[tbarbugli]

is it possible to add the definition of the FeedBox\Article model?

[mrgodhani]

That's the model I have @tbarbugli

<?php

namespace FeedBox;

use GetStream\StreamLaravel\Eloquent\ActivityTrait;
use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    use ActivityTrait;
    protected $table = 'articles';
    protected $fillable = [
        'unique_id',
        'title',
        'url',
        'domain',
        'author',
        'summary',
        'content',
        'lead_image_url',
        'date_published',
        'feed_id'
    ];

    /**
     * Belongs to Feed
     * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
     */
    public function feed() {
        return $this->belongsTo('FeedBox\Feed');
    }
}

ActivityTrait assumes that your model has a 'user' attribute (for activity.actor). Can you look at the instructions here: https://github.com/GetStream/stream-laravel#activity-fields?

Cool thanks works.
