python - 无法从 DJANGO 获取输入/输出

问题描述

我是 Django 的新手。在练习时。我下载了 HTML 模板并设法修改它以加载 django。我的问题是我无法从 Django<>HTML 获得任何输入或输出。我不知道问题出在哪里。

视图.py

from django.shortcuts import render

    def home(request):
        return render(request, 'home.html' ,{})

    def contact(request):
        if request.method == "POST" :
            username_1 = request.POST["username"]
            return render(request, 'home.html', {'username_1' : username_1})

login_page/urls.py

    from django.urls import path
    from . import views


    urlpatterns = [
        path('', views.home, name="home"),

    ]

文件夹树：我的 DJANGO 文件夹树屏幕截图

我想要做的是用户名输入并将它们重定向到 html 中的 {{ username_1 }} 。

更新 1：我将 urls.py 和 html 修改为以下内容，同样的问题。

意见。

from django.urls import path
from . import views


urlpatterns = [
    path('', views.home, name="home"),
    path('', views.home, name="contact"),

]

html

        <form class="login100-form validate-form" action="{% url 'contact' %}" method="post"  >
            {% csrf_token %}
            <span class="login100-form-title">
                {{ username_1 }}
            </span>
