提交表单时，django字段必填

Question

我正在尝试提交我的机舱表单，但是即使所有字段都已填写，它也一次又一次在机舱代码中显示“此字段为必填字段。请帮助我，我被卡住了。我在机舱型号代码中使用了外键，它似乎引起问题吗？你能告诉我我做错了什么吗？提前致谢。

In models.py

class Centre(models.Model):
     name= models.CharField(max_length=50, blank=False, unique=True)
     address = models.CharField(max_length =250)
     phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$',
                             message="Phone number must be entered in the format: '+999999999'. Up to 10 digits allowed.")
     contact = models.CharField(max_length=100, blank=False)
     phone = models.CharField(validators=[phone_regex], max_length=10, blank=True)  # validators should be a list
     slug = models.SlugField(unique=False)


class Cabin(models.Model):
    random_string = str(random.randint(100000, 999999))
    centre_name = models.ForeignKey(Centre, on_delete=models.CASCADE )
    code = models.CharField(max_length=6, blank=False, unique=True,                 default=random_string)
      total_seats = models.IntegerField(blank='False')


 views.py

class CabinCreateView(CreateView):
      fields = '__all__'
      model = Cabin
      success_url = reverse_lazy("NewApp:logindex")

“此字段为必填项”

Answer 1

该字段是导致此错误的原因：     空白=真 在 或为其添加定义一些默认值。
