Why am I getting internal server error with my python code? - python

I'm experimenting and working on a Flask webpage what's gonna use some data from MySQL database and after a little coding I got internal server error and I don't know why.
After several days I cant work out the problem what can I do for it to work?
I'm using Python3, the server where is hosted is Ubuntu system and I can reach the site via LAN right now with the servers LAN domain (server's name) name that I host via Hyper-V cause I don't have a spare PC for that with Ubuntu on it.
The weird part abut it that when I test it locally on my laptop I wont get the 500 Error only if I want to connect the page what's hosted on the server virtual machine.
Because I don't know where is the problem I uploaded most of the files to GitHub, this gonna be changed of course and later deleted for security reasons but now its easier.

Do not download the module I mistook content_management as pip module. you can uninstall the module pip uninstall contentful_management
The error comes because you are importing module in init.py.
try this:
from name_of_the_parent_directory import content_management
You an try using
from . import content_management
name_of_the_parent_directory - means the parent directory, in your github it will be webpage.

Please help me to resolve the issue. It would be very helpful for me.

Are you sure that azure.storage is installed on the machine?
Please install it before you run your project:
script: pip install azure-storage
Try pip list to see what all modules are installed on your machine.
Also, see that, the version which is used by your code, is installed on your machine.

I followed this article for deploy flask with apache.
https://dev.to/sm0ke/flask-deploy-with-apache-on-centos-minimal-setup-2kb7
and install cx_Oracle and I copied it where I thought I needed it.

|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
But it still gives the error.
Is there any other way?

Ensure that the required Oracle Instant Client is installed to the Apache user by downloading
https://download.oracle.com/otn_software/linux/instantclient/199000/instantclient-basic-linux.x64-19.9.0.0.0dbru.zip
and unzip ut to a folder Apache user owns or is accessible for read and execute - lets say
/apache/oracle
After that, ensure PATH, ORACLE_HOME and LD_LIBRARY_PATH ist set properly as Apache User - i.e.
export ORACLE_HOME=/apache/oracle
export PATH=$PATH:$ORACLE_HOME
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
If you start Apache as service then you may need to set the variables to root or user who starts apache.

Why Apache server throws syntax error with snowflake ingest module in python

I have a flask application running on apache server in the Linux box(ec2 instance), which calls the python script that does the work of moving the files from s3 to snowflake. The script works fine if executed directly. It throws the below error for the snowflake's ingest python module when trying to host it on apache using virtualhost and mod_wsgi. The module is installed in the default site packages.
Apache server version: 2.4.41
Python Version: 3.7
snowflake: snowflake_connector_python-2.1.3-py3.7-nspkg.pth
OS: AMAZON linux 2
 
Below is the apache error log, when i try to restart:

It looks like when you're executing this from mod_wsgi, you're using Python 2 instead of Python 3. The error message you see is happening because Snowflake's simple ingest manager uses type hints (via the typing module), which are not available in Python 2.
Here's a simple fragment that fails with the same error in Python 2 but succeeds in Python 3:
from typing import Text
def foo(bar: Text):
print(bar)
foo('huh')

my goal is not just to solve one error is to be able to import the right way from now on

This is actually the most painful moment for a Flask learner. Basically, your FlaskApp is dependent on FlaskApp.main then FlaskApp.models and then back to FlaskApp which create a perfect case of circular dependency.
Here's the way which I think is elegant and pythonic, by attaching the db variable to app in __init__.py:
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy(app)
app.db = db
with app.app_context():
import FlaskApp.main
In main.py:
from flask import current_app as app
from .models import UserInfo
#app.route('/')
#login_required
def home():
user = app.db.session.query(UserInfo).all()
return render_template('home.html', user=user)
In models.py:
from flask import current_app as app
db = app.db
class UserInfo(db.Model):
__tablename_ = 'user_info'
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True)
email = db.Column(db.String(80), unique=True)
password = db.Column(db.String(100), nullable=False)
posts = relationship('UserPosts', backref='posts')
def __init__(self, username, email, password):
self.username = username
self.email = email
self.password = password
def __repr__(self):
return '{}-{}'.format(self.username, self.email)
Then you can use app.db or current_app.db inside of any functions/methods in your application and don't need to worry about the circular dependency.

got this after using the above answer
RuntimeError: Working outside of application context. This typically means that you attempted to use functionality that needed to interface with the current application object in a way. To solve this set up an application context with app.app_context(). See the documentation for more information.

Configuration file for Flask application

I'm new to Python, so please bear with me.
I am attempting to create a file in which to store my configuration settings in a Flask project. However, I seem to be getting errors when I attempt to import the file.
Here's my configuration file (location: app/config.py):
database_uri = 'something here'
secret_key = something here"
And here's where I'm using it (location: app/models.py):
from app import config
...
app.config['SQLALCHEMY_DATABASE_URI'] = config.database_uri
However, I seem to be getting this error when launching the application:

Your config file should look like this:
SQLALCHEMY_DATABASE_URI = '<your-db-driver>://<user>:<pw>#<db-url>'
SECRET_KEY = '<your-very-secret-key>'
Then you can do:
app = Flask(__name__)
app.config.from_object('config')
