Where are the rest of the relation in yii2?

Question

Yii

Found two relationships in yii2 hasOne, hasMany.

public function getCompaniesCompany()
    {
        return $this->hasOne(Companies::className(), ['company_id' => 'companies_company_id']);
    }

    public function getDepartamens()
    {
        return $this->hasMay(Departamens::className(), ['branches_branch_id' => 'branch_id']);
    }

I want to know where BelongsTo , Many To Many , etc.

Answer 1

Yii2 doesn't have them. HasOne() is used instead of belongsTo() and hasMany() is used instead of manyToMany() along with viaTable()
