姜戈：查看"didn't return an HttpResponse object"

Question

我收到以下错误，因为在提交表单时没有返回httpresponse对象，我真的不明白为什么：

Exception Type: ValueError at /contact/addcontact
Exception Value: The view openshift.contactapplication.views.contact didn't return an HttpResponse object.

这是我的观点：

# Create your views here.
from django.shortcuts import render_to_response, render
from django.http import HttpResponseRedirect, HttpResponse
#forms imports
from contactapplication.forms import applicantsForm
#model imports
from contactapplication.models import applicantsModel
def contact(request):
if request.method == 'POST':
    form = applicantsForm(request.POST)
    if form.is_valid():
        clean_form =form.cleaned_data
        collect = applicantsModel(first_name=clean_form['first_name'], last_name=clean_form['last_name'],
            linkedin_profile=clean_form['linkedin_profile'], elevator_pitch=clean_form['elevator_pitch'],
            email=clean_form['email'], phone=clean_form['phone'])
        collect.save()
        return HttpResponseRedirect('contactUs/contactUs.html') #the same page, change to thankyou page later

else:
    return render(request, 'contactUs/contactUs.html',)

可能是什么问题？我清楚地返回了一个HttpResponseRedirect

Answer 1

如果方法是POST并且表单有效，则返回HttpResponseRedirect。若方法不是POST，则返回render()的结果，这是一个HttpResponse。到目前为止还不错。

但是，如果方法是POST，并且表单无效，则不显式返回任何内容（因此返回None）。

这是假设我的缩进是正确的——在你的问题中有点错误，例如def下的代码没有缩进。
