django - 通知错误

Question

有没有办法在这样的管理站点中启动自定义错误？：

目前我抛出错误

raise forms.ValidationError('error')

但显示调试错误屏幕

Answer 1

你把它放在哪里raise forms.ValidationError('error')？

在您的表单中，clean() 方法是引发自定义错误的好地方。您甚至可以def clean_fieldname()对一个字段执行特定验证。来自django 文档

from django import forms

    class ContactForm(forms.Form):
        # Everything as before.
        ...

        def clean_recipients(self):
            data = self.cleaned_data['recipients']
            if "fred@example.com" not in data:
                raise forms.ValidationError("You have forgotten about Fred!")

            # Always return the cleaned data, whether you have changed it or
            # not.
            return data
