Hey,

I want to pass this class object in the var “item”  
\<%= render :partial =\> ‘/shared/form\_system\_attributes’, :locals =\> {  
:item =\> @album, :edit =\> true, :publish =\> true } -%\>

this can be (these are objects):  
:item =\> @album  
:item =\> @product  
:item =\> @album\_category

In \_form\_system\_attributes.rhtml I do

\<%= check\_box item.class.to\_s.downcase, “publish”, {:size =\> 1} %\>

this gives:  
  
  
 ==\> this in incorrect: it should be  
album\_category

Is there anything other than item.class for getting the classname with  
underscores, like the model filename.

Thx

N.

Try the underscord method (ie “CamelCase”.underscore gives “camel\_case”)
