Cloud Firestore

Every database needs rules to give limited permissions to users and full control to the admin. So, we will add rules to Firestore.

Rules#

1. First, log in to your Firebase console and select your project.
2. Navigate to the “Authentication” section from the left-hand menu.
3. enable email and password authentication and google authentication from the sign-in method tab.
4. Click on the “Users” tab and then click on the “Add User” button at the top of the page.
5. add a user (it will be your admin user) and copy his uid.
6. Go to Firebase → Cloud Firestore → Rules and paste these rules:

Important: Replace ADMIN_UID with your admin UID.

rules_version = '2';
ervice cloud.firestore {
match /databases/{database}/documents {

// TODO: Put your admin UID
  function adminUid() {
  return "Put-Admin-Uid-Here";
}

// allow read,write to admin
  match /{document=**} {
  allow read, write: if request.auth.uid == adminUid();
}

 // Restaurants collection
// Allow read only to normal users
match /restaurants/{restaurantId} {
  allow read: if request.auth != null;
}

//for collection group
match /{path=**}/products/{productId} {
allow read,write: if request.auth != null;

}

// users collection
// allow users to read and write their own data
match /users/{userId}{
allow read, write: if userId==request.auth.uid;
	}

// allow users to read and write their orders
match /users/{userId}/orders/{ordersId}{
allow read, write: if userId==request.auth.uid;
	}



// allow users to read and write their own favorites
match /users/{userId}/favorites/{favoriteId}{
allow read, write: if userId==request.auth.uid;
	}

}}
