DBFlow使用JSONModel抛出InvalidDBconfiguration: JSONModel未向数据库注册

Question

我开始使用DBFlow并跟踪文档。我有一个巨大的JSON，我不想上传所有的内存，所以我使用他们已经实现的JSONModel方法。

    admissionJSONModel = new JSONModel<Admission>(jsonObject, Admission.class);

收生班：

@Table(databaseName = AppDatabase.NAME)
@ContainerAdapter
public class Admission extends BaseModel {

  /**
   * Ticket Reference (barcode number)
   */
  @NonNull
  @ContainerKey("TICKET_REF")
  @Column(columnType = Column.PRIMARY_KEY)
  String mTicketReference;

  @NonNull
  @Column
  @ContainerKey("FIRST_NAME")
  String mFirstName;

  /**
   * Ticket type (related to Record type)
   * In ADDRESS_CITY
   */
  @Column
  @ContainerKey("TICKET_TYPE")
  int mTicketType;


                ...
}

Ant数据库类：

@Database(name = AppDatabase.NAME, version = AppDatabase.VERSION, foreignKeysSupported = true)
public class AppDatabase {

    public static final String NAME = "App";

    public static final int VERSION = 1;
}

我拥有的异常的堆栈跟踪是：

(提前谢谢你:)

Answer 1

对于作者，如果使用的是ProcessModelTransaction，则应该更改代码以将JSONModel保存到DB中，如下所示：

TransactionManager.getInstance().addTransaction(new ProcessModelTransaction<>(ProcessModelInfo.withModels(models).table(Admission.class);

目前，这是一个不存在table()方法的错误。因此，它认为JSONModels是一个表(因为它们实现了模型)，但它只是实际模型的外壳、蓝图类。

谢谢你找到这个。如果您可以在github上打开一个问题，我可以将您标记为贡献者。谢谢。

Answer 2

现在，从1.6.1版本开始，它将检测到模型是ModelContainer，并将获取要使用的适当表。
