我正在尝试在两个不同树之间的数据结构中建立关系。一个是" Spaces"树,另一个是" Depts"。从逻辑上讲,部门(部门)位于空间(空间)内
这个问题来自这个问题:How can I get to the references inside dynamically generated references in firebase?
这是我的数据库结构的图像:
答案 0 :(得分:0)
这似乎是最实用的方法:
将用户节点绑定到建筑物:
模板:
<p>Name: <input type="text" v-model="newBuilding.name"></p>
<p>Address: <input type="text" v-model="newBuilding.address"></p>
数据:
data () {
return {
newBuilding: {
name: '',
address: '',
ownerID: '',
}
}
},
方法:
addBuilding: function () {
// get current user from firebase
let userId = firebase.auth().currentUser.uid;
// create a random pushkey but without pushing it yet
let buildingKey = buildingsRef.push().key
// set the user.uid as building data child "ownerId" value, (the other data nodes where hydrated from the <template>
this.newBuilding.ownerID = userId;
// SET THE NEW BUILDING
buildingsRef.child(buildingKey).set(this.newBuilding);
// SET THE BUILDING PUCHKEY ON A CHILD NODE ON THE **USERS** NODE
usersRef.child(userId).child('isAdmin').child(buildingKey).set(true);
}
我希望这能为你做到。
