Question

在Django中，模型字段的命名约定是什么？我的问题是出现错误

django.core.exceptions.ImproperlyConfigured: Field name `tutor1` is not valid for model `ClientEntry`

在字段名称中使用整数是错误的吗？我可以用什么名字来命名它，例如tutor1，tutor2，tutor3？我也尝试了tutor_1，但遇到了同样的错误。

注意：tutor1 postgres ArrayField

编辑：这是回溯

django.core.exceptions.ImproperlyConfigured: Field name `amount_paid_tutor1` is not valid for model `ClientEntry`.

这是相关字段

amount_paid_to_tutor1 = ArrayField(
  models.IntegerField(
    blank=True
  ),
  blank=True,
  null=True
)

Serializer基本上是所有字段和视图，

class ClientEntryViewSet(viewsets.ModelViewSet):
  queryset = ClientEntry.objects.all()
  serializer_class = ClientEntrySerializer

Answer 1

似乎您的模型上有amount_paid_to_tutor1字段，但是由于amount_paid_tutor1而发生了错误。找到amount_paid_tutor1，然后更改为amount_paid_to_tutor1。
