应用程序/管理员/核心.py公司名称：

class MicroModelView(ModelView):
    page_size = 5

问题是什么，如何解决？在

Answer 1

错误是由您将index_view设置为ModelView子类引起的。别那样做。在

通常，index_view被设置为^{} class的实例，正是这个类注册了一个admin.static视图来处理管理UI中使用的静态文件（模板中使用的Javascript和CSS文件）。在

但是ModelView子类没有提供这些功能。您需要用admin.add_view()调用注册这些调用：

f_admin = Admin(
    app,
    name='new admin',
    template_mode='bootstrap3',
)
f_admin.add_view(MicroModelView(User, db.session, endpoint='users', url='/users'))

如果要更改默认的/admin/页面行为，则需要将AdminIndexView类的子类化并重写其index方法；可以重定向到users视图，例如：
