I am using laravel 5.4 i got and error that
FatalThrowableError in HasRelationships.php line 487: Class 'User' not
found
In my model i am using the following code
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Auth;
use App\User;
class Review extends Model
{
public function user()
{
return $this->belongsTo('User');
}
}
Could any one help me fix this error
You should use App\User in belongsTo. If you provide only User it will look for User in the base directory. But User is in the App namespace. :
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Auth;
use App\User;
class Review extends Model
{
public function user()
{
return $this->belongsTo('App\User');
}
}
Edit :
belongsTo require a namespace of a model you can achieve it either with above mentioned method or with User::class. As it will also return the namespace of User class.
return $this->belongsTo(User::class);

I am getting really confused on how namespace and use are being used here to reference my CategoryController. I am using laravel 8. Any guidance would be greatly appreciated!
My route uses resource and that seems to be ok.
web.php:
namespace App\Http\Controllers\Admin\Category;
Route::get('/admin/categories', [CategoryController::class, 'category'])->name('categories');
My Category Controller is App\Http\Controllers\Admin\Category\CategoryController.php as shown here is my folder structure:
CategoryController.php:
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class CategoryController extends Controller
{
public function __construct()
{
$this->middleware('auth:admin');
}
public function category(){
echo "Hello Category";
}
}
Your namespaces should mimic your directory structure. So if you have a CategoryController.php file that resides in the folder app/Http/Controllers/Admin/Category, then the namespace for that file would be namespace App\Http\Controllers\Admin\Category;
namespace App\Http\Controllers\Admin\Category;
use App\Http\Controllers\Controller;
class CategoryController extends Controller
{
// stuff
}
When referencing classes, you include the relevant namespace with the use statement.
So in your web.php file you want to replace:
namespace App\Http\Controllers\Admin\Category;
with:
use App\Http\Controllers\Admin\Category\CategoryController;
I added a method to one of my models:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Test extends Model
{
public static function boot()
{
parent::boot();
static::created(function ($model) {
//log $model or maybe do something more complex here
});
}
}
And i wish to extend the same behaviour to many other models. Copy pasting this doesent seem like a good idea because if something changes i dont want to change it in different places. What is the best solution to write this only once and get the same behaviour to multiple models?
Traits are built for that. Write once and use on all classes.
Create a trait in app/Traits/MyTraitName.php
<?php
namespace App\Traits;
use Carbon\Carbon;
trait MyTraitName
{
public function someName() {
// TO DO;
}
}
and then just import it on top of any model class for example User:
<?php
namespace App;
use App\Traits\MyTraitName;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable, MyTraitName;
..............
The difference between extending a class and making a trait is that when you make a trait that function is already written and it's automatically used the same way on every model, and extending from some base class is better if that function is not going to be the same for every Model.
I using Laravel, I have a Model class under App/Models
<?php
namespace App\Models;
class TodoList extends \Eloquent{
public function listItems(){
return $this->hasMany('TodoItem');
}
}
In my Controller I have included the namespace as follows:
namespace App\Http\Controllers;
...
use App\Models\TodoItem;
use App\Models\TodoList;
class TodoListController extends Controller
My method looks like this:
public function show($id)
{
$list=TodoList::findOrFail($id);
return \View::make('todos.show')->with('list', $todo_list);
}
but when I call to a request i get the error:
FatalErrorException in TodoListController.php line 75: Class
'App\Models\TodoList' not found
Trying running composer dump-autoload. Basically your classes become cached so you need to tell Laravel to look for newly added classes.
I'm not sure, just try this :
namespace App\Models;
use Illuminate\Database\Eloquent\Model as Eloquent;
class TodoList extends Eloquent{
public function listItems(){
return $this->hasMany('TodoItem');
}
}
Here is the code from the docs, but for your example. Note the use Model:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class TodoList extends Model {
//insert public function listItems() here
}
Hope this is helpful!
Make sure the file is in the correct folder and has the same name caption as the Class you want to import.
If the caption of the file "TodoList" is not TodoList.php but Todolist.php for example, Laravel wont find it.
Depending on your setup running "composer dump" might help to refresh autoload files.
I'm trying to get the hang of Laravel 5 and have a question which is probably very simple to solve but I'm struggling.
I have a controller named TestController and it resides in \app\Http\Controllers
This is the controller:
<?php
namespace App\Http\Controllers;
class TestController extends Controller {
public function test()
{
$diamonds = diamonds::find(1);
var_dump($diamonds);
}
}
Then I have a model I created that resides in /app:
<?php
namespace App;
class diamonds extends Model {
}
Put all other mistakes aside which I'm sure there are, my problem is that laravel throws an error:
FatalErrorException in TestController.php line 10: Class
'App\Http\Controllers\diamonds' not found
So, how do I get the controller to understand I'm pointing to a model and not to a controller?
Thanks in advance...
You have to import your model in the Controller by using namespaces.
E.g.
use App\Customer;
class DashboardController extends Controller {
public function index() {
$customers = Customer::all();
return view('my/customer/template')->with('customers', $customers);
}
}
In your case, you could use the model directly App\diamonds::find(1); or import it first with use App\diamonds; and use it like you already did.
Further, it is recommended to use UpperCamelCase class names. So Diamonds instead of diamonds. You also could use dd() (dump and die) instead of var_dump to see a nicely formatted dump of your variable.
//Your model file
<?php
namespace App\Models;
class diamonds extends Model {
}
// And in your controller
<?php
namespace App\Http\Controllers;
use App\Models\
class TestController extends Controller {
public function test()
{
$diamonds = diamonds::find(1);
var_dump($diamonds);
}
}
Try adding the following lines above your class decleration in your controller file...
use App\Diamonds;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
(this assumes your model file is called Diamonds.php)
Ultimately, there were a few issues here and all of you helped, however I was missing the following on the model page:
use Illuminate\Database\Eloquent\Model;
In my app I have Event and User models.Because of Event model I have to put it into namespace .so I created namespace as of following.
Event
<?php namespace App\Models;
class Event extends \Eloquent {
public function user()
{
return $this->belongsTo('User');
}
User
<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
use App\Models\Event;
class User extends Eloquent implements UserInterface, RemindableInterface {
public function events()
{
return $this->hasMany('Event');
}
The relations between User and Event are simple OneToMany. So in my EventController I use POST method to create new event resource .
$e = new Event(array('keys'=>'values')); //without user_id filled
$user->events()->save($e);
At the same time i got an error .
Call to undefined method Illuminate\Support\Facades\Event::newQuery()
If I am not wrong i guess it is namespace error.But namespaces are already declared correctly I guess.
But I try visiting similar questions and used alternative way in relationship and then it worked fine.Personally I don't find it satisfied.Any idea why this is occurred ?
Change the above relation to
public function events()
{
return $this->hasMany('\App\Models\Event');
}
If you put Event inside a namespace you need to use it with it's fully qualified classname.
You can either import it into your controller:
use App\Models\Event;
Or specify the namespace inline:
new App\Models\Event();
Also, I would recommend that if you create a namespace for models that you put all of them in there. (User is missing a namespace in your code)
