在Laravel中使用Eloquent ORM与多个表一对多的关系

Question

I have three Models User, Email and Phone and database tables Users, Emails and Phones with the columns mentioned below.

  User: id, name
  Emails: id, user_id, emails
  Phones: id, user_id, phones

Right now I am using the following function in User Model to make User relationship with Email and Phone using Eloquent ORM One to Many Relationship

public function profile(){
  $data = array();
  $data['emails'] = $this->hasMany('App\Email');
  $data['phones'] = $this->hasMany('App\Phone');
  return
}

I want to know that it is necessary to use hasMany() method twice or there is any other better way to do this?

Answer 1

You should define the relationships separately:

public function emails()
{
    return $this->hasMany('App\Email');
}

public function phones()
{
    return $this->hasMany('App\Phone');
}

This allows you to query a user like that:

$user = User::with('emails')->with('phones')->find($userId);

You can take a look here for the documentation.

Answer 2

You can do this that way too:

$user = User::find($userId)->load('emails', 'phones');

I think "load's" use is more appropriated in your situation.
