[Hh#49011] Deploying Flask

[HelioHost]

Hi,

im trying to deploy a flask app in tommy, i've followed https://www.helionet.org/index/topic/27822-how-do-i-use-flask-on-johnny/?p=128919 with no success, i've got "Internal server error".

 

i think some libraries are missing, but i dont know how to install them (mercadopago, wtforms, flask_sslify, etc).

 

i've also tried to debug the app, and it seems to be an error in vars declarations.

 

What can i do?

 

Thanks!

Whatever mail client you used doesn't seem to agree with our mail processing scripts. Since the subject has the word flask have you seen this guide?

[HelioHost]

Maybe i should upload my flask.wsgi file? My app is called views.py

 

import os, sys

 

# edit your username below

sys.path.append("/home/susoft1/public_html/flask");

 

sys.path.insert(0, os.path.dirname(__file__))

 

from views import app as application

[Krydos]

Line 7 of dispatch.wsgi calls

 

from views import app as application

 

which loads up views.py and it encounters an error on line 111 because the tabs and spaces are inconsistent. A common reason for this error is using a tab in one place and four spaces in another. They look the same in your editor, but it will cause this error. Check out https://stackoverflow.com/questions/5685406/inconsistent-use-of-tabs-and-spaces-in-indentation

[HelioHost]

Ok! I've solved indent problem. But same error appears. What log says?

[Krydos]

Yep, you fixed the tabs/spaces error. Here is the new error:

Are you sure you can't replicate these errors and solve them yourself on your home computer?

[HelioHost]

I'm really sorry about the lot of questions i'm asking. And thank you so

much for the help. It's very useful.

I've solved this new error, but same 500 error appeared. I've also run the

code in my pc, and works fine (same with other host)

[Krydos]

You're fine. I don't mind helping people. My strategy is usually to teach people how to solve their own issues though rather than doing it for them. I guess if you really can't get any of these errors to appear on your home pc I'll just keep posting error logs for you.

[HelioHost]

Oh ok, it's about another missing module (wtforms), could you please

install it?

[Krydos]

There you go http://krydos.heliohost.org/cgi-bin/modules36.py

[HelioHost]

Thanks! And what's the new error?
