Django: 0. Preparing environment

Set up python and pip on linux system for correct django version.

You can see here:

https://docs.djangoproject.com/ko/2.0/faq/install/

In this case, I will use Python 3.6 and Django 2.0

-Upgrade pip tool

# pip install --upgrade pip

-Installing Django

# pip install django~=2.0.5

-Starting the project

(env) # django-admin startproject project_name .

In the project

dir .

ㄴmanage.py

ㄴproject_name

ㄴsettings.py

ㄴurls..py

ㄴwsgi.py

ㄴ__init__.py

manage.py: A script for managing web app

settings.py: Configuration of website

urls.py: Pattern list which is used by urlresolver

-settings.py: add or edit few lines on it.

In this case, I'm going to use Mariadb on local server for django database.

...

#DATABASE

DATABASES = {

    'default': {

        #'ENGINE': 'django.db.backends.sqlite3',

        #'NAME': os.path.join(BASE_DIR, 'db.sqlite3'

        'ENGINE': 'django.db.backends.mysql',

        'NAME': 'django',

        'USER': 'mariadb',

        'PASSWORD': 'mariadb',

        'HOST': 'localhost',

        'PORT': '3306',

    }

}

...

TIME_ZONE = 'Asia/Seoul'

...

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

-Install mariadb

$ sudo yum install -y mariadb-server

$ sudo mysql_secure_installation

$ systemctl start mariadb

[user1@django ~]$ mysql -u root -p
Enter password: 
 

-Create database to use and user

MariaDB [(none)]> CREATE database db_name;
Query OK, 1 row affected (0.01 sec)
 
MariaDB [(none)]> CREATE user 'user_name'@'localhost' identified by 'user_passwd';
Query OK, 0 rows affected (0.00 sec)
 
MariaDB [(none)]> GRANT ALL on db_name.* TO 'user_name'@'localhost';
Query OK, 0 rows affected (0.00 sec)
 
MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
 

-After editing settings.py

(env) # python manage.py migrate

(djenv) [user1@django django]$ python manage.py migrate
