Try to connect my django project with MySQL using wamp server i am facing error
"Django.db.utils.NotsupportedError"
I am tried older version of django
To solve this error, but it seems also
Same error.
To connect Django to a MySQL database, you will need to install a MySQL database connector. The most common connector is mysql-connector-python, which you can install using pip:
pip install mysql-connector-python
Once the connector is installed, you will need to update your Django settings to use the connector and specify the connection parameters for your MySQL database. The settings will typically look like this:
DATABASES = {
'default': {
'ENGINE': 'mysql.connector.django',
'NAME': 'mydatabase',
'USER': 'myuser',
'PASSWORD': 'mypassword',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}
You will need to replace the NAME, USER, PASSWORD, HOST, and PORT values with the appropriate values for your MySQL database.
Once you have configured your settings, you can run the migrate command to create the necessary database tables:
python manage.py migrate
This will create the tables in your MySQL database that are needed by Django. You should now be able to use your MySQL database with Django.
In mysite.settings.py I have:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': os.path.join(BASE_DIR, 'test'),
#'NAME': 'test',
'USER': 'root',
'PASSWORD': 'password',
'HOST': 'localhost',
'PORT': '3306',
}}
When I run 'python manage.py migrate' in the PyCharm terminal, nothing happens, no error message etc. No new tables are created in the database specified. I tried two things for NAME as you can see.
MySQL Server version 8.0.19
MySQL Connector/Python 8.0.19
Python version 3.8
In PyCharm I have package mysqlclient 1.4.6 installed.
Any advice on how to find the problem? How to get an error message?
Thank you
DATABASES property specifies your DB configurations. Now NAME is the property which specifies your database name.
Currently here 'NAME': os.path.join(BASE_DIR, 'test'), won't work as it will give you something like C:/YourUser/YourPath... so this string is not a valid db name. basically (os.path.join() returns a path to your project directory)
First create a db manually on MySql, note the name and put it in property as 'Name': DBNAME in SETTINGS.py.
(Make sure you have your environment set while running following commands)
Then try python manage.py makemigrations for checking migration changes, if everything goes fine up till here then fire python manage.py migrate command.
I just downloaded a newer version of MAMP (3.2.1) and i noticed that this Version has Python installed and also seems to handle SQLite Databases.
Shouldn't I be able to manage Django Projects with it?
Where and how would i install it?
I found some Posts in the Web (before my new MAMP release) where People already trying to get MAMP + Django to work with MySQL but those seemed more complicated to me then the usual setup with Virtualenv + SQLite/Postgres.
I'm pretty new to django but starting a project at the time seems quite simple to me.
If Django would work with MAMP together what would be the advantages?
Anyone has already experiences or useful links?
OK i gues working with MAMP MySQL has the advantage that i can easy import/export Database with php MyAdmin tool.
Anyway based on tanorix answer here how for me Django worked with MAMP MySQL Database:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'projectdb',
'USER': 'root',
'PASSWORD': 'root',
'HOST': '/Applications/MAMP/tmp/mysql/mysql.sock',
'PORT': '8888',
}
}
Then
python manage.py migrate
I don't have knowledge about MAMP but I can give you some elements to put Django Database with WAMP, so I think it can be the same manipulation:
First, in MAMP, you need to create a database, call it : projectdb.
Then, at your settings.py, update your variable DATABASES like this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'projectdb', # Or path to database file if using sqlite3.
# The following settings are not used with sqlite3:
'USER': 'root',
'PASSWORD': '',
'HOST': '127.0.0.1', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
'PORT': '', # Set to empty string for default.
}
}
Then, if you are using South, at your shell write this:
python manage.py schemamigration <name of your app> --init
python manage.py syncdb # => create your tables at your MAMP
python manage.py migrate
I'm currently working on building a Django app. I'm following the "tangowithdjango" tutorial, which uses Django 1.54. In their tutorial, they use Sql-lite, but I'm planning on building this app for most robust purpose, which is why I'm attempting to connect MySQL instead.
Needless to say, it's been a nightmare. I can't get MySQL to connect for the life of me.
Here's what my settings.py looks like:
DATABASE_PATH = os.path.join(PROJECT_PATH, 'app.db')
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'rideb',
'USER': 'root',
'PASSWORD': 'nantucket',
#'HOST': 'localhost', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
#'PORT': '', # Set to empty string for default.
}
}
And here's my output I'm getting...
(rideb)grantmcgovern#gMAC:~/Dropbox/Developer/Projects/RideB/master$ python manage.py syncdb
Segmentation fault: 11
I've installed python-mysqldb, and now I'm simply getting this, and I'm very perplexed to say the least. Is it some Django compatibility issue?
Everything works fine as the tutorial suggests with SQL-lite, but not looking to use that.
