How to retrieve attribute values of objects?


#1

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
