我在django项目中使用了两个sqlite数据库。一个用于默认,另一个用于customer_data。

这是我的settings.py

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.sqlite3',
    'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},

'customers': {
    'NAME': 'customer_data',
    'ENGINE': 'django.db.backends.sqlite3',
    'USER': 'db2',
    'PASSWORD': 'db2password'
}

}

DATABASE_ROUTERS = ['theapp.routers.CustomerRouter',]

这是我的routers.py

类CustomerRouter:     “””     一个路由器来控制模型中的所有数据库操作     认证申请。     “””     def db_for_read(self,model,**提示):         “””         尝试读取auth模型转到auth_db。         “””         如果model._meta.app_label =='customer':             返回'customer_data'         返回无

def db_for_write(self, model, **hints):
    """
    Attempts to write auth models go to auth_db.
    """
    if model._meta.app_label == 'customer':
        return 'customer_data'
    return None

def allow_relation(self, obj1, obj2, **hints):
    """
    Allow relations if a model in the auth app is involved.
    """
    if obj1._meta.app_label == 'customer' or \
       obj2._meta.app_label == 'customer':
       return True
    return None

def allow_migrate(self, db, app_label, model_name=None, **hints):
    """
    Make sure the auth app only appears in the 'auth_db'
    database.
    """
    if app_label == 'customer':
        return db == 'customer_data'
    return None

正如错误消息You appear not to have the 'sqlite3' program installed所示,您需要安装sqlite3 cli才能使用dbshell命令。
