Hey I feel like I’m missing something obvious,

I created an extension that adds some columns to the pages table, and  
now I want to add some methods to the Page class.

I put this at the bottom of my Extension class

class Page \< ActiveRecord::Base

def test\_new\_method  
“hi”  
end

end

And now I’m getting errors like:

undefined method `children' for #<Page:0x2280638> undefined method`parts’ for #Page:0x2280638

Which leads me to believe that my version of Page is being loaded, and  
the original version is not.

How do I get them both to load? what’s really going on here?

Also, can somebody tell why “logger” is not defined from my Extension  
class  
How can I access the logger?

thanks,  
Jacob

Should be:

YourPageClassName \< Page

No, I don’t want to subclass page, I want to add methods to all pages.

I could directly edit page.rb but I’d like to limit my edits to remain  
within the folder for my extension.

I am redefining page in the app/models directory of my extension

and in my extension definition I can explicitly load this verison of  
page

like this:

load  
“#{RADIANT\_ROOT}/vendor/extensions/page\_attributes/app/models/page.rb”

UGLY!!!

but that works…  
Shouldn’t it just get loaded by default. What do I do to fix this?

It might be better to put your added methods in a module and include  
them in Page inside the activate method of your extension, like so:

module NewPageMethods  
def foo  
“bar”  
end  
end

# in your extension

def activate  
Page.send :include, NewPageMethods  
# …  
end

Put your methods in a module and mix them into page in your extension’s  
activate method.
