11 - Laravel 5.8 Nova

Nova (opens new window) 是由 Laravel 官方團隊開發的後台管理面板 https://nick-basile.com/blog/post/getting-started-with-laravel-nova

這裡使用了andersao/l5-repository (opens new window), 但不是Nova的重點！

透過artisan生成l5-repository Model

php artisan make:entity News

全部選y 一共生成了

• app/Contracts/PostRepository.php
• app/Entities/Post.php
• app/Http/Controllers/API/PostsController.php
• app/Http/Controllers/WCMS/PostsController.php
• app/Http/Requests/PostCreateRequest.php
• app/Http/Requests/PostUpdateRequest.php
• app/Http/Resources/PostCollection.php
• app/Nova/Post.php
  • 主要是在這個file
• app/Presenters/PostPresenter.php
  • Laravel框架中如何使用 Presenter 模式? (opens new window)
• app/Providers/RepositoryServiceProvider.php
  • 在boot( )加了一行
• app/Repositories/PostRepositoryEloquent.php
• app/Validators/PostValidator.php
• database/migrations/2019_08_19_180303_create_posts_table.php

app/Nova/Post.php

public function fields(Request $request)
{
    return [
        ID::make()->sortable(),
        Text::make('Name', 'name')
            ->sortable()
            ->rules('required', 'max:255'),
        BelongsTo::make('Category', 'productCategory', 'App\Nova\ProductCategory'),
        //BelongsTo::make('Category', 'productCategory', ProductCategory::class),
        Image::make('image')->disk('public'),
        Boolean::make('Enabled'),
    ];
}

坑: 不能任何column名不可以有任何大寫!!! 會讀唔到，但又唔會出error... 例如image 唔可以 imagePath

未完...

Filter

app/Nova/Product

class ProductCategory extends Resource
{
    /**
     * The model the resource corresponds to.
     *
     * @var string
     */
    public static $model = 'App\Entities\Product';
    
    ...
    
    public function filters(Request $request)
    {
        return [
            new Filters\ProductCategoryType
        ];
    }
}

app/Nova/Filters/ProductCategoryType.php

class ProductCategoryType extends Filter
{
    public function apply(Request $request, $query, $value)
    {
        return $query->where('categories_id', $value);
    }
    
    public function options(Request $request)
    {
        //https://stackoverflow.com/a/52632103/5588637
        $categories = \App\Entities\ProductCategory::all();
        return $categories->pluck('id', 'name')->all();
    }
}
