问题 How do I configure permissions so that a user can only read and write documents where they are the owner? my documents have a top level attribute called owner. I read these docs https://firebase.google.com/docs/firestore/security/secure-data?authuser=0#the_resource_variable and it seems like this should work? service cloud.firestore { match /databases/{database}/documents { match /analysis/{analysis} { allow read, write: if request.auth.email == resource.data.owner } } } however this doesn't

问题 I am using the code below to remove all docs in a collection in Firestore. My question is, how to execute a function which will return the result (promise) of 'deleteCollection' among with an array with the deleted docs? I want to loop over all the docs. I surely can query all the data first, loop through it and than execute this function, but than the data gets read twice. Another option would be creating a empty global variable in which the delete function adds the doc. But how safe is this

Issue When I call the function from the component it always logs [object Promise] and I get a ts lint

问题 Is there a way to add a document with a reference type field to a collection? 回答1: Oh ... I made a mistake ... it's simple - we get a reference DocumentReference type (like this.firestoreService.doc(ref).ref ) and store it in our object. 来源： https://stackoverflow.com/questions/49935811/firestore-angular-angularfire2-adding-document-with-a-reference-type-field
