ORMLite与收集崩溃

Question

我有ormlite在android中坚持我的数据。 我有这个错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.firext.android/com.firext.android.activities.reportList.ReportListActivity}: java.lang.RuntimeException: java.sql.SQLException: Foreign collection class com.firext.android.model.bbdd.DBQuestionsGroup for field 'questionsGroup' column-name does not contain a foreign field named 'questionsGroupsList' of class com.firext.android.model.bbdd.DBQuestions 

我的课其本;

@DatabaseTable 
    public class DBQuestionsGroup { 

     @DatabaseField(generatedId = true, columnName = "_id") 
     private Long ID; 
     @DatabaseField(columnName = "times") 
     private int times; 
     @DatabaseField(columnName = "idQuestionsGroup") 
     private int idQuestionsGroup; 
     @DatabaseField(columnName = "nameQuestionsGroup") 
     private String nameQuestionsGroup; 
     @ForeignCollectionField 
     private Collection<DBQuestion> questionsGroupsList; 

getters and setter 


@DatabaseTable 
public class DBQuestion { 

    @DatabaseField(generatedId = true, columnName = "_id") 
    private int ID; 
    @DatabaseField(columnName = "question") 
    private String question; 
    @DatabaseField(columnName = "questionOrder") 
    private int questionOrder; 
    @DatabaseField(foreign = true,foreignAutoCreate = true) 
    private DBReplieType replyType; 
    @DatabaseField(columnName = "idQuestion") 
    private int idQuestion; 
    @DatabaseField(foreign = true, foreignAutoRefresh= true) 
    private DBQuestionsGroup DBQuestion; 

什么问题？

也许你需要在DBQuestionsGroup类ForeingCollection设置了这种方式：

@ForeignCollectionField 
private ForeignCollection<DBQuestion> questionsGroupsList;
