Rails quick tip: generate and destroy

Rails generators are often known to be a one way street. Often people new to
rails think if they generate the wrong thing they are stuck. Not true! So here
we go, happens to me all the time:

$ rails g controller ReportsController index

Oh right generate just takes the name without the extension. No need to hunt
down the generated files:

$ rails d controller ReportsController index
$ rails g controller Reports index

Just run d for destroy and generate again. Just thought to point this out!
