Зарегистрированный URL не найден

Question

Мы реализовали бэкэнд «два в одном» с Flask. Для самого сайта (который мы называем tekid) у нас нет проблем. Но для портала управления (который мы называем tekid-admin), даже при использовании одних и тех же реестров представления, сервер WSGI (dev и prod) возвращает 404 NOT FOUND для всех запросов.

Связанные коды

Записи CLI зарегистрированы как

• tekid -> tekid.cli.www:cli
• tekid-admin -> tekid.cli.adm:cli

Ниже приведен код, который мы использовали для хранения объекта приложения Flask:

# -*- coding: utf-8 -*-
"""Module entrypoint of TekID website."""

# in `tekid/app/www.py` for `tekid`
from tekid.urls.www import app
# in `tekid/app/adm.py` for `tekid-admin`
from tekid.urls.adm import app

Ниже приведен код, который мы использовали для ввода CLI:

# -*- coding: utf-8 -*-
"""CLI for TekID website."""

import click
import flask

import tekid.core.typing as typing
# in `tekid/cli/www.py` for `tekid`
from tekid.app.www import app
# in `tekid/cli/adm.py` for `tekid-admin`
from tekid.app.adm import app

__all__ = ['cli']


@click.group(cls=flask.cli.FlaskGroup, create_app=lambda: app)
def cli() -> typing.NoneType:
    """Management script for the TekID website."""

Ниже приведен кодмы использовали для маршрутизации реестра (мы используем механизм централизованной регистрации, предложенный самим Flask):

# tekid/urls/www.py & tekid/urls/adm.py (same when testing)
# -*- coding: utf-8 -*-
"""URL routing for TekID website."""
# pylint: disable=wrong-import-position

from tekid.core.macro import FLASK as app

__all__ = ['app']

###############################################################################
# load HTML pages

from tekid.urls.pages import *  # pylint: disable=unused-wildcard-import

# index.html
app.add_url_rule('/', view_func=load_index)
... # same routing registry codes

Ожидаемое поведение

NB: tekid и tekid-adminдолжен выдать тот же вывод

Команда routes выдаст примерно так:

$ tekid routes
# or
$ tekid-admin routes
Endpoint        Methods            Rule
--------------  -----------------  -----------------------------------
load_contact    GET, POST          /contact/
load_expertise  GET                /expertise/
load_index      GET                /
load_news       GET, POST          /news/
...
static          GET                /static/<path:filename>

Мы попробуем curl http://127.0.0.1:5000/ после run на сайте (tekid):

$ tekid run

Фактическое поведение

С теми же настройками, что и выше, мы пробуем curl http://127.0.0.1:5000/ после run на портале управления (tekid-admin):

$ tekid-admin run
 * Environment: development
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
