【问题描述】：

我似乎无法用 django 脆皮表单覆盖默认标签。

模型.py

class User(AbstractUser):
    house_name_number = models.CharField(max_length=255)
    street_name = models.CharField(max_length=255)
    town_city = models.CharField(max_length=255)
    county = models.CharField(max_length=255)
    postcode = models.CharField(max_length=8)
    same_address = models.BooleanField()  
    move_in_date = models.DateField(null=True)

forms.py

class AddressForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.label_class = 'sr-only'
        self.helper.form_tag = False
        self.helper.layout = Layout(
            PrependedText('postcode', '<i class="fa fa-home"></i>', placeholder="Postcode", autofocus=""),
            PrependedText('house_name_number', '<i class="fa fa-home"></i>', placeholder="Building Number or Name",
                          ),
            PrependedText('street_name', '<i class="fa fa-home"></i>', placeholder="Street Name",
                          ),
            PrependedText('town_city', '<i class="fa fa-home"></i>', placeholder="Town or City",
                          label="test"),
            PrependedText('county', '<i class="fa fa-home"></i>', placeholder="County"),
            Field('same_address', '<i class="fa fa-home"></i>',
                  label="Have you lived at the property for 3 years"),
            PrependedText('move_in_date', '<i class="fa fa-calendar"></i>', required=False,
                          placeholder="What date did you move in to your current address"),
        )

【问题讨论】：

不知道为什么脆的表单覆盖不起作用。但我使用class Meta: 和标签选项docs.djangoproject.com/en/dev/topics/forms/modelforms/… 做了一个解决方法

标签： django django-crispy-forms

【解决方案1】：

我建议在表单的__init__ 方法中设置自定义标签：

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['town_city'].label = 'Test'
    ...

将label="something" 添加到 Crispy Forms 字段将导致输入字段上出现“标签”属性，这不是您想要的。

    labels = {
