Create a file in a specified directory

Question

How can I create a new file in a specific directory. I created this class:

class FileManager

    def initialize()

    end

    def createFile(name,extension)
        return File.new(name <<"."<<extension, "w+")
    end
end

I would like to specify a directory (path) where to create the file. If this one doesn't exist, he will be created. So do I have to use fileutils as shown here just after file creation or can I specify directly in the creation the place where create the file?

Thanks

The following code checks that the directory you've passed in exists (pulling the directory from the path using File.dirname), and creates it if it does not. It then creates the file as you did before.

require 'fileutils'

def create_file(path, extension)
  dir = File.dirname(path)

  unless File.directory?(dir)
    FileUtils.mkdir_p(dir)
  end

  path << ".#{extension}"
  File.new(path, 'w')
end
