我正在嘗試清理我的控制器。我有很多表單字段，所以我想使用觀察者為與主模型有關(guān)系的其他模型插入我已經(jīng)成功地將請(qǐng)求插入到控制器中的數(shù)據(jù)庫(kù)中，但它似乎又長(zhǎng)又重?？聪旅娴拇afunction insert(Request $request){ $bankStatementName = time().'.'.request()->bankStatement->getClientOriginalExtension();request()->bankStatement->move(public_path('bankStatement'), $bankStatementName);$identityName = time().'.'.request()->identity->getClientOriginalExtension();request()->identity->move(public_path('identity'), $identityName); $passportName = time().'.'.request()->passport->getClientOriginalExtension();request()->passport->move(public_path('passport'), $passportName); $customer = Customer::find(Auth::user()->id); $relations = new Customer_relationship([                      'kinName' => $request->kinName,                      'kinGender' => $request->kinGender,                      'kinEmail' => $request->kinEmail,                      'kinRelation' => $request->kinRelation,                      'kinAddress' =>  $request->kinAddress                  ]); $company = new Customer_company([                'compName' => $request->compName,                'compEmail' => $request->compEmail,                'compPhone' => $request->compPhone,                'compAddress' => $request->compAddress             ]); $bank = new Customer_bank([             'accNumber' => $request->accNumber,             'bankName' => $request->bankName,             'accName' => $request->accName         ]); $document = new Customer_document([        'identity' => $identityName,        'bankStatement' => $bankStatementName,        'passport' => $passportName    ]); $customer->relation()->save($relations); $customer->company()->save($company); $customer->bank()->save($bank); $customer->document()->save($document);}那么如何從觀察者的更新功能訪問(wèn)表單請(qǐng)求字段以進(jìn)行控制器清理
