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.
