Django api调用视图保存用户模型的外键

Question

我正在做的是django 2项目调用api到django 1项目在Appointment表中预约并将详细信息保存到BookAppt表中。

根据给出的答案之一更新我的代码后，我现在收到此错误。 {"patientId":["This field is required."]} 我不知道为什么，即使我已经包含了它。

请帮忙，因为我已经在这部分卡了 2 天了。

请注意，这是 django 2 调用 django 1。这是我的代码：

-model.py

-- django 1

class Appointments (models.Model):
    patientId = models.IntegerField()
    clinicId = models.CharField(max_length=10)
    date = models.DateField()
    time = models.TimeField()
    created = models.DateTimeField(auto_now_add=True)
    ticketNo = models.IntegerField()

    STATUS_CHOICES = (
        ("Booked", "Booked"),
        ("Done", "Done"),
        ("Cancelled", "Cancelled"),
    )
    status = models.CharField(max_length=20, choices=STATUS_CHOICES, default="Booked")

-- django 2

class MyUser(AbstractUser):
    userId = models.AutoField(primary_key=True)
    gender = models.CharField(max_length=6, blank=True, null=True)
    nric = models.CharField(max_length=9, blank=True, null=True)
    birthday = models.DateField(blank=True, null=True)
    birthTime = models.TimeField(blank=True, null=True)

class BookAppt(models.Model):
    clinicId = models.CharField(max_length=20)
    patientId = models.ForeignKey(MyUser, on_delete=models.CASCADE)
    scheduleTime = models.DateTimeField()
    ticketNo = models.CharField(max_length=5)
    status = models.CharField(max_length=20)

错误

Answer 1

我猜你在BookApptSerializer 中有问题。从patientId 字段中删除MyUserSerializer 并使用默认值。它将接受 id 字符串或数字。如果要显示用户数据，可以覆盖to_representation方法或者使用MethodField。

class BookApptSerializer(serializers.ModelSerializer):

    class Meta:
        model = BookAppt
        fields = ('id', 'patientId', 'clinicId', 'scheduleTime', 'ticketNo', 'status')
