RavenDB OnBeforeStore不使用BulkInsert触发

Question

我不能让OnBeforeStore使用BulkInsert触发。

在正常的商店操作过程中，它会很好地触发。

我正在尝试使用发票号码生成器来添加一个格式化的数字，我想在OnBeforeStore中这样做。

参见代码示例：

static async Task GenerateInvoiceTest()
{
    using var store = new DocumentStore
    {
        Urls = new string[] { "https://localhost:8080" },
        Database = "APC",
    };

    //this never fires using BulkInsert
    store.OnBeforeStore += (s, e) =>
    {
        if (!(e.Entity is Invoice invoice)) return;
        if (invoice.InvoiceNumber != 0) return;
        invoice.InvoiceNumber = new Random().Next(1, 1000);
    };

    store.Initialize();

    //sample invoices
    var invoices = new List<Invoice>
    {
        new Invoice { StartDate = DateTime.Now, EndDate = DateTime.Now.AddDays(3) },
        new Invoice { StartDate = DateTime.Now, EndDate = DateTime.Now.AddDays(3) },
    };

    //bulk insert test
    using var session = store.OpenAsyncSession();
    using var bulkInsert = store.BulkInsert();
    invoices.ForEach(i => bulkInsert.Store(i));            
    
    //this does NOT fire OnBeforeStore
    await session.SaveChangesAsync();
    
    foreach (var invoice in invoices)
    {
        //always prints 0
        Console.WriteLine(invoice.InvoiceNumber);
    }

    //regular test
    var otherInvoice = new Invoice { StartDate = DateTime.Now, EndDate = DateTime.Now.AddDays(3) };

    await session.StoreAsync(otherInvoice);

    //this DOES fire OnBeforeStore
    await session.SaveChangesAsync();
}

OnBeforeStore作为会话 SaveChanges方法的一部分被调用。

请参阅有关OnBeforeStore的文档。

http://localhost:54391/docs/article-page/5.0/Csharp/client-api/session/how-to/subscribe-to-events

该事件采用参数BeforeStoreEventArgs，该参数由会话实体的ID和实体本身组成。

您可以在'Store‘上定义，但它不适合与bulkInsert一起使用。

它用于从会话中保存数据。

BulkInsert操作于商店本身，而不是会话
