How to select data from several linked tables in YII1 with one query through links?

Question

Yii

Hello, I have 7 tables, here is the
screen
I made such connections
Contacts

public function relations()
    {
        return array(
            'company' => array(self::BELONGS_TO, 'Company', 'company_id'),
        );
    }

company

public function relations()
    {
        return array(
            'category' => array(self::BELONGS_TO, 'BusinessCategory', 'category_id'),
            'contacts' => array(self::HAS_MANY, 'Contacts', 'company_id'),
            'staffCompanies' => array(self::HAS_MANY, 'StaffCompany', 'company_id'),
        );
    }

business category

public function relations()
    {
        return array(
            'companies' => array(self::HAS_MANY, 'Company', 'category_id'),
        );
    }

StaffCompany

public function relations()
    {
        return array(
            'emailStaffCompanies' => array(self::HAS_MANY, 'EmailStaffCompany', 'staff_company_id'),
            'networkStaffCompanies' => array(self::HAS_MANY, 'NetworkStaffCompany', 'staff_company_id'),
            'phoneStaffCompanies' => array(self::HAS_MANY, 'PhoneStaffCompany', 'staff_company_id'),
            'company' => array(self::BELONGS_TO, 'Company', 'company_id'),
        );
    }

PhoneStaffCompany, NetworkStaffCompany, EmailStaffCompany

public function relations()
    {
        return array(
            'staffCompany' => array(self::BELONGS_TO, 'StaffCompany', 'staff_company_id'),
        );
    }

I tried to make such a request to Contacts

Contacts::model()->with('company')->findAll(array("condition"=>"user_id = $user_id"));

but it gives out only Contact and Company
A, its Staff (their phones are soap) and the category
How is it better to make a request so that I contact the contact once, and he collects all the information in other tables by connections?
