Sometimes when we’re debugging some Ruby code, it is good to know what code has called the method we’re looking at. It is something I routinely like to know.
There are a few different ways we can go about this, but the one I reach for more often than not is the Ruby kernel method caller.
This video talks through what `caller` does with a short example, and shows a few different ways I've used it to get what I need.
