Laravel Nova 404 when using hasMany

Question

In my Laravel Nova project, I have a Page and a PageTranslation (model and resource). When adding a hasMany to my Resource fields, upon visiting the detail of the Page, I get a 404 error. This is my code

This is my Page Resource

<?php

namespace App\Pages\Resources;

use Illuminate\Http\Request;
use Laravel\Nova\Resource;
use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Fields\HasMany;

class Page extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'App\Pages\Models\Page';

    /**
     * The single value that should be used to represent the resource when being displayed.
     *
     * @var string
     */
    public static $title = 'working_title';

    /**
     * @var string
     */
    public static $group = 'Pages';

    /**
     * The columns that should be searched.
     *
     * @var array
     */
    public static $search = [
        'id', 'working_title'
    ];

    /**
     * Eager load translations
     */
    public static $with = ['translations'];

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),

            Text::make('Title', 'working_title')
                ->sortable()
                ->rules('required', 'max:256'),

            HasMany::make('Translations', 'translations', \App\Pages\Resources\PageTranslation::class)

        ];
    }

}

This is my PageTranslation Resource

<?php

namespace Codedor\Pages\Resources;

use Illuminate\Http\Request;
use Laravel\Nova\Resource;
use Laravel\Nova\Fields\ID;
use Laravel\Nova\Fields\Text;

class PageTranslation extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'Codedor\Pages\Models\PageTranslation';

    /**
     * Hide resource from Nova's standard menu.
     * @var bool
     */
    public static $displayInNavigation = false;

    /**
     * Get the fields displayed by the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function fields(Request $request)
    {
        return [
            ID::make()->sortable(),

            Text::make('Locale')
                ->sortable()
                ->rules('required', 'max:256')
        ];
    }
}

I'm a little bit late, but if anyone comes across this issue while using Nova::resources instead of the resources path inside resources method in NovaServiceProvider, make sure you add the related resource to the list.

If you wish to hide a resource from the sidebar navirgation, just use public static $displayInNavigation = false; inside the resource file
