Android Ormlite:具有id的外键

我正在我的android项目中使用ormlite。我正在设法让外键工作。 这就是我现在所拥有的

我得到以下结构的json，需要将其保存到数据库中。为此，我创建了以下对象类

我上的第一堂课是：

@DatabaseTable(tableName = "gallery")
public class Gallery extends DatabaseModel {
public static final String FIELD_ID = "gal_id";
public static final String FIELD_TITLE = "gal_title";
public static final String FIELD_IMAGES = "gal_images";

//ID
@DatabaseField(columnName = FIELD_ID, id = true)
@SerializedName(FIELD_ID)
private int id;
//FIELDS
@DatabaseField(columnName = FIELD_TITLE)
@SerializedName(FIELD_TITLE)
private String title;
@ForeignCollectionField()
@SerializedName(FIELD_IMAGES)
private ForeignCollection<GalleryImage> images;

public Gallery() {

}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getTitle() {
    return title;
}

public void setTitle(String published) {
    this.title = title;
}

public ForeignCollection<GalleryImage> getImages() {
    return images;
}

public void setImages(ForeignCollection<GalleryImage> images) {
    this.images = images;
}

@Override
public void SaveAll(DataRepository repo, List<? extends DatabaseModel> models) {
    repo.galleryRepository.deleteAll();
    repo.galleryRepository.saveAll(repo, models);
}

@Override
public void Save(DataRepository repo) {
    repo.galleryRepository.create(this);
}
}

正如您所看到的，ForeingCollection有不止一个GalleryImage。在GalleryImage类中，我有一个名为“pho_gal_Id”的Id，它链接回“gal_Id”字段

这是我运行这两个类时得到的异常：
