Flask 应用程序仍然以 500 结束，Heroku

Question

仍在获取这些日志，但我的 500 页扩展了我的 base.html

2015-01-07T10:21:31.317465+00:00 heroku[router]: at=info method=GET path="/" host=sheltered-ravine-5921.herokuapp.com request_id=60e4b20d-f93a-408c-b8de-282c5efc52ce fwd="193.179.215.98" dyno=web.1 connect=2ms service=95ms status=500 bytes=1493

我的主文件

import os
import psycopg2

from flask import Flask, render_template, send_from_directory
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = os.environ['DATABASE_URL']
db = SQLAlchemy(app)

from views import *

db.drop_all()
db.create_all()

if __name__ == '__main__':
    app.debug = True
    app.run()

和views.py

import os
from flask import Flask, render_template, send_from_directory
from flask import session, request, flash, url_for, redirect, render_template, abort ,g
from flask.ext.login import login_user , logout_user, current_user, login_required
from flask.ext.login import LoginManager
from jdutrunit import app, db
from models import User

login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'

@login_manager.user_loader
def load_user(id):
    return User.query.get(int(id))

@app.route('/')
#@login_required
def index():
    return render_template('index.html')

@app.route('/favicon.ico')
def favicon():
    return send_from_directory(os.path.join(app.root_path, 'static/ico/favicon.ico'))

@app.errorhandler(404)
def page_not_found(e):
    return render_template('404.html'), 404

@app.errorhandler(500)
def internal_error(error):
    db.session.rollback()
    return render_template('500.html'), 500

所以我还是不明白为什么https://sheltered-ravine-5921.herokuapp.com/不能继续index.html

{% extends "base.html" %}
{% block title %} - Home {% endblock %}
{% block content %}
<h2>Ahoooj valecniku</h2>
{% endblock %}

而且我不确定如何从 gunicorn 获得最大的收益，从哪里获得 heroku 的日志

web: gunicorn jdutrunit:app --log-file=- --debug --error-logfile /tmp/gunicornerror --log-level debug

感谢帮助

我明白了，缺少部分：

app.secret_key = 'abrakadabra'

Flask 应用程序仍然以 500 结束，Heroku

Flask app still end on 500, Heroku
