Question

I have a module in /lib

Module Info
class Inf

  def getNum
    num = Array.new

    num.push(2,1)

  end

end

In the controller informations_controller I have ‘require Info’ and the follow code:

  def index
    @informations = Info::Inf.getNum().num

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @informations }
    end
  end

But it always gives the error

Routing Error

uninitialized constant Info

Since the router I have defined “root :to => ‘informations#index'” what could be missing?

Answer 1

it should be module not Module and also you should name file info.rb and also you should be sure lib is in auto_load paths inconfig/application.rb

config.autoload_paths += %W(#{config.root}/lib)

so it should be something like this lib/info.rb:

module Info
  class Inf
    ...
  end
end
