django框架创建应用操作示例
作者：zhaoyangjian724
这篇文章主要介绍了django框架创建应用操作,结合实例形式分析了Django框架的安装、创建项目、创建数据库及创建应用相关操作技巧,需要的朋友可以参考下
本文实例讲述了django框架创建应用操作。分享给大家供大家参考，具体如下：
18.1.5 安装Django
安装Django
node2:/root#pip install Django /usr/local/python27/lib/python2.7/site-packages/cryptography/hazmat/primitives/constant_time.py:26: CryptographyDeprecationWarning: Support for your Python version is deprecated. The next version of cryptography will remove support. Please upgrade to a 2.7.x release that supports hmac.compare_digest as soon as possible. utils.DeprecatedIn23, Looking in indexes: http://mirrors.aliyun.com/pypi/simple/ Requirement already satisfied: Django in /usr/local/python27/lib/python2.7/site-packages (1.11.9) Requirement already satisfied: pytz in /usr/local/python27/lib/python2.7/site-packages (from Django) (2017.2) You are using pip version 18.1, however version 19.1.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
18.1.6 在Django 中创建项目:
node2:/django/mysite#django-admin.py startproject learning_log node2:/django/mysite#ls -ltr total 64 -rwxrwxrwx 1 root root 804 Oct 25 2017 manage.py -rwxrwxrwx 1 root root 608 Nov 25 2017 query_mysql.py drwxrwxrwx 3 root root 4096 Nov 27 2017 form drwxrwxrwx 2 root root 4096 Nov 27 2017 online -rwxrwxrwx 1 root root 262 Dec 5 2017 test.py -rwxrwxrwx 1 root root 646 Dec 5 2017 test.pyc -rwxrwxrwx 1 root root 113 Dec 5 2017 __init__.pyc drwxrwxrwx 2 root root 4096 Dec 5 2017 home -rwxrwxrwx 1 root root 0 Dec 5 2017 __init__.py -rwxrwxrwx 1 root root 27 Dec 5 2017 a1.py -rwxrwxrwx 1 root root 5 Dec 5 2017 celerybeat.pid drwxrwxrwx 7 root root 4096 Dec 12 2017 static drwxrwxrwx 4 root root 4096 Jan 28 2018 blog drwxrwxrwx 2 root root 4096 Sep 16 2018 portal drwxrwxrwx 2 root root 4096 Apr 24 10:15 mysite drwxrwxrwx 4 root root 4096 Apr 25 02:17 news drwxr-xr-x 3 root root 4096 Apr 25 09:25 learning_log
/django/mysite/learning_log/learning_log
INSTALLED_APPS = ( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'learning_log',
18.1.7 创建数据库
Django 将大部分与项目相关的信息都存储在数据库中,因此我们需要创建一个供Django使用的数据库
配置mysql数据库
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'tlcb',
'USER': 'root',
'PASSWORD': '1234567',
'HOST': '192.168.137.3',
'PORT': '3306',
}
}
node2:/django/mysite/learning_log#python manage.py migrate Operations to perform: Apply all migrations: admin, auth, contenttypes, sessions Running migrations: Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add... OK Applying contenttypes.0002_remove_content_type_name... OK Applying auth.0002_alter_permission_name_max_length... OK Applying auth.0003_alter_user_email_max_length... OK Applying auth.0004_alter_user_username_opts... OK Applying auth.0005_alter_user_last_login_null... OK Applying auth.0006_require_contenttypes_0002... OK Applying auth.0007_alter_validators_add_error_messages... OK Applying auth.0008_alter_user_username_max_length... OK Applying sessions.0001_initial... OK node2:/django/mysite/learning_log#
18.1.8 创建应用:
django-admin.py startproject learning_log
希望本文所述对大家基于Django框架的Python程序设计有所帮助。
