I created a flask app for my cs50 final project. It was successfully deployed to Heroku via Github, but for some reason it's not working.
When running locally with flask run it works fine though.
My project folder is organized like this
The Procfile content is the following:

Answered 2021-Jul-24 at 04:24I deployed your app on my heroku. There was no error like no web proccess running.
You can see whether any dyno is attached by going on overview tab of heroku.
Still the gunicorn worker failed to boot. The reason is that you are not defining host and port parameters in app.run()
it should be like this:

Trying a simple python flask web app in docker 20.10.2, build 2291f61.
Doing the: docker build -t hello-world . starts out ok (please see below), but ends with:
ANSWER
Answered 2021-Feb-27 at 01:41You should change the RUN lines in the Dockerfile with apt-get in them to use the -y flag to skip asking you to confirm "yes".

QUESTION
I am trying to get the logic of using jQuery AJAX and Flask, however I am not coming right. I have been following tutorials here and here, but no resolution. To get the logic - I simply want to input dates in two separate fields, and return those dates to the same page in a normal
tag. My suspicion is a problem in the server receiving the dates. Submitting the relative form does not return anything to #result
HTML FORM
...ANSWER
Answered 2021-Feb-05 at 21:58Please use the button to send the form, an anchor within the form does not make sense.
I would advise you to use the "submit" event
of the form, although the "click" event of the button would also work. The preventDefault function bypasses the standard behavior of the form, so that you can send the form yourself using getJSON. To serialize the form data, I use the serialize
function which converts all form data into a conforming string. Thus the data is sent as "application/x-www-form-urlencoded".
The variable $SCRIPT_ROOT is not used by me in this example because it is
basically empty under localhost and is not absolutely necessary.

Answered 2020-May-12 at 10:37It's probably because you are trying to access /login with a GET request. You have 2 options:
- Allow
GETrequests for the/loginendpoint (which is probably not the best way to solve this):
