我无法从数据库信息中显示我的图像文件。如果我直接输入文件名,它可以正常工作,但代码显示损坏的图像。非图像变量工作正常,图像作为文件名的 CharField 存储在模型中(我现在意识到这可能不是最好的,但我认为改变可能为时已晚?)我做错了什么?
<div class="product_image" >
{% load static %} <img src="{% static "images/{{p.image.url}}" %}" alt={{p.name}}/>
(我也试过 {{p.image}} 没有运气。)
以下是相关设置——仍然对媒体与静态感到困惑。
MEDIA_ROOT = os.path.join(os.path.dirname(__file__), 'media')
# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL = '/media/'
# Absolute path to the directory static files should be collected to.
# Don't put anything in this directory yourself; store your static files
# in apps' "static/" subdirectories and in STATICFILES_DIRS.
# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT = os.path.join(os.path.dirname(__file__), 'staticcoll')
# URL prefix for static files.
# Example: "http://media.lawrence.com/static/"
STATIC_URL = '/static/'
# Additional locations of static files
STATICFILES_DIRS = (
# Put strings here, like "/home/html/static" or "C:/www/django/static".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
os.path.join(os.path.dirname(__file__), 'static'),
)
