如何添加一个空白页面并使用wagtail(nescode)生成一个菜单？

from wagtail.core.models import Page
from django.db import models

class BlankPage(Page):
    # 添加自定义字段
    title = models.CharField(max_length=255)
    content = models.TextField()

python manage.py makemigrations

python manage.py migrate

from wagtail.admin.rich_text import register_rich_text_features
from wagtail.core.fields import RichTextField

@register_rich_text_features
class BlankPageFeature:
    # 将BlankPage模型类与富文本字段关联
    features = ["blank_page"]

    @classmethod
    def apply_to(cls, model):
        model.content_panels.append("content")

# 将富文本字段注册为"blank_page"特性
register_rich_text_features(["blank_page"])(RichTextField)

python manage.py runserver

python manage.py wagtailmenus_update
