如何在get_absolute_url中包含其他应用的urls.py : reverse() django？

from django.urls import include, path
from app1 import urls as app1_urls
from app2 import urls as app2_urls

urlpatterns = [
    path('app1/', include(app1_urls)),
    path('app2/', include(app2_urls)),
]

from django.urls import path
from . import views

app_name = 'app1'
urlpatterns = [
    path('example/', views.example_view, name='example'),
    # 其他URL路由
]

from django.urls import reverse
from django.db import models

class MyModel(models.Model):
    # 模型字段定义

    def get_absolute_url(self):
        return reverse('app1:example')
