Django xadmin实现一次性选择多张图片并存储的一个方法, 以及详情页面多图展示

代码结构图

直接上源码

models.py设置如下

class picture(models.Model):
    imgs = UploaderImageField(max_length=500, verbose_name='活动图片', null=True, blank=True, upload_to='image/')    #文件

#单图的设置
class Img(models.Model):
    model = models.ForeignKey(Dsj,on_delete=models.CASCADE,verbose_name='单图')
    creattime = models.DateTimeField(verbose_name='创建时间', default=datetime.now)
    image = models.ImageField(upload_to='image/', verbose_name='图片', null=True, blank=True)
    class Meta:
        verbose_name = u'单张图'
        verbose_name_plural = verbose_name

widgets.py设置如下
