it helps some times You're probably running a Laravel 5.2 app. If so, you have two options:
1) Upgrade from Laravel 5.2 to Laravel 5.3, then try again, it will most definitely work. The Laravel upgrade takes about about 1 hour for a medium-sized project, but you'll have all the benefits of using the latest and greatest (both Laravel and Backpack).

Backpack for laravel - Guzzle instance error

will help you You can't overwrite the setUp method and add an argument, because the parent class doesn't take an argument in that method. You can however do it in the constructor:
class ImportacionesCrudController extends CrudController
    private $api;

    public function __construct(webApi $api) {
        $this->api = $api;
        return parent::__construct();

    public function setUp()

BACKPACK Laravel manage extra columns in pivot table in a many-to-many relationship using Backpack CRUD

fixed the issue. Will look into that further I've been able to solve it, so I'll post the solution as it may be useful for others.
What I did,
// add this to the use statements 
use App\Models\Task;
// Notice: You need to add this to "create" function as well, I'm just writing here the update function to keep it short.
 public function update(UpdateRequest $request)
$redirect_location = parent::updateCrud($request);
foreach ($request->machines as $machine) {
            $set= array('m'=>'0','t'=> '0', 's' => '0', 'a' => '0');
            if (isset($request['m'])) in_array ($machine, $request['m']) ? $set['m'] = '1' :  $set['m'] = '0';
            if (isset($request['t'])) in_array ($machine, $request['t']) ? $set['q'] = '1' :  $set['q'] = '0';
            if (isset($request['s'])) in_array ($machine, $request['s']) ? $set['b'] = '1' :  $set['b'] = '0';
            if (isset($request['a'])) in_array ($machine, $request['a']) ? $set['y'] = '1' :  $set['y'] = '0';

            Task::find($request->id)->machines()->syncWithoutDetaching([$machine => $set]);
return $redirect_location;

// Code explanation:
// what we are doing basically here is to grab the $request data
// For example: In the $request we receive m[3] b[1,3] y[1] arrays
// meaning that for our task:
// Machine 1 has no monthly, no quarterly but biannual and yearly checkboxes checked
// Machine 3 has monthly, no quarterly, biannual and no yearly checkboxes checked
// with the loop above, we cast that incoming data into this structure
// $set would contain after the loop:
// '1' => ['m' => '0', 'q'=> '0', 'b' => '1', 'y' => '1']
// '3' => ['m' => '1', 'q'=> '0', 'b' => '1', 'y' => '0']

// with that, we updated the intermediate table using syncWithoutDetaching

<div @include('crud::inc.field_wrapper_attributes') >
   <label>{!! $field['label'] !!}</label>
       name="{{ $field['name'] }}[]"
       style="width: 100%"
       id="select2_ajax_multiple_custom_{{ $field['name'] }}"
       @include('crud::inc.field_attributes', ['default_class' =>  'form-control'])

       @if ($old_value)
           @foreach ($old_value as $item)
               @if (!is_object($item))
                       $item = $connected_entity->find($item);
               <option value="{{ $item->getKey() }}" selected>
                   {{ $item->{$field['attribute']} }}
// What I added is:
   <div id="freq">
   @if ($old_value)
           @foreach ($old_value as $item)
               @if (!is_object($item))

               <div id="div{{ $item->getKey() }}">
               <span>{{ $item->{$field['attribute']} }} -- </span>
               Monthly <input type="checkbox" id="m{{ $item->getKey() }}" name="m[]" value="{{ $item->getKey() }}" @php if ($item->pivot['m'] == "1") echo "checked"; @endphp > 
               Quarterly <input type="checkbox" id="q{{ $item->getKey() }}" name="q[]" value="{{ $item->getKey() }}" @php if ($item->pivot['q'] == "1") echo "checked"; @endphp> 
               Biannual <input type="checkbox" id="b{{ $item->getKey() }}" name="b[]" value="{{ $item->getKey() }}" @php if ($item->pivot['b'] == "1") echo "checked"; @endphp> 
               Yearly <input type="checkbox" id="y{{ $item->getKey() }}" name="y[]"value="{{ $item->getKey() }}" @php if ($item->pivot['y'] == "1") echo "checked"; @endphp> <br/>


// js code to add or remove rows containing the checkboxes (This needs to be put inside <script> tags obviously)    $("#select2_ajax_multiple_custom_machines").on("select2:select", function(e) {
// add checkbox row
           htmlRow = "<div id=\"div"+e.params.data.id+"\">"+"<span> "+e.params.data.text+"-- </span>"+" Monthly <input type=\"checkbox\" id=\"m"+e.params.data.id+"\" name=\"m[]\" value=\""+e.params.data.id+"\">";
           htmlRow += " Quarterly <input type=\"checkbox\" id=\"q"+e.params.data.id+"\" name=\"q[]\" value=\""+e.params.data.id+"\">";
           htmlRow += " Biannual <input type=\"checkbox\" id=\"b"+e.params.data.id+"\" name=\"b[]\" value=\""+e.params.data.id+"\">";
           htmlRow += " Yearly <input type=\"checkbox\" id=\"y"+e.params.data.id+"\" name=\"y[]\" value=\""+e.params.data.id+"\"><br/>";
           htmlRow += "</div>";

$("#select2_ajax_multiple_custom_machines").on("select2:unselect", function(e) {
// remove checkbox row

Error on installing backpack for laravel 6.0.3

Tag : laravel , By : Hibame
Date : October 02 2020, 05:00 PM
This might help you There was indeed a problem with installing backpack/generators - composer did not fall back to an appropriate version, but it is now fixed. You should be able to run php artisan backpack:base:install without problems.
If you hit any roadblocks during the installation, I recommend you follow the manual installation procedure, instead of php artisan backpack:base:install.
