Question

我正在使用laravel，在下面的演示中，出现了问题，数据无法在视图中显示：

演示：

article.blade.php

@foreach ($articles as $article)
  {{$article}}
@endforeach

导致浏览器：

{"id":1,"title":"hello world","content":"demo","created_at":"2017-07-23 15:34:52","updated_at":"2017-07-23 15:34:55"}

但它有以下错误：

article.blade.php

@foreach ($articles as $article)
  {{$article->title}}
@endforeach

错误：

Property [title] does not exist on this collection instance.

为什么会这样？

更新

dd($articles)的结果：
我需要这个数据结构，不要修改它，外部数组可以被mofidied到一个集合。

array:2 [▼
  0 => Collection {#485 ▼
    #items: array:6 [▼
      "id" => 1
      "title" => "hello"
      "content" => "hello world"
      "user_id" => 2
      "tags" => Collection {#505 ▼
        #items: array:2 [▼
          0 => Tag {#506 ▶}
          1 => Tag {#508 ▶}
        ]
      }
      "created_at" => "2017-07-23 15:34:52"
      "updated_at" => "2017-07-23 15:34:55"
    ]
  }
  1 => Collection {#500 ▼
    #items: array:6 [▼
      "id" => 2
      "title" => "foo"
      "content" => "foo bar"
      "user_id" => 2
      "tags" => Collection {#505 ▼
        #items: array:2 [▼
          0 => Tag {#506 ▶}
          1 => Tag {#508 ▶}
        ]
      }
      "created_at" => "2017-07-23 16:27:43"
      "updated_at" => "2017-07-23 16:27:46"
    ]
  }
]

Answer 1

您可以尝试使用

@foreach ($articles as $a)
  {{$a->title}}
@endforeach

我知道这就像一个奇迹，但有时候，它就像一个魅力。
