模板不存在 django

我所做的是将多个应用程序放入另一个应用程序中。我让他们通过名字系统互相交谈。我仍然必须为数据库做外键和所有事情。

但是，我在 couresapp 上的urls.py中有一条路线，并且有一个用于相同渲染的视图并将我带到页面。当我单击成功页面上的目录按钮时，它给我一个错误，找不到页面。

希望第二双眼睛可以看到并解决这个问题：

课程 urls.py 应用程序

from django.conf.urls import url
from . import views
urlpatterns = [
  url(r'^$', views.index, name= 'index'),
  url(r'^user$', views.create, name='success'),
  url(r'^usercourses$', views.usercourses, name='usercourses')
]

课程 views.py 应用程序

def usercourses(request):

    context ={
        "courses": User.objects.all(),
    }
    return render (request, "coursesapp/users_courses.html", context )

HTML for Coures app

   <body>
        <form class="" action="{% url 'courses:usercourses' %}" method="post">
      <p>  Test <option value="{{user.course_name}}"></option> Test
        Test <option value="{{user.course_name}}"></option> Test

            <input type="submit" name="" value="Add">
        </form>
  {% for user in courses%}
     <p>{{user.course_name}} {{user.description}} {{created_at.description}}</p>
      {% endfor%}
    </body>

登录应用程序中成功页面中将我带到课程应用程序的表单的 HTML

    <form class="" action="{% url 'courses:usercourses' %}"  method="post">
            {% csrf_token %}
        <input type="submit" name="Logout" value="Catalog">
    </form>
</html>

回溯抱歉福戈特包括这个

问题的答案是课程中的额外 s

在 views.py 目录中，将 C：以来的路径输入到模板文件夹，并使用双反斜杠*

*因为 \u 是 Unicode 转义

 return render(request,"C:\Users\You\templates\test.html",{})
