Why do I get "undefined method 'insertsaying' for main:Object"?

Question

I'm using DataMapper to create rows in MySQL. To make a new row in my "Ryne" table, I do:

a = {:saying, "Ppffftt..!"}
Ryne.create a

So I said to myself, "Since I use this all the time, why not make a more 'slick' method which does this...":

def insertsaying(x)
    h = {:saying, x}
    Ryne.create h 
end

However, my output in IRB for insert saying("Pffffft..") is:

NoMethodError: undefined method `insertsaying' for main:Object
from (irb):2

The method itself is defined in a .rb file which I am currently requiring in IRB. Aside from the DataMapper.setup call, the rest of the .rb file looks like this:

DataMapper::Logger.new($stdout, :debug)
dm = DataMapper.setup :default, "mysql://php:phpwebsite@xxx.xxx.xxx.xxx/visit"
dm.resource_naming_convention = DataMapper::NamingConventions::Resource::Underscored


class Ryne
    include DataMapper::Resource
    is :reflective
    reflect /.*/
end

DataMapper.auto_upgrade!

def insertsaying(x)
    h = {:saying, x}
    Ryne.create h 
end

I'm not sure what I am doing wrong however I believe it is a scope issue. Do I need to require something else in the method?

Are you doing all this in IRB? Is method defined also in IRB? — Sergio Tulentsev, Mar 29 '13 at 15:05
No the method is defined in a .rb script I require which includes the table mapping and DataMapper.setup calls. — Sean Larkin, Mar 29 '13 at 15:07
I updated the original question to show the rest of the .rb file for your viewing pleasure. — Sean Larkin, Mar 29 '13 at 15:11
don't make naked functions like that. Wrap them in a class. Ruby is pro-OO language :) — Sergio Tulentsev, Mar 29 '13 at 15:14
More or less what I'm wanting to know is why I'm getting the undefined method error...I thought that naked methods or functions are defined under class Object. — Sean Larkin, Mar 29 '13 at 15:30
They are defined in Object, but I think @SergioTulentsev is telling you to move `insertsaying` inside `Ryne`, because that is where it should be logically. — the Tin Man, Mar 29 '13 at 16:12
