Subscribed topics - php

Question

In my forum I'm showing all topics. It looks like this:
So a user can subscribe by clicking on the red hearth.
I'm loading the topics with this json:
{
"forum": {
"id": 1,
"slug": "test",
"name": "test",
"description": "test",
"created_at": null,
"updated_at": null
},
"topics": {
"total": 6,
"per_page": 5,
"current_page": 1,
"last_page": 2,
"next_page_url": "http://forum.dev/api/forum/test?page=2",
"prev_page_url": null,
"from": 1,
"to": 5,
"data": [
{
"id": 1,
"slug": "1",
"name": "1",
"description": "1",
"forum_id": 1,
"created_at": null,
"updated_at": null
},
{
"id": 2,
"slug": "2",
"name": "1",
"description": "1\t",
"forum_id": 1,
"created_at": null,
"updated_at": null
},
{
"id": 3,
"slug": "1",
"name": "1",
"description": "1\t",
"forum_id": 1,
"created_at": null,
"updated_at": null
},
{
"id": 4,
"slug": "1",
"name": "1",
"description": "1",
"forum_id": 1,
"created_at": null,
"updated_at": null
},
{
"id": 5,
"slug": "1",
"name": "1",
"description": "1",
"forum_id": 1,
"created_at": null,
"updated_at": null
}
]
}
}
I'm returning that ^ like this:
$forum->topics()->orderBy('created_at', 'DESC')->paginate(5);
So how do I get a subscribe value on every topic object?
So like this:
"data": [
{
"id": 1,
"slug": "1",
"name": "1",
"description": "1",
"forum_id": 1,
"created_at": null,
"updated_at": null,
"subscribed": true
},
I already made this on my topic model:
/**
* #return mixed
*/
public function subscriptions()
{
return Topic::subscribedBy(Auth::user())->get();
}
And it's working. But how do I send that ^ with every topic.

Answer 1

You can add an attribute (which is not present in the database) by creating an accessor.
public function getSubscriptionsAttribute()
{
return Topic::subscribedBy(Auth::user())->get();
}
and then adding it to the $append property.
protected $appends = ['subscriptions'];
If you're using the $visible whitelist you might have to add it to that property too.
