Get a document name based in the rules

Question

I'm searching to add a rule in my Firestore database. The rule is to allow write documents if the document equal the request.auth.uid. I don't know how to search the name of my document in the rules.

This is my code where is missing this part :

service cloud.firestore {
  match /databases/{database}/documents {
  match /users/{anyDocument} {
      allow write: if request.auth != null && request.auth.uid == ?????????;
      allow read
    } 
  }
}

Answer 1

It's unclear in your question, but I'm assume you want to enforce only writing a document who's id is equal to the users auth id.

match /users/{anyDocument} {

Because of this line, the document id will be set to the variable anyDocument, so this is what you want to check.

allow write: if request.auth != null && request.auth.uid == anyDocument;
