Problem mit .Install -Datei

Question

Ich habe versucht, das Schema für eine Tabelle wie unten angegeben zu schreiben, aber es hat nicht funktioniert. Lassen Sie mich wissen, was der Fehler ist, den ich gemacht habe.

<?php

Answer 1

Ich habe zwei automatische Spalten im Schema verwendet (r_id & st); Das ist der Fehler.

Answer 2

Das sparsh_module_write_record() Die Funktion, die Sie geschrieben haben, scheint eine reduzierte Version von Drupal_Write_Record () Dies betrachtet den Fall, in dem die Zeile geschrieben wird, nicht in der Datenbanktabelle vorhanden.
Wenn der Code versucht, eine Zeile zu speichern, die den gleichen Wert der von einer anderen Zeile verwendeten Primärschlüssel verwendet, erhalten Sie einen Fehler.
