Safely handle inserting object field values

[JoshWillik]

Problem

Hi, I was trying to insert a uuid into a record, and it caused a 400 error because the finished record looked like this

event,foo=bar id=a605d377-47bd-4d9a-8b6e-c9ed66bed255

The error occurs because the uuid isn't quoted:

event,foo=bar id="a605d377-47bd-4d9a-8b6e-c9ed66bed255"

This is because the uuid was a Uuid object, not a string (which I didn't realize at the time).

Solution

This function should stringify objects before processing them.

if (is_object($field) {
    $field = $field->toString();
}

The object will eventually be stringified when inserted into the line record, so may as well do it early so it can be quoted if needed.
