在Django中的sorl-thumbnail admin使用AdminImageMixin

Question

我試圖使用sorl-thumbnail v11.12在Django管理員中顯示縮略圖。

我models.py已經使用sorl.thumbnail.ImageField按照文檔：

Note You do not need to use the sorl.thumbnail.ImageField to use sorl.thumbnail. The standard django.db.models.ImageField is fine except that using the sorl.thumbnail.ImageField lets you plugin the nice admin addition explained in the next section. 

不過，我不能確定如何配置admin.py。我已經完成了manage.py syncdb。目前，我有以下內容，但不會在Django admin中顯示縮略圖。

MyProject的/ admin.py

from django.contrib.admin import * 
from sorl.thumbnail.admin import AdminImageMixin 

class ModelAdmin(AdminImageMixin, ModelAdmin): 
    pass 

class TabularInline(AdminImageMixin, TabularInline): 
    pass 

class StackedInline(AdminImageMixin, StackedInline): 
    pass 

MyProject的/ MyApp的/ admin.py

from MyProject import admin 
from myapp.models import Tours 

class ToursAdmin(admin.ModelAdmin): 
    list_display = ('name', 'image', 'price') 
    search_fields = ('name',) 

admin.site.register(Tours, ToursAdmin)

# models.py 
class Tours(models.Model): 
    image = models.ImageField(upload_to="path/") 

    def thumb(self): 
     return u'<img src="%s" />' % (get_thumbnail(c, "50x50", crop='center', quality=95).url) 
    thumbs.short_description = 'Photos' 
    thumbs.allow_tags = True 

# admin.py 
class ToursAdmin(admin.ModelAdmin): 
    list_display = ('name', 'thumb', 'price')
