jython上的数据库Django

Question

请帮助我在django上用jython连接数据库，并在我放置jython manage.py运行服务器时帮助我处理服务器服务器不运行

DATABASES = {
    'default': {
        #'ENGINE': 'doj.backends.zxjdbc.sqlite3',
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'tanagraweb',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': '127.0.0.1',
        'PORT': '3306',
    }
}

和django扔这个：

我研究发现这是mysql的连接器，但我不知道为什么它不起作用如果有人在jython的django上有一个项目，我会非常感激这太难了

Answer 1

虽然MySQLdb是Python/Django社区中使用最广泛的MySql库，但您不能使用它，因为Jython不能使用C扩展。

要在Django中使用Jython，需要安装Django-Jython并将数据库后端设置为'ENGINE': 'doj.db.backends.mysql'

这在Jython 上运行Django的官方文档中有记录

Answer 2

1. 使用"pip-Install-pymmysql"安装pymysql
2. 将以下内容添加到manage.py文件中：

import pymysql

pymysql.install_as_MySQLdb()

3. 在DATABASES设置中，使用：

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