问题描述

当我向我的子模板（父为base.html）添加 {％extendsX.html％} 时，只有父模板被加载。当我拿走它，孩子模板被加载。我有另一个应用程序，我有一个看似相同的继承结构，所以我被骗了。这是base.html：

 <！DOCTYPE html> 
 {％load staticfiles％} 
< html> 
< head> 
 {％block js％} 
< script src ={{STATIC_URL}} js / jquery.1.12.4.min.js>< / script> 
< script src ={{STATIC_URL}} js / p5.js
 {％endblock％} 
< title> myapp< / title> 
< / head> 
< body> 
< h1>欢迎使用我的应用< / h1> 
< / body> 
< / html>

这是grow.html

 <！DOCTYPE html> 
 {％extendsapp / base.html％} 
 {％block js％} 
< script src ={{STATIC_URL}} js / grow.js>< ; /脚本> 
 {％endblock％} 
 {％block content％} 
< body> 
< div id =messagestyle =visibility：hidden;>< / div> 
< div id =tree>< / div> 
< a href =/ register /> register< / a> 
< form method =POST> 
 {％csrf_token％} 
< input type =textid =txt/> 
< input type =submitid =growvalue =growstyle =color：gray/> 
< / form> 
< / body> 
 {％endblock％}

我绝对在我的views.py中调用子模板，所以这不是问题：

  def grow（request）：
 ... 
 return render （请求'app / grow.html'）

这是我的项目网址：

from django.conf.urls import include，url
from django.contrib import admin
from app import views

  urlpatterns = [
 url（r'^ admin /'，admin.site.urls），
 url（r'^ grow /'，include （'app.urls'）），
 url（r'^ $'，views.home，name =home），
] 
  pre> 
 
 和应用程序网址：
  from django.conf.urls从应用程序导入视图导入url 
 
 
 urlpatterns = [
 url（r'^ $'，views.grow，name ='grow'），
 
] 
  
当我去url / grow /我期待看到grow.html 但我看到base.h tml
解决方案
您的基本模板不包含内容块。所以它是继承，它只是没有地方坚持块。 
 
 
 只需添加内容块。
 < / head> 
 {％block content％} 
< body> 
< h1>欢迎使用我的应用< / h1> 
< / body> 
 {％endblock content％} 
< / html> 
  
 
When I add {% extends "X.html" %} to my child templates (the parent being "base.html"), only the parent template is loaded.  When I take it away, the child template is loaded.  I have another app where I have a seemingly identical inheritance structure, so I'm stumped.  Here is "base.html":
<!DOCTYPE html>
{% load staticfiles %}
<html>
  <head>
    {% block js %}
    <script src="{{ STATIC_URL }}js/jquery.1.12.4.min.js"></script>
    <script src="{{ STATIC_URL }}js/p5.js"
    {% endblock %}
    <title>myapp</title>
  </head>
  <body>
    <h1>Welcome to my app</h1>
  </body>
</html>
Here is "grow.html"
<!DOCTYPE html>
{% extends "app/base.html" %}
{% block js %}
  <script src="{{ STATIC_URL }}js/grow.js"></script>
{% endblock %}
{% block content %}
<body>
  <div id="message" style="visibility: hidden;"></div>
  <div id="tree"></div>
  <a href="/register/">register</a>
<form method="POST">
  {% csrf_token %}
  <input type="text" id="txt" />
  <input type="submit" id="grow" value="grow" style="color: grey;"/>
</form>
</body>
{% endblock %}
I am definitely calling the child template in my views.py, so that's not the problem:
def grow(request):
    ...
    return render(request, 'app/grow.html')
Here are my project urls:
from django.conf.urls import include, urlfrom django.contrib import adminfrom app import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^grow/', include('app.urls')),
    url(r'^$', views.home, name="home"),
    ]
and app urls:
from django.conf.urls import url
from app import views

urlpatterns = [
    url(r'^$', views.grow, name='grow'),

    ]
When I go to the url /grow/ I am expecting to see "grow.html" but I am seeing "base.html".
 解决方案 
Your base template doesn't contain a content block. so it is inheriting, it just has nowhere to stick the block. 
Simply add the content block.
  </head>
{% block content %}
  <body>
    <h1>Welcome to my app</h1>
  </body>
{% endblock content %}
</html>
