Laravel - Maatwebsite Excel 导入仅存储在存储中但不存储在数据库中

Laravel - Maatwebsite Excel import stored in storage only but not in DB

我正在使用 Laravel-8 端点和 Maatwebsite-3.1 包导入 Excel 文件。

我这样做的方式是，上传的 Excel 文件将首先进入存储 (storage/file_imports/student_imports)。然后 Laravel 从那里获取它，使用 Maatwebsites 通过 StudentImport 将其存储到数据库 table。

学生导入：

{
    return [
        '1.in' => 'Custom message for :attribute.',
        'nim.unique' => 'Custom message',
    ];
}
}

控制器：

public function importStudent(Request $request)
{
try {
    $user = Auth::user()->id;
    $validator = Validator::make($request->all(), [
        'document' => 'file|mimes:xlsx|max:10000',
    ]);
    if($validator->fails()) {
        return $this->error($validator->errors(), 401);
    } else {
        $check = User::where('id', $user)->pluck('id');
        if($check[0] !== null || $check[0] !== undefined) {

            $file = $request->file('document');
            $file->move(public_path('storage/file_imports/student_imports'), $file->getClientOriginalName());
            Excel::import(new StudentImport, public_path('storage/file_imports/student_imports/' . $file->getClientOriginalName() ));
            return $this->success('Students Successfully Imported.', [
                'file'         => $file
            ]);
        } else {
            return $this->error('Not allowed', 401);
        }
    }
    } catch(\Exception $e) {
        return $this->error($e->getMessage());
    }
}

如我之前所述，它将首先将 Excel 文件存储到：

storage/file_imports/student_imports

然后从那里选择它并存储在数据库中。

这段代码在上面的控制器中。

文件存储在

public/storage/file_imports/student_imports

符合预期，但在数据库中找不到任何内容。是的，它显示成功，没有错误。

可能是什么问题，我该如何解决？

谢谢

model 方法 StudentImport class must return new instance of Eloquent model.

您不应该通过您的模型在此处调用创建或更新方法。
