Question

我正在建立一个带有帖子赞的论坛系统，但是由于某种原因，帖子赞的关系不会返回任何数据。

我曾尝试在没有资源的情况下加载数据，并包含在（'all_likes'）中，但这仍然不会返回数据。

我的获取帖子方法：

write()

我的论坛帖子资源：

ConnectedThread

我的论坛帖子模型：

// At this point you have one thread (there may be more,
// but suppose it's only one).
// The thread is executing the code below.

ConnectedThread connectedThread = new ConnectedThread(socket);
connectedThread.start();

// Now you have two threads running simultaneously.
// The new thread is doing whatever the run() method defined in
// ConnectedThread,
// that is that infinite loop with read() calls.
// But this thread goes on.

connectedThread.write();

// The write() call above is executed in this thread,
// which has nothing to do with
// the run() defined in ConnectedThread.

单击“喜欢”按钮后，用户ID和帖子ID将添加到post_likes数据库中。然后，在加载视图时，将显示所有论坛帖子，包括该帖子的点赞关系数据。

我得到的结果是：

public function getPosts($id) 
{
    $response = array();
    $response['posts'] = ForumPostResource::collection(ForumPost::where('thread_id', $id)->get());

    return $response;
}

这应该返回1条类似结果的帖子，因为我的数据库看起来像这样：

id | user_id | post_id

1 | 1501 | 14

我忽略了它正在调用App\PostLike并且外键和本地键顺序错误的事实。

方法定义为：

 public function hasMany($related, $foreignKey = null, $localKey = null)

关系不返回任何数据
