How to write .indexOn for dynamic keys in firebase?

Question

I have data set up like this:

Tasks:{
  Group 1:{
    pushid1:{
      date: 18921949021,
      title: \"Do something\"
    },
    pushid2:{
      date: 189219490         


        

Answer 1

I guess you're looking for:

{
  ".read": true,
  ".write": true,
  "rules": {
    "Tasks": {
      "$groupid": {
        ".indexOn": "date"
      }
    }
  }
}

The Firebase documentation is usually a pretty good read. Spending an hour or less in the security guide, will ensure you have a better understanding of this and many other topics.
