I want to log query and get it's sql so I tried:
DB::enableQueyLog();
Auth::user()->books();
dd(DB::getQueryLog());
but I get error:
Call to undefined method Illuminate\Database\MySqlConnection::enableQueyLog()"
also tried what suggested in laravel 5.8 docs but nothing get output to screen and when I open the log file there is no sql in it.
please how to log the query and get it is raw sql?
Update:
I have tried to do the following:
in AppServiceProvider.php
namespace App\Providers;
use Illuminate\Support\Facades\File;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\DB;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
//
DB::listen(function ($query) {
$query->sql;
$query->bindings;
// $query->time
});
}
}
and in my controller:
Auth::user()->books();
dd(DB::getQueryLog());
now I get:
[]
and no sql command that is executed.
please kindly help me
You misspelled the method name.
DB::enableQueryLog();
Please first enable query log using below code
DB::connection()->enableQueryLog();
then after you can use below method
$queries = DB::getQueryLog();

I'm working on my application using Laravel 7. I have used View Composer in my AppServiceProvider to get the count for a number of items in my database table. I have used where clause to get count for a specific logged in user. The problem is that I'm not sure how I can get the ID of currently logged in User and use in my AppServiceProvider. I have tried doing it but I'm getting Undefined variable: userId error. Please help. Thanks.
AppServiceProvider:
<?php
namespace App\Providers;
use App\Models\Project;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;
use Illuminate\Support\Facades\Auth;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
$userId = Auth::id();
View::composer('client_panel.layouts.menu', function ($view) {
$view->with('newprojects', Project::where([
['status','=','1'],
['created_by','=', $userId]
])->count());
});
}
}
The error is because of , you cant call outside variable directly inside callback's. So you have to pass using use params. function ($view)($userId){
But I don't think auth user will available in service provider's So
call inside View composer.
View::composer('client_panel.layouts.menu', function ($view) {
$view->with('newprojects', Project::where([
['status','=','1'],
['created_by','=',Auth::user()->id]
])->count());
});
To see if there's an n + 1 problem in my Laravel API, I want to see how many and which query statements were executed.
I use barryvdh/laravel-debugbar to see the query statements on web.php routes but this doesn't provide me the wanted info on api.php routes.
You can create a ServiceProvider that "listens" to all the queries being executed. You can print them on screen, write them to a log file, whatever you want.
Check https://laravel.com/docs/8.x/database#listening-for-query-events for the docs on Laravel 8.
Literal copy/paste example from the docs:
<?php
namespace App\Providers;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
DB::listen(function ($query) {
// Print it, log it, whatever :)
// $query->sql
// $query->bindings
// $query->time
});
}
}
Im working on a Laravel 5 app and im trying to set up a ComposerServiceProvider to pass data to a couple of views (im trying now to add it to the layout/app.blade.php).
I did this following the documentation but the data im trying to add is still undefined..
In my config/app.php I added to the providers:
App\Providers\ComposerServiceProvider::class,
On ComposerServiceProvider.php
boot method:
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
On the new created LayoutAppComposer.php
compose(View $view) method:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
But When i access the url I still get:
Undefined variable: metaTitle (View: .../resources/views/layouts/app.blade.php)
Am I missing something here??
ServiceProvider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\View;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
View::composer(['layouts.app'], 'App\ViewComposers\LayoutAppComposer');
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
}
}
LayoutAppComposer
<?php
namespace App\ViewComposers;
use Illuminate\Support\Facades\Session;
use Illuminate\View\View;
class LayoutAppComposer {
protected $metaTitle;
public function __construct($metaTitle)
{
$this->metaTitle = $metaTitle;
}
/**
* Bind data to the view.
*
* #param View $view
* #return void
*/
public function compose(View $view) {
$this->metaTitle = 'MetaTitle';
$view->with('metaTitle', $this->metaTitle);
}
}
Try changing:
$metaTitle = 'MetaTitle';
$view->with('metaTitle', $metaTitle)
to
$this->metaTitle = 'metaTitle';
$view->with('metaTitle', $this->metaTitle)
setup $this->metaTitle as a protected class member and assign it in the composer constructor. it may be that $metaTitle is getting garbage collected before you use it since this being resolved at the service provider level.
Since you're registering the composer with your app layout, instead you may need to use the wildcard character in place of app.layout like such:
View::composer('*', function ($view) {
//
});
To resolve $metaTile for the View Composer, try binding in your AppServiceProvider:
$this->app->bind('metaTitle', 'the string i want displayed across all views');
how do i get current logged in user details in laravel 5.2 ? I have done something to get the user name but it doesn't work properly.
Here is the code that gets the current logged-in user name
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use DB;
use Illuminate\Contracts\Auth\User;
use App\Http\Controllers\Controller;
use App\Http\Controllers\Auth\AuthController;
class UserProfileController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* #return \Illuminate\Http\Response
*/
public function current_user()
{
if(\Auth::check() && \Auth::user()->name) {
return 'hello';
return user()->name;
}
}
}
Here If i just return a ** return 'Hello'** in the function current_user , it works fine after checking the if condition, so i see there is no problem with if condition. But when i return user()->name it says
Call to undefined function App\Http\Controllers\user()
To access authorized user information use \Auth::user(). You probably just missing \Auth:: part, because You using correct syntax in condition.
You need to change your code a little bit.
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use DB;
use Illuminate\Contracts\Auth\User;
use App\Http\Controllers\Controller;
use App\Http\Controllers\Auth\AuthController;
class UserProfileController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Show the application dashboard.
*
* #return \Illuminate\Http\Response
*/
public function current_user()
{
if(\Auth::check() && \Auth::user()->name) {
return 'Hello '.\Auth::user()->name; //this line changed
}
}
}
After that you can get the current user name.
You want to return 2 values, that's not possible. When you return something your method will stop running. So that's why you didn't get the user name.
Hope this works!
When I'm trying to pass an object through a view with the AppServiceProvider it gives an error an says
Trying to get property of non-object
This is currently my App\Providers:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\User;
use Auth;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* #return void
*/
public function boot()
{
$users = Auth::user();
view()->share('user','users');
}
/**
* Register any application services.
*
* #return void
*/
public function register()
{
//
}
}
And when I say in the view:
{!! user->name !!}
It throws an error.
you are missing the '$' on users when passing the variable to view. So it can't be rendered on the view.
it must be:
$users = Auth::user();
view()->share('user', $users);
