用户creationform验证不起作用django

一切似乎都可以正常工作，但是如果表单没有验证，而不是获得HTML验证错误，我会得到 valueerror ar /register /：user.register不会返回httpresponse。它没有返回。

我的代码：

if request.method == 'POST':
   form = UserCreationForm(request.POST)
   if form.is_valid():
      form.save()
      messages.success(request, 'Acount created!')
else:
   form = UserCreationForm():
   return render(request, 'users/register.html', {"form":form})

原文

Everything seems to be working fine, but if the form doesn't validate, instead of getting HTML validation errors, I get ValueError ar /register/: The user.register didn't return an HTTPResponse. It returned none instead.

My code:

if request.method == 'POST':
   form = UserCreationForm(request.POST)
   if form.is_valid():
      form.save()
      messages.success(request, 'Acount created!')
else:
   form = UserCreationForm():
   return render(request, 'users/register.html', {"form":form})

通常，在每个API调用上返回响应，

例如

import json
from django.http import HttpResponse

def profile(request):
    data = {
        'name': 'Vitor',
        'location': 'Finland',
        'is_active': True,
        'count': 28
    }
    dump = json.dumps(data)
    return HttpResponse(dump, content_type='application/json')

尝试根据django的任何响应添加返回语句，根据您尝试返回的内容，

您需要在块上添加类似的响应

usually response are returned on each api call

import json
from django.http import HttpResponse

def profile(request):
    data = {
        'name': 'Vitor',
        'location': 'Finland',
        'is_active': True,
        'count': 28
    }
    dump = json.dumps(data)
    return HttpResponse(dump, content_type='application/json')

try to add return statement with any of Response from django based on what you try to return

you need to add similar to this on if block
