無法從 laravel 在我的數據庫中插入數據

Question

當我嘗試將數據插入到我的數據庫中時，Laravel 沒有插入記錄，但這很奇怪，因為當我遷移表以能夠執行數據庫時，Laravel 可以毫無問題地創建它們，我不知道我會是什么如果遷移運行但沒有存儲則做錯

路線：

Route::post('/proyecto', [ctrlCars::class,'store'])->name('cars'); 

控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\cars;

class ctrlCars extends Controller

{
    public function store(Request $request){

    $request->validate([
        'carRegistration'=> ['required','min:6'],
        'name'=> ['required','min:6'],
        'fromProduction' => ['required','min:6'],
        'stateStored'=> ['required'],
        'model'=> ['required','min:4'],
        'dateAssembled' => ['required'],
    ]);

    $car = new cars;
    $car->carRegistration = $request->carRegistration;
    $car->name = $request->name;
    $car->fromProduction = $request->fromProduction;
    $car->stateStored = $request->stateStored;
    $car->model = $request->model;
    $car->dateAssembled = $request->dateAssembled;
    $car-> save();

    return redirect()->route('cars')->with('success','Registro guardado satisfactoriamente');
}}

模板：

 @extends('header') @section('content') <div class="container w-10 mt-5 border p-4"> <form action="{{ route('cars') }}" method="POST"> @csrf @if (session('success')) <h6 class="alert alert-success">{{ session('success') }}</h6> @endif @error('carRegistration') <h6 class="alert alert-danger">{{ $message }}</h6> @enderror <p class="h2">Registro vehiculos</p> <br> <div class="row"> <section class="col-md-12"> <div class="form-group"> <section class="row"> <div class="col-md-4"> <label for="carRegistration" class="form-label">Placa</label> <input type="text" class="form-control" name="carRegistration" placeholder="CDE001" maxlength="6"> </div> <div class="col-md-4"> <label for="name" class="form-label">Nombre</label> <input type="text" class="form-control" name="name" placeholder="Ferrari Enzo"> </div> <div class="col-md-4"> <label for="fromProduction" class="form-label">Planta Produccion</label> <input type="text" class="form-control" name="fromProduction" placeholder="Bmw sede1"> </div> </section> <section class="row mt-4"> <div class="col-md-4"> <label for="placa" class="form-label">Fecha Ensamble</label> <input type="date" class="form-control" name="dateAssembled" placeholder="CDE001"> </div> <div class="col-md-4"> <label for="model" class="form-label">Módelo Matricula</label> <input type="text" class="form-control" name="model" maxlength="4" placeholder="2013"> </div> <div class="col-md-4"> <label for="stateStored" class="form-label">Ciudad Almacenamiento</label> <Select type="text" class="form-control" id="stateStored" placeholder="Medellin"> <option value=''>Elija una opción</option> <option value='Medellin'>Medellín</option> <option value="Bucaramanga">Bucaramanga</option> <option value="Cali">Cali</option> <option value="Bogota">Bogotá</option> </Select> </div> </section> </div> </section> </div> <button type="submit" class="btn btn-success mt-4">Guardar</button> </form> </div>

Answer 1

感謝您的幫助，錯誤來自因為我從 controller 上的名稱調用並且在此輸入中只有 ID，並且在此字段的驗證中具有“必需”； 我不知道如何回復評論，但感謝 aynber 和 Daniel L，你們幫了大忙

問題出在您的模板上。 select 標簽應該有一個名稱屬性。 將您的模板更改為此

   $car->dateAssembled = $request->dateAssembled;
    $car-> save();

    return redirect()->route('cars')->with('success','Registro guardado satisfactoriamente');
}}
Template:

@extends('header')

@section('content')

<div class="container w-10 mt-5 border p-4">

    <form action="{{ route('cars') }}" method="POST">
        @csrf

        @if (session('success'))
            <h6 class="alert alert-success">{{ session('success') }}</h6>
        @endif

        @error('carRegistration')
            <h6 class="alert alert-danger">{{  $message }}</h6>
        @enderror

        <p class="h2">Registro vehiculos</p>
        <br>
        <div class="row">

第一次評論您的驗證部分，然后重試。 如果你的數據成功插入。 然后您需要修改您的必填字段，如下所示。

替換 ['required','min:6']

像這樣：'required|min:6',
