Call for maintainers for Celery's Django integrations

Since we're beginning our efforts to develop Celery 5 all resources are going to be directed to that effort.

Unlike Django, Celery has a very small team which we are looking to expand.

Part of the reason for expansion is because we no longer have the time to maintain the Django integrations properly.

​

If you are interested in maintaining our Django integrations, comment here or message me.

The best way to prevent a django model choicefield from saving any value not available in choices

I have a choice field for my Post model called privacy\_setting. Currently, in my PostSerializer, where I save the post with the validated data, I am somehow able to save any value in the privacy\_setting field that is not available in the choices section. What is the best approach to prevent this from happening?

> post = Post.objects.create(
text=validated\_data\['text'\],
owner=validated\_data\['owner'\],
privacy\_setting=validated\_data\['get\_privacy\_setting\_display'\])

My Post model field:

> privacy\_setting = models.CharField(
max\_length = 2,
choices = POST\_PRIVACY\_CHOICES,
default = PUBLIC
)

A package I want to use contains Linux paths for reading data and configs. Is there a way I can use it on a Windows machine without editing the source code?

This [very interesting ML package](https://github.com/facebookresearch/habitat-api) just came out, and like most such packages (especially in early phases), it seems to be designed primarily for Linux. For example, this code:

`env = habitat.Env(`

`config=habitat.get_config(config_file="tasks\\pointnav.yaml")`

`)`

returns an error since it wants to read another file from a path that uses forward slashes. Is there a way to get python to automatically "translate" files to work with Windows paths? In principle it shouldn't be too hard to tinker with the paths in one package, but since this seems to be systematic to many packages it would be quite handy to have an easier way to do it.

​

Thanks!

[Ask Flask] - Utilizing Flask for Obfuscating/Protecting Client/Server Python Application

My team and I are working on a project currently in Python 3 that utilizes a client/server communication model. Both our client and our server are written in Python 3, with the client utilizing the Kivy Framework for a GUI. All of our client/server communication is protected with strong, third-party audited encryption, with any communication between clients being protected by end-to-end encryption. My team and I would like to eventually release this code as an app both on desktop and mobile devices. However, because Python doesn't really make use of anything to protect code, we are hesitant to just throw our client .py file out there to be read (and copied). We are a very small team, and we worry that our idea could be easily snatched up by a company with massively more resources and funding while in it's early stages.

Since .py code can't really be obfuscated well, we were recommended to take a look at Flask for the purpose of using a web server middleman to mask what's happening behind the scenes. If I understand correctly, essentially we would have our GUI client communicate over Flask (I'd assume something like HTTPS?) with

What Django e-commerce application/package/framework do you recommend?

I am looking for a good application/package/framework to handle payments for websites that I want to build. I like to use frameworks that are very versatile and offer al lot of options, I am not afraid to go through a steep learning curve or something like that to learn to use the framework. What framework do you suggest to use? I am considering django-oscar but I don't really know anything about my options.

Online based Python groups?

Hi guys, I was wondering there were online like meetups or groups?

A review of 5 Python Deep Learning Computer Vision Courses (WARNING LONG).

Hi guys,

So I'm working at a startup where as the 'Chief' Data Scientist (re: only person), I was tasked with learning computer vision for a new application we're developing.

My background is in Mathematics, I've used R extensively. I know some Python for a course I completed in College, but I'm not pro. Previously, most of my work involved performing Data Analytics, with some simple modelling.

The company paid for all courses mentioned below and I took roughly 3 months to complete almost all of them (still had most of my full time tasks to do, so I wasn't dedicated 100% to learning Computer Vision).

**The courses purchased and their price below:**

Programs that are against Terms of Service

Hello everyone,

I created a Python program with Selenium to automate my user activity on a website. However, in the Terms of Service of the website, it specifically states that automation is prohibited and they don't have a public API. I haven't invested any money in development nor have I spent very much time developing the program so I'm not heavily vested in this project, but it seems to me like just walking away is giving up too easily. I also don't want to get into any trouble, but the program is useful to me and could be useful to others if I decide to sell it in the future.

Has anyone ever been in this situation where a program you created was against a site's Terms of Service and if so, did you still use it or did you just move on to something else? Additionally, is Selenium easily detected by websites if I only run the script a few times a day? Any feedback would be greatly appreciated.

Search functionality

Hello,

​

I am seeking an advice, ideas and best practices regarding to a search function implementation. I have a database of items that have names and descriptions and I also have a bar on the website that requests a search through the items.

​

Currently, I have it made with nltk currently, it simply tokenizes and matches against the contents of db entry (its not super accurate). I was wondering how you guys have implemented it, if you did.

Thanks

Edges of 3D surfaces produced using Mayavi seem "rough" or "jagged"

Hello, I'm currently trying to imitate the code done in Matlab which were used to produce these 3D surfaces (see here http://davidbrander.org/Images/index.html) on Python. I've decided to use Mayavi.

Before diving into the project, I've decided to learn Mayavi using the standard examples. Here's a well-known example of Boy's surface, which is also Mayavi's logo -- https://docs.enthought.com/mayavi/mayavi/auto/example_boy.html#example-boy.

Here's a screenshot of the surface generated by the code:

Notice that the edges aren't smooth, unlike the really nice pictures by Brander. What should I do to fix this on Mayavi?

Admin list view: a FileField is displayed as a link going nowhere

I ran into this implementing my own app but I managed to reproduce it in the official Django tutorial's project (the Polls app). If I add a FileField to a model and add the field to `list_display` on the ModelAdmin implementation, the resulting list view will display a link for the FileField's value: [screenshot](https://i.postimg.cc/tRM3PXTY/image.png) as if were an object's change link. The link obviously doesn't work and returns a

> Question with ID "sample.srt" doesn't exist. Perhaps it was deleted?

error. Using `list_display_links = None` or `list_display_links = ['question_text']` didn't change this (in the latter case, it did provide a functional link on that column). I know I can work around it using

def file_name(self, obj):
return obj.file_obj.name
file_name.short_description = 'File'

list_display = ('question_text', 'pub_date', 'was_published_recently', 'file_name')

But what am I missing here? So far the implementation of the admin has been pretty straight-forward if you understand the various points to make the changes, but this puzzles me why this would even happen out-of-the-box if it's broken out-of-the-box...
