A note object is always attached to another database entity. Which one |
|
| 63 |
is determined by the columns C<trans_module> and C<trans_id>. This |
|
| 64 |
function looks at both, retrieves the corresponding object from the |
|
| 65 |
database and returns it. |
|
| 66 |
|
|
| 67 |
Currently the following three types are supported: |
|
| 68 |
|
|
| 69 |
=over 2 |
|
| 70 |
|
|
| 71 |
=item * C<SL::DB::FollowUp> for C<trans_module == 'fu'> |
|
| 72 |
|
|
| 73 |
=item * C<SL::DB::Customer> or C<SL::DB::Vendor> for C<trans_module == |
|
| 74 |
'ct'> (which class is used depends on the value of C<trans_id>; |
|
| 75 |
customers are looked up first) |
|
| 76 |
|
|
| 77 |
=back |
|
| 78 |
|
|
| 79 |
The method returns C<undef> in three cases: if no C<trans_id> or no |
|
| 80 |
C<trans_module> has been assigned yet; if C<trans_module> is unknown; |
|
| 81 |
if the referenced object doesn't exist. |
|
| 82 |
|
|
| 83 |
This method is a getter only, not a setter. |

SL::DB::Note: Funktion trans_object zum Auslesen des referenzierten Objekts
Ein Note-Objekt hängt immer an einem anderen Datenbankobject, das über
trans_module+trans_id referenziert wird. Diese Funktion entscheidet
anhand von trans_module, welche Rose-Klasse zu instantiieren ist, holt
das entsprechende Objekt aus der Datenbank und gibt es zurück.
Auch bei polymorphen Objekten wie Kunden/Lieferanten (für trans_module == ct) wird das richtige getan.
