About scaffold mean

Rails
1

Hello All!

I’m novice at ROR. Would you like to explain what mean such constuction
in
Ruby.

1: class DemoController < ActionController::Base
2: scaffold :item
3: end

Is 2th line calling of method ‘scaffold’? If it is so, when it called?
For
all instances of class, or only for class?
I watch sources of ActionController, but don’t understand completely.

Thanks.

Hi Alex,

In simple terms, that line (#2) tells Rails to create the basic pages
for the object/model called ‘item’. That will allow the DemoController
to create simple dynamic pages to: create, retrieve, update and delete
objects of the type ‘item’

Hope this helps,
mohit.

That would be ‘2nd’ line. :-s English - it’s weird.

It’s calling a class method ‘scaffold’, which as far as I know generates
the necessary instance methods in the DemoController class.

If it is so, when it called?

The first time the DemoController class definition is executed.

Yeah, it baffled me the first time I saw it too.
