我是 Laravel 的初學者。我想加入一些表并將其顯示在資料表中，我正在使用 yajra 資料表。我有三個表，分別是區域、分支和分支經理。我的問題是我想在刀片視圖中顯示 Branch 表，但不是顯示 area_id 和 branch_manager_id，我希望它顯示Area Table 中的area_desc 和Branch Manager Table 中的branch_manager_name 。我不知道如何獲得它。
面積表
public function up()
{
Schema::create('area', function (Blueprint $table) {
$table->engine = 'InnoDB';
$table->bigIncrements('id');
$table->string('area_code')->unique();
$table->string('area_desc');
$table->timestamps();
});
}
分行經理表
public function up()
{
Schema::create('branch_manager', function (Blueprint $table) {
$table->engine = 'InnoDB';
$table->bigIncrements('id');
$table->string('branch_manager_name');
$table->string('branch_manager_contact_number');
$table->timestamps();
});
}
分支表
public function up()
{
Schema::create('branch', function (Blueprint $table) {
$table->engine = 'InnoDB';
$table->bigIncrements('id');
$table->string('branch_name');
$table->string('branch_address1');
$table->string('branch_address2');
$table->bigInteger('area_id')->unsigned();
$table->bigInteger('branch_manager_id')->unsigned();
$table->timestamps();
});
Schema::table('branch', function (Blueprint $table) {
$table->foreign('area_id')->references('id')->on('area')->onUpdate('cascade');
$table->foreign('branch_manager_id')->references('id')->on('branch_manager')->onUpdate('cascade');
});
}
區域模型
class Area extends Model
{
use HasFactory;
protected $table = 'area';
protected $fillable = [
'area_code',
'area_desc',
];
public function branch()
{
return $this->hasMany(Branch::class);
}
}
分行經理模式
class BranchManager extends Model
{
use HasFactory;
protected $table = 'branch_manager';
protected $fillable = [
'branch_manager_name',
'branch_manager_contact_number'
];
public function branch()
{
return $this->hasOne(Branch::class);
}
}
布拉克模型
class Branch extends Model
{
use HasFactory;
protected $table = 'branch';
protected $fillable = [
'branch_name',
'branch_address1',
'branch_address2',
'area_id',
'branch_manager_id',
];
public function area()
{
return $this->belongsTo(Area::class);
}
public function branchManager()
{
return $this->belongsTo(BranchManager::class);
}
}
對 Branch 資料表的 Ajax 請求
<script type="text/javascript">
$(function() {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
var table = $('.table-striped.first').DataTable({
processing: true,
serverSide: true,
ajax: "{{ route('settings.branch.list') }}",
columns: [{
data: 'branch_name',
name: 'branch_name'
},
{
data: 'branch_address1',
name: 'branch_address1'
},
{
data: 'branch_address2',
name: 'branch_address2'
},
{
data: 'area_id',
name: 'area_id'
},
{
data: 'branch_manager_id',
name: 'branch_manager_id'
},
{
data: 'action',
name: 'action',
orderable: true,
searchable: true
},
]
});
</script>
分支控制器
public function branch(Request $request)
{
$branches = Branch::latest()->get();
$areas = Area::latest()->get();
$branchManagers = BranchManager::latest()->get();
if ($request->ajax()) {
$data = Branch::latest()->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('action', function($row){
$btn = '<a href="javascript:void(0)" data-toggle="tooltip" data-id="'.$row->id.'" data-original-title="Edit" >Edit</a>';
$btn = $btn.' <a href="javascript:void(0)" data-toggle="tooltip" data-id="'.$row->id.'" data-original-title="Delete" ><i ></i></a>';
return $btn;
})
->rawColumns(['action'])
->make(true);
}
return view('admin.branch', compact('branches', 'areas', 'branchManagers'));
}
任何意見將不勝感激，謝謝
uj5u.com熱心網友回復：
在 BrachController.php 中
public function branch(Request $request)
{
if ($request->ajax()) {
$data = Branch::with('area','branchManager')->latest()->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('area_desc', function($row){
return $row->area->area_desc;
})
->addColumn('branch_manager_name', function($row){
return $row->branchManager->branch_manager_name;
})
->addColumn('action', function($row){
$btn = '<a href="javascript:void(0)" data-toggle="tooltip" data-id="'.$row->id.'" data-original-title="Edit" >Edit</a>';
$btn = $btn.' <a href="javascript:void(0)" data-toggle="tooltip" data-id="'.$row->id.'" data-original-title="Delete" ><i ></i></a>';
return $btn;
})
->rawColumns(['area_desc', 'branch_manager_name', 'action'])
->make(true);
}
return view('admin.branch');
}
在刀片
<script type="text/javascript">
$(function() {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
var table = $('.table-striped.first').DataTable({
processing: true,
serverSide: true,
ajax: "{{ route('settings.branch.list') }}",
columns: [{
data: 'branch_name',
name: 'branch_name'
},
{
data: 'branch_address1',
name: 'branch_address1'
},
{
data: 'branch_address2',
name: 'branch_address2'
},
{
data: 'area_desc',
name: 'area_desc'
},
{
data: 'branch_manager_name',
name: 'branch_manager_name'
},
{
data: 'action',
name: 'action',
orderable: true,
searchable: true
},
]
});
</script>
