我正在尝试构建我的Firebase数据库，因此所有用户的练习都属于同一个postkey，因为我正在为每个练习做一个新的推送请求，他们目前没有正确的结构，如此处所示：http://imgur.com/a/Wz93o
我的Firebase代码是：
function writeNewWorkout() {
// A post entry.
console.log(payload);
var uid = firebase.auth().currentUser.uid;
// Get a key for a new Post
var newPostKey = firebase.database().ref().child('Workout').push().key;
// Write the new post's data
var updates = {};
updates[uid + '/Workout/' + newPostKey + "/" + exercise] = payload; // Add UID?
return firebase.database().ref().update(updates);
}
和收集用户条目的提交功能（动态字段输入）：
$('.submitExercise').click(function () {
var reps = [];
$.each($('.repsClass'), function () {
reps.push($(this).val());
});
if (reps.length == 0) {
reps = "none";
}
var weight = [];
$.each($('.weightClass'), function () {
weight.push($(this).val());
});
if (weight.length == 0) {
weight = "none";
}
exercise = document.getElementById("autocomplete-input").value;
alert(exercise);
alert(reps);
alert(weight);
for (var i = 0; i <= reps.length - 1; i++)
{
payload["exercise"] = exercise,
payload["reps" + i] = reps[i],
payload["weight" + i] = weight[i];
}
writeNewWorkout();
});
有人可以告诉我应该做出哪些改变吗？
我想我需要一个for循环和一个更新方法，我只是不确定如何构建它。
编辑：
我想出了以下内容，而不是使用postkey，我使用的是日期变量（因为它是可预测的），如下所示：http://imgur.com/a/0IgPc
这是否可以接受？
