Laravel Eloquent无法插入数据库

Question

我正在制作一个使用Laravel 5.7像Google窗体一样运行的应用程序。这是我已经制作的表格：

我做了一个雄辩的模型，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中。问题是，它没有成功插入数据库。我不知道出了什么问题，这是我的代码：

PersonalDetails.php（雄辩的模型）     

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

Answer 1

尝试使用模型路径，如果模型文件夹位于App内，则App \ model；

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

Answer 2

在模型中添加$fillalbe：

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

您将需要在模型上指定fillalbe属性。在https://laravel.com/docs/5.7/eloquent#mass-assignment

您可以检查表迁移或模型关系，然后修订表单控制器。

我正在根据您的代码创建示例，并将其成功插入数据库中。

个人详细信息迁移

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');

    });

个人详细资料模型关系

<?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');
}
}

也许它可以帮助您。

最后，在经过所有这些努力以找出问题之后，我才意识到自己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，因此我重新定义了html和验证规则中的名称。

重要的是，提交后我没有放置任何验证错误消息，因此不会将其插入数据库。在我输入一些错误消息之后，所有字段都返回了错误消息，指出“：attribute是必需的”。仅仅是因为验证中的名称与html名称不同：D

谢谢你们帮我解决了这个问题，我解决了：））
