Firebase Realtime Database Rule Access parent variable from child
问题
如何访问变量 $cliente？
auth.token.place == $cliente 比较失败。
auth.token.place 是可以的，我与一个常量进行比较 (auth.token.place == 23)，它可以工作。但 $cliente 与相同的常量比较失败 ($cliente == 23)。
我有以下规则：
{
/* 请访问 https://firebase.google.com/docs/database/security 了解更多关于安全规则的信息。 */
"rules": {
"clientes": {
"$cliente": {
"tvs": {
".read": true,
".write": false,
},
"chats":
{
".read": true,
".write": "auth !== null && auth.token.place == $cliente"
}
}
}
}
}
firebase.database().ref('clientes/' + id + '/chats/' + dest).set({
from: MY_ID,
to: msg_to,
message: " ",
date: Date.now()
});
结构示例：
clientes
2
tvs
...
chats
128_239
{ from: "239"
message: "fngdkfngd dkfjfds"
to: 128,
date: 543657654654
}
我只想让属于相同 $cliente 的用户访问。
我得到了“权限被拒绝”的错误。
英文:
How can I access variable $cliente?
The auth.token.place == $cliente comparison fails.
auth.token.place is fine I compare with a constant (auth.token.place == 23) and it works. But $cliente compared with the same constant fails ($cliente == 23).
I have this rule below:
{
/* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */
"rules": {
"clientes" : {
"$cliente" : {
"tvs" : {
".read": true,
".write": false,
},
"chats" :
{
".read": true,
".write": "auth !== null && auth.token.place == $cliente"
}
}
}
}
}
firebase.database().ref('clientes/'+id+'/chats/'+dest).set({
from: MY_ID,
to: msg_to,
message : " ",
date: Date.now()
});
Structure example:
clientes
2
tvs
...
chats
128_239
{ from: "239"
message:"fngdkfngd dkfjfds"
to:128,
date: 543657654654
}
I just want to give access to users that belongs from the same $cliente.
I am getting PERMISSION DENIED.

I got it.
Actually auth.token.place is a number not a String and @cliente is a String.
So I need to convert to compare. That is how I did.
{
/* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */
"rules": {
"clientes": {
"$cliente": {
"tvs": {
".read": true,
".write": false
},
"chats": {
".read": true,
".write": "auth !== null && ('' + auth.token.place) == $cliente"
}
}
}
}
}
