How to create a page

Route

Set Route - routes/web.php

Route::get('about-us','PageController@aboutUs')

Controller

Create a controller - php artisan make:controller PageController --resource - and create a method aboutUs returning view from pages.index.

public function aboutUs()
{
	return view('pages.index');
}

View

Create the view - create new folder in resources/views/ named pages. In pages, create aboutUs.blade.php. Add the following content:

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row">
		<h1>About Us</h1>
    </div>
</div>
@endsection

How to create a list of users using Artisan

Run php artisan tinker.

Then run factory(\App\User::class, 100)->create();. This will create 100 users.

How to call PUT and DELETE from Ajax

You need to method spoofing when calling PUT and DELETE method in Laravel since HTTP call does not capture other that GET and POST. Following are the sample code when you need to call a PUT or DELETE URI using Ajax.

function confirmDelete(id)
{
	if(confirm('Are you sure'))
	{
		var data = {
			_token : window.Laravel.csrfToken,
			_method : 'delete'
		}
		$.post('/users/' + id, data, function(data, textStatus, xhr) {
			// do something
		});
	}
}

How to create a validator

Create custom request by running php artisan make:request UserRequest.

Open UserRequest.php located at app/Http/Requests.

Add validation rules for your form at rules() method:

return [
    'name' => 'required|min:6|max:255',
    'email' => 'required|email|max:255|unique:users',
    'password' => 'required|min:6|confirmed',
];

Next, include UserRequest namespace in UserController - use App\Http\Requests\UserRequest;.

Now in UserController's store(Request $request) method, replace store(Request $request) with store(UserRequest $request).

To display error message

Following are the sample to display an error message

@if ($errors->has('email'))
    <span class="help-block">
        <strong>{{ $errors->first('email') }}</strong>
    </span>
@endif

Authorization

You may return to true in UserRequest's authorize() method if there's no particular authorization required.

public function authorize()
{
    return true;
}

Validation from within Controller

$this->validate($request, [
    'name' => 'required|min:6|max:255',
    'password' => 'required|min:6|confirmed',
]);

How to create a model and migration script together?

Just run following command:

php artisan make:model Post -m

This will create a model named Post.php in app folder and a migration script timestamp_create_posts_table.php in database\migrations folder.

Read more about Creating Columns

After done adding columns, run php artisan migrate to run the migration script and have your tables in database.

How to create model factory

Open up database\factories\ModelFactory.php and copy the user's factory and update as following:

$factory->define(App\Post::class, function (Faker\Generator $faker) {
    
    return [
        'title' => $faker->sentence,
        'description' => $faker->text
    ];
});

How to create seeder file and seed the data

Create a seeder file using following command:

php artisan make:seeder PostTableSeeder

Open PostTableSeeder.php located at database\seeds folder and call the factory for Post, as following in run method:

factory(\App\Post::class, 100)->create();

How to call seeder file

Open up database\seeds\DatabaseSeeder.php and call the PostTableSeeder as following:

public function run()
{
    $this->call(PostTableSeeder::class);
}

How to seed data

Run php artisan db:seed
