如何重命名ForeignKey的设置字段在Django的REST框架

Question

我采用序列化Django的REST框架外键设置，我有以下型号：

class Transaction(models.Model): 
    ... 
class TransactionStatus(models.Model): 
    transaction = models.ForeignKey(Transaction) 
    ... 

我有这两种模式的串行器，其中一个长相像这样：

class TransactionSerializer(serializers.ModelSerializer): 
    transactionstatus_set = TransactionStatusSerializer(many=True, read_only=True) 

    class Meta: 
     model = Transaction 
     depth = 1 
     fields = ('id', 'transactionstatus_set') 

我想在这里有交易的列表，从引用_set查询集回状态......但transaction_set只是似乎很别扭的名字在API为..

快速运行实验我发现，这将这样的伎俩后：

class TransactionSerializer(serializers.ModelSerializer): 
    changes = TransactionStatusSerializer(many=True, read_only=True, source='transactionstatus_set') 

    class Meta: 
     model = Transaction 
     depth = 1 
     fields = ('id', 'changes') 

现在我有一个好听的名字外键链接的状态列表...
