SQLSTATE[23000]：完整性约束冲突：1048列“阳台”不能为空。我不希望要求用户填写所有内容，只需要添加新的数据。请问如何在选择框和文件输入上显示现有数据？。有更好的方法吗？您可以将默认值传递给get请求。默认情况下，如果未填写该值，它将返回null。在您的情况下，您将需要一个空字符串：
$listing->balcony = $request->get('balcony', '');
您可以更改迁移以使字段为空 公共职能 { Schema:：创建“清单”，函数蓝图$Blueprint{ //……其他领域 $blueprint->string'balyone'->可为空； }; }
将nullable添加到迁移中的阳台字段和任何其他不需要值的字段中。我在列字段中包含了nullable，并创建了一个新列表，但当我尝试编辑时遇到此错误ErrorException Undefined offset:1did您是否再次迁移数据库架构？是的，我确实迁移了：fresh，当我创建一个新的列表时，它可以正常工作，但是当我现在尝试转到编辑页面时，我得到了一个错误我不能说任何话，除非看到编辑页面的代码和控制器代码我现在在上面发布了它，当我尝试转到edit.blade.php文件时，我得到一个ErrorException未定义的偏移量：1请告诉我有关此项的更多信息。可能您试图在不检查$阳台的值是否为空的情况下关联它。你发布的错误说明不了什么。
