Django外键选择

我想构建一个应用程序，在这个应用程序中，患者将报告上传给他的同伴医生， 所以，我有两个模型，一个是给医生的，另一个是给病人的。 我想在这两种模式之间建立一种关系，即患者从注册医生中选择医生

代码如下：

class DoctorModel(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
    doctorName = models.CharField(max_length = 150 , default="")
    doctorEmail = models.EmailField(max_length=50, default="")
    speciality  = models.CharField(choices = SPECIALITY ,max_length = 20 , default="")
    doctorStatus  = models.CharField(choices = DOCTOR_STATUS ,max_length = 15 , default="")


class PatientModel(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
    patientName = models.CharField(max_length = 150 , default="", editable=True)
    patientAge = models.IntegerField(default=0)
    patientEmail = models.EmailField(max_length=50, default="", editable=True)
    insuranceSyndicate  = models.CharField(choices = INSURANCE_SYNDICATE, max_length = 15, default="")
    slug = models.SlugField(max_length = 50 , default= '')
    referencedDoctor = models.ForeignKey(DoctorModel, on_delete=models.Set_Null)

我想要的是，当患者选择“参考医生”时，他从DoctorModel中的“doctorName”中选择他

我该怎么做呢？

您应该为您的模型创建_; str _;方法

class DoctorModel(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
    doctorName = models.CharField(max_length = 150 , default="")
    doctorEmail = models.EmailField(max_length=50, default="")
    speciality  = models.CharField(choices = SPECIALITY ,max_length = 20 , default="")
    doctorStatus  = models.CharField(choices = DOCTOR_STATUS ,max_length = 15 , default="")

    def __str__(self):
        return f"{self.doctorName}"

顺便说一句，尝试对字段使用null=True。将更容易实现。

您可以在医生模型中定义dunder字符串函数，如下所示

class DoctorModel(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
    doctorName = models.CharField(max_length = 150 , default="")
    doctorEmail = models.EmailField(max_length=50, default="")
    speciality  = models.CharField(choices = SPECIALITY ,max_length = 20 , default="")
    doctorStatus  = models.CharField(choices = DOCTOR_STATUS ,max_length = 15 , default="")



    def__str__(self):
        return self.doctorName
