将对象推送到Firebase的智能方法 [英] Smart way to push object to firebase

问题描述

我有一个要推送到Firebase实时数据库的对象，如下所示:

I have an object that I want to push to the firebase realtime database, looking like this:

userProfile = { name: "Jon", age: 25, gender: "male", ...plenty more attributes}

如果我想在firebase中使用它，可以这样写:

If I want it in firebase, I could write it like this:

return firebase.database().ref('/userProfile').push({
    name: userProfile.name,
    age: userProfile.age,
    gender: userProfile.gender,
    ....
}).

但是由于我有许多具有许多属性的对象，所以我宁愿不手工编写它. push()中不允许循环.我可以像这样推动整个对象:

But since I have plenty of objects with many attributes I would prefer not writing it by hand. Loops are not allowed in push (). I could push the whole object like this:

return firebase.database().ref('/userProfile').push({
    userProfile: userProfile
}).

但是它将创建一个额外的子节点，例如

But it will create an additional child node like

ref/userProfile/123someId/userProfile/name

这是一个不好的做法，因为它不允许使用过滤器，以后再使用.

which is bad practise because it disallows using filters and more later on.

有没有更有效的方法来推送整个对象的属性，而无需写下每个键/值对?

Is there a more effective way to push the attributes of an entire object without writing down every key/value pair?

推荐答案

答案并非易事，但如果有人偶然发现同一问题:

The answer could not be easier, but in case someone else stumbles across the same issue:

firebase.database().ref('/userProfile').push(userProfile)
