Question

I’m very new to rails and I have a script that I run from the console like this

   $ ruby axml2xml.rb ExamPaper.apk

Now, how do I call this script from within my controller method and pass the same parameter as ExamPaper.apk?

I tried require 'axml2xml.rb' but got some error pointing to this line of code Zip::ZipFile.foreach(ARGV[0]) do |f|. So basically, how do I make something like axml2xml.rb 'ExamPaper.apk' in my controller?

Answer 1

You have at least 3 options:

• exec(command)
• %x{ command }
• system(command)

They have different behaviors, so make sure to read this quicktip and/or the answer of this question to learn more about these commands.

In your case, the backticks or %x command is probably the best option.

value = `ruby axml2xml.rb ExamPaper.apk`
