Python 404设置postgres数据库路径的问题

我一直在试图弄清楚我是如何将数据库路径格式化错误的。我尝试了许多不同的方法，但都返回了404

#models.py

import os
from sqlalchemy import Column, String, Integer, create_engine
from flask_sqlalchemy import SQLAlchemy
import json

database_name = "trivia"
database_path = "postgres://{}:{}@{}/{}".format('postgres', 'password', 'localhost:5432', database_name)

db = SQLAlchemy()

def setup_db(app, database_path=database_path):
    app.config["SQLALCHEMY_DATABASE_URI"] = database_path
    app.config["SQLALCHEMY_TRACK_MODIFICATIONS"] = False
    db.app = app
    db.init_app(app)
    db.create_all()

我的数据库设置只是为了表明我已经设置好了，并且我的数据库名称实际上被称为“琐事”：

    $ psql -U postgres
Password for user postgres: 
psql (12.1)
WARNING: Console code page (437) differs from Windows code page (1252)
         8-bit characters might not work correctly. See psql reference
         page "Notes for Windows users" for details.
Type "help" for help.
postgres=# \c trivia
You are now connected to database "trivia" as user "postgres".
trivia=# \dt
           List of relations
 Schema |    Name    | Type  |  Owner
--------+------------+-------+----------
 public | categories | table | postgres
 public | questions  | table | postgres
(2 rows)
trivia=# \d
                List of relations
 Schema |       Name        |   Type   |  Owner
--------+-------------------+----------+----------
 public | categories        | table    | postgres
 public | categories_id_seq | sequence | postgres
 public | questions         | table    | postgres
 public | questions_id_seq  | sequence | postgres
(4 rows)

感谢您的帮助

您凭什么确定数据库连接有问题？如果数据库出现问题，我希望HTTP响应的状态代码为5xx（至少在开发模式下）。状态代码404可能表示在给定的URI中没有端点。@如果您愿意看一看，这里是我的git代表。我认为我的数据库有问题，因为没有任何东西要显示。您触发哪个API调用？
