Defining the class name of rails models when we’ve already named the file didn’t seem very DRY to me. So I wanted to find out if I could load files into a class named after the file (ie. Products.rb gets loaded in to Product class)
#!/usr/bin/env ruby # Loop over all ruby files in the classes directory Dir["classes/*.rb"].map do |file_name| # Save file name without extention or directories class_name = file_name[/[^\/]*(?=\.)/].to_sym # Execute the contents of the file inside a blank object class_object = Class.new class_object.instance_eval(File::read(file_name)) # Bind the class to the name at the highest level Kernel.const_set(class_name, class_object) end
This assumes that you have a bunch of ruby files inside a sub directory called ‘classes’ and all your ruby files have ‘.rb’ extension.
