Hi, Off topic (kind of), but wondering if someone could help please?
I'm trying to have a category based main menu (top nav), along with a drop down menu for each category, showing the sub categories. I managed to do this in 2.8, but for some reason using this multi-store version it's always retuning '0' sub categories?
CatalogController.cs[ChildActionOnly]
public ActionResult CategoryMenuNavigation(int currentMenuCategoryId, int currentMenuProductId)
{
//get active category
var activeCategory = _categoryService.GetCategoryById(currentMenuCategoryId);
if (activeCategory == null && currentMenuProductId > 0)
{
var productCategories = _categoryService.GetProductCategoriesByProductId(currentMenuProductId);
if (productCategories.Count > 0)
activeCategory = productCategories[0].Category;
}
var activeCategoryId = activeCategory != null ? activeCategory.Id : 0;
var customerRolesIds = _workContext.CurrentCustomer.CustomerRoles
.Where(cr => cr.Active).Select(cr => cr.Id).ToList();
string cacheKey = string.Format(ModelCacheEventConsumer.CATEGORY_MENU_NAVIGATION_MODEL_KEY, _workContext.WorkingLanguage.Id,
string.Join(",", customerRolesIds), _storeContext.CurrentStore.Id, activeCategoryId);
var cachedModel = _cacheManager.Get(cacheKey, () =>
{
var breadCrumb = activeCategory != null ?
GetCategoryBreadCrumb(activeCategory).Select(x => x.Id).ToList()
: new List<int>();
return new CategoryMenuNavigationModel()
{
Categories = PrepareCategoryMenuNavigationModel(0, breadCrumb).ToList()
};
}
);
//"CurrentCategoryId" property of "CategoryMenuNavigationModel" object depends on the current category or product.
//We need to clone the cached model (the updated one should not be cached)
var model = (CategoryMenuNavigationModel)cachedModel.Clone();
model.CurrentMenuCategoryId = activeCategoryId;
return PartialView(model);
}

[NonAction]
protected IList<CategoryMenuNavigationModel.CategoryModel> PrepareCategoryMenuNavigationModel(int rootCategoryId,
IList<int> breadCrumbIds)
{
var result = new List<CategoryMenuNavigationModel.CategoryModel>();
foreach (var category in _categoryService.GetAllCategoriesByParentCategoryId(rootCategoryId))
{
var categoryModel = new CategoryMenuNavigationModel.CategoryModel()
{
Id = category.Id,
Name = category.GetLocalized(x => x.Name),
SeName = category.GetSeName()
};
//product number for each category
if (_catalogSettings.ShowCategoryProductNumber)
{
var categoryIds = new List<int>();
categoryIds.Add(category.Id);
//include subcategories
if (_catalogSettings.ShowCategoryProductNumberIncludingSubcategories)
categoryIds.AddRange(GetChildCategoryIds(category.Id));
categoryModel.NumberOfProducts = _productService
.SearchProducts(categoryIds: categoryIds,
storeId: _storeContext.CurrentStore.Id,
pageSize: 1)
.TotalCount;
}
//subcategories
for (int i = 0; i <= breadCrumbIds.Count - 1; i++)
if (breadCrumbIds[i] == category.Id)
categoryModel.SubCategories.AddRange(PrepareCategoryMenuNavigationModel(category.Id, breadCrumbIds));
result.Add(categoryModel);
}
return result;
