Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Create Model & Migration

Open project into terminal and run this command to create model and migration file.

$ php artisan make:model Student -m

It will create two files –

Model – Student.php at /app/Models folder
Migration file – 2022_04_04_145928_create_students_table.php at /database/migrations folder.

Open Migration file and write this complete code into it.

<?php

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

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('students', function (Blueprint $table) {
            $table->id();
            $table->string("name", 120);
            $table->integer("term1_marks");
            $table->integer("term2_marks");
            $table->integer("term3_marks");
            $table->integer("term4_marks");
            $table->text("remarks");
        });
    }

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

Open model file Student.php and write this complete code into it.

<?php

namespace App\Models;

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

class Student extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Back to terminal and run this command.

$ php artisan migrate

It will create students table inside database.

Create Data Seeder

Next,

Create a seeder file to seed some dummy data for table.

Run this command to terminal –

$ php artisan make:seeder StudentSeeder

It will create a file StudentSeeder.php at /database/seeders folder.

Open StudentSeeder.php and write this complete code into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

use Illuminate\Support\Facades\DB;

class StudentSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $faker = \Faker\Factory::create();

        for ($loop = 0; $loop < 5; $loop++) {

            DB::table("students")->insert([
                "name" => $faker->name(),
                "term1_marks" => $faker->numberBetween(45, 95),
                "term2_marks" => $faker->numberBetween(45, 95),
                "term3_marks" => $faker->numberBetween(45, 95),
                "term4_marks" => $faker->numberBetween(45, 95),
                "remarks" => $faker->randomElement(["Good", "Excellent", "Needs Improvement", "Better", "Poor"])
            ]);
        }
    }
}

Run Seeder File

Run this command to terminal.

$ php artisan db:seed --class=StudentSeeder

It will create test data into database table.

Create Controller

Next, we need to create a controller file.

$ php artisan make:controller StudentController

It will create a file StudentController.php at /app/Http/Controllers folder.

Open StudentController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

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

class StudentController extends Controller
{
    public function index()
    {
        $students = Student::all();

        $dataPoints = [];

        foreach ($students as $student) {

            $dataPoints[] = array(
                "name" => $student['name'],
                "data" => [
                    intval($student['term1_marks']),
                    intval($student['term2_marks']),
                    intval($student['term3_marks']),
                    intval($student['term4_marks']),
                ],
            );
        }

        return view("bar-graph", [
            "data" => json_encode($dataPoints),
            "terms" => json_encode(array(
                "Term 1",
                "Term 2",
                "Term 3",
                "Term 4",
            )),
        ]);
    }
}

Create Template File

Go to /resources/views folder and create a file with name bar-graph.blade.php

Open bar-graph.blade.php and write this complete code into it.
