laravel-4

问题 Here's a tricky question. I am building a framework in Laravel and I want my objects to interact with Rackspace in a transparent way. From now on I made it possible to upload/delete objects without having in mind Rackspace $model->file = Input::file('thing'); // and it uploads to Rackspace. The next step I want to achieve is to get the route using my config file. The behaviour would be something like $route = $file->source (with source with hello.jpg in the database for instance) and get

问题 I am in the process of migrating from L3 to L4. When registering the HomeController controller that came with the default L4 installation, trying to go to the page www.domain.com/home gives me a ResourceNotFound exception.

Did I miss out an additional step? routes.php Route::controller('home', 'HomeController'); controllers/HomeController.php <?php class HomeController extends BaseController { public function showWelcome() { return View:

问题 I have no qlue why I can't get the following to work: DB::table('twitter_hashtags')->paginate(5); Every single time I get (the second number tends to differs) Allowed memory size of 134217728 bytes exhausted (tried to allocate 95735352 bytes) I tried using as in (18776710), but that did not make any difference DB::connection()->disableQueryLog(); Removing ->paginate(5) does not make any difference.

问题 Suppose I have 3 tables. Images Subject Style The relationship is Many to Many(Images,Subject) and Many to Many(Images,Style). Now I want to do something like: $result=$subjectResult->images()->merge($styleResult->images()) . I want the type of result to be an Images Collection Object. So far I've tried it as: $subjectResult=Subject::with('images')->where(query)->get(); But this returns the subject rows,Image rows and the pivot rows. I want to extract the Images collection from it.

问题 I am developing both a blog with wordpress and a rather complex application with laravel. The problem is to integrate one in the other. I do not want the users to need to log into both services seperately. As I need to store more information about a user than just the wordpress basics I want to use Eloquent and everything from Laravel though. I could include the Wordpress core and just use the wordpress authentication, but that would mean to load the whole WP environment everytime, if I am

问题 I am relatively new to Laravel, but I would like to restrict account access so that only one account can be logged into at one time. For example, if I were to log into my account on my work computer and then I logged in at my home computer simultaneously, it would not log me in and prompt me to logout of the first computer. What is the best and correct way of doing this? Many Thanks 回答1: This is more a 'logic' question than one about Laravel. In short I would build something like this; Add a

问题 It seems I'm not the only person struggling with the differences between Laravel's DB::raw(), DB::select(), DB::statement(), and DB::unprepared() methods. It seems as if one almost needs to try a given SQL statement with all 4 to identify which will work. Can anybody clarify how they relate to each other, and which to use for what purposes? 回答1: I will try to clarify: DB::raw() It generates a raw and sanitized SQL string, to be passed to other query/statements, preventing SQL injections.

问题 I am running a laravel 4 framework and I get a Whoops! error with just the message "_token" when I try to update an instance of an eloquent model class. What does this mean? I use Form::model to create the form and I am able to update records of other model classes. 回答1: This is usually a result of either a missing or mismatched CSRF token.
