我有一个包含许多数组的数组，我希望使用saveAll或saveMany保存数据。但是，由于我无法更改的因素，并非所有数组实际上都包含任何数据。在转储中，您可以看到，只有前两个数组被填充。
使用saveAll或saveMany保存此数组时，收到以下错误：Integrity constraint violation: 1048 Column 'productinfo_id' cannot be null。
使用saveAll或saveMany保存数组时，如何避免此错误？

答案 0 :(得分：1)
在保存数组之前，我建议循环它并过滤空数组。例如：
$originalArray = #Your Data;
$saveArray = array();
foreach($originalArray as $item) {
if(!empty($item['productinfo_id'])) {
$saveArray[] = $item;
}
}
然后，您可以将新数组提供给saveAll方法。

完整性约束违规：1048列'productinfo_id'不能为空
我假设你明白这意味着什么？您需要将值传递到此字段，不能保存空行productinfo_id的表行。我认为这应该被称为product_info_id。
因此，不像Lars所建议的那样过滤空数组，我首先要问的问题是：为什么它们会出现？我会避免这种情况。
避免在SQL错误发生时遇到的硬错误的正确解决方案是在模型中to use validation，以确保根本无法保存记录并且在空{{}上验证失败1}}。这将确保一种优雅而有意义的方式来处理这个问题。
除此之外，您还可以过滤掉beforeSave（）回调中的“空”关联记录。但这是不是的主要修复方法，验证是。
