xml - Odoo 路由给出 "Internal Server Error"错误页面

Question

我正在通过在 Youtube 视频中创建一个新的自定义模块来在 Ubuntu 上学习 Odoo 11 python 开发，其代码可在 github 上找到。

我复制了同一个项目( https://github.com/mtsoftware2016/Odoo-First-Model )，除了路线外一切正常。

Controller .py:

from odoo import http

class MyfirstModel(http.Controller):
    @http.route('/home', auth='public')
    def home(self, **kw):
        return 'Hello world'

    @http.route('/example', type='http', auth='public', website=True)
    def render_example_page(self):
        customer = http.request.env['customer'].sudo().search([])
        return http.request.render('myfirst_model.example_page', {'customers': customer})

这里/home 路由是有效的，但是/example 在页面上给出了这个错误消息:

内部服务器错误

服务器遇到内部错误，无法完成您的请求。服务器过载或应用程序出错。
