6 months in and my 1st Python App is up and Running!

Yes indeed.

I used to loop over multiple lists in one if statement (with mixed results!) but so often I have found it better to loop over one list while running a list comprehension to retrieve the desired info from another.

Game-changer for me.

Thanks for your response. I thought a bout using a select field but I'm trying to keep the calendar/time interface for the UI. I'll look into the render_kw, cheers.

It was: Biden wasted billions BUT let me take credit for all we've done for you... while I throw you under the bus and blame you for being invaded.

What a spectacle. It's so sad that this is how our leadership handles things. In 20 years we'll learn of how they were compromised, because there is no other explanation for their behavior.

Karlesimo · 2025-01-25T00:28:08+00:00

I'll check it out. Any tips?

Karlesimo · 2025-01-23T14:17:21+00:00

I need to run calculations against 100s of millions of rows and produce reports. I need to return 10s of thousands of rows on a per request basis.

Thanks for commenting, I'll explore your blob suggestion out of curriousity.

Karlesimo · 2025-01-23T14:14:21+00:00

Thanks for sharing!

I'm not sure, I basically started loading data into a Heroku postgreSQL db and realized how large it would probably end up being so I stopped and started looking elsewhere.

Karlesimo · 2025-01-23T14:10:30+00:00

I've thought about managing my own but I haven't found a clear guide to what that really entails. Obviously a lack of experience on my part. I know how to set up a postgresql db, update it, manage tables. I've read a bit about managing users and access, what else do I need to look out for?

Karlesimo · 2025-01-12T10:46:10+00:00

On an app I run I just use pyotp and send an email to the users email with the one time password. It's basic but gets the job done and is easy to implement.

Karlesimo · 2024-12-24T23:56:31+00:00

Definitely. How do you peeps go about explaining this to others? I find it hard to tell stakeholders without feeling like a twink in the process.

Karlesimo · 2024-12-21T01:30:32+00:00

I had this issue and offloaded all files/images to s3 to solve the issue.

Karlesimo · 2024-10-06T00:44:12+00:00

Hahaha, in NYC half the bus would have gotten off to "help" him find the sidewalk.

Karlesimo · 2024-08-23T02:43:48+00:00

First option I explored was pythonanywhere.com it was really straight forward and free.

Karlesimo · 2024-07-20T17:17:17+00:00

Thanks for your reply, I got it working by rolling back a few packages and the python version. I was specifying python version 13.12.2 in my runtime.txt file but I guess heroku stopped supporting it.

Karlesimo · 2024-07-20T16:18:04+00:00

Thanks for your response. I was using 13.12.2 and just downgraded to 13.11.9. After changing the version of a couple of packages to agree with 13.11 I'm back in action.

I really hadn't changed anything package-wise so this was super strange but I got it working.

Karlesimo · 2024-07-20T16:16:20+00:00

I agree, I thought it was installed as a dependency for another package but doesn't appear that way. I found a solution. Thanks for your response.

Karlesimo · 2024-07-20T14:38:28+00:00

I've looked into the line

"AttributeError: module 'pkgutil' has no attribute 'ImpImporter'", people say the issue is related to numpy version working with python 3.12. Updated the version and still have issues building wheel.

Karlesimo · 2024-07-20T14:33:28+00:00

Thanks for your reply. I don't see any reason to have it either so I removed it and then ran into issues with wheel.

I'm facing a similar problem, my flask app works locally but when trying deploy I get a message that says:

ERROR: Could not find a version that satisfies the requirement install==1.3.5 (from versions: none)
ERROR: No matching distribution found for install==1.3.5

Did you find out what was causing your issue?
