Retrieve Products using Commerce Server Foundation

ravikanth | November 10, 2009

Commerce serer 2007 exposes different API for different purpose but the main disadvantage is that it doesn’t give flexibility to develop ecommerce applications for multiple devices (channels – mobiles, kiosk, etc). To overcome this problem Microsoft has wrapped a new API model (multi-channel foundation) on top on existing commerce server runtime API. It exposes a set of models, known as commerce entities (such as products and baskets – similar to .NET entities) to represent the conceptual view of e-commerce. To know more about this, you can refer to following urls.

http://microsoftblog.co.in/commerceserver/how-i-learnt-commerce-server-foundation/

http://msdn.microsoft.com/en-us/library/dd327929.aspx

In this post, I am trying to fetch products under a category using commerce server foundation. The method takes three parameters – catalog name, category name and user id and returns all products in the form of datatable.

public  DataTable GetChildProducts(string CatalogName, string parentCategory, string userId)
{
CommerceRequestContext requestContext = new CommerceRequestContext();
requestContext.Channel = "Default";
requestContext.UserId = userId;
requestContext.RequestId = Guid.NewGuid().ToString();
requestContext.UserLocale = "en-US";
requestContext.UserUILocale = "en-US";

// Create a Operation Service Agent
OperationServiceAgent operationService = new OperationServiceAgent();

// Define DataTable
DataTabl productsDataTable =new DataTable();

// Query for a Product
CommerceQuery<CommerceEntity> queryBuilder = new CommerceQuery<CommerceEntity>("Category");
queryBuilder.SearchCriteria.Model.Id = parentCategory;
queryBuilder.Model.Properties.Add("Id");
queryBuilder.Model.Properties.Add("DisplayName");
queryBuilder.Model.Properties.Add("ListPrice");
queryBuilder.Model.Properties.Add("Description");

// Add more properties here….
queryBuilder.SearchCriteria.Model.Properties["CatalogId"] = CatalogName;

// Add Related Query Operation for Canonical Categories
{
CommerceQueryRelatedItem<CommerceEntity> childProduct = new CommerceQueryRelatedItem<CommerceEntity>("ChildProducts", "Product");
childProduct.Model.Properties.Add("Id");
childProduct.Model.Properties.Add("DisplayName");
childProduct.Model.Properties.Add("ListPrice");
childProduct.Model.Properties.Add("Description");
queryBuilder.RelatedOperations.Add(childProduct);
}

CommerceResponse response = operationService.ProcessRequest(requestContext , queryBuilder.ToRequest());

// Handle Responses
CommerceQueryOperationResponse queryBuilderResponse = (CommerceQueryOperationResponse)response.OperationResponses[0];
productsDataTable.Rows.Clear();
if (queryBuilderResponse.CommerceEntities.Count > 0)
{
CommerceEntity category = queryBuilderResponse.CommerceEntities[0];
//Iterate over Child products
if (category.GetPropertyValue("ChildProducts") != null)
{
foreach (CommerceRelationship childProduct in (CommerceRelationshipList)category.GetPropertyValue("ChildProducts"))
{      
            CommerceEntity product = childProduct.Target;
             DataRow newProductRow = productsDataTable.NewRow();
             newProductRow["id"] = product.Id;
             newProductRow["DisplayName"] = product.GetPropertyValue("DisplayName");
             newProductRow["Description"] = product.GetPropertyValue("Description");
             newProductRow["Price"] = product.GetPropertyValue("ListPrice");
             productsDataTable.Rows.Add(newProductRow);
}
}
}
return productsDataTable;
}

Steps involved in extended commerce server 2009 Systems

ravikanth | August 27, 2009

In this post, I am trying to explain what are the steps involved in extending commerce server 2009 sub-systems. The process for extension is the same as CS2007 but some additional steps are added.

1.    Adding Fields in LineItem Table ( Database )
2.    Create Extended Line Item Class
3.    Configure the assembly information in Web config.
4.    Configure the Fields information in Order Mapping.
5.    Configure the Fields information in Order Pipeline.
6.    Execute Ordermapping.exe tool and execute output sql statements in transaction database.
7.    Create new Extended Translator Class to translate entities to CS2007 objects or vise versa.
8.    Configure the assembly  information in Channel Configuration.
9.    Configure the Property Mapping in Mapping Configuration.
10.    Modifying XSLT of the web part so that the updated field is shown.

Note: Green means existing process Blue means new process.

In next posts, I will be going in details explaining the steps involved creating custom translator (in detail).
