I'm trying to build a blog as a portfolio sample using python3 and flask and flask_jwt_extended.
I can create a single file like this and it will run:
from flask_jwt_extended import (create_access_token, get_jwt_identity, JWTManager, jwt_required, get_raw_jwt)
from flask import Flask, request, Blueprint
app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'this-is-super-secret'
app.config['JWT_BLACKLIST_ENABLED'] = True
app.config['JWT_BLACKLIST_TOKEN_CHECKS'] = ['access']
jwt = JWTManager(app)
#app.route(....)
#jwt required
But when I try to use Blueprint, it will not register the JWTManager
Here is my user.py file:
from flask_jwt_extended import (create_access_token, get_jwt_identity, JWTManager, jwt_required, get_raw_jwt)
from flask import Flask, request, Blueprint
app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'this-is-super-secret'
app.config['JWT_BLACKLIST_ENABLED'] = True
app.config['JWT_BLACKLIST_TOKEN_CHECKS'] = ['access']
jwt = JWTManager(app)
user_blueprint = Blueprint('user_blueprint', __name__)
#user_blueprint.route(....)
#jwt required
here is my app.py:
from user import *
app = Flask(__name__)
app.register_blueprint(user_blueprint)
Now when I try to run app.py, this it returns a 500 (Internal Error) and will log this to the log file:
Traceback (most recent call last):
File "/usr/local/lib/python3.6/dist-packages/flask_jwt_extended/utils.py", line 127, in _get_jwt_manager

During handling of the above exception, another exception occurred:

Could someone please tell me what to do? I tried EVERYTHING for the last 3 days. its been 20 hours of debugging and it's still not fixed
You need to use the same app in every location. Currently you are creating an app in your users.py file, and a different app in you app.py file.
Generally you will want to use the flask application factory pattern to do this (https://flask.palletsprojects.com/en/1.1.x/patterns/appfactories/). An example might look something like this:
extensions.py
from flask_jwt_extended import JWTManager
jwt = JWTManager()
users.py
from flask_jwt_extended import (create_access_token, get_jwt_identity, jwt_required, get_raw_jwt)
from flask import Flask, request, Blueprint
user_blueprint = Blueprint('user_blueprint', __name__)
#user_blueprint.route(....)
#jwt_required
app.py
from extensions import jwt
from users import users_blueprint
def create_app():
app = Flask(__name__)
app.secret_key = 'ChangeMe!'
app.config['JWT_BLACKLIST_ENABLED'] = True
app.config['JWT_BLACKLIST_TOKEN_CHECKS'] = ['access']
jwt.init_app(app)
app.register_blueprint(user_blueprint)
return app
main.py
from app import create_app
app = create_app()
if __name__ == '__main__':
app.run()

I am using waitress on IIS with Flask.
I have a route that sets a session as follows
#gp_clinicals_bp.route("/setting", methods=["POST","GET"])
def gp_clinicals():
session["gp_clinicals_meds_repeat"] = "123456"
return session["gp_clinicals_meds_repeat"]
This returns, unsurprisingly:
123456
I have another route as follows:
#gp_clinicals_bp.route("/testing", methods=["POST","GET"])
def gp_clinicals_test():
return session["gp_clinicals_meds_repeat"]
Now, I get nothing back and the following in the error log

The site in IIS is running through a reverse proxy in IIS - could that be doing it?
I have been really stumped on this, been out of this game of web dev/python for a bit. I had a previously working Azure app service running this website, we did a minor HTML spelling change and re deployed. I am assuming some dependency got updated and now its broken. I don't know if this is a packaging version issue or if I have a missing import for my flask app.
I am getting a NameError: name 'Markup' is not defined error when trying to load a static html page. My app starts up just fine but I can't load the actual web pages.

Flask-ReCaptcha is a very old project. The last update of Flask-ReCaptcha is on 2016. You'd better not use it.
Back to the error log itself, Flask-ReCaptcha has code like from jinja2 import Markup. But, since jinja2==3.1.0, Markup's position has changed. Try pip install jinja2==3.0.0`.
You will probably meet other problems as Flask-ReCaptcha is really old.
Go to Python installation folder
Go to Lib > site-packages
Open flask_recaptcha.py
You'll see something like this:
try:
from flask import request
from jinja2 import Markup
import requests
except ImportError as ex:
print("Missing dependencies")
Change it to:
try:
from flask import request
from markupsafe import Markup
import requests
except ImportError as ex:
print("Missing dependencies")

I am running Windows and used the following command
set FLASK_APP=project
I then use
flask run
Thank you in advance for the help.
You can try to search same problem
UndefinedError: 'current_user' is undefined
Check the init file:
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):
user = User.query.filter_by(id=user_id).first()
And strure, i think you should do like that
I have a simple flash website created and deployed in a server with Nginx as frontend and gunicorn as backend to run the python code. With this setup everything is working fine. However, if i run the server using supervisor module, I'm getting below error. I have ensured all the environment variables are accessible, they are placed in .bashrc under home directory.
Not sure what am missing. My python code is deployed in server inside a pipenv virtual environment. supervisor was started within the virtualenv only. Not sure if it has any relevance.

Can you post your supervisor config file? My guess here is that it's related to your PATH definition...
EDIT (12/Nov): After seeing you're supervisor config file I noticed that you haven't set the environment path.
A list of key/value pairs in the form KEY="val",KEY2="val2" that will be placed in the supervisord process’ environment (and as a result in all of its child process’ environments)
from: https://docs.red-dove.com/supervisor/configuration.html
Can you try adding this to your configuration file? This will define your PATH as "/usr/bin/" for the environment that runs your gunicorn. If that doesn't work, please try use the path from where your virtualenv is running.
environment=PATH="/usr/bin"
I understand that Pandas isn't included and believe that I've properly included the library via adding the module into the lib directory for the app and by adding
from google.appengine.ext import vendor
vendor.add('lib')
to appengine_config.py - other modules don't seem to be having issues.
When I run my app, the following stack trace shows up:

AttributeError: 'module' object has no attribute 'read_sql'**
Here's my code:
from flask import Flask, request, render_template
import pandas
from sqlalchemy import create_engine
import pymysql
import random
app = Flask(__name__)
#app.route('/')
def index():
con = create_engine('mysql+pymysql://user:pass#ix.cs.uoregon.edu:port/fpl', echo=False)
datar = pandas.read_sql('SELECT p.nationality, SUM(s.mins_played) AS mins_played FROM CurrentSeasonStats s left join Player p ON s.Player_pid = p.pid GROUP BY p.nationality', con)
return render_template('index.html', table=datar)
if __name__ == '__main__':
app.run()
Any ideas?
I had copy-pasted a Binary Skeleton version of the pandas library into /lib/ which is why none of the pandas functions were working.
This a direct and annoying result of me not using virtual environments...
USE VIRTUAL ENVIRONMENTS, KIDS!
