Do all the databases work the same in django?

I think this is a stupid question but i have to ask. I'm a total noob and just started working on django. It keeps scaring by saying over and over again that we should use other databases for larger projects.

Honestly, i have no clue what this means. Moreover i don't have any experience with databases. I started learning python 3 months ago and now i'm thinking i should try django.

What i want to know is if the databases work the same in django? Like will sqlite3 and postgresql work the same or will i have to learn something before doing it? And should i learn databases before learning django or not? IT would help me alot if anyone could clear these things up for me.

Security best practices for Javascript generated field.

I'm using flask_wtf FlaskForm. I would like to sanitize string user input for a JavaScript generated form field. Now there are plenty of external libraries to do this, but I was hoping to find a way within the existing libraries. Any ideas?

Linking results to a notebook

In my work, I do a lot of 'misc' data analysis..and I often am in a situation where I send out results, then a month later, someone asks me to rerun or change something etc... what bugs me is not having to figure out which notebook produced a given results file. has anyone thought of a good system for this? I have thought of including the notebook name as part of the results filename..or maybe somehow including the notebook name in header data depending on the file type. I'd love to hear some recommendations.

Code Review request

Would anyone be kind enough to review my project.

It's...rather large and most of it is in spanish (well, spanglish). Do have a readme that I think covers most of it.

ValueError: Unhandled pending operations for models

ValueError: Unhandled pending operations for models:
lists.list (referred to by fields: items.Item.list)


I'm getting this error when I try to migrate. I realized that it recently started happening after I installed django tastypie and started using it to make my API. Not sure what the error is exactly I haven't really modified my models much since then.

[D] openAI closing down gym toolkit website

If you go to https://gym.openai.com/ now it just redirects you to their github repo. There was no official statement about it, the site just went down out of the blue. Only source about it actually closing down right now is Greg Brockman's reply on twitter.

https://twitter.com/gdb/status/907855318591438848

> Yep, the Github repo has been the focus of the project for the past year. The Gym site looks cool but hasn't been maintained.


It is really sad news for me personally. The companion website was very useful, both as a benchmark and source of information on practical algo implementations and tricks via writeups. Greg mentioned lack of maintenance, but it I think it was good enough for what it offered.

Maybe if community lets openAI know website will be missed they'll reconsider?

[AF][flask-mail]Recursion error on flask-mail connection attempt

I'm getting a recursion error when I attempt to connect to my hMail server that I set up for testing purposes. Both my Flask server and hMail server are on the same computer at 127.0.0.1. The traceback is as follows:

How to change directory inside a notebook ?

My project directory typically look like this :

home/
├── data/
│ ├── some.csv
│ ├── another.csv
│ └── etc.csv
├── notebook/
│ ├── myproject.ipynb
│ └── testing.ipynb
└── src/
└── script.py

I have set my configuration to launch my notebook in the home directory. Although I am having trouble properly loading files from the data directory.

My big challenge is that I am using Windows, Linux and Mac. I've used the OS module but my code doesn't work will all OS.
I can't find the universal code that would allow me to move from the notebook to the data.

Any help ?
