Glowscript in JupyterLab

I believe I read that currently there are no plans to have JavaScript implemented in JupyterLab. This would mean that Glowscript would no longer be supported. Am I reading this wrong, or are glowscript’s days numbered with Jupiter? Or perhaps Jupyter notebooks will be around for the foreseeable future? I think many physics educators would be interested in knowing if glowscript will still be supported.

[AF] It's 2018 - how do you document your REST APIs in Flask?

Hey everyone, I'm currently using Flask as a RESTful API endpoint using Flask-RESTful. At the moment I'm just writing the API without any sort of documentation at all. I have no idea where to turn to learn about building documentation for my APIs, or if Flask-RESTful is still even the consensus king for setting up REST endpoints in Flask. Most documentation I can find on this subject is years old.

So my question: it's 2018 - what is everyone using for RESTful API endpoints + documentation in Flask?

Running a python script together with django - best practice question

Hi, this is very tangential to regular python programming, but maybe you guys have encountered the same problem!

I'm building a web-app that needs support from a script, or other application running on the server. The function of the script is to match entries from an order model.

Short-code: matcher.py

from app.models import item1model, item2model, madematchmodel
import time

While True:
item1=item1model.objects.get(identifier='id')
item2=item2model.objects.get(identifier='id')
if match:
match=madematchmodel(item1=item1, item2=item2)
match.save()
else:
pass
time.sleep(5)

As you might notice I'm a novice at both django and programming in general, am I breaking any major rules by having a constantly running While True:-script here?

What is a better way to accomplish this?

Where is Django's under the hood stuff located?

Watching the command line drift by I notice references to files that aren't in y project files, and when I get errors also. I am wondering where these files are? I' just curious as to how things work under the hood.

[AF]ForeignKey is always OFF and not working between tables in SQLalchemy in Flask

My code for db in Flask and SQLalchemy is working but when I make comment in post, ForeignKey doesn't link comment with that post and there is no value for post_id in table "comment" when comment is created.

Do you please know, what could be wrong? Tryed using Pragma to force foreignkey, but it didnt help. Tried to enforce ForeignKey ON with sqlite> PRAGMA foreign_keys = ON; but it does not persist.

Thank you

Helping LibreOffice in Python

People post here periodically looking for projects to work on to better their skills. I can recommend helping out LibreOffice: https://wiki.documentfoundation.org/Macros/Python_Design_Guide

Most of the work in LibreOffice is in C++. It ships with a Python interpreter, and has some scripts for QA, and Wizards, and a simple grammar checker, but there's not much going on currently: https://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=python

If people who want to improve their Python skills also want to help a production codebase, it's a good place to go. LibreOffice is important to the free desktop, and the work could get used by many people.

They also have a few Easy Hacks as a way to start: https://wiki.documentfoundation.org/Development/EasyHacks/by_Required_Skill/Skill_Python

I did some C++ patches to make it look good on HiDPI screens. I'd post a link but the development process is so different between Python and C++ that it wouldn't be useful ;-)

LibreOffice is missing even basic plugins to Wikipedia and WikiCommons and the CC Flickr, smart grammar checkers, etc. There are many ways to make LibreOffice better via little Python plugins. Here's the grammar checker which gives a sample: https://cgit.freedesktop.org/libreoffice/lightproof/tree/

Radioselect widget for forms.BooleanField creates a 3th, empty value option besides of True/False. how do I remove that option?

I've followed https://stackoverflow.com/a/3961084 to set a booleanfield to display 2 radio buttons with custom text for the True/False values, but it creates a 3th option , labeled "-----".
this button has a blank value. Looking at the POST values, selecting it does set`'add'(the booleanfield) to ['']`and gives a `ValidationError at (an url) ["'' value must be either True or False."]` How do I remove it?

Never mind, found it at the django docs.

If the model field has choices set, then the form field’s widget will be set to Select, with choices coming from the
model field’s choices. The choices will normally include the blank choice which is selected by default. If the field is
required, this forces the user to make a selection. The blank choice will not be included if the model field has
blank=False and an explicit default value (the default value will be initially selected instead).

Backdoor in ssh-decorator package

Do not install or use the [ssh\-decorator](https://pypi.org/project/ssh-decorate/#files) package from Pip. It has a backdoor inserted to steal all your SSH credentials. I've already contacted the developer to take it out. He hasn't responded so for now, use at your own risk! [https://ibb.co/kdDk67](https://www.linkedin.com/redir/redirect?url=https%3A%2F%2Fibb%2Eco%2FkdDk67&urlhash=SFzn&_t=tracking_anet)

**UPDATE:** The compromised package has been taken down now.

Django rest and React

So i just started with django rest and front end frameworks e.g react. From what I've seen with react is that we fetch data from a rest api. We only get data and we build all our logic as to what to do with that data in react.

So here's my question: I've built apps with django before. I've had to create views, forms signals etc etc. however will this be the same case when I want to make a single page application using the rest api? I mean in this case my django application will only serve the function of providing an api right? it will not have anything to do with views and forms logic? all of that will be done in react ?

Basically my question is this: If i want to make a single page application. Do I only need django to serve as a data storage which will provide an api and build all the logic and stuff in the front end e.g angular, react or vue etc?

Multiple apps, same login.

I am currently running a flask app under `mysite.com`. Now I would like to add a second flask app that will run under a subdomain, say `new.mysite.com`.

What I would like to do is have the main app handle the user authentication so if you login in `mysite.com/login` you are good for `new.mysite.com` too. Right now I am using the flask-login plugin for the main site. Ideally I don't want to add any authentication code or deal with the user database in the second app, but my understanding is that I still need a login manager and a user loader.

What is the proper way to implement this?

Email authentication

I'm on a subject of creating/authenticating accounts. Now when a user signs up, I want them to use a valid email. (Gmail, Yahoo etc.) And not fake one time use emails. Whats the best way going about doing this? I've been looking at creating a list of valid email address endings

ie. Endswith @gmail.com, @yahoo.com.

If it matches those it would be valid. I'm not sure if there is a better way...Thoughts?
