Rails - Mar 2006 - How to retrieve attribute values of objects?????

Hi,

 I am writing following line in my code:-
================@product1=Product.find(:all, :conditions => ["id = ?
",
params[:product][''product_id''+count.to_s]])
print @product1.inspect
==========================
So I am getting on console following output.
=========================[#<Product:0x3cd61c8
@attributes={"demand"=>nil, "name"=>"Part2",
"quantity"=>"4", "id"=>"3",
"unit_price"=>"1.000"}>]
=========================
But when I am writing "print @product1.name" instead of "print 
@product1.inspect" in my code for displaying just name on console I m 
getting following error:-
========================undefined method `name'' for
#<Array:0x3bcb720>
=========================Why I m getting this error? & what should I write
with "print" method in
above code to get value of name attribute associated with "@product1" 
object?

Thanx in advance.

Product.find with :all returns an array of Products.

If you''re only expecting a single row back, use:

Product.find with :first

and your code will work otherwise as-is.

Notice the [] around the .inspect output

With the existing code your could use:

@product1[0].name, or much better, @product1.first.name