OS:
Mac OSX 10.10 Yosemite
MySQL (installed via .dmg on Oracle's site):
Server version: 5.6.19 MySQL Community Server (GPL)
I had a similar problem and it turns out it was related to incorrect mysql implementation on my Mac (OS X 10.10 Yosemite). I had "mysql-connector-c" installed instead of "mysql". Uninstalling "mysql-connector-c" (brew uninstall mysql-connector-c) and installing "mysql" (brew install mysql) resolved the problem right away.
To find out if you are facing this exact problem as I did, open the Console app on your Mac, go to User Diagnostic Reports and look for the report for your crash (should start with Python_). Under queue, if it shows you "0 libmysqlclient.18.dylib", then you have the same problem as I had.
As already mentioned you do not need DATABASE_PATH.
My working configuration looks like:
DATABASES = {
'default': {
'ENGINE': 'mysql.connector.django',
'NAME': 'db_name',
'USER': 'db_user',
'PASSWORD': 'db_pass',
'HOST': '127.0.0.1',
}
}
I am using a different engine, because it is required for Python3. → see documentation
After that you have to create the database and the user. Do not forget to give all needed rights to the user.
With python manage.py migrate your database is populated with your models.
syncdb the predecessor to migrate will be removed in Django 1.9
I want to move away from PHP a little and learn Python. In order to do web development with Python I'll need a framework to help with templating and other things.
I have a non-production server that I use to test all of web development stuff on. It is a Debian 7.1 LAMP stack that runs MariaDB instead of the common MySQL-server package.
Yesterday I installed Django and created my first project called firstweb. I have not changed any settings yet.
Here is my first big piece of confusion. In the tutorial I followed the guy installed Django, started his first project, restarted Apache, and Django just worked from then on. He went to his browser and went to the Django default page with no problems.
Me however, I have to cd into my firstweb folder and run
python manage.py runserver myip:port
And it works. No problem. But I'm wondering if it is supposed to work like this, and if this will cause problems down the line?
My second question is that I want to set it up so it uses my MySQL database. I go into my settings.py under /firstweb/firstweb and I see ENGINE and NAME but I'm not sure what to put here.
And then in the USER, PASSWORD, and HOST areas is this my database and its credentials? If I am using localhost can I just put localhost in the HOST area?
MySQL support is simple to add. In your DATABASES dictionary, you will have an entry like this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': 'localhost', # Or an IP Address that your DB is hosted on
'PORT': '3306',
}
}
You also have the option of utilizing MySQL option files, as of Django 1.7. You can accomplish this by setting your DATABASES array like so:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}
You also need to create the /path/to/my.cnf file with similar settings from above
[client]
database = DB_NAME
host = localhost
user = DB_USER
password = DB_PASSWORD
default-character-set = utf8
With this new method of connecting in Django 1.7, it is important to know the order connections are established:
1. OPTIONS.
2. NAME, USER, PASSWORD, HOST, PORT
3. MySQL option files.
In other words, if you set the name of the database in OPTIONS, this will take precedence over NAME, which would override anything in a MySQL option file.
If you are just testing your application on your local machine, you can use
python manage.py runserver
Adding the ip:port argument allows machines other than your own to access your development application. Once you are ready to deploy your application, I recommend taking a look at the chapter on Deploying Django on the djangobook
Mysql default character set is often not utf-8, therefore make sure to create your database using this sql:
CREATE DATABASE mydatabase CHARACTER SET utf8 COLLATE utf8_bin
If you are using Oracle's MySQL connector your ENGINE line should look like this:
'ENGINE': 'mysql.connector.django',
Note that you will first need to install mysql on your OS.
brew install mysql (MacOS)
Also, the mysql client package has changed for python 3 (MySQL-Client works only for python 2)
pip3 install mysqlclient
To the very first please run the below commands to install python dependencies otherwise python runserver command will throw error.
sudo apt-get install libmysqlclient-dev
sudo pip install MySQL-python
Then configure the settings.py file as defined by #Andy and at the last execute :
python manage.py runserver
Have fun..!!
If you are using python3.x then Run below command
pip install mysqlclient
Then change setting.py like
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB',
'USER': 'username',
'PASSWORD': 'passwd',
}
}
As all said above, you can easily install xampp first from https://www.apachefriends.org/download.html
Then follow the instructions as:
Install and run xampp from http://www.unixmen.com/install-xampp-stack-ubuntu-14-04/, then start Apache Web Server and MySQL Database from the GUI.
You can configure your web server as you want but by default web server is at http://localhost:80 and database at port 3306, and PhpMyadmin at http://localhost/phpmyadmin/
From here you can see your databases and access them using very friendly GUI.
Create any database which you want to use on your Django Project.
Edit your settings.py file like:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'HOST': '127.0.0.1',
'PORT': '3306',
'USER': 'root',
'PASSWORD': '',
}}
Install the following packages in the virtualenv (if you're using django on virtualenv, which is more preferred):
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
That's it!! you have configured Django with MySQL in a very easy way.
Now run your Django project:
python manage.py migrate
python manage.py runserver
Actually, there are many issues with different environments, python versions, so on. You might also need to install python dev files, so to 'brute-force' the installation I would run all of these:
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient
You should be good to go with the accepted answer. And can remove the unnecessary packages if that's important to you.
