Django implements a simple music player 1

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'player'
]

configuration database

Set database configuration

In settings.py DATABASES

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mymp3',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': 'localhost',
        'PORT': '3306'
    }
}

Set pymysql library reference

Add at the top of the __init.py file in the project directory

import pymysql

pymysql.install_as_MySQLdb()

create database

Create database mymp3, select utf8mb4.

Create data table

Generate table migration file

python manage.py makemigrations

Execute table migration

python manage.py migrate

Configure time zone

Configure time zone: modify it to China Shanghai time zone

TIME_ZONE = 'UTC'

changed to

TIME_ZONE = 'Asia/Shanghai'

configuration language

Configuration language: modify it to Simplified Chinese

LANGUAGE_CODE = 'en-us'

changed to

LANGUAGE_CODE = 'zh-hans'

Configure sub-app routing

Create a urls.py file in the player application directory

The content of Urls.py is as follows

from django.urls import path


urlpatterns = [
    # path('admin/', admin.site.urls),
]

The sub-application route is added to the main route

Route urls.py in the mypm3 project directory to introduce sub-application routes

from django.contrib import admin
from django.urls import path, include


urlpatterns = [
    path('admin/', admin.site.urls),

    # 增加路由 指向player urls
    path(r'player/', include(('player.urls', 'player'))),
]

Create a project template

Create project template path

Create templates/application name in the mymp3 directory

As shown below:

Set project template path

Modify the TEMPLATES parameter in settings.py

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

Note: the os library needs to be introduced

static file directory

Create static file directory

It is necessary to create the static files to be used such as css, js, images and other file directories first

Create static/application name/js|css|img directory under mymp3

As shown below

Configure static file directory

Configure the static path used in settings.py

# Static files (CSS, JavaScript, Images)

# https://docs.djangoproject.com/en/3.2/howto/static-files/


STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]
