Question

我的头部因为撞墙而受伤...为什么内容面板无法识别我的DetailPage中的字段？一切正常，直到我将FieldPanel添加到content_panels。

哦，这也是使用2.0版本的wagtail。这似乎与字段类型无关，事件是一个简单的CharBlock触发此错误。

django.core.exceptions.FieldDoesNotExist: DetailPage has no field named 'links'

models.py 来自django.db导入模型

from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.core import blocks
from wagtail.core.blocks import ListBlock, URLBlock, StructBlock, TextBlock, CharBlock
from wagtail.admin.edit_handlers import FieldPanel
from wagtail.search import index


class DetailPage(Page):
    """
    Two column detail page with quick links on the left
    """
    links = blocks.ListBlock(blocks.URLBlock(), null=True, blank=True)
    body = RichTextField(blank=True)

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

Answer 1

ListBlock和其他块类型（例如CharBlock）不能与Django's model fields互换 - 它们不能直接在页面模型定义中使用，只能在StreamField中使用。

将content_esnels字段添加到Page时FieldDoesNotExist
