Question

我正在尝试将图像添加到非常基本的html模板中。我能够渲染html文件，但遗憾的是图像不会显示。

这是我的错误：

Not Found: /exapp/pic.jpg
[21/Apr/2018 18:43:49] "GET /exapp/pic.jpg HTTP/1.1" 404 2145

我注意到django正在寻找带有/exapp/pic.jpg路径的文件，所以我在静态目录中创建了一个名为exapp的文件夹，并将图像放在那里。仍然没有图像:(

文件结构如下：

    ─ db.sqlite3
├── exapp
│   ├── admin.py
│   ├── apps.py
│   ├── __init__.py
│   ├── migrations
│   │   ├── __init__.py
│   │   └── __pycache__
│   │       └── __init__.cpython-35.pyc
│   ├── models.py
│   ├── __pycache__
│   │   ├── admin.cpython-35.pyc
│   │   ├── __init__.cpython-35.pyc
│   │   ├── models.cpython-35.pyc
│   │   ├── urls.cpython-35.pyc
│   │   └── views.cpython-35.pyc
│   ├── static
│   │   └── exapp
│   │       └── pic.jpg
│   ├── templates
│   │   └── index.html
│   ├── tests.py
│   ├── urls.py
│   └── views.py
├── manage.py
└── mysite
    ├── __init__.py
    ├── __pycache__
    │   ├── __init__.cpython-35.pyc
    │   ├── settings.cpython-35.pyc
    │   ├── urls.cpython-35.pyc
    │   └── wsgi.cpython-35.pyc
    ├── settings.py
    ├── urls.py
    └── wsgi.py

以下是有问题的HTML文件：

    <html>
    <head> 
        <title> Hello world</title>
    </head>

    <body>
        Look it worked 
    {% load static %}
    <img src="pic.jpg" alt="Smiley face" height="200" width="420">
    </body>

</html>

以下是设置文件：

以下是我的观点和网址文件：

 ---------url.py in mysite folder------------
    from django.contrib import admin
    from django.urls import path, include

    urlpatterns = [
        path('admin/', admin.site.urls),
        path('exapp/',include('exapp.urls')),
    ]
    -----------urls.py in exapp folder--------------
    from django.urls import path


    from . import views 

    urlpatterns = [
        path('', views.index, name='index'),
    ]

 ----------Views in exapp folder--------------------------
    from django.shortcuts import render

    # Create your views here.
    from django.http import HttpResponse


    def index(request):
        return render(request,'index.html')

因此，作为一个纲要，HTML模板会渲染到页面。但我出于某种原因无法弄清楚如何将html代码中链接的图像显示到屏幕上。一切似乎都在正确的地方。谢谢你的帮助！

Answer 1

您应该尝试更改图片来源。

这就是你所拥有的：

<img src="pic.jpg" alt="Smiley face" height="200" width="420">

试试这个：

<img src="{% static "exapp/pic.jpg" %}" alt="Smiley face" height="200" width="420">

这对我有用！

祝你好运！
