Problems with routes in laravel

I'm working with group routes on laravel 5.2 and I'm having problem with the create.store part of the route that saves my object.

My files are structured as follows:

ClientController.php

<?php

namespace App\Http\Controllers;

use Request;
use App\Http\Requests\CategoriaRequest;
use App\Categoria;

class CategoriaController extends Controller
{
public function index(){
    $categorias =  Categoria::all();

    if(Request::wantsJson()){
        return $categorias;
    }else{
        return view('Categoria.listCategoria', compact('categorias'));
    }
}

public function create(){
    $categoria = new Categoria();
    return view('Categoria.cadCategoria', compact('categoria'));
}

public function store(CategoriaRequest $resquest){
    dd($resquest);
    $categoria = Categoria::create($resquest->all());

    if(Request::wantsJson()){
        return $categoria;
    }else{
        return view('Categoria.listCategoria', compact('categoria'));
    }
}

public function show(Categoria $categoria){
    if(Request::wantsJson()){
        return $categoria;
    }else{
        return view('Categoria.showCategoria', compact('categoria'));
    }
}

public function edit(Categoria $categoria){
    return view('Categoria.editCategoria', compact('categoria'));
}

public function update(CategoriaRequest $request, Categoria $categoria){
    $categoria->update($request->all());
    if(Request::wantsJson()){
        return $categoria;
    }else{
        return view('Categoria.listCategoria');
    }
}

public function destroy(Categoria $categoria){
    $deleted = $categoria->delete();

    if(Request::wantsJson()){
        return (string) $deleted;
    }else{
        return view('Categoria.listCategoria');
    }
}
}

CategoryRequest.php

class CategoriaRequest extends Request
{
/**
 * Determine if the user is authorized to make this request.
 *
 * @return bool
 */
public function authorize()
{
    return true;
}

/**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'NmCategoria' => 'required|min:5',
        'DscCategoria' => 'required|min:5'
    ];
}
}

My model Categoria

class Categoria extends Model
{
protected $fillable = ['NmCategoria', 'DscCategoria'];

}

And my route looks like this:

Route::group(['middleware' => ['web']], function (){
  Route::resource('categorias', 'CategoriaController');
});

  

My first problem is when I am clicking on edit, my query is id, my field is CdCategory, thus giving error in the query:

     

    

SQLSTATE [42S22]: Column not found: 1054 Unknown column 'id' in 'where clause' (SQL: select * from categorias where id = 1 limit 1)   

What could it be?
