return Redirect::action('[email protected]', array('key' => 'value'));

If intended redirect is not defined, defaults to foo/bar.

return Redirect::intended('foo/bar');

Route::get('foo', function(){});
Route::get('foo', 'Contr[email protected]');
Route::controller('foo', 'FooController');

RESTful Controllers

class User extends Model {
    protected $table = 'my_users';
}

More

Model::create(array('key' => 'value'));

Find first matching record by attributes or create

Model::firstOrCreate(array('key' => 'value'));

Find first record by attributes or instantiate

Model::firstOrNew(array('key' => 'value'));

Create or update a record matching attibutes, and fill with values

Model::updateOrCreate(array('search_key' => 'search_value'), array('key' => 'value'));

          ->where('name', '=', 'John')
          ->orWhere(function($query)
          {
              $query->where('votes', '>', 100)
                    ->where('title', '<>', 'Admin');
          })
          ->get();

Laravel Aggregates

$users = DB::table('users')->count();
$price = DB::table('orders')->max('price');
$price = DB::table('orders')->min('price');
$price = DB::table('orders')->avg('price');
$total = DB::table('users')->sum('votes');

DB::table('name')->remember(5)->get();
DB::table('name')->remember(5, 'cache-key-name')->get();
DB::table('name')->cacheTags('my-key')->remember(5)->get();
DB::table('name')->cacheTags(array('my-first-key','my-second-key'))->remember(5)->get();

Laravel Raw Expressions 

$users = DB::table('users')
                   ->select(DB::raw('count(*) as user_count, status'))
                   ->where('status', '<>', 1)
                   ->groupBy('status')
                   ->get();

return rows

DB::select('select * from users where id = ?', array('value'));

return nr affected rows

DB::insert('insert into foo set bar=2');
DB::update('update foo set bar=2');
DB::delete('delete from bar');

returns void

DB::statement('update foo set bar=2');

raw expression inside a statement

DB::table('name')->select(DB::raw('count(*) as count, column2'))->get();

Laravel Inserts / Updates / Deletes / Unions / Pessimistic Locking

Inserts

DB::table('users')->insert(
  ['email' => '[email protected]', 'votes' => 0]
);
$id = DB::table('users')->insertGetId(
  ['email' => '[email protected]', 'votes' => 0]
);
DB::table('users')->insert([
  ['email' => '[email protected]', 'votes' => 0],
  ['email' => '[email protected]', 'votes' => 0]
]);

Updates

DB::table('users')
          ->where('id', 1)
          ->update(['votes' => 1]);
DB::table('users')->increment('votes');
DB::table('users')->increment('votes', 5);
DB::table('users')->decrement('votes');
DB::table('users')->decrement('votes', 5);
DB::table('users')->increment('votes', 1, ['name' => 'John']);

Deletes

DB::table('users')->where('votes', '<', 100)->delete();
DB::table('users')->delete();
DB::table('users')->truncate();

Unions. The unionAll() method is also available, and has the same method signature as union.

$first = DB::table('users')->whereNull('first_name');
$users = DB::table('users')->whereNull('last_name')->union($first)->get();

Pessimistic Locking

DB::table('users')->where('votes', '>', 100)->sharedLock()->get();
DB::table('users')->where('votes', '>', 100)->lockForUpdate()->get();

Validator::make(
    array('key' => 'Foo'),
    array('key' => 'required|in:Foo')
);
Validator::extend('foo', function($attribute, $value, $params){});
Validator::extend('foo', '[email protected]');
Validator::resolver(function($translator, $data, $rules, $msgs)
{
    return new FooValidator($translator, $data, $rules, $msgs);
});
