Replace

What is the easiest way to replace record in database?

Better that this:

@old = Order.find(5) @new = Order.find(90)

@old.x = @new.x @old.y = @new.y @old.z = @new.z @old.w = @new.w @old.p = @new.p @old.r = @new.r ...

@old.save

So now @old = @new except @old.id and @old.created_at

2

@old.attributes = @new.attributes

or you can even get rid of @new completely

@old.attributes = Order.find(90).attributes

@old.save
