Php Laravel 5:在用户配置文件中显示此评论所属的帖子标题
我试图在他的个人资料页面上显示用户评论所属的帖子标题 这就是我在用户个人资料上所做的Php Laravel 5:在用户配置文件中显示此评论所属的帖子标题,php,mysql,laravel,laravel-5,Php,Mysql,Laravel,Laravel 5,我试图在他的个人资料页面上显示用户评论所属的帖子标题 这就是我在用户个人资料上所做的 public function show($user, Post $post) { $user = User::whereName($user)->with('posts.votes')->with('comments')->firstOrFail(); $comments = $user->comments; $linkKarma = User::find($u
public function show($user, Post $post)
{
$user = User::whereName($user)->with('posts.votes')->with('comments')->firstOrFail();
$comments = $user->comments;
$linkKarma = User::find($user->id)->votes()->sum('value');
$commentKarma = User::find($user->id)->commentvotes()->sum('value');
$total_comments = $user->comments->count();
$isModerator = false;
return view('user/profile')->with('user', $user)
->with('linkKarma', $linkKarma)
->with('commentKarma', $commentKarma)
->with('comments', $comments)
->with('total_comments', $total_comments)
->with('isModerator', $isModerator);
}
我基本上得到了他所有的东西,从帖子
,投票
和评论
——但是,我无法在用户配置文件页面上显示这些评论所属的帖子
我可以在foreach()
中使用$comment->post\u id
,但这只能获取post id,但我不能使用$comment->post->title
尝试获取无对象的属性时会出错
我该怎么做
我的数据库
posts: id, title, user_id, subreddit_id...
comments: id, comment, user_id, post_id...
user: id, name, email...

试试这个:
$comment->posts->title
(注意它是“posts”而不是“post”)
您的注释模型具有函数posts
,因此当您从注释访问它时,您可以使用该函数名访问它,如上所示
我会将帖子重命名为post,因为评论属于一个帖子,而不是多个帖子
也改变
$user = User::whereName($user)->with('posts.votes')->with('comments')->firstOrFail();
将来
这使得尝试获取非对象的属性
您可以验证注释模型中的函数名是否为posts
,以及在视图文件中的foreach循环中,您是否通过$Comment->posts->title
访问它?另外,当您添加或打印$comment时会输出什么?我无法访问$comment->posts->title
,这就是问题所在。评论没有与帖子链接,因为我已经迫不及待地加载帖子。投票将获得用户所有评论的集合。尝试更改$user=user::whereName($user)->with('posts.voates')->with('Comments')->firstOrFail()
将成为$user=user::whereName($user)->with('posts.vows')->with('comments.posts')->firstOrFail()代码>请提供用于访问用户评论文章标题的代码。还要验证您是否确实有一篇帖子,其id与评论记录中的帖子id相匹配。确保您的函数名匹配,因为您的问题显示的是post,但通过post访问。
