I am very new to Django. I have created a sample project with Python v3.6 and Django V2.1. Initially, I have was using default sqlite3 database but now we have planned to change that into Mysql. For that, I have installed all the necessary plugin. On the other hand, I didn't create any table with sqlite3 except admin.
It is working fine if it was in default database when I change that into MySQL I am getting error which I can't resolve for a week :-(

This is my settings.py file in django
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'database_name',
'USER': 'postgres',
'PASSWORD': '******',
'HOST': 'localhost',
'PORT': '5434',
}
}
Hi, I figured it out. Really stupid mistake. I add two of the Database= {} configuration twice, once at the top of the file and once i the bottom and for got to delete it lol.
This issue is generated for lack of permission.You should give the permission in pg_hba file.
Log into your db user and then play the command psql. The sequensial coammnd is given bellow.
sudo su - postgres
psql
show hba_file;
In my case the output is /var/lib/postgresql/data/pg_hba.conf. Rember this location
\q
ctrl + d # for loging out from postgres user
sudo vim /var/lib/postgresql/data/pg_hba.conf #you can use your prefer text editor
You need to change the file as shown bellow. Just change all method to trust.
Firstly, I'm on Windows 10.
I just started learning Django. I did the tutorials that are with the Django documentation. I need to program an app that uses a PostgreSQL database. This is for a test following up a job interview, so I don't want to mess this up.
When I run the command "python manage.py runserver", I run into the following error :

Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
The Django documentation says that I need to install psycopg2. Which I did using the command "pip install psycopg2". I configured settings.py in my Django project in order to use a PostgreSQL database :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'myDataBase',
'USER': 'myDataBaseUser',
'PASSWORD': 'password',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
Changing 'ENGINE': 'django.db.backends.postgresql' to 'ENGINE': 'django.db.backends.postgresql_psycopg2' gives me the same error.
I also tried to change '127.0.0.1' to 'localhost' and it still doesn't work.
(The different topics I've seen talk about a postgresql.conf file, but I can't seem to find it anywhere, if it can even solve anything anyway.)
What am I doing wrong?
Edit
After installing PostgreSQL 9.6, creating myDataBase, creating a role myDataBaseUser and granting the privileges to that role, I now get that error:

It seems like you dont have postgres database installed locally. Download it from here
Then going into console you need to create database by create database myDataBase;
create role by create role myDataBaseUser with password 'password'. Grant privileges to the role by
grant all privileges on database "myDataBase" to myDataBaseUser.
Then you will
be able to connect.
In fact, I learn the django from the website:https://docs.djangoproject.com/zh-hans/2.1/intro/tutorial02/
The next is my settting.py

}
}
mysql :

I want to know how to solve this problem,or I don't know what's the problem?
Thank you very much!
I think DATABASES is right,
I want to connect mysql to django program named mysite, but I run 'python manage.py migrate':

django.db.utils.OperationalError: (2006, <NULL>)
Maybe it's because django can't support the new password encryption of mysql. You should try changing it.
You can do this from the mysql command line client:
I got the same OperationalError: (2006, <NULL>) when using python to connect to MySQL Server on Windows. It seems like the error has something to do with the new authentication method in MySQL 8. I reconfigured the MySQL server from using the recommended authentication method to "Use Legacy Authentication Method" and the error goes away.
I'm setting up django on amazon web and I'm getting an issue connecting to the database. I created the database and checked to see it exists:

and the user also exists

SOLVED: Issue was using USERNAME, not USER.
I am able to connect to the RDS instance from both MySQL Workbench and the mysql CLI command, so it is not the credentials that are the issue. I am trying to run python manage.py migrate but I get the following output:

raise exc
django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'xxx.xxx.us-west-2.rds.amazonaws.com' ([Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond)")
I've set the AWS Security Group and VPC Security Group with
All traffic | All | All | 0.0.0.0/0
I have the following in my settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'playercomp',
'USERNAME': 'xxx',
'PASSWORD': 'xxx',
'HOST': 'xxx.xxx.us-west-2.rds.amazonaws.com',
'PORT': '3306',
}
}
And this at the beginning of my manage.py
#!/usr/bin/env python
try:
import pymysql
pymysql.install_as_MySQLdb()
except ImportError:
print "Failed to import pymysql"
I'm just very confused since I can connect through mysql CLI, MySQL Workbench, and even through short python scripts like below.
connection = pymysql.connect(host='xxx.xx.us-west-2.rds.amazonaws.com',
user='xxx',
password='xxx',
db='playercomp',
charset='utf8mb4',
cursorclass=pymysql.cursors.DictCursor)
Solution was to change USERNAME to USER.
