Cloud Firestore: Rules

Question

I need to have a way to modify my data in the database without opening it to everyone. I tried doing the https://firebase.google.com/docs/admin/setup?authuser=1 where I downloaded the .json file and everything and set my rules to:

match /{document=**
  allow read, write: if request.auth.uid == 'admin';` 

but it's still won't work saying insufficient privilege's. I know my firebase is set up correctly because when I change the rules to allows everyone read and write it works.

Answer 1

The following Firestore rule checks that the request being made to your database contains a uid

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: request.auth.uid != null;
    }
  }
}

Or if you want to check if the role of user is 'admin'

match /users/{userRole} {
   allow read: if userRole ==  'admin';
}

Comments

That didn't seem to work for my file. I think I have more of a issue with the local code then the rules on the firebase it self. Meaning when my users make a request to the database for the data I don't pass credentials that match the firebase rules.
