REST Firestore Example

Overview

The example is as much for reading as executing. The example depends on firestore4kivy.

The example executes in two passes.

The first pass validates user creation, login, and basic Firestore operations, and saves public and private documents. Close or pause the app. You can view the contents of saved documents in Firebase.

The second pass validates login via a token, and validates some complex update operations. All documents and the user are removed from Firestore.

Setup

Assuming you have created and initialized a Firebase project

• Specify the project ID and Key in main.py.
• Specify the Firestore Database Rules.
• Install the dependencies.

Specify the project ID and Key

Get the apiKey and Project ID for your project from Firebase->Project Overview->Project settings->General and replace these placeholders in main.py:

APIKEY = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'
PROJECT_ID = 'bbbbbbbbbb'

Specify the Firestore Database Rules:

In Firebase->Build->Firestore Database->Rules replace the default rules with these rules, then publish.

service cloud.firestore {
  match /databases/{database}/documents {
    match /id/{userId} {
      allow read, write: if request.auth != null && request.auth.uid == userId
    }
    match /data/{userId} {
      allow read, write: if request.auth != null && request.auth.uid == userId
    }
    match /shared/configuration {
      allow read, write: if request.auth != null
    }
  }
}
