RichTextField 在 Wagtail 2.0 中无法使用 Draftail 编辑

Question

我将我的网站（开发版）更新为 wagtail 2.0，并且我的页面的所有 RichTextField 属性都完全不可编辑，使用 Draftail.js。我在我的 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，已经保存的内容没有打印出来，也没有编辑功能了。这是模型定义：

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")
]

还有我的 settings.py 文件：

from decouple import config

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

新的 Draftail.js 编辑器看起来像是个问题……

Answer 1

所以，我首先尝试清除缓存，但没有奏效。 然后我记得我习惯设置firefox在它关闭时自动清除缓存，所以我检查了我的firefox设置，它确实是这样设置的。然后，我尝试了@fixgoats 解决方案，我清除了我没有自己创建的静态文件并运行 collectstatic，它没有工作。而且我记得我不应该在开发环境中运行 collectstatic ，所以我删除了它们而没有再次运行 collectstatic ，它没有工作，所以我清除了缓存（因为在此过程中我没有关闭 firefox ）并且它在那里工作。

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 正在使用和缓存这些过时的文件（一个问题隐藏了另一个）。现在，一切正常，非常感谢大家。

我相信我遇到了同样的问题，至少错误消息的标题是相同的，并且描述非常相似。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。
