不同图片相同名字后者图片存储会覆盖前者解决办法

使用uuid唯一标识码

    #文件上传1：写到服务器中
    file_hpic = request.FILES['hpic']
    file_name = mytools.do_file_name(file_hpic.name)
    file_path = os.path.join(settings.MEDIA_ROOT,'book/images',file_name)
    with open(file_path,'wb') as file:
        for chunk in file_hpic.chunks():
            file.write(chunk)

    #文件上传2：写入到数据库中
    heroinfo.hpic = os.path.join('book/images',file_name)


#mytools.py文件下的
def do_file_name(file_name):
    return str(uuid.uuid1()) + os.path.splitext(file_name)[1]
