Laravel 5.6 Mongodb crud tutorial with example for beginners

Laravel 5.6 Mongodb crud tutorial with example for beginners

MongoDB is an open-source, cross-platform, document-oriented NoSQL database used for high volume data storage. MongoDB is written in C++.

Using MongoDB with Laravel, We can use same eloquent functionality such as : first, all, get, take, skip, where, orWhere, whereIn, whereBetween, whereNull, orderBy, distinct etc.

In this Laravel MongoDB Tutorial, You will learn how to fetch records, insert, edit and delete the records.

For this example, I have used jenssegers/mongodb Package.

Step 1: Create MongoDB database

I assume that you have installed and configured mongodb database. You can also install mongodb by clicking the Install MongoDB Enterprise on Ubuntu.

Type mongo on the terminal to start with MongoDB shell.

>mongo

You will get following message on screen :

MongoDB shell version v3.6.5
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.5
Welcome to the MongoDB shell.
MongoDB Enterprise > use demodatabase
switched to db demodatabase

db.categories.insert( { "category": "PHP Tutorials", "slug": "php-tutorials" } )
Step 2: Install Laravel 5.6 Project

In this step, I will download the fresh Laravel application to start from the scratch.

composer create-project --prefer-dist laravel/laravel laravelmongodb
Step 3: Configure MongoDB Database

Now we will configure the database details to connect with MongoDB.

.env
MONGO_DB_HOST=127.0.0.1
MONGO_DB_PORT=27017
MONGO_DB_DATABASE=demodatabase
MONGO_DB_USERNAME=
MONGO_DB_PASSWORD=

Now we need to add array connection details on database.php config file. so let's add this way:

    ....
    'connections' => [
        ......
        'mongodb' => [
            'driver'   => 'mongodb',
            'host'     => env('MONGO_DB_HOST', 'localhost'),
            'port'     => env('MONGO_DB_PORT', 27017),
            'database' => env('MONGO_DB_DATABASE'),
            'username' => env('MONGO_DB_USERNAME'),
            'password' => env('MONGO_DB_PASSWORD'),
            'options'  => []
        ],


    ]

Step 4: Install Laravel MongoDB Package

In this step, I will install the jenssegers/mongodb package in our application.

composer require jenssegers/mongodb

Now register the MongodbServiceProvider in app.php within config directory.

    ....
    'providers' => [
        ....
        Jenssegers\Mongodb\MongodbServiceProvider::class,
    ]
    .....

Step 5: Create a Model

In this step, I will create a model by running following command :

php artisan make:model Category

Now update the "Model.php" with following line of code to establish models for corresponding collections.



namespace App;


use Jenssegers\Mongodb\Eloquent\Model as Eloquent;


class Category extends Eloquent
{
    protected $connection = 'mongodb';
    protected $collection = 'categories';


    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'category', 'slug'
    ];
}
Step 6: Add Route

In this step, I will add a resource route for crud operation.

routes/web.php
Route::resource('categories','CategoryController');
Step 7: Add Category Controller

In this step, I will create a "CategoryController.php" file to perform crud action.


namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Category;

class CategoryController extends Controller
{
    public function index()
    {
        $categories = Category::latest()->paginate(10);
        return view('categories.index',compact('categories'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }
    
    public function create()
    {
        return view('categories.create');
    }
   
    public function store(Request $request)
    {
        request()->validate([
            'category' => 'required'
        ]);
        $slug=str_slug($request->category);
        Category::create($request->all()+['slug'=>$slug]);
        return redirect()->route('categories.index')
                        ->with('success','Category created successfully');
    }
    
    public function edit(Category $category)
    {
        return view('categories.edit',compact('category'));
    }
   
    public function update(Request $request,Category $category)
    {
        request()->validate([
            'category' => 'required'
        ]);
        $slug=str_slug($request->category);

        $category->update($request->all()+['slug'=>$slug]);
        return redirect()->route('categories.index')
                        ->with('success','Category updated successfully');
    }
    
    public function destroy($id)
    {
        Category::destroy($id);
        return redirect()->route('categories.index')
                        ->with('success','Category deleted successfully');
    }
}
Step 8: Create Blade View File

To perform the crud activity, I need below files :

  • app.blade.php
  • index.blade.php
  • create.blade.php
  • edit.blade.php
resources/views/layouts/app.blade.php

    </div>
    @if ($message = Session::get('success'))
        <div class="alert alert-success">

            <th width="280px">Operation</th>
        </tr>
    @foreach ($categories as $category)
    <tr>
        <td>{{ ++$i }}</td>
        <td>{{ $category->category}}</td>
        <td>{{ $category->slug}}</td>
