Django 管理员并显示缩略图

问题描述

我正在尝试在 Django 管理中显示缩略图，但我只能看到图像的路径，而不是渲染的图像.我不知道我做错了什么.

I'm trying to show thumbnail images in Django admin, but I can only see the path to the images, but not the rendered images. I don't know what I'm doing wrong.

服务器媒体网址:

from django.conf import settings
(r'^public/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),

功能模型:

def image_img(self):
        if self.image:
            return u'<img src="%s" />' % self.image.url_125x125
        else:
            return '(Sin imagen)'
        image_img.short_description = 'Thumb'
        image_img.allow_tags = True

admin.py:

class ImagesAdmin(admin.ModelAdmin):

    list_display= ('image_img','product',)

结果:

<img src="http://127.0.0.1:8000/public/product_images/6a00d8341c630a53ef0120a556b3b4970c.125x125.jpg" />

解决方案

这在 photologue(参见 models.py，稍作修改以删除不相关的内容):

This is in the source for photologue (see models.py, slightly adapted to remove irrelevant stuff):

def admin_thumbnail(self):
    return u'<img src="%s" />' % (self.image.url)
admin_thumbnail.short_description = 'Thumbnail'
admin_thumbnail.allow_tags = True

list_display 位看起来也一样，我知道这很有效.对我来说唯一可疑的是您的缩进-在 models.py 代码末尾以 image_img 开头的两行应该与 def image_img(self):，像这样:

The list_display bit looks identical too, and I know that works. The only thing that looks suspect to me is your indentation - the two lines beginning image_img at the end of your models.py code should be level with def image_img(self):, like this:

def image_img(self):
    if self.image:
        return u'<img src="%s" />' % self.image.url_125x125
    else:
        return '(Sin imagen)'
image_img.short_description = 'Thumb'
image_img.allow_tags = True
