Problems running Flask Web App on linux Debian using Gunicorn and Nginx

Question

So I'm currently trying to put my Web App online using Flask, Debian 9, Gunicorn. The problem I'm having, after typing > gunicorn wsgi:app:

[2019-11-15 12:22:11 +0000] [11643] [ERROR] Exception in worker process

My wsgi.py:

from __init__ import app

if __name__ == "__main__":
    app.run()

My init .py:

# init.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager 
from flask_bootstrap import Bootstrap

db = SQLAlchemy()

def create_app():
    app = Flask(__name__)
    Bootstrap(app)

    app.config['SECRET_KEY'] = 'secretkey'
    app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///db.sqlite'

    db.init_app(app)

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

    from .models import User

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

    from .auth import auth as auth_blueprint
    app.register_blueprint(auth_blueprint)

    from .main import main as main_blueprint
    app.register_blueprint(main_blueprint)

    if __name__ == '__name__':
        app.run()

    return app

create_app()

My models.py:

models.py

from flask_login import UserMixin
from . import db

class User(UserMixin, db.Model):
    id = db.Column(db.Integer, primary_key=True) # primary keys are required by SQLAlchemy
    email = db.Column(db.String(100), unique=True)
    password = db.Column(db.String(100))
    name = db.Column(db.String(1000))

Note: All indepencies are installed in my virtualenv, I've tried using gunicorn with only this code:

from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
    return "Hello World!"
if __name__ == '__main__':
    app.run(debug=True,host='0.0.0.0')

And that worked perfectly fine.

Answer 1

I changed every import that had a. and changed the init to app , deleted the create_app function.
