firestore配置
## Firestore配置
```
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
function signedInAndIsOwner() {
return request.auth.uid != null && resource.data.id == request.auth.uid;
}
match /users/{user_id}{
// if auth and is the owner of the document
allow read, write: if request.auth.uid != null && user_id == request.auth.uid;
// if auth and (is the member of the house or is the owner of the house)
match /houses/{house_id}/{document=**} {
allow read, write: if request.auth.uid != null && (exists(/databases/$(database)/documents/users/$(request.auth.uid)/joinHouses/$(house_id)) || user_id == request.auth.uid);
}
}
}
}
# user_1是house_1的owner
/users/<user_1>/houses/<house_1>/...
# user_1发起邀请 user_2成为其家庭的成员
# 如果 user_2加入了 user_1的 house_1，成为其家庭成员
/users/<user_2>/joinHouses/<house_1>/...
- owner = user_1
后台 watch joinHouses的新增与删除：
当发生新增时，获取 house_id以及house的owner_id，user_2的id以及其nickName/email，找到对应owner的house document，更新其members字段。此处为新增 item <user_2>
/users/<user_1>/houses/<house_1>/...
- members = {"<user_2>": {"nickName": "xxxx", "emailAddress": "xxx"}, "<user_3>": {"nickName": "xxx", "emailAddress": "xxx"}}
```
