How should I be able to output the count of a relation? I set the models hasMany and I get the object like this: [{"size_id":"3","count":"2"}] unfortunately I'm not able to access it with a .count in twig... any suggestions? Thanks a lot

It will work just like you're trying to use it. Though I'm assuming you have it setup right:

Let's say you have a model called "Album" which hasMany "Songs" such that the relationship would be accessed in PHP like so:

$album = Album::find($id);
$songs = $album->songs();

If this works then in Twig you should be able to do:

<div>This album has {{ album.songs.count }} songs!!!</div>

thnx for the input, but unfortunately it didn't help. I have everything setup right, but somehow the model relationship is displayed in json (square brackets and {} ), therefore twig is not able to access it with the "dot". I have a "Sports" model relationship with "Products" setup: 'products_count' => ['Newcode\Product\Models\Product', 'count' => true]

in controller: $this['sports'] = Sports::all(); and in twig: {% for sport in sports %} {{ sport.products_count }} {% endfor %}

The result is [{"size_id":"3","count":"2"}]

but I am not able to access the count variable because of square brackets. What am I doing wrong? :-/

{% for sport in sports %} {{ sport.products_count.count }} {% endfor %}

Thanx, I did exactly that, but I get wrong result. No matter what count field shows, I get 1 :-/

Hmm, I'm not sure. Your original data shows it should be 2. If you believe this to be a bug with October, create a sterile test case (test plugin and theme) and submit it to GitHub for testing.

got it, thnx. Btw loving October. Good work!

and how to use in a php class ? doing this is rising an exception

$relations_count->count````

You just be able to do count($record->relation)

I think you should move the 'products_count' => ['Newcode\Product\Models\Product', 'count' => true] relation definition to hasOne instead of hasMany in Sports model class. Something like this:

$hasOne = [
   'products_count' => ['Newcode\Product\Models\Product', 'count' => true]
];

The hasMany relation provides a collection and that's why sports.products_count.count doesn't work in twig. If you define the count relation in $hasOne you should get a model object with a "count" attribute and in this case sports.products_count.count should work in twig.

In addition, $this->products_count->count should also work in Sports model class.

i know this was 11 months ago but to show the correct count do this

$model->relation_count[0]->count

for twig

model.relation_count[0].count

Does it have to do with: protected $jsonable = ['...']; ?

This was the only thing that worked for me. Thank you.
