删除 {{form.media}} 上面的脚本标签不会引发任何与 jquery 相关的错误，但它会丢失小部件功能。我需要那个脚本标签，但我不希望 Jquery 返回 $ 不是一个函数。我尝试添加 $.noconflict、jQuery(document).ready 但没有任何效果。

最佳答案
我很确定你的整个问题是你的 RelatedObjectsLookups.js JS 文件的末尾说 django.jQuery，它不存在(或在至少，您正在加载的 googleapis jQuery 文件不会定义它)。将其更改为 window.jQuery，一切都应该适合您。
根据您的回复进行编辑
既然你不能改变说 django.jQuery 的行，那么让我们定义它。
在包含 jQuery 文件后，立即添加以下标记。
<script>
django = django || {};
django.jQuery = django.jQuery || jQuery;
</script>
如果尚未设置，这会将 django.jQuery 设置为 jQuery(包含在您的 googleapis 文件中)。现在它将存在供您以后的脚本使用。
