Laravel 表单模型保存错误

Question

每当我更新数据而不是更新数据时，数据都会保存为新条目。 添加任务页面

@extends('master.masterPage')
@section('content')

{!!Form::model($task,['url'=>['employeeTask.update',$task->id], 'class' => 'well form-horizontal']) !!}

    <!-- Text input-->
    <div class="form-group">
    {!! Form::Text('userAssigned', null,array('class' => 'form-control','placeholder'=>'Employee Name')) !!}


    <!-- Text input-->
    <div class="form-group">
   {!! Form::Text('title',null,array('class' => 'form-control','placeholder'=>'Title')) !!}


    <!-- Text input-->
    <div class="form-group">
    {!!Form::Textarea('description',null,array('class' => 'form-control','placeholder'=>'Description')) !!}

    <!-- Text input-->
   {!! Form::Text('client',null,array('class' => 'form-control','placeholder'=>'Client Name')) !!}

   <div class="form-group">
   {!!Form::Text('completionDate',null,array('class' =>'formcontrol','placeholder'=>'Date' )) !!}

    <!-- Button -->
    <div class="form-group">
    {{Form::Submit('Save',['class'=>'glyphicon glyphicon-send'])}}

{!! Form::close() !!}

路由：web.php

Route::resource('employeeTask','employeeTaskController');

员工任务控制器文件名：employeeTaskController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Webpatser\Uuid\Uuid;
use App\Model\task;

class employeeTaskController extends Controller
{
    /**

    public function store(Request $request)
    {
        //
        $task = new task([

        ]);
        $task->save();

    }


    /**

        $task= task::find($id);
        return view('userPage.editTaskPage')->with('task',$task);
    }

    /**

     */
    public function update(Request $request, $id)
    {
        //
        $task = task::find($id);
        $task->userAssigned = $request->employeeName_txt;
        $task->title = $request->title_txt;
        $task->description = $request->description_txt;
        $task->client = $request->clientName_txt;
        $task->completionDate = date('Y-m-d',strtotime($request->completionDate_txt));
        $task->status = $request->status_dd;
        $task->save();
        return redirect('employeeTask')->with('message','task has been Updated Successfully');        
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

请检查当我按下保存时它会转到employee.store 路由而不是employee.update

如果您签入documentation POST 将被路由到store 方法，PUT/PATCH 将被路由到更新方法。

您可以做的是调用updateOrCreate 方法，因此您需要将您的存储方法更改为

public function store(Request $request)
{
    $task = task::updateOrCreate(
        [
            'id' => Uuid::generate()->string // Pass in the ID to cross check
        ],
        [
            'id' => Uuid::generate()->string,
            'userAssigned' => $request->employeeName_txt,
            'title' => $request->title_txt,
            'description' => $request->description_txt,
            'client' => $request->clientName_txt,
            'completionDate' =>date('Y-m-d',strtotime($request->completionDate_txt)),
            'status' => $request->status_dd,
        ]
    );

    return redirect('employeeTask')->with('message','task has been saved Successfully');
}

Answer 2

只需添加这一行：

{!! method_field('put') !!}

在这一行之后：

{!!Form::model($task,['url'=>['employeeTask.update',$task->id], 'class' => 'well form-horizontal']) !!}

所以，laravel 会知道你需要更新数据并使用方法 update() 而不是 store()
