Not able to get app to host

[vivid wedge]

port issue and crashes

[silver pilot]

remove the build and start commands

[silver pilot]

what framework is this btw

[vivid wedge]

flask

[silver pilot]

okay, set the start command back, and set the PORT envvar on railway to whatever flask is listening on

[unkempt python]

Make sure flask is listening on 0.0.0.0 & not 127.0.0.1

[vivid wedge]

port ennvar?

[vivid wedge]

how do i do that

[unkempt python]

https://github.com/railwayapp-templates/flask/blob/a4b19048250acd6450460753e55b5f49a4b2e925/main.py#L13

[vivid wedge]

already did that

[unkempt python]

cool

set start command to gunicorn app:app & deploy

[vivid wedge]

this is what i did

when i started this post

^

[unkempt python]

why does it crash?

[vivid wedge]

im not sure

why does it ask if its listening on the right port

[unkempt python]

check deploy logs

what do you see there?

[vivid wedge]

init py file

[vivid wedge]

my run.py

[vivid wedge]

when the server crashed

[chrome terrace]

this file is named init.py?

[vivid wedge]

init.py

[chrome terrace]

then your gunicorn command would be gunicorn init:app but you also should use a more conventional name for the file. Either main.py or app.py. Will help prevent this in the future.

[vivid wedge]

__init__.py

[chrome terrace]

ah yeah it should not be in that file most likely. That is a python package management special file that is deprecated since python 3.6

is the tutorial you are following a bit old?

[vivid wedge]

last year

[chrome terrace]

they might know something I don't but my recommendation is to move the code into either app.py or main.py then whatever you chose pass to the gunicorn command

here is a minimal functional flask root file

then my associated gunicorn

[vivid wedge]

changed the starting command

still doesnt work

[chrome terrace]

if your file is called __init__ the name init wont work

since im not sure if you can pass __init__:app to guniconr that is why I am recommending changing the file

[vivid wedge]

i renamed it to app

gonna push it

[chrome terrace]

gunicorn app:app

[chrome terrace]

deploy log again?

[vivid wedge]

i need to import something?

server just crashed

how does me not being able to import something say am i looking at the right port

[chrome terrace]

what is your project structure? You should have app.py at the top level of the project, not under any sub directories. Also is that the exact line of code you have written app = application(__name__)?

[chrome terrace]

railway can't implement all the ways that everyones projects might break so it just makes an arbitrary guess

see this as a reference for why having your app in a subdirectory is non-default: https://stackoverflow.com/questions/16416172/how-can-i-modify-procfile-to-run-gunicorn-process-in-a-non-standard-folder-on-he

See my previous screenshots of an example minimal flask implementation for showing app = Flask(__name__), rather than app = application(__name__). Unless of course you have some auxiliary code that you havent shown

[vivid wedge]

then what is my run.py file is supposed to contain?

[chrome terrace]

some people like to split up their flask files a lot. Some don't split them up as much. Unless I see everything you have I can't answer that question. Maybe your project has separate init + run files? Maybe your problem would have been immediately resolved by writing gunicorn run:app? I don't know

[vivid wedge]

my run.py

app.py

app structure

what i get after changing all the commands, @chrome terrace

[chrome terrace]

thats good

that means the server is up and running now

all you need to do is define some routes

look for something in your tutorial that gives you @app.route and include that

[vivid wedge]

what do u mean

gives me @app.route

[vivid wedge]

this is on my local server

before this it was able to display the contents

now it cant because i changed it

[chrome terrace]

can you provide routes.py

[vivid wedge]

it has all my functions

[chrome terrace]

https://stackoverflow.com/questions/11994325/how-to-divide-flask-app-into-multiple-py-files this is essentially what you are doing

You can use any of the solutions here. this might be the easiest for you from this moment

This is how i do it for my project

[vivid wedge]

what file is test_routes @chrome terrace

[chrome terrace]

your equivalent file is routes.py. This solution is suggesting that you use this import trick to expose the routes from routes.py to the main app.py file

notice though that your run.py and app.py are completely unrelated to one another. They make no references. So consider the possibility that changes in one of those files might not affect your overall app, since it's not being used.

[vivid wedge]

im confused on what you want me to do right now

you say they are unrelated but you want me to change the contents?

[chrome terrace]

test_routes.py = routes.py

I wanted to confirm that your unicorn command is gunicorn app:app because that means app.py = app.py also

[vivid wedge]

yes here

[chrome terrace]

just following the first screenshot should be enough

[vivid wedge]

is this files switched?

[chrome terrace]

you only need to do one of these

[vivid wedge]

no module named routes

[chrome terrace]

what folder is routes in?

[vivid wedge]

application

[chrome terrace]

application/app.py
application/routes.py

[vivid wedge]

yes

[chrome terrace]

hmm that should just work - https://stackoverflow.com/a/57058634

[vivid wedge]

cant even run the application now

[chrome terrace]

well yeah a broken import will stop application from running

im doing my best not having access to the files, but there is just a lot of nitty gritty stuff that needs to be done that is non-intuitive when you are setting up for the first time. So it's hard to debug remotely like this

[vivid wedge]

correct?
