更改密码Django

Question

我有以下功能来更改密码并显示用户配置文件，但是在提交表单而不是被重定向到'profile/'页面时出现错误，说明为The view core.views.change_password didn't return an HttpResponse object. It returned None instead.，这是为什么？

from django.contrib.auth.forms import UserChangeForm, PasswordChangeForm 
from django.contrib.auth import update_session_auth_hash 

def change_password(request): 
    if request.method == "POST": 
     form = PasswordChangeForm(data= request.POST, user = request.user) 

     if form.is_valid(): 
      form.save() 
      update_session_auth_hash(request, form.user) #this function keeps the user logged in afte they change their password 
      # request.user could not have been passed in because that would pass in 'AnonymousUser', however 
      #form.user gets the user who was filling in the form and passes it to the function 
      return redirect('/profile') 
    else: 
     form = PasswordChangeForm(user = request.user) 
     args = {'form': form} # gives access to the form in the template 
     return render(request, 'core/change_password.html', args) 

def view_profile(request): 
    args = {'user': request.user} # 
    return render(request, 'core/profile.html', args) 

注：个人资料页并在用户登录被重定向到他们的个人资料页，没有问题后，对网站中的其他部分，例如。

您应该将最后两行移出else块。这样，当表单无效时，您将返回POST请求的响应。

def change_password(request): 
    if request.method == "POST": 
     form = PasswordChangeForm(data= request.POST, user = request.user) 

     if form.is_valid(): 
      ... 
      return redirect('/profile') 
    else: 
     form = PasswordChangeForm(user = request.user) 
    args = {'form': form} # gives access to the form in the template 
    return render(request, 'core/change_password.html', args)
