Adding methods to Page from an extension

Ruby Apps Radiant CMS
1

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 methodparts’ 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

class Page < ActiveRecord::Base

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.

Page.send :include, NewPageMethods

That’s the magic I was looking for thanks.
