Django Ckeditor-禁用图像复制粘贴

我在我的模型中使用RichTextUploadField并粘贴google文档中的内容。我已使用forceAsPlainText从内容中删除格式。问题是，当我从文档中复制图像时，源中的URL是google drive的，而不是从我的服务器机器

CKEDITOR_UPLOAD_PATH = "uploads/"
CKEDITOR_IMAGE_BACKEND = "pillow"
CKEDITOR_CONFIGS = {
    "default": {
        "toolbar_DefaultToolbarConfig": [
            {
                "name": "basicstyles",
                "items": [
                    "Bold",
                    "Italic",
                    "Underline",
                    "Strike",
                    "Subscript",
                    "Superscript",
                ],
            },

                "items": ["Paste", "PasteText", "CopyFormatting", "RemoveFormat",],
            },
            {
                "name": "style",
                "items": ["FontSize", "Format", "TextColor", "BGColor",],
            },
            {
                "name": "extra",
                "items": [
                    "Link",

                    "InsertSpecialCharacter",
                ],
            },
            {"name": "replace", "items": ["Find", "Replace", "SelectAll",],},

}

我已经介绍了Ckeditor的解决方案，但大多数解决方案要么完全禁用图像上传/粘贴，要么从工具栏中删除“图像”选项。 我不想那样。我只希望禁用图像复制粘贴，因此当用户使用工具栏中的图像选项上载时，链接将来自服务器机器

CKEDITOR_CONFIGS = {

                ],
            },
            {"name": "replace", "items": ["Find", "Replace", "SelectAll",],},
            {"name": "source", "items": ["Maximize", "Source",],},
        ],
        "title": False,
        "toolbar": "DefaultToolbarConfig",
        "linkShowTargetTab": False,
        "linkShowAdvancedTab": False,
        "height": "250px",
        "width": "auto",
        "forcePasteAsPlainText ": True,
        "pasteDataImages": False,
        "tabSpaces": 4,
        "extraPlugins": ",".join(["codesnippet", "image2", "embed", "tableresize",]),
    }
}

这是我的ckeditor配置设置

谢谢你的帮助
