Django，django-ckeditor，Google MDL：无法读取未定义的属性“ getSelection”

Question

我正在将Django 1.11和django-ckeditor用于admin面板中的文本字段，以及admin之外的某些输入（以公共形式）。 作为CSS框架-Google Material Design Lite。

当我尝试将ckeditor集成到公共形式时， charfield与ckeditor完全不起作用。 好像我无法专注于此字段，当我单击任何ckeditor control元素时，我都会出错

Uncaught TypeError: Cannot read property 'getSelection' of undefined

    at CKEDITOR.dom.selection (ckeditor.js:443)

在Firefox中：

ckeditor.js 445行：

x?this.document.$.selection:this.document.getWindow().$.getSelection()},getType:x?function(){var a=this._.cache;if(a.type)return a.type;var b=CKEDITOR.SELECTION_NONE;try{var c=this.getNative(),d=c.type;"Text"==d&&(b=CKEDITOR.SELECTION_TEXT);"Control"==d&&(b=CKEDITOR.SELECTION_ELEMENT);c.createRange().parentElement()&&(b=CKEDITOR.SELECTION_TEXT)}catch(e){}return a.type=b}:function(){var a=this._.cache;if(a.type)return a.type;var b=CKEDITOR.SELECTION_TEXT,c=this.getNative();if(!c||!c.rangeCount)b=CKEDITOR.SELECTION_NONE;

Forms.py：

from ckeditor_uploader.widgets import CKEditorUploadingWidget


class PaymentForm(forms.Form):
    comments = forms.CharField(widget=CKEditorUploadingWidget())

为了集成ckeditor js脚本，我在模板中使用{{ form.media }} 。

首先，我尝试搜索有关此错误和任何已知修复程序的信息，但所有founded都不适合我。 我在这里也发现了与ckeditor类似的问题，但没有任何可行的解决方案。

当我检查所有js脚本时，我发现Google Material design lite css框架的Javascript中存在该问题https://github.com/google/material-design-lite

当material.min.js集成到页面脚本中时-ckeditor不起作用。 未缩小的框架js： https://code.getmdl.io/1.3.0/material.js : https://code.getmdl.io/1.3.0/material.js

PS：这是我在这里提出的第一个问题，不便之处，敬请原谅。

谢谢你的帮助！

进行了一些更改，以使django-ckeditor与Google Material Design Lite框架配合使用。 如果需要，您可以使用此版本的django-ckeditor（我的叉子）： https : //github.com/wardal/django-ckeditor，而我们在这里等待官方答复和解决方案： https : //github.com/django-ckeditor / django-ckeditor / issues / 429
