有什麼辦法在管理網站那樣？：推出自定義錯誤

目前我把與

raise forms.ValidationError('error') 

但錯誤顯示調試錯誤屏幕

Answer 1

你在哪裏把raise forms.ValidationError('error')？

在你的表單中，clean（）方法是引發自定義錯誤的好地方。您甚至可以執行def clean_fieldname()來對一個字段進行特定驗證。從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
