django自定義錯誤處理

要實現自定義錯誤處理的功能，總共分4步： 

1.創建html錯誤頁 

2.配置settings ，當DEBUG=True，則不會生效

3.編寫視圖 

4.配置url

 

 

 

 

views.py

def page_not_found(request,exception):
    #404
    return render(request,"blog/404.html",status=404)

def page_error(exception):
    
    return render("blog/500.html",status=500)

def permission_denied(request,exception):
    #403
    return render(request, "blog/403.html",status=403)

def bad_request(request,exception):
    #400
    return render(request, "blog/400.html",status=400)

主程序下urls.py

handler400 = views.bad_request
handler403 = views.permission_denied
handler404 = views.bad_request
handler500 = views.page_error

然后運行：

 

 

 過程中可能遇到的報錯：

# ERRORS:?: (urls.E007) The custom handler500 view 'blog.views.page_error' does not take the correct number of arguments (request).
解決：視圖函數中不要request參數

def page_error(exception):
    #500
    return render("blog/500.html")

 

# ERRORS:?: (urls.E007) The custom handler403 view 'blog.views.permission_denied' does not take the correct number of arguments (request, exception).

 解決：視圖函數中加上exception參數，雖然沒什么用

def permission_denied(request,exception):
    #403
    return render(request, "blog/403.html")
