python - 构建 Firebase 数据库

Question

我正在关注this构建 Firebase 数据的教程。接近尾声时，它说:

With this kind of structure, you should keep in mind to update the data at 2 locations under the user and group too. Also, I would like to notify you that everywhere on the Internet, the object keys are written like "user1","group1","group2" etc. where as in practical scenarios it is better to use firebase generated keys which look like '-JglJnGDXcqLq6m844pZ'. We should use these as it will facilitate ordering and sorting.

基于此，我假设最终结果应该如下:

我正在使用this python wrapper发布数据。

我怎样才能实现这个目标？

Answer 1

当您使用这样的行将数据写入 Firebase 数组(例如在 Javascript 中)时

var newPostKey = firebase.database().ref().child('users').push().key;

var updates = {item1: value1, item2: value2};

return firebase.database().ref().update(updates);

如描述here ，您将获得“推送”数据的生成 key 。在上面的示例中 newPostKey 将包含此生成的 key

更新
要使用 Python 包装器回答更新的问题:
在您链接到的页面中查找“保存数据”部分。

代码看起来像这样；

data = {"Title": "The Animal Book"}
book = db.child("AllBooks").push(data)

data = {"Title": "Animals"}
category = db.child("Categories").push(data)

data = {category['name']: true }
db.child("AllBooks").child(book['name']).child("categories").push(data)
