Creating a Model In Laravel.

Synatx : php artisan make:model ModelName

Let's create a model for Product

So we in the terminal write PHP artisan make: model Product

Writing a factory in Laravel.

By using the factory we can generate some fake data for the testing

<?php

/** @var \Illuminate\Database\Eloquent\Factory $factory */

use App\Product;
use Faker\Generator as Faker;

$factory->define(Product::class, function (Faker $faker) {
    return [
        'name' => $faker->name, // generate a random name 
        'brand'=>$faker->randomElement, //generate a random elemtn
        'description'=> $faker->text, // bunch of text
        'hsn'=> $faker->numberBetween($min = 1000, $max = 9000), 
// number between 1000 -90000                                                                  to 9000
        'tax'=> $faker->randomElement(['18%','12%','5%','NILL','28%'])                   
// pic a value from this array 
    ];

});.

Creating a factory in laravel

Command: PHP artisan make: factory FactoryName

ex: PHP artisan make: factory ProductFactory or you can make it during creating Model

PHP artisan make: model ModelName --all (it creates a model, controller, factory, seeder, and migration)

in this case, we are creating a factory for Product so we put Product in the place of the model name

D:\www\crm (main)

λ php artisan make: factory RolesFactory --model=Role

Factory created successfully.

It generates a blank factory file

Create a controller in laravel.

To create a controller using the syntax:

λ php artisan make: controller ControllerName

Creating some function which returns a string or a view.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PagesController extends Controller
{

    public function root()
    {
        return view('welcome'); //return a view 
    }

    public function about()
    {

        $name ="Dev"; // declaring a varibale and assigning a value to the varibale 

        return view ('about')->with('name', $name); // passing data to the view 
                                                      with ('name ', $varibale)
    }


    public function contact()
    {
        
        return 'contact'; //return a string
    }
}

let's check the route as well as how we define the routes?

 Route::get('/', 'PagesController@root');
 Route::get('contact', 'PagesController@contact');
 Route::get('about', 'PagesController@about');

so when you hit localhost:8000 (port may differ as per your config) this will return 
Welcome page 

let's create a welcome page first so go to the view directory create a file 
welcome.blade.php by default this page generated during installation so you can simply
edit the page as per your choice. 

 <div class="title m-b-md">
    Welcome to code factory 20-21 
 </div>

How to pass data to the view from the route in Laravel ??

We can pass the data to the view using help function

with ( )
compact ( )

Using With

Route::get('/greet', function () {
   $name = 'Dev';
    // declaring and assigning a value to the variable 
    return view ('greeting')->with('name', $name); // pass the variable to the view 
});

how to define a route ??

locate the route file web.php in side the route directory of the project

Basic Route which returns a value

Route::get('/greeting', function () {
    return 'good morning';

Basic Route which returns a view

Route::get('/greeting', function () {

To return a view we need to create  a view first other wise it throw an error view not found
 To create a view locate the view folder and create a file greeting.blade.php
