获取所有必需数据的函数:
$auditResults = Audit::where('audit_id', $id)
->with('questionDetail')
->with('questionDetail.auditQuestion')
->get();
返回(流线型):
Audit {#427 ▼
#relations: array:1 [▼
"questionDetail" => AuditQuestionDetail {#449 ▼
#relations: array:1 [▼
"auditQuestion" => AuditQuestion {#471 ▼
#original: array:5 [▶]
}
]
}
]
}
对于每个 Audit，我如何在 View 中循环以达到 auditQuestion 关系？
我试过:
@foreach($auditResults->questionDetail->auditQuestion as $answer)
但是我得到:
Undefined property: Illuminate\Database\Eloquent\Collection::$questionDetail
非常感谢。
** 第一关系的问题:**
Collection {#470 ▼
#items: array:18 [▼
0 => Audit {#427 ▼
#fillable: array:4 [▶]
#attributes: array:7 [▶]
#original: array:7 [▶]
#relations: array:1 [▼
"questionDetail" => AuditQuestionDetail {#449 ▼
#table: "audit_questions_details"
#fillable: array:3 [▶]
#attributes: array:7 [▶]
#original: array:7 [▼
"id" => 2
"audit_question_id" => 2
"question_number" => 1
"comment" => 1
"header" => 0
"created_at" => "2017-03-26 13:40:18"
"updated_at" => "2017-03-26 13:40:18"
]
最佳答案
在 Laravel 5.4 中，你可以使用 higher order messages干净地做到这一点:
@foreach($auditResults->map->questionDetail->map->auditQuestion as $answer)
