你有两个else:条件。这不是有效的语法。转到您提供的链接，您会出现缩进错误。应该是这样的。一个用于内部if-else，另一个用于外部if-else。

    if request.method == 'POST':
            form = RegistrationForm(request.POST)
            if form.is_valid():
                    user = User.objects.create_user(username=form.cleaned_data['username'], email = form.cleaned_data['email'], password = form.cleaned_data['password'])
                    user.save()
                    drinker = Drinker(user=user, name=form.cleaned_data['name'], birthday=form.cleaned_data['birthday'])
                    drinker.save()
                    return HttpResponseRedirect('/profile/')
            else:
                    return render_to_response('register.html', {'form': form}, context_instance=RequestContext(request))
    else:
            ''' user is not submitting the form, show them a blank registration form '''
            form = RegistrationForm()
            context = {'form': form}
            return render_to_response('register.html', context, context_instance=RequestContext(request))
