How to debug/view SQL requests with Laravel / Laragon - laravel

Question

My question is very simple but I have no clue: I have always been working with java and eclipse or C# until now so it's a "new world" :)
How can I debug my laravel code?
I am using laravel and vuejs. I start my server with laragon, and I use VScode. I have tried starting it from VScode (added xdebug dll in laragon) but it doesn't give me more info, and I don't manage to debug anything using breakpoints:
{
"name": "Launch localhost",
"type": "chrome",
"request": "launch",
"url": "http://127.0.0.1/",
"webRoot": "C://laragon//www//projet"
},
{
"name": "Launch index.php",
"type": "chrome",
"request": "launch",
"file": "C://laragon//www//projet//index.php"
},
When I get an error with sql, all I get is
app.js:651 Uncaught (in promise) Error: Request failed with status code 500
at createError (app.js:651)
at settle (app.js:814)
at XMLHttpRequest.handleLoad (app.js:184)
How can I see my SQL request and get the "real error"?
And how can I properly debug?
Thanks a lot in advance.

Answer 1

You have multiple options to achieve the SQL logging:
1.Use query listener by registering it in service provider (boot method as follow)
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use DB;
use Log;
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
Schema::defaultStringLength(191);
DB::listen(function($query) {
Log::info(
$query->sql,
$query->bindings,
$query->time
);
});
}
}
Use Query logging please refer to https://laravel.com/docs/5.0/database#query-logging
Use laravel debugger package please refer to https://github.com/barryvdh/laravel-debugbar
You can debug php with xdebug but i would still prefer any option among above 3.

Answer 2

You can use Laravel Debugbar to see the real time queries. It provides many other useful information for debugging purpose. Please check this link https://github.com/barryvdh/laravel-debugbar
Also try to log the collection into SQL using query listener by registering it inside service provider:
<?php
namespace App\Providers;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Log;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
DB::listen(function ($query) {
// $query->sql
// $query->bindings
// $query->time
Log::useDailyFiles(storage_path().'/logs/query_log.log');
$query = $query->sql;
Log::info($query);
});
}
/**
* Register the service provider.
*
* #return void
*/
public function register()
{
//
}
}
