Dynamic behavior with multiple tenants

Hello,

I'm working on a project that, once complete, will allow organizations (which have multiple users, some of which may overlap with other tenants) to interact with a third-party API. The bulk of how the users for each tenant interact with the API will be the same between all tenants; however, each tenant may also need some customization that allows its users to interact with the API in ways that are specific to that organization's needs.


I'm not sure how to go about implementing behavior like this. Is there a Django-approved way of doing it correctly? I'm thinking I'd like to identify each tenant via a subdomain, but how I can then use that to point toward specialized behavior for the users within said tenant is where I get stuck. I believe I have everything figured out besides this.

Any feedback is appreciated. I'm still quite new to Django development, so I apologize if this is a simple question.

Here is a diagram showing what I'm trying to explain: https://puu.sh/Jp77s/1f4167f73a.png

Does there exist an example of a slider that trims a video?

I'm trying to find existing code that has an example of a modern slider GUI where you can move the slider from both the head and tail as if you're trimming a video?

​

Can't find an example of one using Django.

Output red in iPython

For some reason the standard color for Out in iPython appears to be red:


In 3: f()
Out3: True

In 4: 3
Out4: 3

Both “Outs” are red.

It makes it look like an error.

Is this just a design choice or is there something wrong I don’t know about?

Thank you

Puff - Python GraphQL engine and WSGI Runtime - Use Django on Rust's Tokio

Hello,

I wanted to share with you my recent experiment for Django, Puff: https://github.com/hansonkd/puff

The idea for the project is that there are an incredible amount of Django resources and developers out there and that Django makes it so easy to get an app running that it should be used as the primary developer layer for managing DB tables, Admin, Auth, etc.

But understanding Python performance means understanding the GIL. For parts of your code that are performance critical, as much work should be handed off to Rust as possible to avoid locking the GIL If you are constructing a response with thousands of rows, it doesn't make sense to iterate through that in Python creating a python dictionary only to convert it to JSON. This holds the GIL in the least effective way.

Puff is designed to allow you to pass off Python Objects to Rust to take advantage of Rust's async runtime. For example, in Puff's GraphQL engine you can hand off pure SQL strings from Python to be executed entirely in Rust, transformed to JSON bytes, and sent as an HTTP response without locking the GIL again.

You can write your own Rust functions that use any Rust library. Even when you

jupyter_nbextensions_configurator - error messages in JupyterLab startup

Any info on how to make these error messages go away?

*(I posted this same question into* r/JupyterLab *a couple of days back, but have not got any responses so far. I presume this* r/JupyterNotebooks *Subreddit can also consider JupyterLab questions).*

TBH not serious in that I am not aware of any components not actually working - but I prefer not to have nuisance errors in logfiles, lest they obscure items of real concern.

There are various lines in the JupyterLab server startup log relating to the configuration of jupyter\_nbextensions\_configurator - with the last one indicating that it failed to load. Console log below.

Versions of components in use listed below - as far as I know they are up to date (with Python 3.10.5). I have tried deleting and re-adding components with conda. Does not improve things.

Any info on....

\* what this failure to load actually implies (I am not aware of anything not working)

\* how to make this error message go away

thanks

Dynamically update periodic tasks in Celery and Django

I'm working on uptime monitoring web app (with Django, of course). It is a simple web app that pings the server and sends an email when the server is down. During the development, I need dynamic periodic tasks in Celery. My use case was:

- user adds server for monitoring with time interval - she creates a new periodic task,

- user changes the interval or pause monitoring - she updates the periodic task,

- user deletes the monitor - she deletes the periodic tasks.


I was looking for a nice way to manipulate periodic tasks in Celery. I found an amazing `django-celery-beat` package that provides PeriodicTask database objects. With PeriodicTask objects, you can dynamically add/remove/update periodic tasks in Celery. I want to share my approach. I've created an example GitHub repository and wrote step-by-step article.


What is your approach for dynamic periodic tasks in Celery and Django?

IPython terminal would display a string with \n in the same line, how to change this behavior?

given a snippet in IPython terminal

s = 'AAA\nBBB'
s

it would give 'AAA\nBBB' as output.

I have to call print(s) to get

AAA
BBB

Is there some config to make IPython's display to show the \n in a string as linebreak?

Jupyter Notebooks on EC2 Windows Instance

I have googled this for a good hour now and can't find any mention of running Jupyter Notebooks on an EC2 Windows Instance - specifically running Jupyter after remote-ing into the machine.

1 - Is this possible?
2a - If not - why not?
2a - If not - what is an alternative notebook that will work on an EC2 Windows Instance?
3 - If so, any one know of a guide to get it up and running somewhere?

Text Corpus Tagging System

I have a feature idea for an app I'm helping develop, and I'm wondering if it makes sense before I go too deep down the rabbit hole.

I want to find a way for a front-end user to edit a large text document and add a custom ID tag to a certain section of text of arbitrary length. My initial idea is to store the text as HTML and use a WYSIWYG editor with most of the functionality disabled, and just leave the ability to highlight a range of text and choose an ID attribute from a pre-defined list to add to a <span> tag or something like that. Would that work? If so, any recommendations on a WYSIWYG editor that would work well with this? Or is there a better way to accomplish this?
