Question

在数据库中存储数据时出错。.

我将数据存储在数据库中，但是它给出了错误，表明违反完整性约束：1048列'lawyer_id'不能为空”

public function lawyersDiplomaInfo(Request $request){
            $dipInstitution = $request->get('diploma_name');
            $dipYear =  $request->get('diploma_year');
            $all_params = $request->keys();
            $total_dipFile = preg_grep("/^dip_file_.*/", $all_params);
            if($dipInstitution != null && $dipYear != null){
                $lawyer = new Lawyer();
                $data = new LawyerDiploma();
                $data->lawyer_id = $lawyer->id;
                $data->diploma_institution = $dipInstitution;
                $data->year = $dipYear;
                $data->created_at = Carbon::now();
                $data->updated_at = Carbon::now();
                $data->save();
            }
            for($i = 0; $i < count($total_dipFile); $i++){
                if($request->file('dip_file_'.$i) != null){
                    $filename = $request->file('dip_file_'.$i)->store('diplomafile');
                    $files = new DiplomaFile();
                    $files->diploma_id = $data->id;
                    $files->file = $filename;
                    $files->save();
                }
            }
        return ['message' => 'Data Added'];
    }

在 $ data-> lawyer_id = $ lawyer-> id; 行中，它给出了错误。

Answer 1

在$ data-> lawyer_id = $ lawyer-> id的两行中创建$ lawyer（$ lawyer = new Lawyer（）），因此需要将$ lawyer参数设置为$ data。
