如何使用python从Firebase数据库检索路径的数据? [英] How do I retrieve a path's data from firebase database using python?

问题描述

我有这个Firebase数据库结构

I have this firebase database structure

我想为企业"下的每个ID打印出库存清单(Inventory).
所以我尝试了这段代码

I want to print out the inventory list(Inventory) for each ID under Businesses.
So I tried this code

db = firebase.database() 
all_users = db.child("Businesses").get()
for user in all_users.each():
    userid = user.key()
    inventorydb = db.child("Businesses").child(userid).child("Inventory")
    print(inventorydb)

但是我只有这个

  <pyrebase.pyrebase.Database object at 0x1091eada0>

我在做错什么，如何遍历每个企业ID并打印出其库存?

what am I doing wrong and how can I loop through each Business ID and print out their inventory?

推荐答案

首先，您正在打印数据库对象.您需要保持数据静止.

First, you're printing a Database object. You need to get the data still.

您似乎已经知道如何以及孩子们._{或者您只是复制了示例而没有理解...}

You seem to already know how to get that as well as the children. _{Or you only copied the examples without understanding it...}

无论哪种方式，您都可以尝试

Either way, you can try this

db = firebase.database() 
businesses = db.child("Businesses")
for userid in businesses.shallow().get().each():
    inventory = businesses.child(userid).child("Inventory").get()
    print( inventory.val() )

在旁注中， National_Stock_Numbers 看起来应该是名称的值，而不是孩子的键

On a side note, National_Stock_Numbers looks like it should be a value of the name, not a key for a child
