Question

我将我的网站（开发版本）更新为wagtail 2.0，我的网页的所有RichTextField属性都完全无法编辑，使用Draftail.js。我在settings.py中添加了以下几行：

WAGTAILADMIN_RICH_TEXT_EDITORS = {
    'default': {
        'WIDGET': 'wagtail.admin.rich_text.HalloRichTextArea'
    }
}

恢复到以前的Hallo.js编辑器，它可以正常工作。但是当我删除它时，已经保存的内容不会被打印，并且不再有编辑功能。以下是模型定义：

from django.db import models

from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel

class BlogIndexPage(Page):
    intro = RichTextField(blank=True,features=[
        'h2',
        'h3',
        'ol',
        'ul',
        'bold',
        'italic',
        'link'
    ])

content_panels = Page.content_panels + [
    FieldPanel('intro', classname="full")
]

我的settings.py文件：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

看起来像是一个问题，使用新的Draftail.js编辑器......

Answer 1

所以，首先我尝试清除缓存，但是没有用。然后我记得我习惯设置firefox自动清除缓存，当它关闭时，所以我检查了我的firefox设置，它确实设置为这样。然后，我尝试了@fixgoats解决方案，我清除了我自己没有创建的静态文件并运行collectstatic，它没有用。我记得我不应该在开发环境中运行collectstatic，所以我删除它们而不再运行collectstatic，它不起作用，所以我清除了缓存（因为我没有关闭firefox在这个过程中）并且它有效。

我的猜测是，我将过时的静态文件直接存储在dev静态目录中，而firefox正在使用并缓存那些过时的文件（隐藏另一个的一个问题）。现在，一切正常，非常感谢你们所有人。

Answer 2

我相信我遇到了同样的问题，至少错误信息的标题是相同的，描述非常相似。对我有用的是删除静态wagtailadmin javascript目录并再次运行collectstatic。虽然我仍然不知道究竟是什么导致了这个错误。
