Hey all,
In app/builders, I have a file called table_builder.rb. In the constructor method of my TableBuilder class, I call an instance method called assign_attributes which takes a hash and converts the key/value pairs into instance methods.
The assign_attributes method is declared in the following directory: lib/core_extensions
In that directory I have a file called core.rb which contains the class Object and the instance method assign_attributes is a method of Object class (and so when you declare a class, since a class is an object, all classes will inherit from the Object class since Object is the root class of all classes):
class Object def assign_attributes(attributes) attributes.each_pair { |k,v| send("#{k}=", v) if respond_to?("#{k}=") } if attributes end end
Hence, this instance method should be available to all classes, including my TableBuilder class since TableBuilder implicitly inherits from Object. The problem is I believe the Object class is never found.
In order to make it be found, in my initializers directory, I create a file called ext.rb and add the following line:
require "core_extensions/core" Dir[File.join(Rails.root, "lib", "core_extensions", "*.rb")].each {|l| require l }
This should require that core.rb script in all of the other scripts, including builders/table_builder.rb
But when I load the page, I am greeted with an undefined method exception:
undefined method `assign_attributes' for #<TableBuilder:0x00000100fc7708>
Thanks for response.
