问题 I'm building a time tracker and i'm trying to fill up a table with the total time logged for each category type for each month of the year. I'm not sure what i'm doing wrong but my table isn't showing any data. I believe it has to do with the way i'm calling my rows, each number represents the category_id, ex: <td>{{ $row[1] ?? '-' }}</td> This is supposed to be using the total time from category_id 1 which is Overtime Hours. Here's more info to make things more clear. Controller: public

问题 This strange thing is happening to me.I have the code below : $state_image =States_Images::where('id_state', $id); echo $delete_path=$state_image->name; and the result is : Undefined property: Illuminate\Database\Eloquent\Builder::$name Someone help me pls :( 回答1: You need to finish the query with get() or first().

问题 I am using Laravel 5.1 and have a multi-tenancy database setup using a trait and scope as below. How can I add to this so that all insert queries also get the cust_id parameter injected? Scope: <?php namespace App\Scopes; use Illuminate\Database\Eloquent\Model; use Illuminate\Database\Eloquent\Builder; use Illuminate\Database\Eloquent\ScopeInterface; use App\Customers; use DB, Session; class MultiTenantScope implements ScopeInterface { /** * Create a new filter instance. * * @param UsersRoles

问题 I have a Laravel app where i'm using jQuery DataTables Master/Details to show some extra information. I can show the data to the child row, but I want it filtered first, depending on the row selected. The information that i want to retrieve is not on the original data source which I used to create the DataTable. Therefore i want to pass the record id to the new query that I am using directly from the javascript. Here is the code: function kpi_values(d) { // `d` is the original data object for

问题 Consider this code: Articles ::select('article_id', 'article_text') //This one does not work as expected ->with([ 'user' => function($q){ $q->select('user_id', 'user_name'); // This one works fine } ]) ->get(); When building query in Eloquent, we can use ->with() to retreive associated models. We can also attach ->select(), to determine which columns should be selected from associated model. However, looks like we loose possibility to specify which columns should be selected from the base

问题 I am trying to run an Eloquent model to insert data to the database, I tried to run a test run using Laravel schedule and cronjobs, below is my code This is my App\Console\kernel.php protected $commands = [ 'App\Console\Commands\test', ]; /** * Define the application's command schedule. * * @param \Illuminate\Console\Scheduling\Schedule $schedule * @return void */ protected function schedule(Schedule $schedule) { $schedule->command('check:test')->everyMinute(); } And my App\Console\Commands

问题 There's a missing link I fail to understand. I use migrations to create database tables and I define the relationships there. meaning.. if I have a person table and a job table and I need a one to many relationship between the person and jobs, I'd have the job table contain a "person_id". When I seed data or add it in my app, I do all the work of adding the records setting the *_id = values etc. but somehow I feel Laravel has a better way of doing this. if I define that one to many

问题 I'm in the process of rewriting a REST service, and I've decided to go with Slim Framework and I'm using Eloquent ORM because it works best for me. Previously I have done my soft deletes with a column deleted and set it to either 1 or 0 for deleted or not. With Eloquent it sets a timsestamp to a column deleted_at , is there a way I can set it to my previous soft delete method of just setting deleted to 1? 来源： https://stackoverflow.com/questions/27910953/custom-soft-delete-column-and-value-for
