Django Oracle数据库设置

我只是想连接我的本地oracle数据库和我的django项目，但是我的数据库证书不起作用。实际上，我可以通过sql developer使用该证书连接我的oracle数据库：

我刚刚在django settings_py中使用了这个凭证，

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': 'INTERNAL',
        'USER': 'system',
        'PASSWORD': 'oracle',        
        'HOST':'localhost/xe',
        'PORT':'1521'
    }
}

错误是：

您应该将HOST更改为localhost' or '127.0.0.1，SID为NAME。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': 'xe',
        'USER': 'system',
        'PASSWORD': 'oracle',        
        'HOST':'127.0.0.1',
        'PORT':'1521'
    }
}

字符串
对于将来的参考，如果Oracle配置了服务名称而不是SID，则配置将为：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': '127.0.0.1:1521/service.name',
        'USER': 'system',
        'PASSWORD': 'oracle',        
    }
}

在Django中使用Oracle时需要考虑的另一件事是，当您连接到其他用户（模式）数据库时，您必须在Django模型中设置db_tableMeta option：

class OracleTable(models.Model):
    ... fields ...
    class Meta:
        db_table = '\"OTHERUSER\".\"ORACLETABLE\"'

NAME必须是cx_Oracle.connect中的dsn，在内部'django.db.backends.oracle'尝试连接：

import cx_Oracle
cx_Oracle.connect(user=DATABASES['default']['USER'], password=DATABASES['default']['PASSWORD'], dsn=DATABASES['default']['NAME'])
