Please show us the code that you're using. Without code, this issue is

Thanks for your response. I've managed to get this part working and can
now use the extension db table in the rails console.

I need to use the rails console to add rows though, as per the tutorial, because there's not yet any views created to add data.

Now I don't see how to add views. The tutorial makes much of Deface but I don't understand which 'hook' I'm supposed to overwrite as my extension
should produce a view separate from the store. It's not a products page as such.

The routes file is ok, I just see a blank page when visiting the required url.
How do I create view such that they will follow the application layout but contain their own content?

4. run rake db:migrate from your application

That should create the table you require.

Any time you want to add rows to your table you should do so from your

Hi all,

Can anyone please tell me how I create an extension that requires it's
own db table? Based on the extension tutorial at
http://guides.spreecommerce.**com/developer/extensions_**tutorial.html<http://guides.spreecommerce.com/developer/extensions_tutorial.html>it looks like I should create the migration in the spree store and it will
be run when I run the install generator. However, I don't see my new
'offers' table in the db and my site page gives the following error:

NameError in Spree::HomeController#offers

uninitialized constant Spree::Offer

Also - I need to add a row to this table but do I run rails console from
the store directory, or from the extension directory? The tutorial is
