我與中間的一個實體有多對多的關係。帶關係對象條件的greenDao queryBuilder
這是我的模型聲明:
//### Family
Entity family = schema.addEntity("Family");
Property familyId = family.addIdProperty().getProperty();
family.addStringProperty("zid_family").notNull();
family.addStringProperty("zglosa");
family.addStringProperty("zidioma");
family.addIntProperty("zposicion");
family.addIntProperty("zestado");
//### Tax Family
Entity taxFamily = schema.addEntity("TaxFamily");
Property taxFamilyId = taxFamily.addIdProperty().getProperty();
taxFamily.addStringProperty("zid_family").notNull();
taxFamily.addStringProperty("zid_tax").notNull();
//### Tax
Entity tax = schema.addEntity("Tax");
Property taxId = tax.addIdProperty().getProperty();
tax.addStringProperty("zid_tax").notNull();
tax.addStringProperty("zglosa");
tax.addStringProperty("zpais");
tax.addIntProperty("ztype");
tax.addFloatProperty("zvalor");
//@@@ Relatinships
//family
ToMany familyToTaxFamily = family.addToMany(taxFamily, taxFamilyId);
familyToTaxFamily.setName("taxs_family");
familyToTaxFamily.orderAsc(taxFamilyId);
//tax
ToMany taxToTaxFamily = tax.addToMany(taxFamily, taxFamilyId);
taxToTaxFamily.setName("familys_tax");
taxToTaxFamily.orderAsc(taxFamilyId);
taxFamily.addToOne(family, familyId);
taxFamily.addToOne(tax, taxId);
問題是我找不到路和任何文檔實現這樣的事情:
List<Tax> result = taxDao.queryBuilder().where(taxDao.Properties.Ztype.eq(TAX_DETAIL_TYPE)).and(ImpuestoDao.ToMany("familys_tax").Zid_family.eq(ID_FAMILY)).list();
更新:
如果是不清楚: 我需要類似這樣的謂語
type == <TYPE_TAX> AND ANY familys_tax.id_family == <ID_FAMILY>
個
任何稅款familys_tax對象有id_family等於ID_FAMILY
非常感謝!
