I’m trying to create an editable table by rendering a partial containing  
a form.

In the index:

 \<%= render :partial =\> 'product\_edit', :collection =\> @products %\>

In the partial:

\<% form\_for :product do |f| %\>

 \<%= f.text\_field :name %\> \<%= f.select :in\_stock, [['YES','true'],['NO','false']] %\> \<% end %\>

I’m getting an error ‘undefined local variable or method `product`…’

What am I doing wrong?

The name of the local variable is the name of the partial, which is  
product\_edit  
in this case.
