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_lognode2:/django/mysite#ls -ltrtotal 64-rwxrwxrwx 1 root root 804 Oct 25 2017 manage.py-rwxrwxrwx 1 root root 608 Nov 25 2017 query_mysql.pydrwxrwxrwx 3 root root 4096 Nov 27 2017 formdrwxrwxrwx 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__.pycdrwxrwxrwx 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.piddrwxrwxrwx 7 root root 4096 Dec 12 2017 staticdrwxrwxrwx 4 root root 4096 Jan 28 2018 blogdrwxrwxrwx 2 root root 4096 Sep 16 2018 portaldrwxrwxrwx 2 root root 4096 Apr 24 10:15 mysitedrwxrwxrwx 4 root root 4096 Apr 25 02:17 newsdrwxr-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 migrateOperations to perform: Apply all migrations: admin, auth, contenttypes, sessionsRunning 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... OKnode2:/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。
