How to organize my django website

Hello all! I am super super super new to Django and python in general. I have begun the process of reading the documentation and going through tutorials and have come here for guidance.

The site I want to build would be for speakers at conferences to be able to upload their files prior to the event. I can easily wrap my head around having an app with a model of the general fields associated with this and a simple file upload form.

The part that I can't really figure out is how I would be able to have multiple conferences able to upload at the same time. As well as how non programming people would be able to set up a new conference to begin uploading to using only the admin interface.

Is there a way to create a new db table via admin interface? Should all of the entries just live in the same table with an entry determining which conference the entry belongs to? Am I being too ambitious for my first non-guided Django project?

Replacing a spreadsheet...

I've successfully used Jupyter before, as a beginner for a few machine learning lessons, but I'm wondering if it's possible to use/abuse Jupyter to behave more like a spreadsheet, just in terms of having cells depend on other cells and continually update.

I've always felt limited by Excel because I really want to document my thinking in the way that Jupyter allows, with markdown blocks etc. (Before getting into Jupyter I've also been using Calca for the mac.) I also feel limited by Excel's functions, while I'm very comfortable with software programming - there have been so many times I've thought, ugh, this would be so much easier if I could just call 'map' on this array of data...

So I've been hoping to find something like Jupyter, where I can actually write my own functions and document my thinking, but where I can also input new data and have it be persistently stored, and have other cells update to changed data.

I know this isn't exactly what Jupyter is usually used for, since it's more to explore data in a linear fashion rather than in a reactive-programming fashion. So I guess this is a dual question:

Is it possible to make Jupyter behave

Flask Email Validation - Stop Nonsense Emails

For example, I get some emails that are clearly nonsense like sfdjhkj@kjh.com...

is there no way to mitigate this or some kind of library/algorithm to verify the validity of an email?

Doesn't have to be 100% of the time just in general.

Discussion: What to call the "main" app in your Django Project?

I'm starting a new project and it will be a collection of Django Apps with their own functionality (as intended by the Django Framework). However, I usually create a home/base/main app for the landing page, all of the base templates, static files, ... What is the preferred way to call this or handle this?

Following Flask production deployment tutorials, how safe is it to host a small scale webshop using Flask?

I want to host a really small scale webshop - only meant for a Facebook group - on my Raspberry Pi. I've read that I need to properly deploy it for production, which I intend to do.

My plan is to store addresses locally and have PayPal take care of the payments.

How safe/unsafe is this? Is there something I oughta know before I make this?

Error in documentation

Hi,

I am a beginner. I was going through the getting started documentation and found some typos and error.

[https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views](https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views)

def detail(request, question_id):
return HttpResponse("You're looking at question %s." % question_id)

def results(request, question_id):
response = "You're looking at the results of question %s."
return HttpResponse(response % question_id)

def vote(request, question_id):
return HttpResponse("You're voting on question %s." % question_id)

Gives the following error:

return HttpResponse("You're voting on question %s", % question_id)
SyntaxError: invalid syntax

To solve the problem I performed

*return* HttpResponse("You're voting on question %s", question\_id) #excluded the '%' prefixed to question\_id

​

I am using Linux python3.7 django 2.1.5.

Will the changes be made or should I make an official report on their site?

If so, How should I sent the error to the django team.

How to Make a Desktop GUI Application in Python?

Nowadays Python is one of the most popular programming languages. Specialists value its universality for all types of the tasks. Today, one of the most important qualities is convenience of command execution, but often developers have to write a relatively simple program, the quality criterion of which is an intuitive graphical interface. You have several ways to do this by means of Python. The following development tools are among the most popular:

* [PyQt](https://pypi.org/project/PyQt5/). The widespread Qt library, which implementations are available in various languages. It’s written in C++ and is cross-platform. This library allows the development of applications that have familiar and ordinary appearance in the general sense of this word.
* [Tkinter](https://docs.python.org/3/library/tkinter.html)**.** This tool is often referred to as standard for developing GUI applications in Python, appeared back in the early 90s of the twentieth century. Due to the long history and ease of use, Tkinter has a rather extensive and active community. It’s thanks to it you can find a large number of semi-finished products or publications in the network and get an answer to any question at specialized forums.
* [WxPython](https://wxpython.org)**.** Another descendant of C++, namely WxPython, links the wxWidgets cross-platform library with Python. In some ways, Tkinter and

django-taggit vs PostgreSQL ArrayField - I know the differences, but what are the technical implications

Hey guys.

I'm currently working with django-taggit for my "Tag" fields, because for quick prototyping I just use sqlite. However now I'm almost done and I have to work on a more serious setup. I will be using PostgreSQL as my main production (and dev) database. And I like to use as few external third-party packages as possible. That includes django-taggit. I would like to replace this with a Postgres ArrayField. Since django-taggit uses a `form.save_m2m()` it looks like it just uses a ManyToMany Field. And I understand that also.

But I don't have enough in-depth knowledge. What are the actual technical implications? Are ArrayFields significantly faster? Are there any up/down-sides I'm not seeing for either of the two? Is there even any significant difference between the two?

Thanks so much in advance. I hope this is of interest to others as well.
