Laravel can't find class in namespace - php

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.

Target class [App\Http\Controllers\Admin\Category\CategoryController] does not exist

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;

Symfony\Component\Debug\Exception\FatalThrowableError Class '\App\Admin' not found

I am using laravel-5.7. i am making multi auth system I'm getting the following error
Symfony\Component\Debug\Exception\FatalThrowableError Class '\App\Admin' not found
Suppose you have Model class called Admin in the App folder, then you are calling it somewhere in the controller.
namespace App;
use Illuminate\Database\Eloquent\Model;
class Admin extends Model
{
//
}
Your controller will be
<?php
namespace App\Http\Controllers;
use App\Admin;
use Illuminate\Http\Request;
class YourController extends Controller
{
//Your code goes here
}
The answer is in the error that you get. You either don't have a class in your app directory named Admin or you don't have the namespace on top of your class.
<?php namespace App;
class Admin
{
}
or if your error is in a different class then you need to import it on top.
...
use PATH_TO_THE_ADMIN;
class YourClass {}
Most of the times when your class is not found, is basically as a result of not importing your namespace or typo error. so checke the two before anything else

Laravel: Model Class not found in relationships

Using Relationships first time and having issue to understand it.
I have a Student Class and a Course Model Class. A student can take many courses. In Student Model I do this:
public function course()
{
return $this->belongsTo('Course');
}
and in controller when I do this: .$student->course()->course_title it gives an error:
FatalThrowableError in Model.php line 779:
Class 'Course' not found
What am I doing wrong?
replace your code with it
public function course()
{
return $this->belongsTo(Course::class);
}
Make sure your namespace in your Course class matches 'App\Models'. You might be trying to access an "empty" namespace.
Namespaces are declared at the top of your class file. So for example:
Course.php:
namespace App\Models;
use Illuminate\Http\Request;
...
class Course extends Model { ... }
OtherClass.php
namespace App\Models;
use Illuminate\Http\Request;
...
class OtherClass extends Model {
...
public function course()
{
return $this->belongsTo('App\Models\Course')
}
}
Please note that the namespace declared at the top of Course.php matches the path provided to the relationship method (return) belongsTo(). You can also provide Course::class to the belongsTo method, but you need to import aka use the class in your php class.
I hope this helps!
I had the same problem and i solved it by adding a name space in the top of my model
for your case,
use \App\Course ; // Your name space of your class in relation
Hope this help others
NB : I used Laravel 5.0

Where to save new model file in laravel 5.3 and how to call model method from controller

Where to save new model file created in laravel 5.3 in /app/http folder or in /app folder
And how I will call the method in it from controller ?
How to include the model in controller?
Laravel 5.3
Save them in app/models folder and you can access it by constucting it,Make sure you have ran composer dump-autolad
public function __construct(YourModel $model) {
parent::__construct();
$this->model = $model;
}
in your code simply model->test();it should work.
You create the folder Modelswherever you want and add your files as you wish, just make sure to properly namespace it. As long as Composer can autoload the class.
You can manually create app/Models/User.php and just make sure to namespace it:
namespace App\Models;
class User {
// your code
}
And to call the model method from a controller use the namespace of the model:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\YourModel;
use App\Http\Requests;
use App\Http\Controllers\Controller;
class YourModelController extends Controller
{
public function whatever(){
$yourmodel->method();
}
}

How do I call a model in Laravel 5?

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;
