通过视图将图像从一个模型获取到第二个模型并在枕头中复制并保存到新路径，如何在 html 中获取新路径 img 和旧路径 img

如何解决通过视图将图像从一个模型获取到第二个模型并在枕头中复制并保存到新路径，如何在 html 中获取新路径 img 和旧路径 img

'''

class generated_certificates(models.Model):
    certifyuser = models.ForeignKey(User,related_name = "generated_certificates",on_delete=models.SET_NULL,null=True)
    cerficpic = models.ImageField(upload_to = 'pictures/generatedslips',null = True,blank = True)
    cerficpic2 = models.ImageField(upload_to = 'pictures/generatedslips',blank = True)
    cerficpic3 = models.ImageField(upload_to = 'pictures/generatedslips',blank = True)
    description = models.TextField(null = True)
    timestamp = models.DateTimeField(auto_Now_add = True)
    

    def save(self,*args,**kwargs):

        userdata = self.certifyuser
        userprofile = profileforsurvay.objects.get(user = userdata)
        userrating = str(userprofile.total_rating)
        usertotalviews = str(userprofile.viewcounts)
        usergrade = str(gradcounter(userdata))
        stamp = stampgenerator(usergrade,userrating,usertotalviews)
        if self.cerficpic:
            initial_path = self.cerficpic.path
            imag = self.cerficpic

            ext = initial_path.split('.')[-1]
            filename = "%s.%s" % (userdata,ext)
            new_path=os.path.join(os.path.dirname(initial_path),"generatedslips/",filename)
            print(new_path)
            newimg = paststamp(imag,stamp)
            newimg.name=imag.name
            newimg.path=new_path
            newimg.save(newimg.path)
            super().save(*args,**kwargs) 
           #image saved to newpath but how to get newpath img in html template
           # if you see template code it show oldpath img

我从其他名为 profileforsurvay 的模型复制图像的视图#

def generate_slip(request):
    profile = profileforsurvay.objects.get(user = request.user)
    img = profile.userpics.pic
    img2 = profile.userpics.pic2
    img3 = profile.userpics.pic3
    description = profile.description
    latests = generated_certificates(certifyuser = request.user,cerficpic = img,cerficpic2 = img2,cerficpic3 = img3,description = description)
    latests.save()
    return render(request,'generate_slip.html')

我的显示图像的模板：

            {% if i.cerficpic %}


            <div class="col-6 col-md-4" style="widh:500;height:500"><img src="{{i.cerficpic.url}}" > </div>
            {% endif %}

我的主要目的是将原始图像存储在单独的路径上，每当用户生成滑动时，它都会从原始图像中获取复制图像并进行一些粘贴并保存到第二条路径， 所以我将能够将两个图像作为原始路径和第二个路径到 html 模板 关于这个问题，我搜索了（谷歌，youtube）两到三周，但没有找到解决方案 如果有人解决了我的问题，我将不胜感激
