How to delete some user data using Firebase admin sdk?

Question

I need to remove only part of data in user section by key

ref = db.reference(user.uid)
user_data = ref.get()
reqs = user_data['support_req']

for req in reqs:
  print(req)
  print(user_data['support_req'][req])

result:

-NQKyF9j6Fcnd4aeQyW5

{'telephone': '+000000000000'}

I need to remove key and value from database

Answer 1

If you want to delete all the RTDB nodes under the support_req node, the following should do the trick (untested):

support_req_ref = db.reference(user.uid + '/support_req')
support_req_ref.delete()

If you want to delete a specific sub-node of the user's support_req node you need to know its id, e.g. -NQKyF9j6Fcnd4aeQyW5 in your example. Then you should do:

support_req_ref = db.reference(user.uid + '/support_req/-NQKyF9j6Fcnd4aeQyW5')
support_req_ref.delete()
