Index page contains data only on first visit; refresh and subsequent visits are empty

Hello all and thanks for taking time to read into this issue I'm having.

I have a small web app that is passing an object to my index page, the index page loops and renders the object into a nice pretty table.

Here is my route:

@app.route('/', methods=['GET'])
def index():
return render_template('index.html', cursor=cursor, current_time=datetime.utcnow())

the "cursor" object is really a mongodb query that was created just above the route descriptor:

cursor = db.ipv4.find().sort([("prefix", 1), ("prefixLen", -1)])

This is ran through the index.html page's template, which looks like this:

{% for route in cursor %}
<tr>
<td>{{ route.prefix }}</td>
<td>{{ route.prefixLen }}</td>
<td>{{ route.aspath }}</td>
</tr>
{% endfor %}

The result is a beautiful table of my previous IPv4 unicast table, and it renders great, but only once! Any second visitor or a refresh to the page shows that there are no rows rendered for my table (looking at the page's source).

My theory is that there is something that I'm missing when passing the cursor variable into the view function, something that currently limits it to run just once. I am new to Flask so it is likely that I am mistaken and would greatly appreciate any pointers.

Running Flask in background (Without Celery)

I am attempting to do some automation work in the background of my Flask application. Basically I get a request and then want to run some boto3 automation infrastructure. Due to the nature of the tasks needing to be synchronous, the connection times out before it can give a response back. I want to simply run this in the background and celery is definitely overkill for this solution. I see that I can use APScheduler and can simply do a one time run based on time. I am wondering I can also do it via multiprocessing. So can I do something like:

@app.route(‘/create’, methods=[‘POST’]
def handle_create_request():
data = some_handler(request)
p=Process(target=create_aws_resources, args=(data,))
p.start()
return “Your resources are being provisioned”

This works locally in my dev, but when running in server implementation, the nature of a WSGI will cause it to be a blocking process. Can anyone give any guidance?

And I feel celery is completely overkill here is due to this process not being run that frequently. It ultimately takes just over a minute to execute and for the most part, it isn’t running that frequently. I know this could be transformed into a microservice down the line, but I am currently looking for a quick solution at the moment.

How to access Google Drive files from a Jupyter server?

I'm working on a project that involves consolidating 100+ .csv files into one file and running specific queries on this data. However, all of these .csv files are located in Google Drive. I don't want to manually download all 100 .csv files and upload them to my Jupyter server, so I'm wondering if there is a way to access them easily and store them in a folder in the server.

I'm aware of the github code that allows you do to this, but my access was denied, so I'm hoping there's another way to do this.

Collaborating on a project.

Hello! I'm looking to create a project and I wanted to see if anyone else is interested in joining. I've gone through a couple books so I'd consider myself a step above beginner in terms of ability and this project wouldn't be anything serious, just an exercise to get better at Django.

[AF] POST request on one of multiple defined endpoints returns 404

EDIT: The error ended up being with NGINX, all I needed to do was change the ownership of the /var/lib/nginx directory from the nginx user to the user running the Flask application. Doh

Hi, I was having the darndest time debugging this and couldn't find anything similar online so hopefully you guys can help me get to the bottom of this

I have two endpoints, a login and a post submitter. Both are GET and POST request endpoints, both are defined, both work locally. Deployed, however, the login endpoint works fine but POST requests on the post submitter endpoint always return a 404. I don't believe it's an issue with NGINX or gunicorn as the logs show nothing out of the ordinary and the login endpoint works flawlessly. I've spent almost two days debugging this and I just can't for the life of me figure it out. Relevant code snippets are posted below.

@app.route('/newpost', methods=['GET', 'POST'])
@login_required
def new_post():
form = BlogForm()
#No code in this conditional is ever actually executed, 404's first
if form.validate_on_submit():
#Omitted code for getting form data and creating form object
try:
#Omitted code for database actions
return redirect(url_for('index', _external=True))
except IntegrityError:
flash("Error inserting into database")
return('', 203)
else:
#Omitted some code for template rendering
return render_template('new_post.html')


@app.route('/login', methods=['GET', 'POST'])
def login():
form = LoginForm()
userAuth = current_user.is_authenticated
if form.validate_on_submit():
flash("Login attempt logged")
user = User.query.filter_by(username=form.userID.data).first()
if user:
checkPass = form.password.data.encode('utf-8')

if bcrypt.checkpw(checkPass, user.password):
user.authenticated = True
login_user(user, remember=form.remember_me.data)
return redirect(url_for('index', _external=True))
else:
form.errors['password'] = 'false'
else:
form.errors['username'] = 'false'

else:
return render_template('login.html',
title='Log In',
loggedIn=userAuth,
form=form)

Python script as Windows service only working in DEBUG mode

Hi r/python, I'm trying to run a dummy Python script as a service in Windows 7. It just writes the current time to a file in disk. My code goes like this:

import os
import time

import win32serviceutil
import win32service
import win32event
import servicemanager
import socket


class AppServerSvc (win32serviceutil.ServiceFramework):
_svc_name_ = "DummyService"
_svc_display_name_ = "Dummy App"

def __init__(self, args):
win32serviceutil.ServiceFramework.__init__(self, args)
self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
socket.setdefaulttimeout(60)

def SvcStop(self):
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
win32event.SetEvent(self.hWaitStop)

def SvcDoRun(self):
self.ReportServiceStatus(win32service.SERVICE_START_PENDING)
self.ReportServiceStatus(win32service.SERVICE_RUNNING)
servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
servicemanager.PYS_SERVICE_STARTED,
(self._svc_name_, ''))
self._logger.info("Service Is Starting")
dummy()


def dummy():
while True:
dummy_file = open('C:\dummy_text.txt', 'w+')
trace = str(time.time()) + '\n'
dummy_file.write(trace)
dummy_file.close()
time.sleep(40)

if __name__ == '__main__':
win32serviceutil.HandleCommandLine(AppServerSvc)

When I go to the directory containing the script and run *python dummyproc.py install* it tells me *Service installed*. I can debug the process with *python dummyproc.py debug* and it works fine (writes the file). But if I run *python dummyproc.py start* it gives me an error (it tells me that the service timed out against the start or control request). If I go to Windows 7 services and try to run it manually it also tells me the error code: 1053. I've been googling so far and tried many solutions but none of them worked for me. I included python and their Scripts and DLLs folders to the system path, I incremented the ServicesPipeTimeout value on regedit, I tried to install it as my user, tried to run not as a python script but as an executable compiled with pyinstaller... It did not work. Does anybody know what could be happening?? I'm using Windows 7 Professional 64 bits and Python 2.7.13.

Thank you in advanced!
