Eloquent filter returns wrong Model

I think you are confused by the filter() method; it filters a Collection based on some criteria and returns an array of items from the Collection which satisfy the criteria.

Using dd()gives you the message because you die and dump on a message object.

Thanks @tykus_ikus . So how do set the criteria to only return the last message i.e the nested relation. At the moment it only returns conversation model and its obvious what that is the case.

Do you know how to return the nested relations ?

I would make add a latest_message attribute to the Conversation model, which would be available on a conversation instance.

// Conversation.php

public function getLatestMessageAttribute()
{
    return $this->messages->last(); // 'messages' is the name of the hasMany relationship
}

You can now iterate over your user's conversations collection and display the last message in each conversation:

@foreach(Auth::user()->conversations as $conversation)
    {!! $conversation->latest_message !!}
@endforeach         

Thanks @tykus_ikus I used your suggestion to make some quick fixes.

this is what I did

public function messages() {
        return $this->hasMany(Message::class);
    }

public function getLastestMessage()
    {
        return $this->messages()->get()->last(); // changed this to use relation to retrieve the last in collection
    }

then you can use as follows:

foreach(Auth::user()->conversations as $conversation){
       echo $conversation->getLastestMessage();

    }

You don't need to $this->messages()->get() because you already have a collection from $this->messages

@tykus_ikus Yes you're right I have made the change. Thanks
