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
class CustomerRouter:“”“用于控制auth应用程序中模型的所有数据库操作的路由器 . ”“”def db_for_read(self,model,** hints):“”“尝试读取auth模型转到auth_db . ”“”如果model._meta.app_label =='customer':return'customer_data'返回None
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
建议的那样,您需要安装sqlite3 cli才能使用dbshell
命令 .
