All,

I have a schema which contains two columns called “category\_id” and  
“data\_id”, and “category” and “data” are two other different tables in  
the same database. When I use “Scaffold” to generate the view and  
controller I found that in “\_form.rhtml” there are no input field for  
“category\_id” and “data\_id”. It seems like scaffold skipped them for  
some reason.

Is it what it is suppose to be?

Thanks,  
Yingqi

Yup, which is fairly obvious if you look at the actually generated  
code and look up the content\_columns method \<http://  
[ActiveRecord::Base](http://api.rubyonrails.org/classes/ActiveRecord/Base.html#M001020)\>.
