Laravel应用程序未保存数据且未显示任何错误

Question

我正在使用控制器存储方法来保存数据，我已经安装了模型，视图和控制器。我正在使用Laravel资源路由，并打算使用控制器执行CRUD操作。但是，似乎没有任何效果。

这是Controller的保存方法

public function store(Request $request)
{
    //

    $request->validate([
        'adm'=>'required|unique:student',  
        'fullname'=>'required|alpha', 
        'dept'=>'required|alpha', 
        'course'=>'required|alpha',  
        'level'=>'required|alpha',  
        'feyear'=>'required|numeric', 
        'feser'=>'required|alpha', 
        'idnum'=>'unique:student|required|numeric|max:8', 
        'current_address'=>'required',  
        'permanent_address'=>'required',
        'email'=>'unique:student|required|email',
        'mobile'=>'unique:student|required|numeric', 
        'occupation'=>'nullable', 
        'occupation_place'=>'nullable',
        'otherphone'=>'nullable:numeric|max:13', 
        'nextofkin'=>'nullable|alpha', 
        'nextofkinadd'=>'required', 
        'nextofkinphone'=>'required|numeric', 
        'placeofworkadd'=>'nullable', 
        'supervisoradd'=>'nullable'
    ]);


    $std = new Student([

       'adm'=> $request->get('adm'),  
       'fullname'=> $request->get('fullname'), 
       'dept'=> $request->get('dept'), 
       'course'=> $request->get('course'),  
       'level'=> $request->get('level'),  
       'feyear'=> $request->get('feyear'), 
       'feser'=> $request->get('feser'), 
       'idnum'=> $request->get('idnum'), 
       'current_address'=> $request->get('current_address'),  
       'permanent_address'=> $request->get('permanent_address'),
       'email'=> $request->get('email'),
       'mobile'=> $request->get('mobile'), 
       'occupation'=> $request->get('occupation'), 
       'occupation_place'=> $request->get('occupation_place'),
       'otherphone'=> $request->get('otherphone'), 
       'nextofkin'=> $request->get('nextofkin'), 
       'nextofkinadd'=> $request->get('nextofkinadd'), 
       'nextofkinphone'=> $request->get('nextofkinphone'), 
       'placeofworkadd'=> $request->get('placeofworkadd'), 
       'supervisoradd'=> $request->get('supervisoradd') 
   ]);

    $std->save();
    return redirect('/')->with('success', 'You have been added as an Student');
}

我的模特

class Student extends Model
{
    protected $fillable = [
        'adm',  
        'fullname', 
        'dept', 
        'course',  
        'level',  
        'feyear', 
        'feser', 
        'idnum', 
        'current_address',  
        'permanent_address',
        'email',
        'mobile', 
        'occupation', 
        'occupation_place',
        'otherphone', 
        'nextofkin', 
        'nextofkinadd', 
        'nextofkinphone', 
        'placeofworkadd', 
        'supervisoradd'
    ];
}

Answer 1

您是否已检查收到的请求数据？尝试转储它，并检查其是否正确dd($request->all())

还要检查您的日志，laravel.log，php-errors.log等。

此外，您的验证者还应返回经过验证的数据，例如：

$validatedData = $request->validate([
    'adm'=>'required|unique:student',  
    'fullname'=>'required|alpha',
    etc....
]);

然后，如果所有字段都在您的 fillable 数组中，则可以执行以下操作：Student::create($validatedData)

无论如何，我建议您使用Form Requests进行验证，这样您的控制器就不会那么肿。

Answer 2

也许，您可以尝试使用fill方法来更具体

尝试：

$std = new Student;
$std->fill($request->all());
$std->save();

Answer 3

尝试做

$std = Student::create([

       'adm'=> $request->get('adm'),  
       'fullname'=> $request->get('fullname'), 
       'dept'=> $request->get('dept'), 
       'course'=> $request->get('course'),  
       'level'=> $request->get('level'),  
       'feyear'=> $request->get('feyear'), 
       'feser'=> $request->get('feser'), 
       'idnum'=> $request->get('idnum'), 
       'current_address'=> $request->get('current_address'),  
       'permanent_address'=> $request->get('permanent_address'),
       'email'=> $request->get('email'),
       'mobile'=> $request->get('mobile'), 
       'occupation'=> $request->get('occupation'), 
       'occupation_place'=> $request->get('occupation_place'),
       'otherphone'=> $request->get('otherphone'), 
       'nextofkin'=> $request->get('nextofkin'), 
       'nextofkinadd'=> $request->get('nextofkinadd'), 
       'nextofkinphone'=> $request->get('nextofkinphone'), 
       'placeofworkadd'=> $request->get('placeofworkadd'), 
       'supervisoradd'=> $request->get('supervisoradd') 
   ]);

或者如果您的$ request字段与可填充字段相同则更简单

$input=$request->all();
$std = Student::create($input);
