is there best practice structuring firebase tables/objects between secure data fields (which users not trusted update themselves) , insecure data, may set themselves? for example, user should free change name or preferences inside own users object, should not free change settings such if they're paid user, email confirmed, etc. or user specific example, user.name should editable user directly, while user.email should changed via our own api, update firebase's record. this seems must common requirement, because see in every table need. e.g. have users , have projects , have tasks within project, etc. , each of data types, there fields user-editable , ones not. so type of approach best practice? here 2 possibilities: secure_data: users: user1: email: user2: projects: tasks: insecure_data: users: user1: name: user2: projects: tasks: or: users: user1: secure: email: insecure: name: projects: projec...
