List data from two unrelated tables in the same view

Question

I have a view called form where I need it to appear, in the select field, the States(UF) coming from Mysql. I have the EstadoController where in the index method I do the listing using all. Now, I want this listing to appear in the form view whose route is: Route::get('/formulario', 'FormularioController@create');

To EstadoController is like this:

public function index(Estado $estado){       
    $retornoAllEstado = $estado->all();
    return view('painel-adm.formulario', compact('retornoAllEstado'));
}

But when I foreach in the view form, I come across error:

<select class="custom-select" name="qpae_uf_rg">              
    @foreach($retornoAllEstado as $estado)
        <option value="1">{{$estado->uf}}</option>
    @endforeach          
</select>   

Error generated: Undefined variable: retornoAllEstado...

Formulariocontroller.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

/* Usando a model Formulario */
use App\Models\Painel\Formulario;

class FormularioController extends Controller
{
    private $formulario;


    public function __construct(Formulario $formulario)
    {

        $this->formulario = $formulario;
    }

    public function index()
    {

    }


    public function create()
    {
        return view('painel-adm.formulario');
    }  

    public function store(Request $request)
    {       


    }

    public function show($id)
    {

    }

    public function edit($id)
    {

    }

    public function update(Request $request, $id)
    {

    }

    public function destroy($id)
    {

    }
}

formulario.blade.php

<div class="form-group col-md-1">
        <label>UF</label>

        <select class="custom-select" name="uf">              
            @foreach($retornoAllEstado as $estado)
                <option value="1">{{$estado->uf}}</option>
            @endforeach          
        </select>           

    </div>

Answer 1

puts a dd(&returns) likely that you see it empty, that’s because your all() is running on the $status variable. which is not normal on the index

suggestion:

$retornoAllEstado = Estado::all(); 

Answer 2

Change the method create():

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Estado;
/**
* 
* code..
*/
public function create()
{
    $retornoAllEstado = new Estado::all();
    return view('painel-adm.formulario', compact('retornoAllEstado'));
} 
/**
* 
* code..
*/

remember to call the model at the beginning of your class use App/Estado;

Test and see if it works as you need it.
