Simplify to reduce problems. If an app does not need stores, it can create only one store an set it as default.

What's the point of recording Product(and Detail)ModificationTime in order line?
@gdlcf88 Thanks advance 😄

• Change SerializedDto to SerializedEntityData.
• Move ProductHistoryRecorder and ProductDetailHistoryRecorder to the domain layer.

• Change ProductDetail to an aggregate root.
• A Product must have one ProductDetail.
• A ProductSku may have one ProductDetail.
• A ProductDetail can be updated when the user has permission to manage the related Product.
• Usually, ProductDetail belongs to only one Product or ProductSku.
• Product and ProductDto will not contain the product's details, the only way to get them is using ProductDetail's API.

In the future, we create a new git repository named EasyMall to provide an ABP application solution with installer or an ABP startup template.

• Remove IMultiTenant from Product and other related entities.
• Add ProductStore for mapping products to stores in different tenants.

CRUD for ProductSku

• Remove the requirement of Get/GetList permissions from Product and Category.
• Remove the requirement of Get permissions from ProductDetail.
• GetList with ShowHidden == true requires .Default permission.

• A new setting named "CurrencyCode" in the Orders module.
• It specifies a valid currency code for stores, tenants, and the host.
• It will finally fall back to "USD" if the value doesn't set.
• Check whether the currency code of OrderLines is equal to the value from the setting.
• The store-side setting value implementation depends on #174.

Its route should be "/api/eShop/orders/order/byOrderNumber/{orderNumber}".

Use IStoreOwnerStore to check whether the user is one of the store owners, if so, he has the authority.

For example:

should be:

var isStoreOwner = await _storeOwnerStore.IsOwnerAsync(CurrentUser.GetId(), input.StoreId)
    && await AuthorizationService.IsGrantedAsync(ProductsPermissions.Products.Default);

• Sharing tables with PaymentService module. Should make sure they are in the same app.
• Payment and Refund in Payments module have extra StoreId property.
• Add management pages for the new entities.
• Set StoreId property for Payment entity in EShopOrderPaymentAuthorizer.

Use IProductAppService.GetAsync() to get the inventory.

• Add OrderNumber property to Order entity.
  • It must be set before the entity inserted.
  • It has a unique index.
• Create IOrderNumberGenerator interface to create new order numbers.
• Add GetByOrderNumberAsync() method to IOrderAppService.

• Create IProductDiscountManager and IProductDiscountProvider.
• Add MinimumPrice, MaximumPrice, DiscountedPrice and RealInventory properties to ProductDto and set their values in IProductAppService.GetAsync and IProductAppService.GetListAsync methods.

代码里面一行注释都看不到。很多字段完全靠翻译的中文字面意思猜。

If it is null, skip the default value setting in WeChatPaySettingDefinitionProvider.

Should add "EShop" prefix, for example:

public const string RemoteServiceName = "Orders";

should be

public const string RemoteServiceName = "EShopOrders";

For example:
ConfigureOrders() -> ConfigureEShopOrders()

When it set to true, hide it from the product/category list.

ProductsPermissions.Products.Default

According to https://github.com/EasyAbp/EasyAbpGuide/blob/master/Module-Development-Specification.md#menu-items

EShopProductsProductCategory should be used as the menu item name instead of Category.

• The default value of OrderMaxQuantity is 99.
• Make sure the order line's Quantity is between OrderMinQuantity and OrderMaxQuantity.

After EasyAbp/PaymentService#6 finished, EShop.Payments module does not need to be deployed with PaymentService module, so the Payment and Refund should be exclusive table entities which automatically synchronize entity data from PaymentService module.

Add IsStatic property to Product entity, if it set to true, no one can modify them except those with the ManageStaticProduct permissions

And add StoreId to the parameters of CreateAsync(), UpdateAsync() and DeleteAsync().

• Create/Delete a ProductAttribute: should ensure all SKUs are removed.
• Delete a ProductAttributeOption: should ensure related SKUs are removed.
