Question

早些时候我正在研究核心php，目前我转向laravel和 MVC。所以我也不太了解mvc和laravel。我正面对一个问题。帮我解决这个问题。

我有两张桌子：

公司
company_address

公司模型：

class Company extends Eloquent {

    protected $fillable = [
                            'name',
                            'email',
                            'website',
                            'logo',
                            'phone',

                        ];
    protected $primaryKey = 'id';
    protected $table = 'companies';
}

company_address的模型：

class Companyaddress extends Eloquent {

    protected $fillable = [
                            'companies_id',
                            'address_line_1',
                            'address_line_2',
                            'city',
                            'state',
                            'zipcode',
                            'country_id',                           
                        ];
    protected $primaryKey = 'id';
    protected $table = 'company_address';
}

我的控制器保存这两个表：

public function store(CompanyRequest $request, Company $company, Companyaddress $companyaddress){   

        if(!Entrust::can('create-company'))
            return response()->json(['message' => trans('messages.permission_denied'), 'status' => 'error']);

        $data = $request->all();
        $company->fill($data)->save();
        $companyaddress->fill($data)->save();
        storeCustomField($this->form,$company->id, $data);

        $this->logActivity(['module' => 'company_address','module_id' => $company->id,'activity' => 'added']);

        return response()->json(['message' => trans('messages.company').' '.trans('messages.added'), 'status' => 'success']);
    }

我的代码运行正常。在提交我可以根据我的模型存储数据。我想将company表中的主键存储在company_address表中作为外键。所以将来我可以显示特定公司的地址。怎么做？

Answer 1

这样做的好方法是使用雄辩的关系定义两者之间的关系。参见：

https://laravel.com/docs/5.4/eloquent-relationships

首先，在Company模型上定义关系：

public function address()
{
    return $this->hasOne(Companyaddress:class);
}

然后在您的控制器中，您可以执行以下操作：

$company = Company::create($data);
$company_address = Companyaddress::create($data);


$company->address()->save($company_address);

Answer 2

将它放在$ data变量定义之前。（因为您已经设置了$ company集合）

$request->merge(['companies_id'=>$company->id]);

在$ companyaddress之前

。此外，不需要$ data变量（恕我直言）

Answer 3

在保存公司地址之前设置公司ID：

$data->companies_id = $company->id;

或

$data['companies_id '] = $company->id;

商店方法：

public function store(CompanyRequest $request, Company $company, Companyaddress $companyaddress){   

        if(!Entrust::can('create-company'))
            return response()->json(['message' => trans('messages.permission_denied'), 'status' => 'error']);

        $data = $request->all();
        $company->fill($data)->save();
        $data->companies_id = $company->id; //Set company id here
        $companyaddress->fill($data)->save();
        storeCustomField($this->form,$company->id, $data);

        $this->logActivity(['module' => 'company_address','module_id' => $company->id,'activity' => 'added']);

        return response()->json(['message' => trans('messages.company').' '.trans('messages.added'), 'status' => 'success']);
    }

Answer 4

首先通过添加函数在模型中添加一些关系。

在您的公司模式中。

class Company extends Eloquent {

    protected $fillable = [
                            'name',
                            'email',
                            'website',
                            'logo',
                            'phone',

                        ];
    protected $primaryKey = 'id';
    protected $table = 'companies';

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

在您的CompanyAddress模型中

。

class Companyaddress extends Eloquent {

    protected $fillable = [
                            'companies_id',
                            'address_line_1',
                            'address_line_2',
                            'city',
                            'state',
                            'zipcode',
                            'country_id',                           
                        ];
    protected $primaryKey = 'id';
    protected $table = 'company_address';

    public function companyAddress() 
    {
      return $this->belongsTo('App\Company');
    }
}

然后在您的控制器中。

y＆＃39;可以在您的方法中添加此代码。将save（）方法转换为＆＃34;公司＆＃34; table，获取最后插入的ID，假设您的主键是自动增量。

$companyAddress = new CompanyAddress;
$companyAddress->companies_id = $data->id;

$companyAddress->save();

您可以将此文档作为参考： https://laravel.com/api/5.4/Illuminate/Database/Eloquent/Relations.html

Answer 5

在您的情况下，如果一家公司有一个地址，您应该将其合并到一个表中。但如果你需要，请点击这里：

Model Company.php

class Company extends Eloquent {
protected $fillable = [
                        'id',
                        'name',
                        'email',
                        'website',
                        'logo',
                        'phone',

                    ];
protected $primaryKey = 'id';
protected $table = 'companies';

public function address(){
  $this->hasOne(CompanyAddress::class,'company_id','id')
}
}

Model CompanyAddress.php

class CompanyAddress extends Eloquent {

protected $fillable = [
                        'company_id',
                        'address_line_1',
                        'address_line_2',
                        'city',
                        'state',
                        'zipcode',
                        'country_id',                           
                    ];
protected $table = 'company_address';
}

在您的控制器中

public function store(CompanyRequest $request, Company $company, Companyaddress $companyaddress){   

    if(!Entrust::can('create-company'))
        return response()->json(['message' => trans('messages.permission_denied'), 'status' => 'error']);

    $data = $request->all();
    $company->fill($data)->save();
    $data->company_id = $company->id;
    $companyaddress->fill($data)->save();


    $this->logActivity(['module' => 'company_address','module_id' => $company->id,'activity' => 'added']);

    return response()->json(['message' => trans('messages.company').' '.trans('messages.added'), 'status' => 'success']);
}

public function getCompany($id){
    $company = Company::find($id);
    $company->address;
    return $company->toArray();
}

以及调用getCompany（$ id）

时的结果

{
    id : ...,
    name : ...,
    .
    .
    .
    address : {
               company_id: ...,
               address_line_1: ...,
               .
               .
               .
              }
}

希望它会有所帮助。感谢。
