Why soft deleted entities appear in query results? - laravel

Question

I am trying to implement soft deleting concept.
Here is my object:
class Post extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'posts';
protected $softDelete = true;
...
Soft delete is on.
Now, if I 'delete' a post, it gets a 'deleted_at' timestamp:
The problem is, when I search or just use all() to display the posts, the soft deleted items appears there. What is wrong?

Answer 1

Sometimes, you will get the soft deleted table entries with get() even with eloquent and protected $softDelete = true;.
So to avoid this problem, use
...->whereNull('deleted_at')->get();
For example, this query will fetch all rows including soft deleted.
DB::table('pages')->select('id','title', 'slug')
->where('is_navigation','=','yes')
->where('parent_id','=',$parent_id)
->orderBy('page_order')
->get();
So the proper method is,
DB::table('pages')->select('id','title', 'slug')
->where('is_navigation','=','yes')
->where('parent_id','=',$parent_id)
->whereNull('deleted_at')
->orderBy('page_order')
->get();

The soft deleting feature works when using Eloquent. If you are querying the results with query builder you will eventually see all the records trashed and not trashed.
It is not clear in the current docs of Laravel 4, but seeing that the concept of soft deleting just appears under Eloquent ORM - Soft Deleting and not under Query Builder, we can only assume that: soft delete only works with Eloquent ORM.

There is a little trick using soft delete tables and queries in laravel:
When we create something like
$objCars = Car::where("color","blue");
The system executes something like that:
SELECT
*
FROM
cars
WHERE
deleted_at IS NULL
AND
"color" = 'blue'
So far, so good. But, when we apply the "orWhere" method, something funny happens
$objCars = Car::where("color","blue")->orWhere("color","red");
The system will execute something like that:
SELECT
*
FROM
cars
WHERE
deleted_at IS NULL
AND
"color" = 'blue'
OR
"color" = 'red'
This new query will return all the car where deleted_at is null and the color is blue OR if the color is red, even if the deleted_at is not null. It is the same behavior of this other query, what show the problem more explicitly:
SELECT
*
FROM
cars
WHERE
(
deleted_at IS NULL
AND
"color" = 'blue'
)
OR
"color" = 'red'
To escape from this problem, you should change the "where" method passing a Closure. Like that:
$objCars = Car::where(
function ( $query ) {
$query->where("color","blue");
$query->orWhere("color","red");
}
);
Then, the system will execute something like that:
SELECT
*
FROM
cars
WHERE
deleted_at IS NULL
AND
(
"color" = 'blue'
OR
"color" = 'red'
)
This last query, searches for all cars where deleted_at is null and where the color can be or red or blue, as we was want it to do.

I had the same problem and nothing here helped me.
My problem was in my construct, I forgot to call the parent constructor:
public function __construct()
{
parent::__construct();
//Rest of my code
}
Hope that help someone!

Laravel 5.2.44 added withoutTrashed() method to SoftDeletingScope. For example you can use something like this:
Post::withoutTrashed()->get();

Answer 6

Tested it in Laravel 5.6, You need to use SoftDeletes Trait in your model
use Illuminate\Database\Eloquent\SoftDeletes;
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Banners extends Model
{
use SoftDeletes;
//no need of this below line
//protected $softDelete = true;
}
and when you query
$banners = Banners::where('status', 1)->get();
it will not return soft deleted data.

me solved join table with eloquent on softdelete - laravel 8
$query = Model_table_1::join('user', 'user.id', '=', 'table_1.user_id')
->join('table_2', 'table_2.id', '=', 'table_1.table2_id')
->join('table_3', 'table_3.id', '=', 'table_1.table3_id')
->join('table_4', 'table_4.id', '=', 'table_3.table4_id')
->select('table_1.id','table_1.name','table_1.created_at',
'user.name','table_2.name2','table_3.name3','table_4.name4')
->get();
use where in datables
$query = Model_table_1::join('user', 'user.id', '=', 'table_1.user_id')
->join('table_2', 'table_2.id', '=', 'table_1.table2_id')
->join('table_3', 'table_3.id', '=', 'table_1.table3_id')
->join('table_4', 'table_4.id', '=', 'table_3.table4_id')
->select('table_1.id','table_1.name','table_1.created_at','user.name','table_2.name2','table_3.name3','table_4.name4')
->where('table_1.user_id', '=', Auth::user()->id)
->get();
use where in view
$query = Model_table_1::join('user', 'user.id', '=', 'table_1.user_id')
->join('table_2', 'table_2.id', '=', 'table_1.table2_id')
->join('table_3', 'table_3.id', '=', 'table_1.table3_id')
->join('table_4', 'table_4.id', '=', 'table_3.table4_id')
->select('table_1.id','table_1.name','table_1.created_at','user.name','table_2.name2','table_3.name3','table_4.name4')
->where('table_1.user_id', '=', Auth::user()->id)
->first();
