Voyager - laravel admin panel

My question is related to controller in Voyager admin panel. For example I created a table with migration . It's name was "groups" and then I created BREAD and added it to menu in Voyager.

I created a folder that it's name is "groups" in \resources\views\vendor\voyager andthen I created two file to override the view.

But I do not know where the controller is . I created controller with php artisan make:controller GroupsController. I guess this controller is not related to voyager controllers.

I want to change the index or create method and pass some data to views in controller but I do not know where it is.

I created a controller in \vendor\tcg\voyager\src\Http\Controllers that it's name is VoyagerGroupsController.php but when I create class and index method in it , it does not work.

How can I create controller for "groups" and pass the data to the view?

Because it's now it's using your App controller not a Voyager controller so you have to override your full controller

like

In config/voyager.php add

'controllers' => [
'namespace' => 'App\\Http\\Controllers',
],

Create new controller like MyBreadController.php into App/controller

<?php

namespace App\Http\Controllers;
class MyBreadController extends \TCG\Voyager\Http\Controllers\Controller
{
//code here
}

app/Providers/AppServiceProvider.php

use TCG\Voyager\Http\Controllers\VoyagerBreadController;
use App\Http\Controllers\MyBreadController;
public function register()
{
$this->app->bind(VoyagerBreadController::class, MyBreadController::class);
//
}

I added Route::get('groups', 'GroupsController@index') as you said in routes/web.php

like this

Route::group(['prefix' => 'admin'], function () { Voyager::routes();

Route::get('groups', 'GroupsController@index');

});

and added these lines in index method

public function index(Request $request){

    // GET THE SLUG, ex. 'posts', 'pages', etc.
    $slug = $this->getSlug($request);

    // GET THE DataType based on the slug
    $dataType = DataType::where('slug', '=', $slug)->first();

    // Check permission
    Voyager::can('browse_'.$dataType->name);

    // Next Get the actual content from the MODEL that corresponds to the slug DataType
    $dataTypeContent = (strlen($dataType->model_name) != 0)
        ? app($dataType->model_name)->latest()->get()
        : DB::table($dataType->name)->get(); // If Model doest exist, get data from table name

    $view = 'voyager::bread.browse';

    if (view()->exists("voyager::$slug.browse")) {
        $view = "voyager::$slug.browse";
    }

    return view($view, compact('dataType', 'dataTypeContent'));

}

But getSlug method does not work. This error will be shown ErrorException in GroupsController.php line 23: Trying to get property of non-object

I guess after overriding Controlles getSlug() does not work and I have to set the slug manually $slug = 'groups';

Whenever we create a table in voyager, Voyager calls it datatype. And for all tables / datatypes created by us, Voyager users only one controller VoyagerBreadController.php located at **vendor\tcg\voyager\src\Http\Controllers**.

For example, if I create a table named brands. Laravel will use controller VoyagerBreadController.

But where are the routes which use or point to this controller. Routes are located in file vendor\tcg\voyager\routes\voyager.php. In this file, find the following lines:

try {
            foreach (\TCG\Voyager\Models\DataType::all() as $dataTypes) {
                Route::resource($dataTypes->slug, $namespacePrefix.'VoyagerBreadController');
            }
        } catch (\InvalidArgumentException $e) {
            throw new \InvalidArgumentException("Custom routes hasn't been configured because: ".$e->getMessage(), 1);
        } catch (\Exception $e) {
            // do nothing, might just be because table not yet migrated.
        }

In my version, these lines are between line No. 29 to 37.

As you can see, above code is fetching all our datatypes and creating a resouce route for our tables / datatypes.

Now, if I want to override this route and create a route to use my own controller for a particular action. For example, if I want to create a route for brands/create url. I can do this by simply adding following line (my route) below above code (i.e. after line 37):

Route::get('brands/create', function(){return 'abc';})->name('brands.create');

or you can do the same by adding following line in routes\web.php after Voyager::routes();

Route::get('brands/create', function(){return 'abc';})->name(**'voyager.brands.create'**);
