问题 I think the title says it: I want to use ISO 8601 with timezones as default DateTime-Format in Laravels Eloquent. I got this class mEloquent extends Eloquent { protected function getDateFormat() { return 'YYYY-MM-DDThh:mm:ss.sTZD'; } } All my models will extend mEloquent. But how should I build the tables? Just <?php use Illuminate\Database\Migrations\Migration; use Illuminate\Database\Schema\Blueprint; class CreateUsersTable extends Migration { /** * Run the migrations. * * @return void */

问题 I have a query that searches for a term in several columns and one of them has to be a full name. I have separated the full name in name and lastname, so I have to concat these 2 values when searching. I have this right now only searching for name. How I would add the concat to lastname? I was investigating over mutators but I don't know if it is the way to way. public function search($searchQuery) { $search = "%{$searchQuery}%"; return Order::with('customer') ->orWhereHas('customer',

问题 I am working with Laravel 5 and I am having issue getting ->wherePivot() to work on a Many-to-Many relationship. When I dd() the SQL it looks like Eloquent is looking for records in the pivot table with a `pose_state`.`pose_id` is null`. I am hoping it is a simple error and not a bug. Any ideas are appreciated.

问题 I would like to execute the follow sentence using laravel eloquent SELECT *, count(*) FROM reserves group by day The only solution occurs to me is to create a view in the DB, but I am pretty sure there is a way to do it in laravel way. 回答1: You could use this: $reserves = DB::table('reserves')->selectRaw('*, count(*)')->groupBy('day'); 回答2: As you wish to do it with Laravel Eloquent I assume you have a model name Reserve . In this case you can use this $reserve = Reserve::all()->groupBy('day'
