這是我的模型：class Picture(models.Model):    picture_id = models.IntegerField(db_column='PictureID', primary_key=True)    gold_item =models.ForeignKey(GoldItem,db_column="GoldItemID",related_name="pictures",on_delete=models.CASCADE)    gold_item_branch = models.ForeignKey(GoldItemBranch, db_column="GoldItemBranchID", related_name="pictures", on_delete=models.CASCADE)    code = models.CharField(db_column='Code', max_length=5, blank=True, null=True)class GoldItemBranch(models.Model):    gold_item_branch_id = models.IntegerField(db_column='GoldItemBranchID', primary_key=True)    gold_item_id = models.IntegerField(db_column='GoldItemID')    gold_item_branch_name = models.CharField(db_column='GoldItemBranchName', max_length=30, blank=True, null=True)我需要對(duì)上述模型中的多個(gè)列執(zhí)行連接操作。列是 gold_item_id 和 gold_item_branch_id我寫了 SQL 查詢：select * from Pictures join GoldItemBranches on Pictures.GoldItemID = GoldItemBranches.GoldItemID and Pictures.GoldItemBranchID = GoldItemBranches.GoldItemBranchID我如何在 Django queryset 中執(zhí)行相同的查詢？
