我有类似结构的DB(我没有显示完整的结构):
users (id, name, comments)
company_user (id, company_id, user_id)
companies (id, name)
company_distributor (id, company_id, distributor_id)
distributors (id, name)
我有关系:
公司:
public function users()
{
return $this->belongsToMany('App\User');
}
public function distributors()
{
return $this->belongsToMany('App\Models\Distributor')->withPivot('id')->whereNull('company_distributor.deleted_at');
}
CompanyDistributor:
public function company()
{
return $this->belongsTo('App\Models\Company', 'company_id', 'id');
}
public function distributor()
{
return $this->belongsTo('App\Models\Distributor');
}
当我试图获得评论'来自用户 - 我得到空数据,但请求是正确的:
select users.*,company_user.company_id as pivot_company_id,company_user.user_id as pivot_user_id from users inner join company_user on users.id=company_user.user_id where company_user.company_id in ('1', '2', '3', '4', '7', '9', '10'........)
CompanyDistributorCrudController中的Crud:
$this->crud->addColumn([
// 1-n relationship
'label' => "Comments",
'type' => "select_multiple",
'name' => 'company_id',
'entity' => 'company.users',
'attribute' => "comments",
'model' => "App\Models\Company",
]);
出了什么问题?
当我尝试添加与CompanyDistributor的关系时:
public function users()
{
return $this->company->belongsToMany('App\User');
}
sql查询获取' id'来自' company_distributor'表但不是' company_id'我需要的。
抱歉我的英文
