You can now finally hate workflows

For a good long amount of time, workflows have been an essential part of Episerver Commerce (and even before that, Mediachase eCF). Once you get into order system, you just can’t escape workflows – because you need them. They handle many – if not all things, from validating items, checking inventories (to make sure that you are not selling something out-of-stock, or just discontinued (think of Galaxy Note 7, poor little shiny phone)), applying promotions, calculating taxes, process payments, and finally adjust inventories (yay, a customer places an order, let’s ship to him as soon as possible, firstly allocate the goods for him). And workflows are even required by later processing – when you complete the shipments (another happy customer!), or when you issue a return or an exchange (well, let’s keep the customer still happy).

EntryContentBase, MetaObject, CatalogEntryDto, Entry: which should you use?

It can be pretty confusing for new Commerce developers to understand how to work effectively with entries in Commerce. There are many things which represent the same concepts, however they are different and their APIs are not compatible. So which is which and what should you use?

Which is which

    • CatalogEntryDto is the DataSet to represent one or more entries (CatalogEntryDto can of course be empty). Beside the basic information like Name, Code, or MetaClassId, depends on how did you load it, a CatalogEntryDto can contain information about the assets, the associations or the variations (you can specify what to load by using CatalogEntryResponseGroup parameter. CatalogEntryDto, however, does not contain information of the metadata system of an entry – for example, if you add a metafield named “Description” to your entry metaclass – that is not available in a CatalogEntryDto.
      CatalogEntryDto can be loaded or saved by ICatalogSystem methods.

    Catalog Search APIs are for editing only!

    If you are using Catalog Search APIs for any customer-facing features, you are doing it wrong!

    I have seen this problem a couple of times – the search feature on the site is “dead” – it is very slow, and the log file is usually filled with dead lock or timeout error. As it turns out, the search feature was implemented by Catalog Search APIs, which is a big no-no.

    To be clear, there are two builtin APIs related to searching in Episerver Commerce: the “fast” one, which can be done via SearchManager, ISearchCriteria and ISearchResults, is the SearchProvider APIs. It’s the indexed search (strictly speaking, you can make it not “indexed”, but that’s beside the point), and the actual search functions will be provided by providers, like LuceneSearchProvider, Solr35SearchProvider, or FindSearchProvider.
