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.find(params[:id])
respond_to do |format|
    if @link.blank?
    format.html { redirect_to(root_url, :notice => 'Record not found') }
    else
    format.html { render :action => "index" }
    end
end
end

What I’ve been doing is putting this at the end of the method:

rescue ActiveRecord::RecordNotFound
  redirect_to root_url, :flash => { :error => "Record not found." }

Even better, put it as an around_filter for your controller:

around_filter :catch_not_found

private

def catch_not_found
  yield
rescue ActiveRecord::RecordNotFound
  redirect_to root_url, :flash => { :error => "Record not found." }
end
