我有一些用于插入数据的输入。当我填满所有输入后,它便能正常工作,但是当我尝试插入空输入时,它给了我这个错误违反完整性约束:1048列'monday'不能为空
现在,我也请求此表格并提供所需的所有内容,并尝试显示错误,但那也不起作用。我不知道我的代码有什么问题。下面是我的代码。查看它:)
//控制器
public function store(Request $request)
{
$timetable = $request->all();
Timetable::create($timetable);
return redirect()->back();
}
//查看
<div class="ml-4 mr-4 py-3">
{!! Form::open(['method'=>'POST', 'action'=>'TimetableController@store', 'class' => 'mb-5']) !!}
<div class="form-group">
{!! Form::label('class_id', 'Class', ['class'=>'control-label display-4']) !!}
{!! Form::select('class_id', [''=>'Choose Class'] + $classes, null, ['class'=>'form-control']) !!}

答案 0 :(得分:1)
嗯,错误很明显。
返回迁移,找到monday
列,然后添加->nullable()
。
示例:
$table->string('monday')->nullable();
