Php Laravel$posts->；注释（）不是'；我不在这里工作

以下是我的模型中的代码：

models/Book.php

类目扩展\有说服力{

function posts() {
    return $this->hasMany('Post');
}

function user() {
    return $this->belongsTo('User');
}

public function cover()
{
    return $this->morphMany('Image', 'imageable');
}

public function delete()
{
   $this->posts()->comments()->delete();

    $this->posts()->delete();

    $this->cover()->delete();
    // delete the model
    return parent::delete();
}

function book() {
    return $this->belongsTo('Book');
}

function comments() {
    return $this->hasMany('Comment');
}

function user() {
    return $this->belongsTo('User');
}

public function delete()
{
    $this->comments()->delete();
    // delete the model
    return parent::delete();
}

function post() {
    return $this->belongsTo('Post');
}

function user() {
    return $this->belongsTo('User');
}

}

models/Post.php

班上的帖子很有说服力{

function posts() {
    return $this->hasMany('Post');
}

function user() {
    return $this->belongsTo('User');
}

public function cover()
{
    return $this->morphMany('Image', 'imageable');
}

public function delete()
{
   $this->posts()->comments()->delete();

    $this->posts()->delete();

    $this->cover()->delete();
    // delete the model
    return parent::delete();
}

function book() {
    return $this->belongsTo('Book');
}

function comments() {
    return $this->hasMany('Comment');
}

function user() {
    return $this->belongsTo('User');
}

public function delete()
{
    $this->comments()->delete();
    // delete the model
    return parent::delete();
}

function post() {
    return $this->belongsTo('Post');
}

function user() {
    return $this->belongsTo('User');
}

}

models/Comment.php

类注释扩展了雄辩的{

function posts() {
    return $this->hasMany('Post');
}

function user() {
    return $this->belongsTo('User');
}

public function cover()
{
    return $this->morphMany('Image', 'imageable');
}

public function delete()
{
   $this->posts()->comments()->delete();

    $this->posts()->delete();

    $this->cover()->delete();
    // delete the model
    return parent::delete();
}

function book() {
    return $this->belongsTo('Book');
}

function comments() {
    return $this->hasMany('Comment');
}

function user() {
    return $this->belongsTo('User');
}

public function delete()
{
    $this->comments()->delete();
    // delete the model
    return parent::delete();
}

function post() {
    return $this->belongsTo('Post');
}

function user() {
    return $this->belongsTo('User');
}

}

但是在我的

UserController.php

中，我无法访问我的评论。我尝试了以下代码：

这总是说：

---

如何访问我在帖子下的评论？而且我不认为

$this->posts（）->comments（）->delete（）不起作用。
在您的
用户
模型中添加如下关系：

// User model
public function books()
{
    return $this->hasMany('Book');
}

然后在您的
控制器中
：

public function show($id)
{
    // User->hasMany:books->hasMany:posts->hasMany:Comments
    $user = User::with('books.posts.comments')->find($id);
    return View::make('viewName')->with('user', $user);
}

然后在
视图中
：

{{ $user->nameMaybe }}
{{ $user->emailMaybe }}
@foreach($user->books as $book)
    {{ $book->title }}
    {{ $book->author }}
    @foreach($book->posts as $post)
        {{ $post->slugMaybe }}
        {{ $post->postTitleMaybe }}
        @foreach($post->comments as $comment)
            {{ $comment->commenttextMaybe }}
        @endforeach
    @endforeach
@endforeach

返回的
用户
模型的结构如下（根据您的关系）：

您是否试图只获取特定用户的评论？在我的
User
model:
public function books（）{return$this->hasMany（'Book'）；}
已经存在，让我用控制器试试。
return View:：make（'viewName'）->with（'Book'，$Book）显示：未定义变量：bookSo，您在
用户
模型中有
书籍
？哎呀！我的错误是，它必须是
with（'user'，$user）
而不是
with（'book'，$book）
：-）试试这个
$user=user:：with（'books.posts'=>函数（$postsQuery:：with（'comments'=>函数（$commentsQuery）{$commentsQuery->orderBy（'created_at'，'desc'）））->orderBy（'created_at'，'desc'））->find（$id）。