Run these commands
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient
Then configure settings.py like
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_db',
'HOST': '127.0.0.1',
'PORT': '3306',
'USER': 'root',
'PASSWORD': '123456',
}
}
Enjoy mysql connection
Install mysqlclient
sudo pip3 install mysqlclient
if you get error:
Command "python setup.py egg_info" failed with error code 1 in
/tmp/pip-install-dbljg4tx/mysqlclient/
then:
1. sudo apt install libmysqlclient-dev python-mysqldb
2. sudo pip3 install mysqlclient
Modify settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'website',
'USER': 'root',
'PASSWORD': '',
'HOST': '127.0.0.1',
'PORT': '3306',
'OPTION': {'init_command':"SET sql_mode='STRICT_TRANS_TABLE',"},
}
}
Andy's answer helps but if you have concern on exposing your database password in your django setting, I suggest to follow django official configuration on mysql connection: https://docs.djangoproject.com/en/1.7/ref/databases/
Quoted here as:
# settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}
# my.cnf
[client]
database = NAME
user = USER
password = PASSWORD
default-character-set = utf8
To replace 'HOST': '127.0.0.1' in setting, simply add it in my.cnf:
# my.cnf
[client]
database = NAME
host = HOST NAME or IP
user = USER
password = PASSWORD
default-character-set = utf8
Another OPTION that is useful, is to set your storage engine for django, you might want it in your setting.py:
'OPTIONS': {
'init_command': 'SET storage_engine=INNODB',
}
settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django',
'USER': 'root',
'PASSWORD': '*****',
'HOST': '***.***.***.***',
'PORT': '3306',
'OPTIONS': {
'autocommit': True,
},
}
}
then:
python manage.py migrate
if success will generate theses tables:
auth_group
auth_group_permissions
auth_permission
auth_user
auth_user_groups
auth_user_user_permissions
django_admin_log
django_content_type
django_migrations
django_session
and u will can use mysql.
this is a showcase example ,test on Django version 1.11.5:
Django-pool-showcase
Follow the given steps in order to setup it up to use MySQL database:
1) Install MySQL Database Connector :
sudo apt-get install libmysqlclient-dev
2) Install the mysqlclient library :
pip install mysqlclient
3) Install MySQL server, with the following command :
sudo apt-get install mysql-server
4) Create the Database :
i) Verify that the MySQL service is running:
systemctl status mysql.service
ii) Log in with your MySQL credentials using the following command where -u is the flag for declaring your username and -p is the flag that tells MySQL that this user requires a password :
mysql -u db_user -p
iii) CREATE DATABASE db_name;
iv) Exit MySQL server, press CTRL + D.
5) Add the MySQL Database Connection to your Application:
i) Navigate to the settings.py file and replace the current DATABASES lines with the following:
# Database
# https://docs.djangoproject.com/en/2.0/ref/settings/#databases
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/etc/mysql/my.cnf',
},
}
}
...
ii) Next, let’s edit the config file so that it has your MySQL credentials. Use vi as sudo to edit the file and add the following information:
sudo vi /etc/mysql/my.cnf
database = db_name
user = db_user
password = db_password
default-character-set = utf8
6) Once the file has been edited, we need to restart MySQL for the changes to take effect :
systemctl daemon-reload
systemctl restart mysql
7) Test MySQL Connection to Application:
python manage.py runserver your-server-ip:8000
This is a considerably old question but if anyone is working on any latest versions of python and django you can follow the following steps
Note - Versions
Python version - 3.9.5
Django version - 3.2.4
MySQL server version - 5.7
After installing django, run the following command
pip install mysqlclient
In my IDE if I do pip list this is the list of Packages and Versions
Package Version
----------- -------
asgiref 3.3.4
Django 3.2.4
mysqlclient 2.0.3
pip 21.1.2
pytz 2021.1
setuptools 57.0.0
sqlparse 0.4.1
Now, make sure you already have created the Database schema you are going to use.
In the settings.py file of your django project under DATABASES change
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
}
}
to
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': 'localhost', # Or an IP Address that your DB is hosted on
'PORT': '3306',
}
}
You should be able to run both
python manage.py makemigrations
and
python manage.py migrate
You must create a MySQL database first. Then go to settings.py file and edit the 'DATABASES' dictionary with your MySQL credentials:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'YOUR_DATABASE_NAME',
'USER': 'YOUR_MYSQL_USER',
'PASSWORD': 'YOUR_MYSQL_PASS',
'HOST': 'localhost', # Or an IP that your DB is hosted on
'PORT': '3306',
}
}
Here is a complete installation guide for setting up Django to use MySQL on a virtualenv:
http://codex.themedelta.com/how-to-install-django-with-mysql-in-a-virtualenv-on-linux/
python3 -m pip install mysql-connector
pip install mysqlclient
