Query Builder (Model)
✔ SELECT
✔
$users = DB::table('users')->get();
✔ INSERT
✔ $id = DB::table('user')
->insertGetId(array('email' =>'nikhila@mindfire.com',
'password' => 'mindfire'));

->delete();
Presenter: Nikhil Agrawal, Mindfire Solutions

13. 13
Eloquent ORM (Model)
✔ Defining a Eloquent model
✔ Class User Extends Eloquent { }
✔ Try to keep the table name plural and the respective model as singular (e.g
users / User)
✔ SELECT
✔ $user = User::find(1) //Using Primary key
✔ $user = User::findorfail(1) //Throws ModelNotFoundException if
no data is found
✔ $user = Menu::where('group', '=', 'admin')->remember(10)->get();
//Caches Query for 10 minutes
✔ INSERT
✔ $user_obj = new User();
$user_obj->name = 'nikhil';
$user_obj->save();
✔ $user = User::create(array('name' => 'nikhil'));

Loops
View Composer
✔ View composers are callbacks or class methods that are called when
a view is rendered.
✔ If you have data that you want bound to a given view each time that
view is rendered throughout your application, a view composer can
organize that code into a single location
View::composer('displayTags', function($view)
{
$view->with('tags', Tag::all());
});
Presenter: Nikhil Agrawal, Mindfire Solutions
