迁移:
Schema::create('students_detail', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('student_id');
$table->integer('lessons')->nullable();
$table->string('tests',200)->nullable();
$table->timestamps();
$table->foreign('student_id')->references('id')->on('students')
});
控制器:
public function update(Request $request, StudentsDetail $studentsDetail)
{
$student_id= $request->input('student_id');
$studentsDetail->update($request->except('student_id'));
$studentsDetail->save();
return redirect()->back();
}
我尝试将mysql strict设置为false,但不能解决我的错误,注意:我不能使列'student_id'
为空,因为它是外键,所以在更新此错误时会出现吗?我不知道如何摆脱它!

在模型文件保护的$ fillable数组中添加student_id,例如:
protected $fillable = ['student_id'];
在控制器上保存代码:
$attributes = $request->all(); // print_r($request->all()) this request and check have you got student_id fields?
$studentsDetail->update($attributes);
return redirect()->back();

您必须将其传递给更新方法:
public function update(Request $request, StudentsDetail $studentsDetail)
{
$studentsDetail->update($request->all());
$studentsDetail->save();
return redirect()->back();
}
