我正在使用laravel 5.5来更新条目.问题是在更改主键'id'之后,这是一个默认的默认pk为'project_id'.添加项目工作正常,但更新项目不能正常工作.这是我得到的错误.

方法保存不存在.

这是我的模特.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Project extends Model
{
   protected $primaryKey = 'project_id';
    public function user()
    {
        return $this->belongsTo(User::class);
    }
    public function tasks()
    {
        return $this->hasMany(Task::class);
    }
}

这是我的控制器功能.

public function editProject($id){

        $project = Project::where('project_id', $id)->firstOrFail();
        $data = ["project_info" => $project];
        return view('projects.edit')->with($data);
    }
    public function updateProject(Request $request){
        $data = $request->all();
        $validator = Validator::make($data, [
            'project_title' => 'required',
            'project_description' => 'required',
            'project_start_date' => 'required',
            'project_end_date' => 'required',
            'project_status' => 'required',
        ]);

        $response = [];

        if …

我有以下表格，其中列出了问题并有一个答案字段。api 循环列出的问题，所有问题都需要具有相同的字段名称。一切正常，问题是我无法提交除最后一个之外的所有表单值。有没有办法为多个字段使用表单控件名称。
