如何使用 Laravel 更新多条记录？

Question

我想更新与项目相关的多条记录，并且我已经制定了在控制器中存储数据的逻辑；它完美地添加了多条记录，但我不知道该怎么做。

我还想更新数据库中已经存在的多条记录。

     public function project()
   {
       return $this->hasOne('App\Project','project_id',id)
   }

模型项目

     public function issue()
   {
       return $this->hasMany('App\Issue','id','project_id')
   }

public function issuesUpdate(Request $request, Project $project)
   {
       $issues =Issue::where('project_id',$project->id)->get();            

        //for add new record 
        foreach($request->date  as  $key2 => $val){
            $issue               =  new Issue;
            $issue->date         =  $val;
            $issue->issue        =  $request->issue[$key2];
            $issue->project_id   =  $project->id;
            $issue->save();
        }
         return redirect()->route('project');
}

路线

  Route::post('/projects/{project}/issues/update', "ProjectController@issuesUpdate")- 
  >name('project.issues.update');

首先改变你的数据格式

  "date": [
    "2020-07-06",
    "2020-07-22",
    "2020-07-11"
  ],
  "issue": [
    "edit issue",
    "delete issue on web",
    "update issue on cms"
  ]

到

[
  ["date"=>"2020-07-06","issue"=>"edit issue"],
  ["date"=>"2020-07-22","issue"=>"delete issue on web"],
  ["date"=>"2020-07-11","issue"=>"update issue on cms"]
]

你可以使用下面的html格式来制作它

  <input required type="date" value="{{$details->date}}" 
              name="issues[{{$key}}][date]" class="form-control"
                             aria-describedby="emailHelp" >

内部控制器

public function issuesUpdate(Request $request, Project $project)
{
   $issues = $request->issues;
   $insertData = [];
   foreach($issues as $key=>$issue){
      $issue["project_id"] = $project->id;
      $insertData[] = $issue;
   }
   Issue::where('project_id',$project->id)->delete();// to not insert duplicate issues for the same project
   Issue::insert($insertData);
   return redirect()->route('project');
}
