laravel-5.1

问题 I'm handling data in one controller and want to pass it further into another controller to avoid duplicate code. Is there a way to set up a Request object that is needed in the other controller's store -method? I've traced down the Request inheritance and came to Symfony's Request object which has a request property that is in fact a ParameterBag that holds a method add to add parameters with values to it. I've tried the following but I'm getting null as result: $myRequest = new Request();

问题 I was wondering what the difference is between the different command-like classes in Laravel 5.1. As far as I can tell Laravel 5.1 has the following available: Console commands ( artisan make:console ) Commands ( artisan make:command ) Handlers ( artisan make::command --handler ) Jobs ( artisan make:job ) I have come straight from 4.2 to 5.1 so I don't know what happened in between 4.2 and 5.1, but I have been told that the middle one ( just commands) are basically not really supposed to be

问题 I have a set of delete statements in my Laravel 5.1 application that I have put inside a transaction. I had my code like the following and was trying to return to the same page.

问题 I am looking for something which can be like findOrDo(). Like do this when data not found. Something could be like Model::findOrDo($id,function(){ return "Data not found"; }); Is there any similar thing in laravel that I can do this elegantly and beautifully ? *I tried googling but could not find one 回答1: use Illuminate\Database\Eloquent\ModelNotFoundException; // Will return a ModelNotFoundException if no user with that id try { $user = User::findOrFail($id); } // catch(Exception $e) catch

问题 I'm trying to get the total size of $directory in Laravel, so far I've only been able to get the size of a single file using the size function. There doesn't seem to be any examples or documentation of this? Any input on this would be appreciated, thanks. 回答1: I don't think you can. Laravel 5 uses Flysystem Library, which has a sole method for retrieving file size. So using Laravel's File Facade (or Flysystem), you're only left with: $file_size = 0; foreach( File::allFiles('FULL_PATH_TO_DIR')

问题 Is there a way to retrieve a model in Laravel with all the attributes, even if they're null? It seems to only return a model with the attributes that aren't null. The reason for this is that I have a function that will update the model attributes from an array, if the attributes exists in the model. I use the property_exists() function to check the model if it has a particular attribute before setting it. The array key and model attribute are expected to match, so that's how it works. It

问题 Any ideas why the session variable is not set with this code ? public function commitTransaction($cluster,$transId) { try { $response = $this->client->request('PUT', 'https://' . $cluster . '/' . $transId, [ 'auth' => ['id', 'pass'], 'proxy' => '', 'verify' => false, 'json' => [ 'state' => 'VALIDATING' ] ]); $res = $response->getBody()->getContents(); session()->put('commit',$res); //dd($res); return $res; } catch (RequestException $e){ var_dump($e->getResponse()->getBody()->getContents()); }
