too long

Question

I have two models, Topic Model and a Post Model. A Topic can have multiple posts.

public function posts()
{
    return $this->hasMany('FPost');
}

Now to get the latest post for a topic I am doing something like the following

public function latestPost()
{
    return $this->posts()->where('f_topic_id',"=",$this->id)->take(1);

}

and then I am getting the latest post attributes as such (for a particular topic)

{{$topic->latestPost()->first()['title']}}

Now , I have tried enough , but it seems that this is not working for me

{{$topic->latestPost()->first()->title}}

my question is why can't i get the properties of the post model ?

Update.. The topic model looks like this

class FTopic extends Eloquent {
    protected $fillable =['topictitle','topicdescription'];

    public function forumCategory()
    {
        return $this->belongsTo('FCategory');
    }

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function posts()
    {
        return $this->hasMany('FPost');
    }

    public function latestPost()
    {
        return $this->posts()->where('f_topic_id',"=",$this->id)->take(1);

    }




    public $rules = [
        'topictitle' => 'required|min:10',
        'topicdescription' => 'required|max:10'
    ];

    public  $errors;

    public function isValid()
    {
        $validation = Validator::make($this->attributes, $this->rules);
        if($validation-> passes())
            return true;
        $this->errors = $validation->messages();
        return false;
    }







    protected $table = 'ftopics';



} 

Update 2 This is how I am using it. thanks

Change your latestPost method to:

public function scopeLatestPost($query)
{
    return $this->posts()->orderBy('id', 'desc');
}

Then use something like this:

$ptitle = FTopic::find(1)->latestPost()->first()->title;
