如何重命名ForeignKey的設置字段在Django的REST框架

Question

我採用序列化Django的REST框架外鍵設置，我有以下型號：

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

我有這兩種模式的串行器，其中一個長相像這樣：

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

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

我想在這裏有交易的列表，從引用_set查詢集回狀態......但transaction_set只是似乎很彆扭的名字在API爲..

快速運行實驗我發現，這將這樣的伎倆後：

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

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

現在我有一個好聽的名字外鍵鏈接的狀態列表...
