Wagtail:如何在models.py中访问页面类中的“request”

'context_processors': [
    # 其他的context processors
    'wagtail.contrib.settings.context_processors.settings',
    'yourapp.context_processors.wagtail_request',
],

from django.utils.functional import SimpleLazyObject
from wagtail.core.models import Page

def get_request():
    # 通过Wagtail的Page类获取当前请求的页面对象
    return SimpleLazyObject(lambda: Page.objects.get(id=request.wagtail.page.id))

def wagtail_request(request):
    # 将页面对象的request属性设置为当前请求
    get_request.request = request
    return {'wagtail_request': get_request}

from django.db import models
from yourapp.context_processors import wagtail_request

class YourModel(models.Model):
    def your_method(self):
        request = wagtail_request.request
        # 在这里可以使用request对象进行相关操作
