我是Django的新手，并且一直在我的项目中使用它，直到遇到一个很小的问题，这个问题虽然很小，但从两天后开始困扰我。如何在Django模板中应用背景图片？
这是我的index.html：-

我将我的STATICFILES_DIR = [STATIC_DIR,]设置为STATIC_DIR = os.path.join(BASE_DIR, 'static')
我的项目文件夹中有一个静态文件夹，而里面是图像文件夹。但是经过这么多尝试，我仍然无法解决此背景图片问题。
永远都不会太晚回答。错误的一种可能来源：语法错误。应该是：
background-image: url({% static "images/dumb2.jpg" %});
不是
background: url({% static "images/dumb2.jpg" %});
