Laravel Eloquent 无法插入数据库答案

【问题描述】：

我正在使用 Laravel 5.7 制作一个像谷歌表单一样运行的应用程序。这是我已经制作的表格：

我制作了一个雄辩的模型，以便个人详细信息表中的每个名称都有一个包含所有这些表的记录，并在单击提交按钮后将填充的表插入数据库。问题是，它没有成功插入数据库。我不知道是什么问题，这是我的代码：

PersonalDetails.php（雄辩模型）

namespace App;

use Illuminate\Database\Eloquent\Model;

class PersonalDetails extends Model
{
    protected $table = 'personal_details';
    protected $guarded = ['id'];

public function accomodation()
{
    return $this->hasOne('App\Accomodation');
}

public function course()
{
    return $this->hasOne('App\Course');
}

public function proposedStudy()
{
    return $this->hasOne('App\ProposedStudy');
}

public function emergencyContact()
{
    return $this->hasOne('App\EmergencyContact');
}

public function englishTestResult()
{
    return $this->hasOne('App\EnglishTestResult');
}

public function homeInstitution()
{
    return $this->hasOne('App\HomeInstitution');
}

public function insurance()
{
    return $this->hasOne('App\Insurance');
}
}

FormController.php

public function submit(Request $request) {

    $request->validate([
        // Personal Details

【问题讨论】：

任何错误信息？
不，先生，它没有错误消息。我不知道是什么问题
您能否检查浏览器控制台 -> 网络选项卡中的响应代码（200 或 404 或 422）。我猜一些验证失败
我认为你有批量分配问题。您可以在模型中添加可填充变量。你可以在这里查看laravel.com/docs/5.7/eloquent#mass-assignment，你应该把所有的验证放在一个单独的请求文件中。我知道这与您的问题无关，但它会使您的控制器变薄。 laravel.com/docs/5.7/requests希望对你有帮助:)
我猜可能是验证失败。只需检查您所有的Form Fields 和fields under validation。字段可能不匹配。

标签： php laravel eloquent

【解决方案1】：

经过所有这些努力找出问题后，我才意识到我在验证规则中输入了错误的名称。验证规则左侧的名称与html中的名称不同，因此我对html中的名称和验证规则进行了修改。

重要的是我在提交后没有输入任何验证错误消息，因此它不会插入到数据库中。在我输入一些错误消息后，所有字段都返回错误，显示“需要 :attribute”。只是因为验证中的名称与html名称不同：D

谢谢大家帮我解决问题，我解决了:))

【解决方案2】：

尝试使用模型路径，如果模型文件夹在 App 中，则 App\model；

eg:-
App\Insurance::create([
        'insurance_name' => $request->input('insurance'),
        'validity' => $request->input('valid_date'),
        'cover' => $request->input('cover'),
    ]);

【解决方案3】：

在模型中添加$fillalbe：

protected $fillable=['full_name','nationality','...']

您需要在模型上指定fillalbe 属性。阅读更多https://laravel.com/docs/5.7/eloquent#mass-assignment

【讨论】：

如果指定了$guarded 属性，则不需要这样做。 While $fillable serves as a "white list" of attributes that should be mass assignable, you may also choose to use $guarded. The $guarded property should contain an array of attributes that you do not want to be mass assignable. All other attributes not in the array will be mass assignable.
同意 Jeremy，我认为如果我已经附加了除 $guarded 之外的受保护数组，它将是 $fillable 列表
尝试插入静态值。
然后尝试添加$fillable并删除$guarded
转储request时得到的结果

【解决方案4】：

您能否检查您的表迁移或模型关系，然后修改您的表单控制器。

我正在根据您的代码创建示例并成功插入数据库。

个人资料迁移

Schema::create('personal_details', function (Blueprint $table) {
        $table->increments('id');
        $table->string('fullname')->nullable();
        $table->string('nationality')->nullable();
        $table->timestamps();
    });

家庭机构迁移

Schema::create('home_institution', function (Blueprint $table) {
        $table->integer('personal_details_id')->unsigned()->primary();
        $table->string('name')->nullable();
        $table->string('address')->nullable();
        $table->timestamps();

        #Foreign to Table Personal Details.
        $table->foreign('personal_details_id')->references('id')->on('personal_details')->onUpdate('cascade')
            ->onDelete('cascade');

    });

个人细节模型关系

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class PersonalDetails extends Model
{
protected $guarded = ['id'];


public function homeInstitution()
{
    return $this->hasOne('App\HomeInstitution');
}

# Other your Relation

}

表单控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\PersonalDetails;

class FormController extends Controller
{
public function index()
{
    return view('form.index');
}

public function submit(Request $request)
{
    $request->validate([
        // Personal Details
        'fullname' => 'required|string',
        'nationality' => 'required|string',
        // Home Institution
        'name' => 'required|string',
        'address' => 'required|string',
    ]);

    $pd = PersonalDetails::create(
        ['fullname' => $request->get('fullname'), 'nationality' => $request->get('nationality')]
    );

    # Insert into HomeInstitution => base on Model Relation from PersonalDetails
    $pd->homeinstitution()->create(
        ['name' => $request->get('name'), 'address' => $request->get('address')]
    );

    # Insert into other youR relation
    /*$pd->example()->create(
        []
    );*/


    return dd('Successfull Insert');
}
}

也许它可以帮助你。
