Django sorl.缩略图未在管理面板中显示img

我使用的是django 1.10和last sorl.thumbnail 这是我的型号。py

from sorl.thumbnail import ImageField
class StockImage(models.Model):
    image = models.ImageField(upload_to='stock', blank=True, null=True,
                              verbose_name=_('Image'))

from sorl.thumbnail.admin import AdminImageMixin
class StockImageInline(AdminImageMixin, admin.StackedInline):
    model = StockImage
    extra = 1    

@admin.register(Stock)
class StockAdmin(TranslationAdmin):
    group_fieldsets = True
    list_display = ('title', 'city', 'start_date', 'finish_date', 'unlimited', 'publish')
    inlines = [
        StockImageInline,
    ]

这里是admin.py

from sorl.thumbnail import ImageField
class StockImage(models.Model):
    image = models.ImageField(upload_to='stock', blank=True, null=True,
                              verbose_name=_('Image'))

from sorl.thumbnail.admin import AdminImageMixin
class StockImageInline(AdminImageMixin, admin.StackedInline):
    model = StockImage
    extra = 1    

@admin.register(Stock)
class StockAdmin(TranslationAdmin):
    group_fieldsets = True
    list_display = ('title', 'city', 'start_date', 'finish_date', 'unlimited', 'publish')
    inlines = [
        StockImageInline,
    ]

原因是在旧的“枕头”版本。谢谢。你升级到了什么版本的枕头？我对Python 3.5.2也有同样的问题，sorl缩略图==12.3，枕头==4.1.1Python3.6通过此链接安装sorl“-e git+”枕头-4.0.0原因是在旧的“枕头”版本中。谢谢。你升级到了什么版本的枕头？我在Python3.5.2中遇到了同样的问题，sorl缩略图==12.3，枕头==4.1.1Python3.6通过以下链接安装sorl“-e git+”枕头-4.0.0
