由于 slug 和外键，django 表单未提交

Question

我的 django 小屋表单没有提交。我在我的小屋模型中应用了外键和 slug，之后我的表格停止提交。每当我输入所有字段并点击提交按钮时，表单页面都会重新加载并且没有数据提交。最重要的是它没有显示任何错误，以便我可以修复它。我已经尝试并搜索了很多关于它并尝试过不同的东西，但它仍然没有工作。我坚持下去。请帮忙！！

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)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.name)
        super(Centre, self).save(*args, **kwargs)


  class Cabin(models.Model):
     random_string = str(random.randint(100000, 999999))
     centre_name = models.ForeignKey(Centre, on_delete=models.CASCADE,blank=True,null=True)
     code = models.CharField(max_length=6, blank=False, unique=True, default=random_string)
     total_seats = models.IntegerField(blank='False')
     category=models.CharField(max_length=100, default=False)
     booked_date=models.DateField(blank='False')
     released_date=models.DateField(blank='False')
     price=models.IntegerField(blank=False, default=None)
     slug = models.SlugField(unique=False,default=None)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.category)
        super(Cabin, self).save(*args, **kwargs)


 In views.py file

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


    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.cabin = Cabin.objects.filter(slug=self.kwargs['slug'])[0]
        self.object.save()
        return HttpResponseRedirect(self.get_success_url())


   In my cabin template,

Answer 1

您的问题似乎出在您的 views.py 文件中。您正在告诉视图它应该构建一个包含模型上字段的__all__ 的表单，但在您的模板中您不包含slug 字段。由于您已经覆盖了Cabin 模型上的save 方法来填充slug 字段，我猜您不希望它显示在模板中。

您有两个选项可以解决此问题。您可以向包含 slug 字段的模板添加一个隐藏字段。或者，我认为更好的选择是，您可以更改视图上的 fields 属性以排除 slug 字段。

 class CabinCreateView(CreateView):
     fields = ('centre_name', 'code', 'total_seats', 'category', 'booked_date', 'released_date', 'price',)
     model = Cabin
     success_url = reverse_lazy("NewApp:logindex")

附：这不是您要问的问题，但我不禁注意到您的模板中有多个损坏的变量。您可能需要检查您的标签 for="" 属性是否按预期工作。
