Rails how to redirect if record is not found

Question

I am trying to redirect if the record is not found. The page is not redirect and I get the error record not found.

My controller:

def index
@link = Link.         


        

Answer 1

error is generated by Link.find - it raises exception if object was not found

you can simplify your code quite a bit:

def index
  @link = Link.find_by_id(params[:id])

  redirect_to(root_url, :notice => 'Record not found') unless @link

  respond_to do |format|
    format.html
  end
end
