<div class="entry-content"><h3>需求：</h3>
<p>今天写一个model时写了个字段<code>create_by=models.ForeignKey(User)</code>。 <br />
想给它预填入当前的已登录用户。需求类似如下（当然不可能那样写）： <br />
<code>created_by = models.ForeignKey(User, default=request.user)</code><br />
如果以上需求在<code>View</code>里，很好解决的。可现在在AdminModel里，而且在Xadmin环境下。<br />
于是，Google,得<a href="http://stackoverflow.com/questions/937954/how-do-you-specify-a-default-for-a-django-foreignkey-model-or-adminmodel-field">StackOverFlow</a>，找到了<a href="http://www.b-list.org/weblog/2008/dec/24/admin/">参考资料1</a>。感谢Google，感谢StackOverFlowx，感谢<a href="http://www.b-list.org/weblog/2008/dec/24/admin/">参考资料1</a>。<a href="https://github.com/sshwsfc/django-xadmin/issues/96">参考资料2</a></p>
<h3>解决方案</h3>
<h4>在默认的django admin环境下</h4>
<h5><code>models.py</code></h5>
