TypeError : 'manuscript' is an invalid keyword argument for this function

Question

在我的健康应用程序中，我试图让用户输入患者症状数据并保存。

我的应用包含 Identity、Symptom 和 IdentitySymptom 模型。

Identity 和 Symptom 之间存在 ManyToManyField。

IdentitySymptom 模型包含两个 ForeignKey 字段，每个字段都引用 Identity 和 Symptom 模型。

在我的视图文档中，我使用了基于 class 的视图来确保我创建的每个症状对象都与患者相关联。

问题：每次我创建一个症状对象并单击保存它时，它 returns 这个错误：

我已经从我的 Identity 模型创建了患者对象。

class Identity(models.Model):

    NIS =models.CharField(max_length = 200, primary_key = True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL)
    time_patient_creation = models.DateTimeField(auto_now = True)
    first_name = models.CharField(max_length = 80, null = True)
    last_name = models.CharField(max_length = 80, null = True )
    contact = models.CharField(max_length = 15, null = True)
    location  = models.CharField(max_length = 100, blank = True)
    born = models.DateField(auto_now = False, auto_now_add = False, blank = True, null = True)

    patient_key = models.ManyToManyField('Symptom')

我还从 Symptom 模型

创建了 Symptom 对象

我还创建了一个包含 ForeignKey 字段的 IdentitySymptom 模型

class IdentitySymptom(models.Model):

    identity = models.ForeignKey(Identity)
    key_medical = models.ForeignKey(Symptom)

这是我的观点文档，基于 class 的观点

Answer 1

这一行

medical_key = IdentitySymptom.objects.create(patient = patient, manuscript = manuscript)

引发错误，因为 IdentitySymptom 没有稿件字段。

根据您的定义，

class IdentitySymptom(models.Model):

    identity = models.ForeignKey(Identity)
    key_medical = models.ForeignKey(Symptom)

您只能分配 identity 和 key_medical。

我可以看到 patient 是一个 Identity 实例，假设手稿是 Symptom，那么你实际上想做

medical_key = IdentitySymptom.objects.create(identity = patient, key_medical = manuscript)
