatabase',
}
}

I think you should change how you format your settings.py, you must not put if conditions inside it but use different settings based on the environment you are working on!
I recommend you to read this tutorial.
When you have the proper layout you can change the database in the different settings file ;)!

I solved the problem by reorganizing my settings file according to the pattern suggested here Recommended Django Project Layout.
Now my test runs fine on pythonanywhere.
Btw, I created a gist here which deals with the problems of virtual environments and layouts and how to handle virtual environment variables.

As you know, when you are running tests, Django isolates the changes made to the database. That is why it tries to create a database which is denied by the DB engine. You can either:
Create a database, grant access to the user and use --keepdb to run the tests
Or grant access to the DB user to create a database. Something like:
ALTER USER username CREATEDB;

django on production 500 server error for User related Model in Admin

I have deployed my Django(1.10) site on google compute engine, everything was working fine, but suddenly one of my model throwing 500 Server Error in admin.
I have googled around but couldn't find any solution.
All other models are displaying properly in django admin except only one and that's TaggedArticles model.
Idon't have changed anything in my site, what's can be wrong? as it happens suddenly to my site.

This can be a mysql timezone issue. This is assuming that you have the required libraries from the error.
Check if the below value has been set in your /etc/mysql/my.cnf in [mysqld] section (after that tag). FI no, enter it and then reboot
`default-time-zone = 'UTC`'
Once you do this and it still doesnt work try flushing after doing the above.
mysql> flush tables;

Error migrating MySQL database into Django. Unexpected host name

I am trying to migrate a MySQL db into Django. I created a simple database when I followed a tutorial, but now I am trying to migrate my actual db into the project. I modified settings.py to look like this (changed the databases section):

My error:

Where the heck is it getting dev-backend.cluster as the database from?
My migrate command:
python manage.py makemigrations
python manage.py migrate

Check for settings downstream of that DATABASES assignment. A common pattern in Django projects is a layout like this:
# In settings.py, declare all the base values
DATABASES = { ... }
INSTALLED_APPS = [ ... ]
# Import other settings based on environment
if os.environ.get("environ") != "production":
from .devel import *
For better or worse this pattern or variations thereof are commonplace. You likely have an import under a conditional later in the file.

I also encountered the same problem.
if yyyy-backend.cluster-cwtxulgbsb88.us-east-1.rds.amazonaws.com is
correct?? can name resolve?
You might want to use its
IP address for connecting instead.
Because Usually the case when name resolving doesn't work on the host.
