Question

我正在使用松脆的表格使表格看起来不错，并添加了以下验证：

forms.py

class Meta:
    widgets = {
            'dob': DatePickerInput(
                options={
                    "format": "MM/DD/YYYY",
                    "showClose": False,
                    "showClear": False,
                    "showTodayButton": False,
                }
            ),
    }

def clean(self):
        data = self.cleaned_data
        born = data.get('dob')
        today = date.today()
        age = (today.year - born.year - ((today.month, today.day) < (born.month, born.day)))

        if age < 14:
            msg = ("Sorry, you must be atleast 14 years old")
            self.add_error('dob', msg)

        if age > 110:
            msg = ("You entered a date of birth outside of the accepted range. Please try again.")
            self.add_error('dob', msg)

        return data

models.py

dob = models.DateTimeField('Date of birth (mm/dd/yyyy)', null=True, default=now)

我的问题是，此错误消息以Flash消息形式显示在页面顶部，而其他消息（我未设置但却内置了脆性消息，例如当用户将必填字段留空时）会显示作为与错误相关的字段下的弹出消息框。

我想知道如何使添加的验证错误与其他内置的酥脆错误消息相同，以保持一致性。

如果您要覆盖干净方法，则可以使用add_error()：

def clean(self):
    data = self.cleaned_data
    age = data.get("age")

    if age < 14:
        msg = "Sorry, you must be atleast 14 years old to study with IPC IELTS."
        self.add_error('age', msg)

    if age > 110:
        msg = "You entered a date of birth outside of the accepted range. Please try again."
        self.add_error('age', msg)

    return data

您还可以在模型或表单上进行验证：

from django.core.validators import MinValueValidator,MaxValueValidator
from django.utils.translation import ugettext_lazy as _

class YourModel(models.Model):
    age = models.DecimalField(..., validators=[
        MinValueValidator(14, message=_("Sorry, you must be atleast 
            14 years old to study with IPC IELTS.")),
        MaxValueValidator(110, message=_("You entered a date of birth outside of the 
            accepted range. Please try again."))
    ])

因此您无需为该字段手动设置样式。

以与错误消息相同的样式显示验证错误
