毛毛雨错误：列“created_at”无法自动转换为没有时区的时间戳

Question

这是我的 schema.ts 文件

export const messages = pgTable("messages", {
  id: serial("id").primaryKey(),
  chatId: integer("chat_id")
    .references(() => chats.id)
    .notNull(),
  content: text("content").notNull(),
  createdAt: timestamp("created_at").notNull().defaultNow(),
  role: userSystemEnum("role").notNull(),
});

它抛出错误为：

error: column "created_at" cannot be cast automatically to type timestamp without time zone

}

对于也显示相同错误的角色：

export const userSystemEnum = pgEnum("user_system_enum", ["system", "user"]);
hint: 'You might need to specify "USING role::user_system_enum".'

我该如何解决这个问题？

我认为你需要重组createdAt，我不太确定这里出了什么问题。但也许这会起作用：

  createdAt: timestamp("created_at").defaultNow().notNull(),
