所以我使用Firebase相对较新,我试图找出如何构建我的数据以使其安全和规范化。
我的数据需要基于用户的安全性,在概念上看起来像这样:
{
"users": {
"simplelogin:1": {
"email": "test@test.com",
"id": "1",
"name": "test",
"provider": "password",
"clients": {
"client1": {
"name": "testClient",
"projects": {
"project1": {
"name": "testProject",
"sites": {
"site1": {
"name": "testWobsite",
"hits": {
"hit1": {},
"hit2": {},
"hit3": {}
}
},
"site2": {}
}
},
"project2": {}
}
},
"client2": {
"name": "test",
"projects": {}
},
}
},
"simplelogin:2": {
"email": "test2@test2.com",
"id": "2",
"name": "test2",
"provider": "password",
"clients": {}
}
}
}
如您所见,此处的数据结构非常嵌套...
用户有客户,客户有项目,项目有网站,网站有点击...
所以这是我的主要问题之一 - 我不完全确定如何构造这些数据,以便它不是那么嵌套。
我遇到的另一个问题是弄清楚如何使用Firebase安全规则
本质上,我希望用户能够创建,更新和删除他们拥有的所有数据(客户,项目,站点和点击)
命中应该是可公开写入的,但只能通过拥有它的用户读取
用户应该能够注册和登录,但不能读取或写入任何其他人的数据。
如果有人对此或任何提示或指示有任何想法,任何建议将不胜感激!
谢谢!

这是我尝试对数据进行规范化......任何想法......?

答案 0 :(得分:1)
您需要将数据非规范化为多个表格,其中表格为#34; link"以某种方式相互对待。例如:每个用户都会得到一个client_id列表,每个客户端都会获得一个user_id列表(假设您将以两种方式访问数据)。这是更多数据保持同步,但一旦它是一个扁平结构,你也会发现它将更容易设置你的权限。
现在使用这种嵌套结构对于像Firebase这样的NoSQL后端是非常低效的,因为你必须在获取用户数据时检索所有数据,而你无法告诉他们哪些客户端属于哪个用户而没有遍历所有用户。
