Laravel Model tutorials

create a laravel project for my table spends with columns 

id bigint autoincre 

 date date 

description varchar(150) 

amount float. Use Model, migration, controller with all resources and views.

Solution:

Create the Migration: Use the make:migration command to create a migration file for the spends table:

php artisan make:migration create_spends_table
 

Define the Schema: Open the generated migration file in database/migrations and define the schema for the spends table:

 

// database/migrations/xxxx_xx_xx_xxxxxx_create_spends_table.php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateSpendsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('spends', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->date('date');
            $table->string('description', 150);
            $table->float('amount');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('spends');
    }
}
 

Run the Migration: Apply the migration to create the spends table in your database:

php artisan migrate
 

Create the Model: Use the make:model command to create a model for the spends table:

php artisan make:model Spend
 

Define Fillable Attributes: Open the model file created in app/Models/Spend.php and define the fillable attributes:

// app/Models/Spend.php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Spend extends Model
{
    use HasFactory;

    protected $fillable = [
        'date',
        'description',
        'amount',
    ];
}

Define the Controller Methods: Open the generated controller file in app/Http/Controllers/SpendController.php and add the methods for CRUD operations:

// app/Http/Controllers/SpendController.php

namespace App\Http\Controllers;

use App\Models\Spend;
use Illuminate\Http\Request;

class SpendController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $spends = Spend::all();
        return response()->json($spends);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
            'date' => 'required|date',
            'description' => 'required|string|max:150',
            'amount' => 'required|numeric',
        ]);

        $spend = Spend::create($request->all());

        return response()->json($spend, 201);
    }

    /**
     * Display the specified resource.
     *
     * @param  \App\Models\Spend  $spend
     * @return \Illuminate\Http\Response
     */
    public function show(Spend $spend)
    {
        return response()->json($spend);
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Models\Spend  $spend
     * @return \Illuminate\Http\Response
     */
    public function edit(Spend $spend)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Models\Spend  $spend
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Spend $spend)
    {
        $request->validate([
            'date' => 'required|date',
            'description' => 'required|string|max:150',
            'amount' => 'required|numeric',
        ]);

        $spend->update($request->all());

        return response()->json($spend);
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Models\Spend  $spend
     * @return \Illuminate\Http\Response
     */
    public function destroy(Spend $spend)
    {
        $spend->delete();

        return response()->json(null, 204);
    }
}

Define the Routes: Open your routes file (typically routes/web.php for web routes or routes/api.php for API routes) and add the routes for the SpendController:

// routes/web.php or routes/api.php

use App\Http\Controllers\SpendController;

Route::resource('spends', SpendController::class);

Create the Blade View for Listing Data: Create a Blade view to list all the spends. Let's name it index.blade.php.
