mysql - How to update a pivot table using Eloquent in laravel 5

Question

I am new to laravel. I am working on a laravel 5 app and I am stuck here. I have 2 models as such:

class Message extends Eloquent{

    public function user()
    {
        return $this->belongsTo('AppUser', 'from');
    }

    public function users()
    {
        return $this->belongsToMany('AppUser')->withPivot('status');
    }
}

class User extends Eloquent {

    public function messages()
    {
        return $this->hasMany('AppMessage', 'from');
    }

    public function receive_messages() {
        return $this->belongsToMany('AppMessage')->withPivot('status');
    }
}

There exist a many-to-many relationship between Message and User giving me a pivot table as such:

Table Name: message_user
Colums:
message_id
user_id
status

I have an SQL query as such:

update message_user
set status = 1
where user_id = 4 and message_id in (select id from messages where message_id = 123)

How can I translate this query to the laravel equivalent?

Answer 1

The code below solved my problem:

$messages  = Message::where('message_id', $id)->get();
foreach($messages as $message)
   $message->users()->updateExistingPivot($user, array('status' => 1), false);
