Laravel Eloquent - Model::all() method give all result including soft deletes - php

Question

When I select all records using eloquent Model::all() method it's give me soft delete record too.
Model class
protected $table = 'tr_fl_tax_charges';
protected $primaryKey = 'fl_tax_id';
use SoftDeletes;
protected $softDelete = true;
protected $dates = ['deleted_at'];
Controller class
Case 1
public function index()
{
$tax = Tax::all();
return $tax;
}
it's give me all record including soft deleted row.
Case 2
public function index()
{
$tax = Tax::all()->where('deleted_at' , '=', null);
return $tax;
}
this case give me correct output and not including soft deleted rows but it's give me all the columns and I don't need all columns.I need only 4 columns.
Case 3
If I add column name that need in all() method it's give me soft deleted row too.
public function index()
{
$tax = Tax::all('fl_tax_id','fl_tax_type','fl_tax_name','fl_charge_type','fl_charge_rate')->where('deleted_at' , '=', null);
return $tax;
}
Case 4
If I add one more column deleted_At in case 3 it's give me expected output.
public function index()
{
$tax = Tax::all('fl_tax_id','fl_tax_type','fl_tax_name','fl_charge_type','fl_charge_rate', 'deleted_at')->where('deleted_at' , '=', null);
return $tax;
}
What I want is I want only those record which is not soft deleted and from those records I want to select columns. How ?
UPDATE WITH MODEL AND CONTROLLER FILES
Tax.php (Model) - here BaseModel extends Model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\SoftDeletes;
class Tax extends BaseModel
{
protected $table = 'tr_fl_tax_charges';
protected $primaryKey = 'fl_tax_id';
use SoftDeletes;
protected $softDelete = true;
//protected $fillable = ['fl_tax_type' , 'fl_tax_name' , 'fl_charge_type' , 'fl_charge_rate'];
protected $guarded = [];
protected $dates = ['deleted_at'];
}
TaxController.php
<?php
namespace App\Http\Controllers;
use App\Models\Tax;
use Illuminate\Http\Request;
use Validator;
class TaxController extends Controller
{
public function index()
{
$tax = Tax::all();
return $tax;
}

Answer 1

You need to remove the protected $softDelete = true; only leave the use SoftDeletes; will be OK.

Answer 2

With the current information provided, there is no reason that Case 1 should fail. Soft deletes work with the all() method, and I don't see any other issues in the currently provided code that would change that. I will update this answer if more code is provided that reveals the issue.
Case 2 "works" because you're actually calling where() on the Collection of all your Tax records. Tax::all() queries the database and builds a Collection of all the results, and then you're using where() to filter out the results with a null deleted_at field. This is highly inefficient.
Case 3 fails because your select list doesn't contain the deleted_at field. So, when you call where() on the Collection to only see the records where delete_at is null, all records will match since deleted_at doesn't exist. This is still calling where() on the Collection, not adding a where clause to the query, so it is inefficient.
Case 4 "works" again because you added the deleted_at field back in, so it will be in the Collection results, and the filtering can filter out the records where deleted_at is not null. But again, this is filtering the Collection of all your Tax records PHP side, not adding a where condition to your SQL query.

Answer 3

You should try this:
Change your Tax model and try:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\SoftDeletes;
class Tax extends BaseModel
{
use SoftDeletes;
protected $dates = ['deleted_at'];
protected $table = 'tr_fl_tax_charges';
protected $guarded = ['fl_tax_id','_token'];
}
