• Are there any alternative to the header(); function ?

  - by Simon

  The thing is, I have a log-in page. And, when user enters Username & Password, they must be re-directed to success/failure page. Now, I have placed a "header('location:welcome.php');" after mysql rows are returned. But, it is giving me Header already sent errors, and I don't know much about PHP to do anything about it, let alone understand why it is happening. So, how to you transfer a user to another page after log-in data is verified? Same problem is happening with register, post, comment and search functions in my site.

• What is Rails way to DRY up the controller pattern of verifying :id is for a valid object (else redirect to error page)

  - by jpwynn

  One of my controllers has close to 100 methods (eg routes) and nearly every one starts out the same code to redirect to an error page if the id param is invalid, followed by a similar check if the user that id doesn't belong in the user's account: def something @foo = Foo.find_by_guid(params[:id]) unless @foo @msg ||= { :title => 'No such page!', :desc => "There is no such page!" } render :action => "error" and return end unless @foo.owner_id == current_user.id @msg ||= { :title => 'Really?', :desc => "There is no such page." } render :action => "error" and return end What is the best way to DRY up that sort of page id and owner id validation, given the code is doing a render ... and return? What I don't want to do at this point is offload it to a blackbox roles and permissions library like CanCan... my goal is simply to have the in-app code to handle this be as clean as possible.

• Is it faster to compute values in a query, call a Scalar Function (decimal(28,2) datatype) 4 times,

  - by Pulsehead

  I have a handful of queries I need to write in SQL Server 2005. Each Query will be calculating 4 unit cost values based on a handful of (up to 11) fields. Any time I want 1 of these 4 unit cost values, I'll want all 4. Which is quicker? Computing in the SQL Query ((a+b+c+d+e+f+g+h+i)/(j+k)), calling ComputeScalarUnitCost(datapoint.ID) 4 times, or joining to ComputeUnitCostTable(datapoint.ID) one time?

  That is the question. What I want to accomplish is something similar to the following Java code: class A { } class B extends A { } public class Tests { public static void main(String [] args) { ArrayList<? extends A> lists = new ArrayList<B>(); } } (in which B extends A means B inherits from A) Is it possible at all? Thanks
