Access attribute in Laravel collection - laravel

Question

This is related to another question I asked previously that wasn't answered successfully.
I think I have narrowed it down to make the question more precise.
I have a parent/child BelongsTo relation in Laravel and it is returning the following (which is the result of a {{dd($task->asset->parent_asset())}}
BelongsTo {#657 ▼
#foreignKey: "parent_asset_id"
#otherKey: "id"
#relation: "parent_asset"
#query: Builder {#663 ▶}

}

}
I can see that the "name" attribute is there and I am trying to access that attribute of "name" in the following way but I receive an error "Trying to get property of non-object".
$task->asset->parent_asset->name
How should I be accessing the "name" attribute in the collection?
Model relations:
This is the relation in the asset model:
public function parent_asset()
{
return $this->belongsTo('\pmms\Asset', 'parent_asset_id');
}
and the relation in the task model
public function asset()
{
return $this->belongsTo('\pmms\Asset');
}
results of dd($task) on query $task = Task::with('asset.parent_asset')->first();

Answer 1

I can only assume that your relationships are working.
You are dumping the definition of relationship, not result of the query.
Try using this for query:
$task = Task::with('asset.parentAsset')->first();
And then dump like this:
dd($task->asset->parent_asset->name);
Assuming your relationships are defined correctly this should give you the result you want.
Edit:
As it turns out the relationship must be camelCased in order to use the magic property. More Laravel 4 - Can't retrieve data in a one-to-many relationship
So rename your parent_asset() method to parentAsset() and try the above queries.

Answer 2

I found the answer after much head shaking:
It is not this that I needed to call:
$task->asset->parent_asset->name
It is this:
$task->asset->parent_asset['name']
I am not sure why it is an array in this case but I did dd($task->asset->parent_asset) and it showed an array. Once I changed to an array in my view, it worked like I wanted.
