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
答案 0 :(得分:4)
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。
