Allow Read and write for all child except one

I am using firebase for my project

now I wan to customize my Rule

the Default rules is :

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

which Allow to read and write all data for Authorized users

now I want to Allow read and write all data for Authorized users

and I want to add this too

{
  "rules": {
      "visits": {
      "$visit_id": {
        "mister_id": {
          ".write": "data.val() == ''"
        }
      }
    }
  }

}

Now how Can I add this two Rules

I think you need something like that :

{
    "rules": {
        ".read": "auth != null",
        ".write": "auth != null",
        "visits": {
            "$visit_id": {
                "mister_id": {
                    ".validate": "(data.val() == null) || (data.isString() && (data.val().length == 0))"
                }
            }
        }
    }
}

You can find all what you need with the Firebase Datase Rules documentation.

Haven't try yet but it may be another solution:

{
    "rules": {
        ".read": "auth != null",
        ".write": "auth != null",
        ".validate": "newData.hasChildren(['visit_id', 'mister_id'])"
    }
}
