我正在尝试通过Laravel构建的Web服务中的表单插入数据（日期类型数据）。
solicitacoes.blade.php代码：
@extends('layout.app', ["current" => "solicitacaos"])
@section('body')
<div class="container">
<div class="card-border">
<div class="card-body">
<h3 class="card-title">Solicitações</h3>
<table class="table table-striped table-bordered table-hover">
<tr>
<th> Professor
</th>
<th>
Criação
</th>
<th>
Data Solicitação
</th>
<th>
Nome do Produto
</th>
<th>
Observações
</th>
<th>
Status
</th>
<th>
Ação
</th>
</tr>
@foreach($sols as $sol)
@php
dd($sol)
@endphp
<tr>
<td> {{$sol->nome_professor}}
</td>
<td> {{$sol->criacao}}
</td>
<td> {{dd($sol)}}
</td>
<td> {{$sol->nome_produto}}
</td>
<td> {{$sol->observacao}}
</td>
<td> {{$sol->status}}
</td>
<td>
<a href="/solicitacao/apagar/{{$sol->id}}" class="btn btn-sn btn-danger">Cancelar</a>
</td>
</tr>
@endforeach
</table>
</div>
</div>
</div>
@endsection
错误出现在第"{{ \Carbon\Carbon::parse($sol->solicitacao_data->from_date)->format('d/m/Y')}} "行。
即使我将这一行改为"{{$sol->solicitacao_data}} "，我仍然会遇到相同的错误。
控制器代码如下：
$date_sol = new DateTime();
$date_sol = DateTime::createFromFormat("d/m/Y",$request->input('solicitacao_data'));
$sol->solicitacao_data = $date_sol;
$sol->save();
我想插入 '25/2/2020'，但是我得到了以下错误：
Facade\Ignition\Exceptions\ViewException 未定义属性：stdClass::$solicitacao_data (View: C:\xampp\htdocs\laravel\workflow-novo\resources\views\solicitacoes.blade.php)
数据库表通过迁移创建，如下所示：
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateSolicitacaosTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('solicitacaos', function (Blueprint $table) {
$table->bigIncrements('id');
$table->bigInteger('id_users')->unsigned();
$table->foreign('id_users')->references('id')->on('users');
$table->bigInteger('id_produto')->unsigned();
$table->foreign('id_produto')->references('id')->on('produtos');
$table->string('status');
$table->string('observacao');
$table->date('solicitacao_data');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('solicitacaos');
}
}
我需要使用 Laravel 存储和恢复日期。如何在不出现上述错误的情况下实现？
我注意到，如果尝试保存时间，则数据库保存无法正常工作。例如，以下代码：
$date_sol = Carbon::createFromFormat("d/m/Y H:i:s","20/12/2020 01:00:00");
$sol->solicitacao_data = $date_sol;
将以下数据存储在solicitacao_data列中。
MariaDB [login]> select * from solicitacaos;
+----+----------+------------+------------+------------+------------------+-----
----------------+---------------------+
| id | id_users | id_produto | status | observacao | solicitacao_data | crea
ted_at | updated_at |
+----+----------+------------+------------+------------+------------------+-----

-12-31 01:27:33 | 2019-12-31 01:27:33 |
+----+----------+------------+------------+------------+------------------+-----
----------------+---------------------+
4 rows in set (0.001 sec)
请注意，只有日期被存储。
我在solicitacao.blade.php中执行了dd($sol)命令，并获得了以下结果：
{#341 ▼
+"id": 1
+"status": "Em Análise"
+"nome_professor": "Olavo"
+"criacao": "2019-12-31 02:08:11"
+"nome_produto": "Cadeira"
+"observacao": "awdcasd"
}
尽管该表格具有我之前展示的列。
MariaDB [login]> select * from solicitacaos;
+----+----------+------------+------------+------------+------------------+-----
