Laravel 使用 where 和多个 whereHas

Question

我想使用以下代码将过滤器应用于用户的帖子：

        $user = $request->userid;
        $query = Post::query()
            ->where('post.owner.username', $username)
            ->when($request->filled('userid'), function (Builder $query) use ($user) {
                    $query->whereHas('tags', function (Builder $q) use ($user) {
                        $q->where('taggeduser.id', $user);
                    })->orWhereHas('comments', function (Builder $q) use ($user) {
                        $q->where('comment.owner.id', $user);
                    });
            })
            ->when($request->filled('searchText'),
                function (Builder $query) use ($username, $searchText) {
                    $query->whereRaw(['post.owner.username' => ['$eq' => $username]]);
                    $query->getQuery()->projections = ['score' => ['$meta' => 'textScore']];
                    $query->whereRaw(['$text' => ['$search' => $searchText]])->orderByDesc('post.taken_at_timestamp');
                })
            ->when($request->filled('location'),
                function (Builder $query) use ($location) {
                    $query->where('post.location.id', $location);
                });

一切都很好，除了请求有用户 ID，它通过->when($request->filled('userid')并且结果为空，我想获取已在用户帖子中标记或评论的用户，将用户 ID 设置为' tags' 和 'comments' 的关系，我得到$q->where('taggeduser.id', $user);

但是$query->get()是空的。

尝试这个

$user = $request->userid;
        $query = Post::where('post.owner.username', $username)
            ->when($request->filled('userid'), function (Builder $query) use ($user) {
                    $query->whereHas('tags', function (Builder $q) use ($user) {
                        $q->where('taggeduser.id', $user);
                    })->orWhereHas('comments', function (Builder $q) use ($user) {
                        $q->where('comment.owner.id', $user);
                    });
            })
            ->when($request->filled('searchText'),
                function (Builder $query) use ($username, $searchText) {
                    $query->whereRaw(['post.owner.username' => ['$eq' => $username]]);
                    $query->getQuery()->projections = ['score' => ['$meta' => 'textScore']];
                    $query->whereRaw(['$text' => ['$search' => $searchText]])->orderByDesc('post.taken_at_timestamp');
                })
            ->when($request->filled('location'),
                function (Builder $query) use ($location) {
                    $query->where('post.location.id', $location);
                })->get();
