Question

我有模特：

class Order(models.Model):

    user = models.ForeignKey('accounts.User', blank=True, null=True)
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)

class Reservation(models.Model):

    start = models.DateTimeField(db_index=True)
    end = models.DateTimeField(db_index=True)
    order = models.ForeignKey(Order, related_name='reservations')

和序列化器：

class ReservationSerializer（serializers.HyperlinkedModelSerializer）：

order_first_name = serializers.CharField(read_only=True)
order_last_name = serializers.CharField(read_only=True)
order_id = serializers.IntegerField(read_only=True)

class Meta:
    model = Reservation
    fields = ('id',
              'start',
              'end',
              'order',
              'order_first_name',
              'order_last_name',
              'order_id',

              )
    read_only_fields = ('order', 'order_first_name', 'order_last_name', 'order_id')

问题是我在API响应中看不到order_first_name和order_last_name，也没有错误。

Answer 1

好的，这可行

order_first_name = serializers.ReadOnlyField（source =＆＃39; order.first_name＆＃39;，read_only = True）
