存在死循环的情况吗？django在保存时会自动进行安全处理，主要就是将非ascii码去掉，然后判断上传目录下是否有同名的文件，如果有，则加上'_'，再判断，直到没有同名的文件。因此如果有死循环，它会一直保存，再保存。

这个是不是你的环境有问啊。traceback是python的标准模块，怎么会导不进去呢？

这句话当第一次上传还不存在这个文件会如何呢？建议你先删除以前的文件，再保存。

会不会是以前测试留下来的。你可以先全部删掉，再试一下，看一看一次会生成多个吗？

Model定义看不出什么，不过一般upload_to是相对于settings.py MEDIA_ROOT的相对路径，不过我想使用绝对路径也不会有问题。

至于save可能要进行调试才知道了看不出什么来。我自已倒是没有遇到过你说的问题，不过我也不使用django的admin，都是自已做，所以处理方式不一样。

问题在这里：
super(Video, self).save()
self.save_videoupload_file('te.mov',content)

save_videoupload_file('te.mov',content) 又会调用self.save的方法，结果递归下去了，没完没了....
要另外保存直接用open,write,close...

Subject: Re: [python-chinese]django 运用save_FOO_file()时出错？


噢，可能不是这个错误引起的。

我是使用的django自带的admin管理系统做的。只是重定义了，save()方法。

models就是这样的:

class Video( models.Model):
    videoupload = models.FileField(upload_to='/home/purpen/video
')
    comment = models.CharField(maxlength=250,blank=True)
    flvfilename = models.CharField(maxlength=250,blank=True,null=True) 
    
    def save(self):
        content = open(self.get_videoupload_filename(), 'rb').read( self.get_videoupload_size())
        super(Video, self).save()
        self.save_videoupload_file('te.mov',content) 

这有什么错误吗？

你有别的方法解决吗？
