After creating several Apps with Laravel and using softDelete properties I realized that methods like destroy(), restore() and kill() are exactly the same among several controllers. Therefore I am trying to put themn in a trait and use it from diferent Controllers.
My code is as follows:
ProfilesController.php
<?php
namespace App\Http\Controllers;
use App\Profile;
class ProfilesController extends Controller
{
public function destroy(Profile $profile)
{
Profile::del($profile, 'profiles');
return redirect()->route('profiles.index');
}
public function trashed()
{
Profile::trash('Profile');
}
}
Profile.php (model)
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Profile extends Model
{
protected $fillable = ['user_id', 'role_id', 'title', 'subtitle', 'slug', 'birthday', 'about'];
use SoftDeletes, Helpers, commonMethods;
public function getRouteKeyName()
{
return 'slug';
}
// ... more code here
}
trait file: commonMethods.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Auth;
use App\Profile;
use Session;
trait commonMethods
{
public static function del($element, $page_name)
{
$element->delete();
Session::flash('success', $element . ' successfully deleted!');
}
public static function trash($model)
{
$total = $model::onlyTrashed()->get();
$total_tr = count($total);
$all_tr = $model::all();
return view('partials.templates.trashed', compact('total', 'total_tr', 'all_tr'));
}
// ...more code here
}
The problem:
I try to visit the view "Trashed" that will list all elements "softdeleted" but not "killed", the method.
I pass the $model variable with the method trash($model)
I get the following error:
Class App/Profile does not found. Try to call App/Profile
I have debugged and the $model variable contains exactly what I need, the string 'Profile' which is what I need to build the Query:
$total = Profile::onlyTrashed()->get();
This query works while in the ProfilesController, but does not work while in a trait, since the model class is not found.
Any idea how could I make it work?
I am using Laravel 6.
If you need to use a class as a string you will want to use its full name. 'App\Profile' instead of 'Profile'.
$model = 'Profile';
new $model; // will use `\Profile`
$model = 'App\Profile';
new $model; // will use '\App\Profile';
In your controller( ProfilesController ) write :
use App\Profile;
In your model write :
use App\commonMethods;

I'm using Lumen 8.3 ,wanted to use factory() function in my tests, it gives me
Undefined Function ,there is nothing useful in the Docs of Lumen
Am i missing something here?
class ProductTest extends TestCase
{
public function test_if_can_send_products_list(){
$products = factory('App/Products',5)->make();
$this->json('post','/payouts',$products)
->seeJson([
'created' => true,
]);
}
}
->
Error: Call to undefined function factory()
It's better to use direct class like that:
$products = factory(Products::class, 5)->create();
don't forget to add Products model usage (namespace).
Edit
You should create Factory:
<?php
namespace Database\Factories;
use App\Products;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
class ProductFactory extends Factory
{
protected $model = Products::class;
public function definition(): array
{
return [
'name' => $this->faker->unique()->userName()
];
}
}
And add HasFactory Trait to your model:
use Illuminate\Database\Eloquent\Factories\HasFactory;
class Products extends Model {
use HasFactory;
}
you can also use it like this
Products::factory()->count(5)->make();
I just uncommented these lines in app.php file
$app->withFacades();
$app->withEloquent();
Apparently Laravel 8 removed the 'factory' helper, and it seems Lumen followed that path without updating documentation;
#Faesal Answer is the correct way to do it these days;
remember to add use HasFactory; to your Model.
I want to pass $defaultFrom from NewsletterController.php:
<?php
namespace App\Http\Controllers;
use App\Mail\NewsletterMail;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Mail;
class NewsletterController extends Controller
{
public function send()
{
$defaultFrom = 'newsletter#stuttard.de';
DB::table('newsletter_mails')->insert(['from' => $defaultFrom]);
$emails = DB::select('select * from newsletters order by id desc');
foreach ($emails as $email) {
Mail::to($email)->send(new NewsletterMail());
}
}
}
to NewsletterMail.php:
<?php
namespace App\Nova;
use Illuminate\Http\Request;
use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;
class NewsletterMail extends Resource
{
public function fields(Request $request)
{
return [
ID::make(__('ID'), 'id')->sortable(),
Text::make('From', 'from')->default($defaultFrom)->placeholder($defaultFrom),
];
}
}
I've tried to put public $defaultFrom; above the fields() function or call new NewsletterMail($defaultFrom) but this seems to be wrong syntax. Sorry, I'm a bit new to Laravel.
I assume that you have Newsletter model. Move $defaultFrom to model as public const DEFAULT_FROM = 'newsletter#stuttard.de';. After doing this, you can call it's value in both places using Newsletter::DEFAULT_FROM.
I want to use strtolower() before saving data in database for 5 attributes,
I'm using this code in Model
public function setFirstNameAttribute($value)
{
$this->attributes['firstName'] = strtolower($value);
}
public function setLastNameAttribute($value)
{
$this->attributes['lastName'] = strtolower($value);
}
public function setUserNameAttribute($value)
{
$this->attributes['userName'] = strtolower($value);
}
... etc
Can I use the __construct method instead of the above code?
