Ruby FileUtils.mkdir_p is only creating parent directories

I have a controller in Rails, with an action that is meant to create a new directory.

This action should create the directory "/public/graph_templates/aaa/test". However, it leaves off the final directory "test". Why is this only creating parent directories?

  def create_temporary_template
    dir = File.dirname("#{Rails.root}/public/graph_templates/aaa/test")
    FileUtils.mkdir_p dir
  end

Solution

  • Because you use dir = File.dirname("#{Rails.root}/public/graph_templates/aaa/test"),

    then the dir is "#{Rails.root}/public/graph_templates/aaa".

    You could just pass the path to FileUtils.mkdir_p.

      def create_temporary_template
    dir = "#{Rails.root}/public/graph_templates/aaa/test"
    FileUtils.mkdir_p dir
  end
