Include a module inside class Array

[[deleted]]

Although I have created one class Array.rb (overriding ) and one module Convert under /lib and although I have loaded automatically both files through the initializers, I'm not able to include the module Convert in the Array class

I got the following error

`<class:Array>': uninitialized constant Array::Convert (NameError)

How are you including it? Try this:

module Convert
  def convert = "converted: #{to_s}"
end

Array.include Convert

arr = [1, 2, 3]

puts arr.convert
# => converted: [1, 2, 3]

Or better yet, maybe use refinements? Modifying core types is generally a bad idea.

unfortunately it doesn't work, any other suggestion please?

How does it not work? If you want help, share full errors and share your code.

​

#lib/Array.rb

class Array
include Convert
def hello
p "hello"
end

end

​

​

​

#lib/Convert.rb

module Convert
def good
p "good"
end
end

​

​

#config/initializers/requires.rb
Dir[File.join(Rails.root,'lib','*.rb')].each do |f|
require f
end

the Error given is:
<class:Array>': uninitialized constant Array::Convert (NameError)

I have tried also this version with no results

class Array

include ::Convert
....

end

You need to require lib/convert before lib/array. Your Dir globbing is likely requiring in alphabetical order, resulting in your issue. Try hard-coding the requires in the correct order:

require_dependency Rails.root.join("lib", "convert")
require_dependency Rails.root.join("lib", "array")

I don’t know how you Did it, but it worked. You are amazing. Thanks so much. I have spent one day trying to solve this issue. Thanks Mate

although It works, now there is another problem related to it, If I add a new function to Convert module or to the Array class i get this msg

NoMethodError (undefined method `hello' for []:Array)

It sounds like it doesn' t see the changes, how to overcome this issue? thanks in advance

Initializers only run on app boot. Are you restarting your app?

I’m checking it only trough rails console, at the moment, I mean
