this is my modules and folder layout i have a import problem in init i have db = sqlalchemy im trying to import db to views.py, models.py and db_create.py but im getting all kinds of importing errors because im not importing thr proper way now my question is if i want to import db to the modules i specified how would i do it without getting a error
some of the code importing db
models.py
from FlaskApp import 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)
views.py
from FlaskApp import db
#app.route('/')
#login_required
def home():
user = db.session.query(UserInfo).all()
return render_template('home.html', user=user)
__init__.py
from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy(app)

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.

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

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.

FileNotFoundError on Python Flask app hosted on Ubuntu-Apache with WSGI-Mod

I have a python flask app hosted on ubuntu-apache with WSGI-mod. It works perfectly on my local windows machine, but on the ubuntu machine I cannot seem to access './static/images/' through my python script? Everything else works, but this exact piece of code does not for some reason and produces this error.
I've tried searching around and editing the VirtualHost, but nothing seems to work. Can't wrap my head around the problem. Any ideas?
Code that gives error:
if session.get('logged_in'):
directory = r'./static/images/'
urls = []
for filename in os.listdir(directory):
if filename.endswith(".jpg") or filename.endswith(".png") or filename.endswith(".jpeg"):
urls.append(os.path.join(directory, filename))
else:
continue

Figured it out. When stating directory-paths in python, the "." does not mean relative to current file, but relative to current working directory which can be changed with os.chdir('path/to/dir')

ImproperlyConfigured: The SECRET_KEY setting must not be empty in Apache and wsgi_mod

I'm trying to deploy Django project on Apache and wsgi_mod in Windows 10. What I did so far:
1. Added following in httpd.conf of Apache conf folder
WSGIScriptAlias / "C:/Bitnami/djangostack-1.10.1-0/apps/django/django_projects/project/egeirn/wsgi.py"
WSGIPythonPath "C:/Bitnami/djangostack-1.10.1-0/apps/django/django_projects/project;C:/Bitnami/djangostack-1.10.1-0/python/Lib/site-packages"
<Directory "C:/Bitnami/djangostack-1.10.1-0/apps/django/django_projects/project/egeirn">
<Files wsgi.py>
Require all granted
</Files>
</Directory>
2. Following is the content of my wsgi.py file:
import os
import sys
from django.core.wsgi import get_wsgi_application
sys.path.append('C:/Bitnami/djangostack-1.10.1-0/apps/django/django_projects/project')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "egeirn.settings")
application = get_wsgi_application()
When I start the Apache server, it gives the following error in logs file:

I am using django-environ to read .env file and keep configurations in environment variables. Although I have my SECRET_KEY in the base.py file
I have used it like this in base.py file:
import environ
# three folder back (/project/egeirn/settings/ - 3 = /)
root = environ.Path(__file__) - 3
# set default values and casting
env = environ.Env(DEBUG=(bool, False),)
# reading .env file
environ.Env.read_env(os.path.join(BASE_DIR, '../../config/.env'))
SITE_ROOT = root()
# Raises ImproperlyConfigured exception if SECRET_KEY not in os.environ
SECRET_KEY = env('SECRET_KEY')
This is my .env file:
SECRET_KEY=<MY_SECRET_KEY_HERE>
Please tell me what I am doing wrong here, how come it cannot read the SECRET_KEY?
Thanks

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')

How to set environ variables in local development with virtualenv

I am currently trying to publish via ZIP my django app to an AWS elasticbeanstalk.
As I have a local and online development enviroment I would like to make use of the environ variables, that are used anyways by AWS.
For my development environments I am already using virtualenv. Apache runs with wsgi enabled and is supposed to use such environments. Unfortunately, it does not know the environ that I have set in the bin/activate.
Django throws a 500 error, since it cannot connect to the database as it does not have access to the environ vars:
1:53.862779 2015] [wsgi:error] [pid 20639] [remote 127.0.0.1:51896] KeyError: 'RDS_DB_NAME'
If I activate my env and look into the env vars:
(myenv)[bs#debian-gohan:]/var/www/vhosts/mysite $ env | grep RDS
RDS_HOSTNAME=localhost
... and I get the others as well...
My Apache Vhost is:
<VirtualHost *:80>
WSGIDaemonProcess mysite python-path=/home/bs/envs/myenv/bin/python2.7:/home/bs/envs/myenv/lib/python2.7/site-packages
WSGIProcessGroup mysite
WSGIScriptAlias / /var/www/vhosts/main-page/mysite/wsgi.py
Does anyone have an idea why the environ vars are not seen by the apache ?
EDIT 1:
I have tried to use SetEnv in the Apache config, like this:
SetEnv RDS_HOSTNAME "localhost"
Unfortunately, this did not work. I then removed the ProcessGroup and only used a simple WSGIPythonPath. That did not work either.
The error in the apache log remains the same:
