I am trying to setup an Elo rating system for my local 8 ball pool league using:
https://github.com/elovation/elovation
The only changes I have made to above repo prior to deployment are specifying heroku:stack-18 in app.json and running bundle install after specifying to use https:// instead of git://
I have deployed my app to Heroku without error but when loading my app I get a "We're sorry, something went wrong page"
After deployment I have ran heroku run rake db:migrate and heroku restart but my error persists
I have included below output of heroku logs ; any help with the below errors would be greatly appreciated as I am not particularly familiar with Ruby or Heroku postgres.

I'm basically trying to deploy the example in the CherryPy tutorial to Heroku (https://docs.cherrypy.org/en/latest/tutorials.html#tutorial-8-make-it-smoother-with-ajax). When I run the code locally, everything works fine. After deployment to Heroku, I get several error messages:

My Procfile simply contains
web: python app.py
My guess is that the problem has something to do with the little css-trick that avoids refreshing the page in order display the result of a request. But, as you can see, I'm totally new to deployment and this is also my first question on stackoverflow--so my apologies in advance in case I'm missing something obvious here. Any help is much appreciated!
I have an SQLAlchemy database running on a flask app that works fine locally, but as soon as I run it on Heroku I get a strange issue (See stack trace below).
I don't have a model called 'user' so I don't know what's going on. I've made sure that I've run db.create_all().
Creating a row in my table works fine, but it's only once I try selecting some rows do I get an issue (__init__.py):
#app.route('/blog')
def blog():
title = 'Blog'
name = get_name()
blog_text = []
for post in sorted(Post.query.filter_by(category=Post.Category.blog),
key=lambda p: p.posted_at, reverse=True):
content = post.content
blog_text.append(content)
content = '\n'.join(blog_text)
return render_template('blog.html', **locals())
And my 'Post' logic in my models.py:
class Post(db.Model):
__tablename__ = 'user'
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(200), nullable=False)
posted_at = db.Column(db.DateTime, nullable=False, default=datetime.now())
content = db.Column(db.String(200), nullable=False)
content_type = db.Column(db.String(200), default="md", nullable=False) # md / html
category = db.Column(db.String(200), nullable=False, default="blog") # poetry / blog
class Type:
md = "md"
html = "html"
class Category:
poetry = "poetry"
blog = "blog"
...
Here's the error:

You missed that your table is named user in your model:
class Post(db.Model):
__tablename__ = 'user'
# ^^^^^^
The reason it doesn't exist is because Heroku doesn't keep your filesystem changes. You are using a SQLite database:
... app[web.1]: sqlite3.OperationalError: no such table: user
# ^^^^^^^
but a sqlite database is stored on the filesystem of your Heroku dyno. Heroku cleans up (cycles) dynos all the time and spins up a new dyno for you for new requests. From their documentation on how Heroku works:
Changes to the filesystem on one dyno are not propagated to other dynos and are not persisted across deploys and dyno restarts. A better and more scalable approach is to use a shared resource such as a database or queue.
Each time a new dyno is spun up to handle your requests, you'll have a new, clean filesystem without your sqlite database, and so an empty database is created again without any tables in it.
Bottom line: You can't use sqlite on Heroku.
Use a Postgres database instead, see the Heroku Postgres documentation. Don't worry, there is a free tier you can use. When you provision the database as an add-on, the DATABASE_URL config var is set for you, which you can read from your app environment.
I usually configure Flask apps that are designed to run on Heroku to read the environment variable but to fall back to a SQLite database when the environment variable is not set:
import os
from pathlib import Path
_project_root = Path(__file__).resolve().parent.parent
_default_sqlite_db = _project_root / "database.db"
SQLALCHEMY_DATABASE_URI = os.environ.get(
"DATABASE_URL", f"sqlite:///{_default_sqlite_db}"
)
This makes it easy to develop the app locally on SQLite, or set up a local Postgres database for integration testing, and then deploy to Heroku for staging or production.
This question has been asked a lot, but still, nothing seems to be working. My application runs perfectly in testing, but when run on heroku, I get the error 500 saying "we're sorry , but something went wrong." I've checked the log files for the server, and my error seems to be here somewhere:

PostgreSQL (on Heroku) requires you to GROUP BY all the columns in the SELECT list so in this case instead of:
SELECT "movies".* FROM "movies" GROUP BY rating
you might want to do something like:
SELECT rating FROM "movies" GROUP BY rating
or in Rails:
Movie.select(:rating).group(:rating)
We're facing an interesting problem on our staging server on Heroku. Each post/put/delete request freezes for about 10 secondes or more and some of them eventually time out resulting in a Heroku H-12 time out error.
Another interesting detail: the request seems to be processed after the time out because the database records get updated. We do not process a big data, we're just trying to update one field on one record in the DB.
Our local environment (localhost:3000) is working properly. We do not have any blocking action (sending email, processing big queries, ...)
We've tried activating/deactivating caching (dalli), asset compilation, we've switched the instance of our staging server. We've tried different settings in our staging.rb.
Any suggestions on how we could try to troubleshoot this?

Turned out that our staging server didn't include all the Heroku add-ons the live server has.
One of the add-on missing was Flying Sphinx. Some of our models assume Sphinx was there and would try to use it causing that behavior.
