Quite a complicated subject for a post. 
Hope at least some of you have an idea about the topic of this post.
Activescaffold supports concept of an inline actionlink, which is basically just a list column as a hyperlink. Out of the box it is used for associations to have a one click path to associated records. Unfortunetly, it was nt supported for singular polymorphic associations and in one of my projects I was missing this feature. I had to implement a log feature using a database as store. Each log statement should include a reference to the source. source was a perfect candidate for a polymorphic association.
I just had to extend activescaffold to support singular polymorphic assocation inline actionlinks.
I ve prepared a simple example app including invoice and applog model for those of you who are interesting in trying out.
Setup Example Application
- Download: one_step_active_scaffold
- Download: polymorphici_blog.rb and rename it to model_setup.rb
- Execute following command: ruby one_step_activescaffold.rb polymorphic_app jquery
- cd polymorphic_app
- rails s
- http://localhost:3000/invoices
- Create new invoice with a log entry
- http://localhost:3000/app_logs

I’m trying to add paperclip with Polymorphic Association. It doesn’t appear as though the Polymorphic association is being detected by Active Scaffold? When I add the model association to ActiveScaffold it gives a Template::Error (Could not find ImagesController or ImageController)
For Example:
class Image true
has_attached_file :image
end
class User :imageable
end
I don’t know if the best way would be to set these up as some type of nested or embedded scaffold instead?

Do you have an Images Controller

That appears to be exactly what I needed to do. I was making this way more complicated than it needed to be.
Thanks!
