Php 拉威尔通过中间表格取得了进展

考虑以下数据库方案：

companies
    -- id
    -- name

logos
    -- id
    -- active
    -- company_id
    -- image_id

images
    -- id
    -- filename
    -- path
    -- type

然后，我将模型中的关系定义为：

Company.php

public function logos() {
    return $this->hasMany('App\Models\Logo');
}

public function image() {
    $this->belongsTo('App\Models\Image');
}

public function show($id) {
    $company = Company::findOrFail($id);
    $requester = JWTAuth::parseToken()->toUser();
    if( !$requester->hasRole('noc') && $requester->company_id != $company->id) {
        return $this->response->errorUnauthorized("You have no rights to view this company profile.");
    }

    // I am trying to fetch it this way //
    $company->logos;
    foreach ($company->logos as $logo) {
        return $logo->image;
    }
    return $this->response->array(compact('company'))->setStatusCode(200);
}

Logo.php

public function logos() {
    return $this->hasMany('App\Models\Logo');
}

public function image() {
    $this->belongsTo('App\Models\Image');
}

public function show($id) {
    $company = Company::findOrFail($id);
    $requester = JWTAuth::parseToken()->toUser();
    if( !$requester->hasRole('noc') && $requester->company_id != $company->id) {
        return $this->response->errorUnauthorized("You have no rights to view this company profile.");
    }

    // I am trying to fetch it this way //
    $company->logos;
    foreach ($company->logos as $logo) {
        return $logo->image;
    }
    return $this->response->array(compact('company'))->setStatusCode(200);
}

现在我想根据它的标识和图像来确定具体的公司。因此，我尝试以这种方式获取它，但它抛出了错误：

Relationship方法必须返回Illumb\Database\Eloquent\Relations\Relationship类型的对象

CompanyController.php

public function logos() {
    return $this->hasMany('App\Models\Logo');
}

public function image() {
    $this->belongsTo('App\Models\Image');
}

public function show($id) {
    $company = Company::findOrFail($id);
    $requester = JWTAuth::parseToken()->toUser();
    if( !$requester->hasRole('noc') && $requester->company_id != $company->id) {
        return $this->response->errorUnauthorized("You have no rights to view this company profile.");
    }

    // I am trying to fetch it this way //
    $company->logos;
    foreach ($company->logos as $logo) {
        return $logo->image;
    }
    return $this->response->array(compact('company'))->setStatusCode(200);
}

有人能帮我吗？：）谢谢

使用：

---

不起作用，抛出：

调用null上的成员函数addagerConstraints（）

，这是因为您忘记将

return

添加到

图像

关系中。：D是的，我没有！谢谢：），我会在6分钟内接受你的回答：）酷。很高兴这有帮助。）
