问题 I am using cloud Firestore database and I have 'users' collection on my root database and in it there are all the users documents (named as the uid) and inside it the data I collect. I wanted to allow users to only read/write to their own collections so I started my security rules with service cloud.firestore { match /databases/{database}/documents { // Allow only authenticated content owners access match /users/{userId}/{documents=**} { allow read, write: if request.auth.uid == userId } } }

问题 I'm building out a quick API for an IOT type app. The structure is that I have a sensor document with latestValue1 and latestVoltage values. Each sensor document also has a collection of readings (an hourly log, let's say.) The Set function works fine to update latestValue1 and latestVoltage , but I'm struggling to work out how to create the readings collection and add a document to it- the code below gives me TypeError: document.collection is not a function app.put('/api/update/:item_id',

问题 I have a collection called creditcards and a collection called ownedcreditcards in Cloud Firestore. I want to perform a query where I JOIN the two collections to find only the creditcards that exists in the creditcards -collection, and not in the ownedcreditcards . From my understanding SQL like JOINS does not exist in Firestore, and you have to retrieve the data in multiple queries. I am trying to call the getAll() -functions (which retrieves all the documents) on both my collections,

问题 How can I limit number of reads/writes from one IP in firestore? P.S. I don't have any authentication in my app 回答1: Limiting any sort of access by IP address is not possible with Cloud Firestore.

问题 I'm trying to write and read to and from my Firestore database from a Ruby script, eventually from a Rails application. It seems like a trivial task but when I run a test script inside IRB it won't let me write or read data. I tried: successfully installed google-cloud-firestore gem downloaded JSON keyfile from within the Firestore console. security rules are set to public (read and write) require 'google/cloud/firestore' # => true # credentials cred = Google::Cloud::Firestore::Credentials
