_mysql_exceptions.OperationalError: (1049, "Unknown database 'd:/project/wogma/w
ogma'")

我在mysql中执行了如下命令..我已经使用create database创建了wogma数据库n我在mysql中授予了priviliges..in。什么是prb ??

Answer 1

您正在尝试在文件路径中指定数据库（这适用于SQLite）。 MySQL需要一个数据库名称（例如'wogma'）。你必须按照说明安装MySQL，创建一个新的用户和数据库等。看来你在Windows上，所以我不能帮助你。

Answer 2

打开一个sql控制台并输入SHOW DATABASES;
如果显示wogma只是将其放入您的设置中（您使用的是django 1.1）：

DATABASE_ENGINE ='django.db.backends.mysql'

DATABASE_NAME ='wogma'

DATABASE_HOST ='127.0.0.1'

DATABASE_PORT ='3306'
如果不显示，只需在此控制台CREATE DATABASE wogma ;中创建它，然后重新制作步骤。

Answer 3

尝试使用此连接配置：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'MY_DATABASE_NAME',
        'USER': 'root',
        'PASSWORD': 'MY_PASSWORD',
    }
}

但首先，在你的mysql中创建数据库。

Answer 4

按照上述答案，以下代码将无效

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'MY_DATABASE_NAME',
        'USER': 'root',
        'PASSWORD': 'MY_PASSWORD',
    }
 }

您将必须下载MySQL Connector。阅读this帖子以在Django 2.1.x中设置MySQL数据库
