Method that runs an executable file

Ruby
#1

hello,

i am quite new to programming, only began in february this year and am
doing a project for my uni course.

me and my group are using ruby on rails and were wondering if it is
possible to create a method that when run, gets a rakefile to execute a
database migrate?

would greatly appreciate any help here

There are several general ways in Ruby to launch an external command:

Though, be aware, particularly for web apps, of potential security
issues that can be introduced:

thank you,

i have never used IRB before so am a little unfamiliar with the coding
on the page, it is still helpful though. i shall try to work through it
and get a method created for executing a rakefile.
