conditional logic when dealing with nil

I had a piece of code in an rjs file that checked to see if a variable existed:

if @product   ... do something here ... end

that worked fine, but then I also need to check and see if a column is empty or nil, so i changed it to this:

if @product || !@product.price.blank?   ... do something here ... end

this always gives me "You have a nil object when you didn't expect it!" errors

is there a better way of doing this without nesting if statements inside eachother?

Try this: if @product && @product.price.blank?   # Do something here end

In the code below, if @product is nil, the first condition is false so the second condition is evaluated. @product.price will fail when @product is nil.
