Question

在这种情况下，我有患者模型和报告模型。患者有很多报告。

<?php

namespace App;  
use Illuminate\Foundation\Auth\User as Authenticatable;
use DB;
use Spatie\Permission\Traits\HasRoles;

class Patient extends Authenticatable
{
    public function reports()
    {
        return $this->hasMany('App\Reports');
    }
}

在一个视图中，我列出了所有患者的报告标签。我们有一个搜索患者模块，我们可以通过患者ID 和报告ID 搜索患者。我能够使用

满足患者ID 的搜索

$ data = Patient :: where（＆＃34; id＆＃34;，＆＃34; LIKE＆＃34;，＆＃34;％{$ search_patient}％＆＃34;）

但由于正在使用hasMany关系检索报告数据，因此无法解决基于报告ID 搜索患者和过滤结果的方案

以下是结果，其中患者数据来自患者模型，而报告数据来自使用hasMany关系的Reports模型。我的要求是当我使用报告ID进行搜索时，我应该只能看到具有该报告ID和用户信息的数据。

[
  {
    "id": 1,
    "group_id": 1000,
    "date": "01-01-14",
    "name": "Voss",
    "address": "My Home 1",
    "reports": [
      {
        "id": "ABC123",
        "name": "Report1"
      },
      {
        "id": "EDC123",
        "name": "Report2"
      }
    ]
  },
  {
    "id": 2,
    "group_id": 1000,
    "date": "01-01-15",
    "name": "Rosalia",
    "address": "My Home 2",
    "reports": [
      {
        "id": "RTC123",
        "name": "Report3"
      },
      {
        "id": "TYH123",
        "name": "Report4"
      }
    ]
  }
]

Answer 1

为您的报告模型添加belongsTo关系，如下所示：

public function patient() {
    return $this->belongsTo("App\Models\Patient", "patient_id", "id");
}

然后在报告模型中执行搜索

$data = Report::with('patient')->where('id', $report_id)->get();

结果应如下所示

...
{
  "id": ABC123,
  "name": Report 1,
  "patient": {
    "id": 2,
    "group_id": 1000,
    "date": "01-01-15",
    "name": "Rosalia",
    "address": "My Home 2",
  }
},
...

修改的：如果您坚持以患者为基础，请执行以下操作：

 Patient::whereHas('reports', function ($query) use($report_id) {
     $query->where('id', $report_id);
 })->with(['reports' => function ($query) use($report_id) {
     $query->where('id', $report_id);
 }])->get();

whereHas将执行搜索
只会急切加载您指定的报告ID

Answer 2

首先在报表模型中添加belongsTo：

public function patient()
{
    return $this->belongsTo(Patient::class);
}

然后像这样检索它：

$reportId = "ABC123"; //for demo purposses, you get this dynamically

$record = Report::where('record_id', '=', $reportId)->first();
    // i used record_id, but you probably have just id;

$patient = $record->patient()->with('records')->first();

dd($patient);

结果是：

Patient {#199 ▼
  #guarded: []
  #connection: "mysql"
  #table: null
  #primaryKey: "id"
  #keyType: "int"
  +incrementing: true
  #with: []
  #withCount: []
  #perPage: 15
  +exists: true
  +wasRecentlyCreated: false
  #attributes: array:5 [▼
    "id" => 1
    "group_id" => 1000
    "date": "01-01-15"
    "name" => "Rosalia"
    "created_at" => null
    "updated_at" => null
  ]
  #original: array:5 [▶]
  #changes: []
  #casts: []
  #dates: []
  #dateFormat: null
  #appends: []
  #dispatchesEvents: []
  #observables: []
  #relations: array:1 [▼
    "reports" => Collection {#204 ▼
      #items: array:2 [▼
        0 => Report {#207 ▶}
        1 => Report {#209 ▶}
      ]
    }
  ]
  #touches: []
  +timestamps: true
  #hidden: []
  #visible: []
  #fillable: []

根据模型中关系的数据过滤搜索结果
