Firebase Storage Rules with Custom Claims

I am unable to get Firebase Storage work with custom rules and using custom claims.

I am unable to get Firebase Storage work with custom rules and using custom claims.

In my Python Admin panel, I do the following to create the user and assign a claim client_id:

# Standard Auth
import firebase_admin
from firebase_admin import db, storage, auth
cred   = firebase_admin.credentials.Certificate('path_to_cert_json')
app    = firebase_admin.initialize_app(cred, 'config')
bucket = storage.bucket(app=app)
Create User

auth.create_user(email=email)

Create custom claims

auth.set_custom_user_claims(uid, {'client_id': client_id})

Then for Firebase rules, I try to allow the user to only read (or download) files when the file is in a subfolder with the client_id:

File structure on storage:

/{environment}/{client_id}/other_folders_and_files

I set the following storage rules:

service firebase.storage {
match /b/{bucket}/o {
match /{environment}/{client_id}/{allPaths=**} {
allow read: if request.auth.token.client_id == client_id
}
}
}

But that gives me an error that Permission is denied.

What am I doing wrong?

Note:

  • client_id is correct and the folder structure is correct, have checked this a million times.

Learn Hands-On Python Programming By Creating Projects, GUIs and Graphics

Python is a dynamic modern object -oriented programming language
It is easy to learn and can be used to do a lot of things both big and small
Python is what is referred to as a high level language
Python is used in the industry for things like embedded software, web development, desktop applications, and even mobile apps!
SQL-Lite allows your applications to become even more powerful by storing, retrieving, and filtering through large data sets easily
If you want to learn to code, Python GUIs are the best way to start!

I designed this programming course to be easily understood by absolute beginners and young people. We start with basic Python programming concepts. Reinforce the same by developing Project and GUIs.

Why Python?

The Python coding language integrates well with other platforms – and runs on virtually all modern devices. If you’re new to coding, you can easily learn the basics in this fast and powerful coding environment. If you have experience with other computer languages, you’ll find Python simple and straightforward. This OSI-approved open-source language allows free use and distribution – even commercial distribution.

When and how do I start a career as a Python programmer?

In an independent third party survey, it has been revealed that the Python programming language is currently the most popular language for data scientists worldwide. This claim is substantiated by the Institute of Electrical and Electronic Engineers, which tracks programming languages by popularity. According to them, Python is the second most popular programming language this year for development on the web after Java.

Python Firebase Real Time Database Tutorial with Example

Python Firebase Real Time Database Tutorial with Example

Python Firebase Real Time Database Tutorial with Example - in this Python tutorial, we are going to talk about Python Firebase Real Time Database. Firebase is a google product which offers so many useful features: Firebase Real Time Database, Push Notifications, Firebase Authentication, Firebase Cloud Messaging, Firebase Test Lab For Android, Firebase Crash Reporting, Firebase Notification, Firebase App Indexing and many more

Python Firebase Real Time Database – in this Python article iam going to talk about Python Firebase Real Time Database.

So first of all Firebase is platform which allow to build web and mobile applications without server

side programming language. You can store users data on its real-time database which sync

data among users data in no time.

Firebase is a google product which offers so many useful features. Like

_1: Firebase Real Time Database
_2: Push Notifications
3: Firebase Authentication
_4: Firebase Cloud Messaging
_5: Firebase Test Lab For Android
6: Firebase Crash Reporting
_7: Firebase Notification
_8: Firebase App Indexing and many more _

So in this article we are going to use Real Time Database Feature of Firebase.

OK when you want to use Firebase in Python you need to install some packages

pip install requests

pip install python-firebase

So now this is the code for inserting data to Firebase Real Time database

from firebase import firebase


firebase = firebase.FirebaseApplication('URL of Database', None)
data =  { 'Name': 'John Doe',
          'RollNo': 3,
          'Percentage': 70.02
          }
result = firebase.post('/python-example-f6d0b/Students/',data)
print(result)

OK now in this line of code FirebaseApplication takes two parameters; one is URL of database and second is authentication details for database

because for this project we have not set a rule by this reason we have given None in the second parameter.

firebase = firebase.FirebaseApplication('URL of Database', None)

And in this line of code we are going to insert data to our table

result = firebase.post('/python-example-f6d0b/Students/',data)

OK this was for inserting data and now we want to retrieve the data, you can use this code

**Retrieving The Data **
from firebase import firebase



firebase = firebase.FirebaseApplication('URL of database', None)
result = firebase.get('/python-example-f6d0b/Students/', '')
print(result)
Updating The Data
from firebase import firebase

firebase = firebase.FirebaseApplication('Database URL', None)
firebase.put('/python-example-f6d0b/Students/-LjLUhaWGuxNd5gOEmse','Name','Bob')
print('Record Updated')
Deleting The Data
from firebase import firebase

firebase = firebase.FirebaseApplication('URL Of Database', None)
firebase.delete('/python-example-f6d0b/Students/', '-LjLUhaWGuxNd5gOEmse')
print('Record Deleted')
