Thanks

First you need to have an action that will be called upon clicking the button. Then in the action you can use %x to call your script. For example:
def my_action
result = %x(ruby example.rb)
end
If you want to run the script in the context of the rails application, you will want to use rails runner.
def my_action
result = %x(bin/rails runner example.rb)
end
You can find more useful info about executing shell commands in ruby here.

This question is old but still comes up on the first page of a google search so here is what I use.
The rails runner command will execute the file in the context of your rails app.
rails runner [path to file].rb
Edit: After using this a few times, I found that you can add RAILS_ENV=production to the beginning of the command to specify the environment to run the script in.
