Accessing Pivot table "3rd Model relationship" in Laravel Eloquent - php

Question

I have this Many-to-Many relation Laravel Eloquent relationship
The Models are:
class Email extends Model //actually represent the email account
{
protected $table = 'emails';
protected $fillable = [
'user_id',
'name',
];
public function messages() {
return $this->belongsToMany(Message::class)->withPivot('email_subtype_id');
}
}
class Message extends Model //actually represent the email message
{
protected $table = 'messages';
protected $fillable = [
'subject',
'body ',
];
public function emails() {
return $this->belongsToMany(Email::class)->withPivot('email_subtype_id');
}
}
class EmailMessage extends Pivot //actually represent the pivot table
{
protected $table = 'email_message';
protected $fillable = [
'email_id',
'message_id',
'email_subtype_id',
];
public function email() {
return $this->belongsTo(Email::class);
}
public function message() {
return $this->belongsTo(Message::class);
}
//this is the relation to a third model called EmailSubtype
//I want to include this relation to the Pivot when using it
public function subtype() {
return $this->belongsTo(EmailSubtype::class, 'email_subtype_id');
}
}
class EmailSubtype extends Model //3rd Model need to be included with Pivot
{
protected $table = 'email_subtypes';
protected $fillable = [
'name'
];
public function pivotEmailSubtype(){
return $this->hasMany(Pivot::class, 'email_subtype_id');
}
}
I am able to do this in the Controller:
$email = Email::find(1);
foreach($email->messages as $message) {
$subtype_id = $message->pivot->email_subtype_id;
dd($subtype_id); //1 that relates to subtype: CC Email Account
//also I can get the name indirectly away from the relation as follows:
$subtypeName = EmailSubtype::find($subtype_id)->first()->name;
dd($subtypeName);
}
Here I am getting the email_subtype_id only by direct pivot relation but have to do extra work to get the related email sub-type name.
I need to get the email sub-type name [Directly] from the 3rd Model EmailSubtype relationship oneToMany [hasMany and belongsTo] that relates to Pivot model with EmailSubtype model using something like:
$message->pivot->subtypeName;
Any help please!

Answer 1

Use this:
public function messages() {
return $this->belongsToMany(Message::class)->withPivot('email_subtype_id')
->using(EmailMessage::class);
}
$message->pivot->subtype->name
