nopCommerce Ошибка: действия по уходу за детьми не разрешается выполнять переадресацию действия

Question

Я использую MVC nopCommerce и разработки пользовательских плагинов которые замещают существующие функциональные HomepageBestSellers (действие ProductController, который приписывается в качестве [ChildActionOnly]).

FilterProvider:

namespace Nop.Plugin.Product.BestSellers.Filters 
{ 
    public class BestSellersFilterProvider : IFilterProvider 
    { 
     private readonly IActionFilter _actionFilter; 

     public BestSellersFilterProvider(IActionFilter actionFilter) 
     { 
      _actionFilter = actionFilter; 
     } 

     public IEnumerable<Filter> GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor) 
     { 
      if (actionDescriptor.ControllerDescriptor.ControllerType == typeof(ProductController) && actionDescriptor.ActionName.Equals("HomepageBestSellers")) 
      { 
       return new Filter[] 
       { 
        new Filter(_actionFilter, FilterScope.Action, null) 
       }; 
      } 

      return new Filter[] { }; 
     } 
    } 
} 

Action Filter:

namespace Nop.Plugin.Product.BestSellers.Filters 
{ 
    public class BestSellersFilter : ActionFilterAttribute 
    { 
     private readonly ISettingService _settingService; 
     private readonly IStoreService _storeService; 
     private readonly IWorkContext _workContext; 

     public BestSellersFilter(ISettingService settingService, 
      IStoreService storeService, IWorkContext workContext) 
     { 
      this._settingService = settingService; 
      this._storeService = storeService; 
      this._workContext = workContext; 
     } 

     public override void OnActionExecuting(ActionExecutingContext filterContext) 
     { 
      //load settings for a chosen store scope and ensure that we have 2 (or more) stores 
      var storeScope = 0; 
      if (_storeService.GetAllStores().Count < 2) 
       storeScope = 0; 

      var storeId = _workContext.CurrentCustomer.GetAttribute<int>(SystemCustomerAttributeNames.AdminAreaStoreScopeConfiguration); 
      var store = _storeService.GetStoreById(storeId); 
      storeScope = store != null ? store.Id : 0; 

      var bestSellersSettings = _settingService.LoadSetting<BestSellersSettings>(storeScope); 

      if (bestSellersSettings.IsBestSellersEnabled) 
      { 
       filterContext.Result = new RedirectResult("Plugins/BestSellersProducts/PublicInfo"); 
      } 
      else 
       base.OnActionExecuting(filterContext); 
     } 
    } 
} 

Я получаю следующее сообщение об ошибке на filterContext.Result = новый RedirectResult ("Плагины/BestSellersProducts/PublicInfo"); эта линия:

Child actions are not allowed to perform redirect actions.

UPDATE:

1. Изменено BestSellersFilter.cs в соответствии с ответом.

   public override void OnActionExecuting(ActionExecutingContext filterContext) 
   { 
       var storeScope = 0; 
       if (_storeService.GetAllStores().Count < 2) 
        storeScope = 0; 
   
       var storeId = _workContext.CurrentCustomer.GetAttribute<int>(SystemCustomerAttributeNames.AdminAreaStoreScopeConfiguration); 
       var store = _storeService.GetStoreById(storeId); 
       storeScope = store != null ? store.Id : 0; 
   
       var featuredProductsSettings = _settingService.LoadSetting<FeaturedProductsSettings>(storeScope); 
   
       if (featuredProductsSettings.IsFeaturedProductsEnabled) 
       { 
        var products = _productService.GetAllProductsDisplayedOnHomePage(); 
   
        BestSellersController objResult = new BestSellersController(); 
        filterContext.Result = new ContentResult { Content = objResult.PublicInfoPlugin() }; 
        //base.OnActionExecuting(filterContext); 
       } 
       else 
        base.OnActionExecuting(filterContext); 
   } 
   

2. Изменено BestSellersController.cs в соответствии с ответом.

   public string PublicInfoPlugin() 
   { 
       var featuredProductsSettings = _settingService.LoadSetting<FeaturedProductsSettings>(_storeContext.CurrentStore.Id); 
       if (featuredProductsSettings.IsFeaturedProductsEnabled) 
       { 
       var products = _productService.GetAllProductsDisplayedOnHomePage(); 
       //ACL and store mapping 
       products = products.Where(p => _aclService.Authorize(p) && _storeMappingService.Authorize(p)).ToList(); 
       //availability dates 
       products = products.Where(p => p.IsAvailable()).ToList(); 
   
       if (products.Count == 0) 
        return ""; 
   
       var model = PrepareProductOverviewModels(products.Take(featuredProductsSettings.ShowFeaturedProductsNumber)).ToList(); 
       return RenderPartialViewToString("~/Plugins/Product.FeaturedProducts/Views/ProductFeaturedProducts/PublicInfo.cshtml", model); 
       } 
   
       return ""; 
   } 
   

Теперь получать Null значения из всех частных объектов в PublicInfoPlugin методом.

Answer 1

Вместо RedirectResult, установите его в ContentResult и установить Content свойство на выходе из действия вашего плагина:

filterContext.Result = new ContentResult { Content = "Load your plugin's action here" };
