У меня есть такая база данных: у меня вопрос «Как отобразить эту базу данных с помощью активной записи замка?»
альтернативный текст http://cA4.upanh.com/11.396.15558077.LNS0/onetoonewithcompositekey.jpg Я пробовал этот код: Campaign:
[ActiveRecord("[Campaign]")]
public class Campaign : ActiveRecordBase<Campaign>
{
private long m_ID;
[PrimaryKey(Column = "`ID`")]
public long ID
{
get { return m_ID; }
set { m_ID = value; }
}
//// Properties ...
private IList<MessageOfCampaign> m_MessageOfCampaign = new List<MessageOfCampaign>();
[HasMany(typeof(MessageOfCampaign),
Table = "`MessageOfCampaign`",
ColumnKey = "`CampaignID`")]
public IList<MessageOfCampaign> MessagesOfCampaign
{
get { return m_MessageOfCampaign; }
set { m_MessageOfCampaign = value; }
}
}
MessageOfCampaign:
[Serializable]
public class MessageOfCampaignKey
{
private long m_MessageID;
[KeyProperty(Column = "`MessageID`")]
public long MessageID
{
get { return m_MessageID; }
set { m_MessageID = value; }
}
private long m_CampaignID;
[KeyProperty(Column = "`CampaignID`")]
public long CampaignID
{
get { return m_CampaignID; }
set { m_CampaignID = value; }
}
public override bool Equals(object obj)
{
if (this == obj)
{
return true;
}
MessageOfCampaignKey key = obj as MessageOfCampaignKey;
if (key == null)
{
return false;
}
if (m_CampaignID != key.m_CampaignID || !m_MessageID.Equals(key.m_MessageID))
{
return false;
}
return true;
}
public override int GetHashCode()
{
return this.m_CampaignID.GetHashCode() ^ this.m_MessageID.GetHashCode();
}
}
[ActiveRecord("[MessageOfCampaign]")]
public class MessageOfCampaign : ActiveRecordBase<MessageOfCampaign>
{
private MessageOfCampaignKey m_Key;
[CompositeKey]
public MessageOfCampaignKey Key
{
get { return m_Key; }
set { m_Key = value; }
}
private Message m_Message;
[OneToOne]
public Message Message
{
get { return m_Message; }
set { m_Message = value; }
}
private Campaign m_Campaign;
[BelongsTo("`CampaignID`")]
public Campaign Campaign
{
get { return m_Campaign; }
set { m_Campaign = value; }
}
}
Сообщение:
[ActiveRecord("[Message]")]
public class Message : ActiveRecordBase
{
private long m_ID;
[PrimaryKey(Column = "`ID`")]
public long ID
{
get { return m_ID; }
set { m_ID = value; }
}
//// Properties ...
[OneToOne]
public MessageOfCampaign MessageOfCampaign
{
get { return this.m_MessageOfCampaign; }
set { this.m_MessageOfCampaign = value; }
}
}
Но я получил ошибку:
отображение поврежденного столбца для: MessageOfCampaign.id of: IMobileMarketing.Models.Message, компонент типа [MessageID, CampaignID] ожидает 2 столбца, но 1 сопоставлен
