Laravel 4: How to add scope to DB::table?

阅读更多关于 Laravel 4: How to add scope to DB::table?

With Eloquent models adding scopes is easy: public function scopeMyScope($query) { // Do stuff to that $query } But how to add scope to DB::table ? I use this query to get page views: $views = DB::table('page_views') ->where('id', $this->id) ->where('agent', 'NOT LIKE', '%bot%') ->count(DB::raw('distinct session, DATE(created_at)')); I also show the most popular pages etc with other queries, but with the same where conditions.

Test logged in user has correct id in Laravel 4

阅读更多关于 Test logged in user has correct id in Laravel 4

I'm trying to work out how to test that the logged in user in Laravel 4 can visit the correct user account. At the moment this is what is in my routes.php file. Route::get('user/{id}', array('before' => 'auth', function(){ // logged in user // but can visit any account!! })); How would I restrict this to so user/1 could only see the profile if that is the current logged in users id? Auth::user()->id Returns the logged in id to test against but I can't work out how to write a filter that checks it's equal to the {id} in the url. Please help! Thanks. Got some help through the Laravel irc channel

Struggling with an issue in Laravel 4, in a "contact" model edit form, I can get all fields current values except those from the multiple select which is to establish a relation with another model "company".

阅读更多关于 Laravel 4 - custom 404 error handling only for missing pages

问题 In Laravel 4.1 I want to redirect the user to my customised 404 page if the page is not exists. That's easy because I already have this: App::missing(function($exception) { return Redirect::to('error404', 303)->with(array('error' => array('url' => Request::url()))); } But the problem is that if any linked file (image, js, css, etc.) is missing on the page I don't get 404 error for that file, but this is showing on console: Resource interpreted as Image but transferred with MIME type text/html

Laravel - Artisan gives wrong base url

阅读更多关于 Laravel - Artisan gives wrong base url

My app/config/app.php has 'url' => 'http://dev.domain.com/something/somethingElse' Then I have a function that can be called from the application and also from an artisan command. But URL::route('myRoute') returns different results. When called from the application it returns http://dev.domain.com/something/somethingElse/myRoute , but in the artisan command http://dev.domain.com/myRoute . URL::to has same behaviour. Note: I do not have any other app.php file defined for other environments that could overwrite the global one. Any ideas why this happens ? Thanks! A Laravel-generated URL consists
