Created model will be extended from a default Model.php class, which includes a bunch of default methods, review when necessary. Related docs

1. Create a Model boilerplate class

   php artisan make:model Article

2. Plugin for timestamps

   Carbon\Carbon::now();

3. Creating Model

   • Basic

     $article = new App\Article;

   • Pre-added values

     $article = App\Article::create(['title' => 'New Article', 'body' = > 'New body']);

   Remember Add fillable property inside related model class to avoid MassAssignment Exception and security breaches. In this case, inside the App/Article.php file

   protected $fillable = ['title', 'body'];

4. Saving Model

   $article->save();

5. Updating Model

   $article->update(['body' => 'Updated']);

6. Find a Model using id

   $article = App\Article::find(2);

7. Using scope to automatically set things by laravel. Define function in the following format set{AttributeName}Attribute({$data}). With the code body below

   $this->attributes['password'] = mcrypt($password);

8. Define relationship in model class, with a proper function name and a code body below

   return $this->hasMany('App\Article');

9. Using relationship for User to save an Article of it's own.

   \Auth::user()->articles()->save($article);

   Usually would need to get the User's id, but since it's already defined in the relationship, process would be automated

10. Many to many relationship between Article and Tag Use belongsToMany as the relationship type in the current Model

    public function {otherModel}s()
    {
        return $this->belongsToMany('App\{otherModel}');
    }

    Add code below into created migration file

    /**
     * Format :
     * {singularNameTableOne}_{singularNameTableTwo}
     * Ordered alphabetically
     */
    Schema::table('article_tag', function (Blueprint $table) {
        $table->foreign('article_id')
              ->references('id')
              ->on('articles')
              ->onDelete('cascade');
        $table->foreign('tag_id')
              ->references('id')
              ->on('tags')
              ->onDelete('cascade');
    });

    Hook them up using

    $article->tags()->attach({otherModelId})

    and vice versa

    $tag->articles()->attach({otherModelId})

Disable debug mode when in production. Change code below in .env

APP_DEBUG=false

Use Illuminate/Html package using Composer

composer require illuminate/html

Related docs

Tag open {!! Form::open() !!}, tag close {!! Form::close() !!}, CSRF tag added automatically using this tag.

Add code below into config\app.php file

1. in providers

   Illuminate\Html\HtmlServiceProvider::class,

2. in aliases

   'Form'      => Illuminate\Html\FormFacade::class,
   'Html'      => Illuminate\Html\HtmlFacade::class,

   Illuminate handles all form securities, NO SQL injection.

1. Do validation in server side using Request class

   php artisan make:request ArticleRequest

2. Insert code below into the rules() function

   return [
       'title'         => 'required|min:3',
       'body'          => 'required',
       'published_at'  => 'required|date',
   ];

3. Or use a simpler one just for little validation

   $this->validate($request, ['title' => 'required'])

1. Add middleware

   php artisan make:middleware RedirectIfNotAManager

1. Change code in RouteServiceProvider.php

   $router->model('articles', 'App\Article');

2. Remove any $id as parameter from function in ArticlesController.php, change into

   public function show(Article $article) {
       // remove the code in body : $article = Article::findOrFail($id);
   }

3. For complicated logic, change default in number 1 into

   $router->bind('articles', function($id) {
       return \App\Article::published()->findOrFail($id);
   });
