laravel-4

问题 So typically if you have access to the id of a user in laravel you can run User::find($id), however say you don't have access to the user's id and only their username. Is there a better way than using DB::query to locate the user? This is my current solution and was wondering if someone possibly knew a better way. $user_id = DB::table('users')->where('username', $user_input)->first()->id; 回答1: Yes, even better using the model. just like this User::where('username','John') -> first(); // or

问题 I have a pivot table for a many to many relationship which includes a third index parameter for another model. I would like to be able to use Eloquent to access this model.

问题 I have a working Laravel application on my desktop. I am trying to deploy it to a godaddy server. The application has been copied and verified on the server in the same structure format as on my desktop. I have changed the database information in the config to the proper entries.

Again this app works locally, any idea why it errors when deployed?

问题 I'm writing an api in Laravel 4. I'd like to pass query string parameters to my controllers. Specifically, I want to allow something like this: api/v1/account?fields=email,acct_type where the query params are passed along to the routed controller method which has a signature like this: public function index($cols) The route in routes.php looks like this: Route::get('account', 'AccountApiController@index'); I am manually specifying all my routes for clarity and flexibility (rather than using
