guys, can any one tell me in security rules for cloud firestore where i can see all methods to validate data using common expression language(CEL) like (hasOnly(),hasAll(),isNumber)
common expression language methods or functions.
You can find a list of all objects, classes and properties in the reference documentation of Firestore security rules.
There is no isNumber function there though. As far as I know that is only defined for security rules of the Realtime Database (see isNumber), which uses a different language.