There are two ways first one, to use boot method directly (preferred for small changes in model like in your question)
Method 1 :
we can directly use the boot method,
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Mymodel extends Model
{
public static function boot()
{
parent::boot();
static::saving(function ($model) {
// Remember that $model here is an instance of MyModel
$model->firstName = strtolower($model->firstName);
$model->lastName = strtolower($model->lastName);
$model->userName = strtolower($model->userName);
// ...... other attributes
});
}
}
Method 2 :
So we can use here a simple trait with a simple method for generating a strtolower() for a string.This is preferred when you have to do bigger changes in your model while performing operations in model like saving, creating etc. Or even if you want to use the same property in multiple models.
Create a trait MyStrtolower
<?php
namespace App\Traits;
trait MyStrtolower
{
public function mystrtolower($string)
{
return strtolower($string);
}
}
We can now attach this trait to any class that we want to have the mystrtolower method.
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use App\Traits\MyStrtolower;
class Mymodel extends Model
{
use MyStrtolower; // Attach the MyStrtolower trait to the model
public static function boot()
{
parent::boot();
static::saving(function ($model) {
// Remember that $model here is an instance of MyModel
$model->firstName = $model->mystrtolower($model->firstName);
$model->lastName = $model->mystrtolower($model->lastName);
$model->userName = $model->mystrtolower($model->userName);
// ...... other attributes
});
}
}
If you want to not repeat all these lines of code for every model you make, make the trait configurable using abstract methods so that you can dynamically pass the attribute names for which you want to lower case string, like employee_name is Employee Model and user_name in User Model.
I'm new to Laravel and the documentation's basic task list returns Views from the Route(web.php) but I want to use a Controller to return an image file.
So I have for my route:
Route::get('/products', 'ProductController#index');
Then my ProductController action (please ignore comments as I'm using index to simplify things):
<?php
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;
class ProductController extends Controller
{
/**
* Display a listing of the resource.
*
#return \Illuminate\Http\Response
Fetch and return all product records.
*/
public function index()
{
//
//return response()->json(Product::all(), 200);
return view('/pages/product', compact('product'));
}
And my product.blade.php (nested in views/pages/product):
<img src="/images/product/Frozen_Ophelia_800x.png">
I keep getting a ReflectionException Class App\Product does not exist.
I got this working when I just returned a view from the route. I'm getting a ReflectionException
Class App\Product does not exist so I think it's something at the top, ie. use App\Product; that is wrong.
Edit (below is my App\Product nested in app/Providers):
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Product extends Model
{
//
use SoftDeletes
protected $fillable = [
'name', 'price', 'units', 'description', 'image'
];
public function orders(){
return $this->hasMany(Order::class);
}
}
Assuming App\Product model exists, correct code should be:
public function index() {
$product = Product::all();
return view('pages.product', compact('product'));
}
Check the docs.
PS did you call a $ composer dumpautoload? ReflectionException Class error is often related to new class autoloading (eg. new classes in a packages)
view function should have any view template not any url or route. Of you have file views/pages/product.blade.php then use
view('pages.product',compact('product'));
I am pretty new to Laravel and I am trying to add the post, create by a user into the database. But when I do so, following error comes:
Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::save()
must be an
instance of Illuminate\Database\Eloquent\Model, string given,
called in C:\xampp\htdocs\lar\app\Http\Controllers\PostController.php on line
25 and defined
User model:
<?php
namespace App;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
class User extends Model implements Authenticatable
{
use \Illuminate\Auth\Authenticatable;
public function posts()
{
return $this->hasMany('App\Post');
}
}
Post Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
public function user()
{
return $this->belongsTo('App\User') ;
}
}
PostController:
<?php
namespace App\Http\Controllers;
use App\Post;
use Illuminate\Http\Request;
class postController extends Controller
{
public function postCreatePost(Request $request){
// Validation
$post = new Post();
$post->$request['body'];
$request->user()->posts()->save('$post');
return redirect()->route('dashboard');
}
}
Post Route:
Route::post('/createpost',[
'uses' => 'PostController#postCreatePost',
'as'=>'post.create'
]);
Form action:
<form action="{{route('post.create')}}" method="post">
Please tell me how to fix this.. How to fix this?
Thank you in advance.. :)
I think what you want is this:
<?php
namespace App\Http\Controllers;
use App\Post;
use Illuminate\Http\Request;
class postController extends Controller
{
public function postCreatePost(Request $request){
// Validation
$post = new Post();
// here you set the body of the post like that
$post->body = $request->body;
// here you pass the $post object not as string
$request->user()->posts()->save($post);
return redirect()->route('dashboard');
}
}
You need to pass the $post object as an object to the save method. You was doing this: $user->posts()->save('$post') when you need to do this: $user->posts()->save($post).
Hope it helps.
