Question

我所做的是将多个应用程序放入另一个应用程序。我让他们通过名称系统互相交谈。我仍然需要为数据库做外键和所有操作。

但是我在couresapp上的urls.py中有一条路线，并且有相同渲染的视图，并将我带到了该页面。当我单击成功页面上的目录按钮时，它会向我显示无法找到页面的错误。

希望第二双眼睛可以看到并解决这个问题：

urls.py for courses app

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')
]

views.py for courses app

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>

html，用于登录应用中成功页面中的表单，该表格将我带到了课程应用

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

</html>

Answer 1

问题的答案是课程中的额外内容

Answer 2

在views.py目录中，将自C：之后的路径放到模板文件夹中，并使用双反斜杠*

*因为\ u是Unicode转义

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

模板不存在django
