Why Laravel still logging a NotFoundHttpException while all routes works?

阅读更多关于 Why Laravel still logging a NotFoundHttpException while all routes works?

All my registered routes are working. They display the view, yet on every request a NotFoundHttpException shows up in my log file. I'm using NGINX. Could it be my NGINX config? The error that is logged on every request (even though the view shows up): log.ERROR: exception 'Symfony\Component\HttpKernel\Exception\NotFoundHttpException' in /usr/share/nginx/www/example-staging/releases/20130815024541/vendor/laravel/framework/src/Illuminate/Routing/Router.php:1429 Stack trace: #0 /usr/share/nginx/www/example-staging/releases/20130815024541/vendor/laravel/framework/src/Illuminate/Routing/Router.php

Add item to select box with an Eloquent collection

阅读更多关于 Add item to select box with an Eloquent collection

I have a select box on a form which uses data that is listed from an Eloquent model (Laravel 4): $campuses = Campus::lists('name', 'id'); And the form: {{ Form::select('campus_id', $campuses) }} However, I would like to have the first option on the form be Select... so that when the user has not selected an option yet, the first option does not become the default. How can I prepend another option to the beginning of the Eloquent collection? I've tried something like: $campuses = array('Select...') . Campus::lists('name', 'id'); You could also do $campuses = array('' => 'Select...') + Campus:

Laravel - Check if @yield empty or not

阅读更多关于 Laravel - Check if @yield empty or not

问题 Is it possible to check into a blade view if @yield have content or not? I am trying to assign the page titles in the views: @section("title", "hi world") So I would like to check in the main layout view... something like: <title> Sitename.com {{ @yield('title') ? ' - '.@yield('title') : '' }} </title> 回答1: There is probably a prettier way to do this. But this does the trick. @if (trim($__env->yieldContent('title'))) <h1>@yield('title')</h1> @endif 回答2: In Laravel 5 we now have a hasSection

Laravel Custom Model Methods

阅读更多关于 Laravel Custom Model Methods

问题 Whenever I add additional logic to Eloquent models, I end up having to make it a static method (i.e. less than ideal) in order to call it from the model's facade. I've tried searching a lot on how to do this the proper way and pretty much all results talk about creating methods that return portions of a Query Builder interface.

How to handle User Registration via API Laravel

阅读更多关于 How to handle User Registration via API Laravel

I have being reading and watching some tutorials about API development in Laravel. I am new to API development entirely although I have used Laravel a bit. From all the tutorials I have gone through, they handled: login, get some data, update information, delete information, and even insert some information into the database. My problem is that none of this tutorials handle something like a user registration. Route::group(array('prefix' => 'api/v1', 'before' => 'auth.basic'), function() { Route::resource('users', 'UsersController'); Route::resource('messages', 'MessagesController'); }); From

阅读更多关于 Preventing Laravel adding multiple records to a pivot table

问题 I have a many to many relationship set up and working, to add an item to the cart I use: $cart->items()->attach($item); Which adds an item to the pivot table (as it should), but if the user clicks on the link again to add an item they have already added it creates a duplicate entry in the pivot table. Is there a built in way to add a record to a pivot table only if one does not already exist? If not, how can I check the pivot table to find if a matching record already exists? 回答1: You can

Laravel 4 blade templates causing FatalErrorException?

阅读更多关于 Laravel 4 blade templates causing FatalErrorException?

I'm getting an unexplained FatalErrorException when trying to implement a simple page layout using blade templating. I'm not sure if it's something I'm doing wrong or Laravel is. I'm following the tutorial on L4's documentation about Templating and my code seems to follow it. Here's my code. app/routes.php: <?php Route::get('/', 'HomeController@showWelcome'); app/views/home/welcome.blade.php: @extends('layouts.default') @section('content') <h1>Hello World!</h1> @stop app/views/layouts/default.blade.php: <!doctype html> <html> <head> <title>The Big Bad Barn (2013)</title> </head> <body> <div>
