有什么办法在管理网站那样？：推出自定义错误

目前我把与

但错误显示调试错误屏幕

Answer 1

你在哪里把raise forms.ValidationError('error')？

在你的表单中，clean（）方法是引发自定义错误的好地方。您甚至可以执行def clean_fieldname()来对一个字段进行特定验证。从django docs

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
