问题描述

我试图在Django管理员中显示缩略图,但是我只能看到图像的路径,而不是渲染的图像。我不知道我在做错什么。



服务器媒体网址:

 code>从django.conf导入设置
(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
/ pre>

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

这是源于 photologue (见 models.py ,稍微适应删除不相关的东西):

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

list_display 位看起来是一样的,我知道这是有用的。对我来说唯一看起来是你的缩进 - 在 models.py image_img >代码应该与 def image_img(self):等级,如下所示:

  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


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.

Server media URL:

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

Function model:

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',) 

And the result:

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

解决方案

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

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
