I just wrote a quick blogpost about the difference between pluck and map on Rails models.

 

The blogpost can be found here: http://ohm.sh/2014/0...and-select.html

 

When using only map, you end up creating a lot of full fletched ruby objects, which you might not want, but with pluck, you'll only create dummy objects from which you can grab your data. pluck does exactly the same as map and select used together.
