Table management for the project in laravel is the primary question for the developer as especially when you are working with a parent-child relationship like categories and its child categories. So how do you manage that table with two separate tables one for the main category and the second for the sub-category? I suggest you to NO you can also manage this parent-child relationship in single table.
So you can max usage of the table and proper management of parent and child relationship in a single table. There is no need to create two separate tables for it.
In this example, I will tell you how to manage category and sub-category (parent, child) relationship in a single table and how to fetch it as we fetch data while we have to tow separate tables.
Output Preview :

You can see in the category listing table name of all the table categories and if the category is a sub-category then in the left side table column its parent category name also will show you.
Migration :
This is my migration file, this is you can see how I manage my category table. if category_id will have null then it will main category. Then category_id stored then it will be sub-category which given category_id'
Also, it should nullable because it's the store's main category. Definitely will have value if the sub-category you are storing.
database/migrations
<?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; use Illuminate\Support\Facades\Schema; class CreateCategoriesTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('categories', function (Blueprint $table) { $table->id(); $table->string('name'); $table->tinyInteger('status')->default(1)->comment('1 active,2 deactive'); $table->tinyInteger('category_id')->nullable(); $table->text('description')->nullable(); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('categories'); } }
Also, I have given category status that will be inactive if the status will be 2 and active for status 1.
Category Model
In this example, I just made a relationship in the eloquent model using belongsTo method.
Have you noticed? Category model i belongsTo i have relationship in Category same model. So I can fetch that category parent or main category of it.
So when you will fetch the data in a relationship the parent name is also alive.
<?php namespace App\Models; use Illuminate\Database\Eloquent\Model; class Category extends Model { protected $fillable = [ 'name', 'status', 'category_id', 'description' ]; public function category() { return $this->belongsTo(Category::class,'category_id','id'); } }
CategoryController
Using with i am fetch the parent category relationship and print out it. And then just given simple paginate of ten.
app\Http\Controllers\CategoryController.php
<?php namespace App\Http\Controllers; use App\Models\Category; use Illuminate\Http\Request; class CategoryController extends Controller { /** * Display a listing of the resource. * * @return \Illuminate\Http\Response */ public function index() { $categories = Category::with('category')->paginate(10); return view('admin.category.category',compact('categories')); } }
I will compact my category to my blade file. This is a category with uses compact function.
Dashboard.blade.php
<div class="box"> <div class="box-header with-border"> <div class="row"> <div class="col-md-4"> <h3 class="box-title">Category List</h3> </div> <div class="col-md-8 text-right"> <a class="btn btn-success float-right" href="{{ route('category.create') }}">Create</a> </div> </div> </div> <!-- /.box-header --> <div class="box-body"> <table class="table table-bordered text-center"> <tr> <th style="width: 10px">#</th> <th>Name</th> <th>Parent Category</th> <th>Status</th> <th>Created At</th> <th>Updated At</th> </tr> @foreach ($categories as $key => $category) <tr> <td>{{ $category->id }}</td> <td>{{ $category->name }}</td> <td>{{ isset($category->category->name) ? $category->category->name : '---' }}</td> <td> @if($category->status == 1) <span class="label label-success">Active</span> @else <span class="label label-danger">InActive</span> @endif </td> <td>{{ $category->created_at }}</td> <td>{{ $category->updated_at }}</td> </tr> @endforeach </table> </div> <div class="text-right paginate"> {{ $categories->links('pagination::bootstrap-4') }} </div> </div>
This is my blade file look at how I echo my parent category while we have the parent category of its child.
So this is simple to manage the child-parent relationship in a single table and fetch data also easy and simple to make for the developer project.
