问题 It seems odd to me that Firestore would charge me for read queries to locally cached data, but I can't find any clarification to the contrary in the Firestore Pricing document. If I force Firebase into offline mode and then perform reads on my locally cached data, am I still charged for each individual entity that I retrieve? Second, offline users in my app write many small updates to a single entity. I want the changes to persist locally each time (in case they quit the app), but I only need

问题 I have two collections - tenancies and users. A tenancy doc has a field called "landlordID" and is of type REFERENCE (not String). Now in my Firestore Security Rules I want to allow a tenancy to be updated ONLY IF the landlordID field of that tenancy matches with the uid of the user making the request, namely request.auth.uid . Read it as " allow a tenancy document to be updated if the user making the user is authenticated, hence request.auth.uid != null, and the landlordID field's ID should

问题 I am using Firebase Cloud Firestore, and I want to modify my rules to restrict users from querying a collection. This should not be allowed: firestore().collection("users").get() But this should be allowed: firestore().collection("users").doc("someUserId").get() Currently, my rules look like this: match /users/{userId} { allow read; } but this rule allows the "users" collection to be queried. How can I allow single document gets, but not collection queries? 回答1: You can break read rules into
