Laravel 5.4 SQLSTATE [23000]: Integrität Einschränkung Verletzung: 1062 doppelten Eintrag '0' Live-Website

Question

Ich habe eine Produkttabellen und Product_Galleries Tabelle, die miteinander verbunden sind durch viele Beziehung hat, erscheint das Problem, wenn ich versuche, ein neues hinzuzufügen Produkt vom Back-End, PS: Der Fehler erscheint nur in meiner Live-Website, in meiner lokalen Umgebung funktioniert das Back-End gut und kann ich so viele Produkte hinzufügen, wie ich möchte.

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY' (SQL: insert into `products` (`product_name`, `product_description`, `product_preview`, `category_id`, `color_id`, `size_id`, `material_id`, `fantasia_id`, `slug`, `updated_at`, `created_at`) values (Test 2, , 1499770479-Petronius0039.jpg, 1, , , , , test-2, 2017-07-11 10:54:39, 2017-07-11 10:54:39))

Answer 1

Es scheint, dass increments() nicht für Sie arbeitet.

Sie können versuchen, unsignedInteger(), da es eine Spalte mit Int Typ erstellt, und können Sie auch mit auto_increment Constraint erstellen. Es ist das gleiche wie increments(), gerade so herum. Sie sollten den Code wie folgt schreiben.

$table->unsignedInteger('id', true); 

Hier nimmt unsignedInteger() erste Argument als string für Name der Spalte, und 2. Argument als boolean für auto_increment. Probieren Sie es aus und lassen Sie uns wissen, ob es funktioniert.
