Question

我在电子商务应用中无法显示Django的内容。这是只有导航栏的基本URL：

var list = (from user in _db.TableUser
    let r = _db.TableLink.FirstOrDefault(l => l.ProjectId == projectId && l.UserId  == user.UserId)
    let t = _db.TableTeam.FirstOrDefault(m => m.ManagerId == user.ManagerId)
    where user.EndDate == null && user.ManagerId != null && managerIds.Contains(user.ManagerId.Value) 
    && r != null && t != null
    select new MyDto
    {
        ProjectId = projectId,
        UserId = user.UserId,
        IsAssigned = r.AssignedId > 0 ?true : false,
        AssignedId = r.AssignedId,
        Percent = r.Percent.HasValue ? (r.Percent.Value).ToString() + "%": ""
    }).GroupBy(d => d.UserId).ToList();

如您所见，我具有{% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="{% static 'css/style_store.css' %}"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <title>Inicio</title> </head> <body> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="#">Mi ecommerce</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Inicio<span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> </ul> <ul class="navbar-nav mr-auto"> <form class="form-inline my-4"> <input class="form-control mr-sm-2" type="search" placeholder="Buscá productos" aria-label="Search"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button> </form> </ul> <ul class="navbar-nav"> {% if user.is_authenticated %} <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> {{ user }} </a> <div class="dropdown-menu" aria-labelledby="navbarDropdown"> <a class="dropdown-item" href="#">Mi perfil</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Ventas</a> <a class="dropdown-item" href="#">Compras</a> </div> </li> {% else %} <li class="nav-item"> <a class="nav-link" href="{% url 'login' %}">Logueate</a> </li> {% endif %} </ul> </div> </nav> {% block content %} {% endblock content %} <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"></script> </body> </html>标签，因此可以使用主页扩展此网站。这是home.html：

{% block content %}

问题是我看不到“ HelloWorld”，只能看到基本html的导航栏。任何帮助将不胜感激！

您需要将内容放入扩展模板中定义的块中，以使其呈现。在这种情况下，content块

{% extends 'store/store.html' %}

{% block content %}
    <h1>HelloWorld</h1>
{% endblock content %}

“父”模板中的块定义了可以在扩展模板中插入内容的部分，您需要在扩展模板中使用{% block %}来告诉渲染器要将内容放入哪个部分。 {% block %}以外的任何内容都不会呈现

使用Django扩展模板不起作用
