Serializable carts

In the SerializedCarts data model, all cart data is stored in one table, SerializableCart. This table contains these defined and searchable columns:

• CartId
• Created
• Modified
• Name
• CustomerId
• MarketId (Customized Commerce 11.0 and higher)
• Data

The Data column is where all the cart data is serialized to JSON format and stored as a string.

Serializable components

All cart data is serialized to a JSON formatted string before persisting it to the database. To achieve this, several cart components participate in the serialization/deserialization, which takes IMarket as a parameter.

Add custom data

Serializable components implement the IExtendedProperties interface, and custom values can be added to the Properties collection on the Serializable components as long as the value can be JSON serialized.

Converting a serialized cart with custom properties to a purchase order requires the Meta Fields corresponding to the custom properties to be present on the purchase order type. See Extend order classes.

The mapping between the serialized cart's custom properties and the purchase order's corresponding meta fields is strictly based on property name. The serialized cart is created with an empty Properties on, meaning it is not prepopulated with the keys or default values of the meta fields added to the purchase order or the legacy cart metaclass.

Enable SerializedCarts

By default, the SerializedCarts mode is enabled for a new installation site.

You can use ApplicationOptions to enable/disable SerializedCarts feature:

{
       "ApplicationOptions":{
          "Features":{
             "SerializedCarts":{
                "Feature":"SerializedCarts",
                "State":1, // 0 is enabled, 1 for disabled
                "Type":"Mediachase.Commerce.Core.Features.SerializedCarts, Mediachase.Commerce"
             }
          }
       }
    }

Alternatively, enable the SerializedCarts mode programmatically by adding the following to your InitializeModule class:

ServiceLocator.Current.GetInstance<IFeatureSwitch>().EnableFeature(SerializedCarts.FeatureSerializedCarts);

Migrate existing legacy carts

If switching from a legacy version to Serializable carts, you may need to migrate existing carts. If so, run the scheduled job LegacyCartsMigrationJob available in the CMS admin view immediately after switching to the new cart system to complete the migration and remove legacy carts.

Commerce 14+ only:

• Delete any rows relating to LegacyCartsMigrationJob in tblscheduleditem and tblPlugin tables.
• Install package https://nuget.optimizely.com/package/?id=EPiServer.Commerce.Migration.Legacy
• Run the job.

📘

Note

You should run the scheduled job immediately after switching to serializable carts. After migrating legacy carts, the job is no longer visible in CMS admin view.
