Question

我试图在用户输入后从我的views.py重定向到另一个URL-视图实际上发生了变化，但是不幸的是，浏览器的URL保持不变。

urls.py：


path('start/', StartProject.as_view(), name='start_url'),

path('settings_1/', settings_1_view, name='settings_1_url'),

path('settings_2/', settings_2_view, name='settings_2_url'),

path('settings_3/', settings_3_view, name='settings_3_url'),

我的views.py：在这里，我尝试在选择后将用户重定向到另一个页面。

views.py


class StartProject(TemplateView):

    template = "start.html"

    def get(self, request):
        class_form = ClassChoiceForm(request.POST or None, initial={'class_select': 1})
        context = {
            'class_form': class_form
        }
        return render(request, self.template, context)

    def post(self, request):
        class_form = ClassChoiceForm(request.POST)
        if class_form.is_valid():
            choice = class_form.cleaned_data['class_select']
            choice = int(choice)

            if choice == 1:
                return redirect('settings_1/')

            elif choice == 2:
                return redirect('/settings_2/')

            elif choice == 3:
                return redirect('/settings_3/')

            else:
                self.get(request)

        else:
            raise Http404


def settings_1_view(request):
    context = {
    }
    template = "settings_1.html"
    return render(request, template, context)

通过单选按钮进行用户选择，该值将发布到views.py /在if-语句中检查该值，它将用户重定向到所选页面。（我需要用户选择以进行进一步的计算）

POST模板choice.html：

{% extends "base.html" %}
{% load staticfiles %}
{% load static %}

{% block title %} TITLE {% endblock %}
{% block content %}

        </div>
            </center>
    </div>

{% endblock content %}

forms.py

class ClassChoiceForm(forms.Form):
    CHOICES = [
        (1, 'item1'),
        (2, 'item2'),
        (3, 'item3')
                ]
    class_select = forms.CharField(label=None, widget=forms.RadioSelect(choices=CHOICES))

它确实从表单获取用户输入，采用正确的路径，显示它，但未更改浏览器中的相关URL。因此，如果我刷新页面，则会加载旧页面。有人有想法吗？
