Does Beautiful Soup web scraping refresh the page?

I’m web scraping a website that has a live tracking ticker (count of subscribers).

I read somewhere that web scraping refreshes the page which makes the web developers “unhappy”. However, since I’m simply monitoring a css label.... is it still messing up something on the user side? Possibly giving him too much traffic?

Trying to get username for a query in a form.

Hi,

I have the following form which I've made after reading stackoverflow questions.

class PayForm(forms.Form):
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user',None)
super(PayForm, self).__init__(*args, **kwargs)

print(self.user)

date = forms.DateField()
total = forms.IntegerField()
#company = forms.ModelMultipleChoiceField(Company.objects.filter(employees=self.user))

my issue is I get a name error for self when I uncomment company, the init seems to work but it appears to be called after the variables are set. anyone have a clue what's up with this?

basically what i'm trying to do is this:

I have a model for companies, in that model I have a manytoomany field which can be populated by several usernames, in my form I only want that user to be be able to select companies that contain this user.

Can I use Flask for only the database, but create all the front end in Html, CSS, and some JS?

So I am a beginner and I was following Corey Schafer's Flask tutorial when I ran into a huge problem and couldn't debug it. I was forced to scrap it and I wanted to try again, but this time only use SQLAlchemy for the database part, and Html/CSS/JS for the front end. Is that possible or do I HAVE to use the exact html and css?

Best Way To Start Learning Python - A Complete Roadmap

Python is one of the most popular language among programmers.

Now the question is ***where to start? How much time it will take to learn this language? what topics you should cover? what are the Python libraries or frameworks?*** As a beginner, you will be confused that what should I choose first.

Should I learn all the concepts from a book or should I go for an online tutorial? Let’s discuss the [Entire road-map to become a Python developer.](https://www.geeksforgeeks.org/best-way-to-start-learning-python-a-complete-roadmap/)

How to handle file uploads in Django Rest Framework?

Hello!

I'm currently working on a Django API in the Django Rest Framework. The API needs to be able to support ( and I suspect - a lot ) of file uploads more or less simultaneously. The file sizes may vary wildly. The application needs to analyse and then destroy the files.

I'm having trouble with the research for this issue, as there doesn't really seem to be a production ready solution out there.

In Flask I would probably use some sort of multi upload and maybe something like Celery. Does Django have it's own "worker" implementation? What would be the most optimal way to handle a lot of "analyse this file for me" requests?

Build a web app in 20 minutes

Beset by pandemic, smoke and 2020 in general, I have found solace in creating a generator that creates multi-table, multi-form apps for sqlalchemy databases. It enables you to build an app in 10 minutes.

It’s based on Flask AppBuilder, itself based on Flask and SqlAlchemy.

Anyone doing Monolithic Django?

Printing a hello world over kubernetes cluster is an overkill, so are multiple microservices when you do not need them. I loved monolithic django, but with the advent of microservices architecture and modern JS libraries react, vue, and the likes, here is what you got to do

​

1. Create a DRF Backend
2. Take care of authentication at both ends
3. Build your SPA in a modern JS framework.

The good is modularity, maintainability, better UX controls, super interactive UIs, and the likes, the bad is you need to write more code. In simple cases the good old django templates is good enough. Is anyone still doing them? I love the organised new age FE framework code, the imports that come with ES6.

​

Is anyone still doing monolith with django template and ES6. If so, mind sharing your workflow, and libraries?

Django ORM

I am developing with Django for a couple years now. The documentation is great but I don‘t seem to get many concepts of advanced querying. Can you recommend any resources that take a deep dive into the topic with explanations and examples?
