Laravel using where clause on a withCount method

I am trying to do a where clause on withCount method of laravel’s eloquent query builder using this piece of code.

$posts = Post::withCount('upvotes')->where('upvotes_count', '>', 5)->get();

and this code is giving me this error.

SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘upvotes_count’ in ‘where clause’ (SQL: select , (select count() from upvotes where upvotes.upvoteable_id = posts.id and upvotes.upvoteable_type = AppPost) as upvotes_count from posts where upvotes_count > 5)

So from what I can guess is that upvotes_count isn’t selected and hence the column is not being found, BUT if I execute this piece of code.

$posts = Post::withCount('upvotes')->get();

Then I am getting this output.

{
"id": 1,
"user_id": 15,
"title": "Voluptatum voluptas sint delectus unde amet quis.",
"created_at": "2016-10-07 13:47:48",
"updated_at": "2016-10-07 13:47:48",
"upvotes_count": 7
},
{
"id": 2,
"user_id": 2,
"title": "Molestiae in labore qui atque.",
"created_at": "2016-10-07 13:47:48",
"updated_at": "2016-10-07 13:47:48",
"upvotes_count": 2
},

Which basically means that upvotes_count is being selected, hence i am really confused about how to solve this problem.

(More options that I tried so far are given below with the respective error associated to it.)

$posts = Post::where('id', $id)->withCount(['upvotes' => function($query) {
        $query->where('upvotes_count', '>', 5);
    }])->get();

error.

SQLSTATE[42S22]: Column not found: 1247 Reference ‘upvotes_count’ not supported (forward reference in item list) (SQL: select , (select count() from upvotes where upvotes.upvoteable_id = posts.id and upvotes.upvoteable_type = AppPost and upvotes_count > 5) as upvotes_count from posts where id = 1)

code.

$posts = Post::where('id', $id)->with(['upvotes' => function($query) {
        $query->select('upvoteable_id AS upvotes_count');
    }])->where('upvotes_count', '>', 5)->get();

AND

$posts = AppPost::where('id', $id)->with(['upvotes' => function($query) {
        $query->selectRaw('upvoteable_id AS upvotes_count');
    }])->where('upvotes_count', '>', 5)->get();

error.

SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘upvotes_count’ in ‘where clause’ (SQL: select * from posts where id = 1 and upvotes_count > 5)

I just want to use where clause on a count() method which is in a relationship with a parent model.

Answer

You can achieve requested result by using:

$posts = Post::withCount('upvotes')
         ->having('upvotes_count', '>', 5)
         ->get();
