真是太奇怪了，因为在另一个模板它的工作原理没有错误。

你能帮我吗？谢谢。

你是否将视图中的变量'avatar'传递给模板？ – 2011-05-12 02:29:59

@Alex Jillard什么应该是可变'头像'？ – 2011-05-12 15:14:57

从django-avatar docs：

{% render_avatar avatar [size in pixels] %}

鉴于实际avatar.models.Avatar对象实例，生成一个HTML img标签代表的要求大小的头像。

所以，在你看来，你需要获得与用户相关联的化身： avatar = Avatar.objects.get(user=request.user）

然后就是变量传递到模板。

如何导入头像模型？ avatar.models.Avatar不起作用。 – 2011-05-12 16:03:31

我已将所有头像目录复制到我的项目，现在我可以导入头像。问题是.get不起作用，因为'MultipleObjectsReturned：get（）返回多个头像 - 它返回3'我该如何修复？ – 2011-05-12 16:07:51

您可以使用.filter（）而不是.get（），但您需要确定应使用哪个返回的头像。 – 2011-05-12 16:20:16
