【问题描述】：

我收到 django 媒体文件的错误代码 404。 urs.py如下：

 from django.conf.urls import patterns,include, url
    from django.views.static import serve

    from django.contrib import admin
    #import settings
    from django.conf.urls.static import static
    from django.conf import settings
    admin.autodiscover()

    urlpatterns = patterns('',
        # Examples:
        # url(r'^$', 'timesheet_tool.views.home', name='home'),
        # url(r'^blog/', include('blog.urls')),
        url(r'^admin/', include(admin.site.urls)),
        url(r'^welcome_page/', include('welcome_page.urls')),
        url(r'^add_status/', include('add_status.urls')),
        url(r'^view_status/', include('view_status.urls')),

    )

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

views.py：

from django.http import HttpResponse
from django.shortcuts import render
from django.template import loader
from django.template import RequestContext

def index(request):
        return render(request, 'welcome.html', 'welcome_message':"Welcome "+get_user_name()+"!!!")

def get_user_name():
        user_name = "Brad"
        return str(user_name)

html 模板：

我也经历过其他线程“Page not found 404 Django media files”，但它没有帮助我。

【问题讨论】：

SETTINGS_PATH 它由什么组成？并至少正确命名文件夹，使用媒体而不是模板以便更好地理解

您尝试从哪里检查媒体文件？

来自 /welcome_page/，我已将图像/媒体包含在其中。我从浏览器控制台看到了 404 错误代码。

贴出模板和视图的代码

添加有问题

【参考方案1】：

我已经通过使用静态方法解决了我的问题。 我已将静态文件夹放在 view_status 目录中。 所以在 /view_status/static/ 里面我放了 logo.png 和其他图片。

现在我已将模板更改如下：

% load static % 
<a href="/add_status" class="addStatusButton">Add Status </a>
<a href="/view_status/?page=0&e_date=&s_date=&type=date" class="viewStatusButton">View Status </a>
<a href="#" class="viewReportButton">View Report </a>
<a href="#" class="logOutButton">Logout</a>
<div style="display: flex; justify-content:center;">
   <img src = "% static 'logo.png' %"  >
   <img src = "% static 'Timesheets.png' %"  >
</div>
<h2><span>DASHBOARD</span></h2>
<p>welcome_message</p>
<style>
   p    color: green;
   adding:23px 200px;
   position: absolute;top:130px;left:100px;
   h2 
   width: 100%; 
   text-align: center; 
   color:#35a5f0;
   line-height: 1em;
   margin: 10px 0 20px; 
   background-color:#35a5f0;
    
   h2 span  
   background:#fff; 
   padding:0 10px; 
   
   div.dashBoard 
   color:#35a5f0;
   font-family: 'Tangerine', serif;
   position:absolute;top:300px;left:700px;
   width: 200px; 
   height: 100px; 
   overflow-y: scroll;
   
   .addStatusButton,.viewStatusButton,.viewReportButton,.logOutButton 
   -moz-box-shadow: 0px 0px 0px 0px #3dc21b;
   -webkit-box-shadow: 0px 0px 0px 0px #3dc21b;
   box-shadow: 0px 0px 0px 0px #3dc21b;
   background-color:#35a5f0;
   -moz-border-radius:35px;
   -webkit-border-radius:35px;
   border-radius:28px;
   border:1px solid #ffffff;
   display:block;
   cursor:pointer;
   color:#ffffff;
   font-family:Arial;
   font-size:17px;
   padding:23px 200px;
   text-decoration:none;
   text-shadow:0px 0px 0px #2f6627;
   font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
   
   .addStatusButton
   position:absolute;top:200px;left:100px;
   
   .addStatusButton:hover 
   background-color:#72cf40;
   
   .viewStatusButton
   position:absolute;top:300px;left:100px;
   
   .viewStatusButton:hover     
   background-color:#72cf40;
   
   .viewReportButton
   position:absolute;top:400px;left:100px;
   
   .viewReportButton:hover     
   background-color:#72cf40;
   
   .logOutButton
   position:absolute;top:500px;left:100px;
   
   .logOutButton:hover     
   background-color:#72cf40;
   
</style>

在 setting.py 我添加了以下内容：

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

在 urls.py 我添加了以下内容：

urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

我知道 django 会从 INSTALLED_APPS 中搜索静态文件夹。所以我已将静态文件夹放在 INSTALLED_APPS 之一中，在我的例子中是 view_status。

现在它工作正常。 感谢“Exprator”的大力帮助和支持。
