与与当前操作无关的字段相关的理论投掷错误

Question

我目前正在使用类似于imgur的应用，并且收到以下错误

[使用参数[1，1]执行'INSERT INTO user_gallery_views（gallery_id，user_id）VALUES（？，？）'时发生异常：SQLSTATE [23000]：违反完整性约束：19 UNIQUE约束失败：user_gallery_views.gallery_id，user_gallery_views.user_id

[在saved中调用将对象添加为users collection的路径时发生

我不明白的是，为什么甚至在/image/{id}/save中都没有使用user_galler_views时，错误会引起关注？

我确定没有看到任何东西，但什至都不知道，所以我充满希望您能帮助我

Answer 1

似乎您将实体存储到错误的数组。

public function addSave(User $save): self
{
    if (!$this->saves->contains($save)) {
        $this->views[] = $save;
    }

    return $this;
}
