Update

TIP

Don't forget that ArgoStore supports Upsert.

Following example shows how to get document by id, change it, and update it in DB.

csharp

// store is instance of IArgoDocumentStore
IArgoDocumentSession session = store.OpenSession();
Person? person = session.GetById<Person>(id);

if (person != null)
{
    person.CookiesCount--;

    session.Update(person);
    session.SaveChanges();
}

Calling Update will set document to be updated. Document id must be set. SaveChanges will execute all pending operations in a transaction. In this case the only pending operation is Update.

TIP

Unlike Entity Framework Core, ArgoStore does not track changed objects. You have to explicitly call Update with modified object.
