• How can I use the match variable $1 following a substitution in Perl?

  - by justintime

  What is the cleanest way of picking up a match variable form a substitution in Perl I sometimes find myself writing s/(something)// ; my $x = $1 ; then I realize that if the s/ / / fails $1 might be carrying over a value from a previous match. So I try my $x = 'defaultvalue' ; if ( s/(something)// ) { $x = $1 ; } Is this the cleanest way of doing it?

• Is it possible to have variable find conditions for both the key and value?

  - by DarrenD

  I'm trying to pass in both the field and the value in a find call: @employee = Employee.find(:all, :conditions => [ '? = ?', params[:key], params[:value].to_i) The output is SELECT * FROM `employees` WHERE ('is_manager' = 1) Which returns no results, however when I try this directly in mysqsl using the same call without the '' around is_manager, it works fine. How do I convert my params[:key] value to a symbol so that the resulting SQL call looks like: SELECT * FROM `employees` WHERE (is_manager = 1) Thanks, D
