Which libraries or technologies could help to create multiform (Django)
Hello! I want to create booking multiform with simple step-logic: Select date, available in database (DateField "date"); Select time for the date, selected at first step (CharField "time", just 4 times a day available); Contact form (name, phone, etc).

GetStream.io returning activities in wrong order
I'm running across an extremely strange bug while using GetStream: i'm running a script to migrate over 200k activities (previously used an internal stream-framework fork) and I'm running across a really bizarre issue. The problem is this: I'm setting the 'time' field to a custom value (usually in the past). Now: these activities are being ordered wrong by the API. Although the activities being added have correct, ISO8601 UTC times in the past, the oldest ones are coming back on top of the feed (mixed with only a couple of new activities). This is really odd and I'm at the end of my wits -- this seems like an issue on Stream's end. Thoughts? Below is a screenshot of the issue. -
How to control Raspberry Pi with a web application deployed on AWS?
I have a Raspberry Pi with sensors, relays and actuators at home. I have no public IP address and to get access to my raspberry I should use, for example, a service like ngrok. But I'd like to create a web-application and deploy it on AWS (VPS linux server). It should be secure and support authentication. I imagine it as a dashboard. Data must change dynamically (like with AJAX). I don't need a stunning look, CSS support will be enough. Which technology stack should I use? 1. To connect the raspberry to VPS. Should it be VPN or SSH? How to organize access to data? Should UNIX-sockets or something similar be used? What if I have several boards on the network? 2. To implement a web-application. Although here it's overhead, I intend to use Django, because anyway I need to acquire this framework. But how to organize data exchange using WSGI? I want to add, I'm new to web development. Therefore, the solution should be as simple as possible. And the solution should be implemented with Python. I’m also going to learn JavaScript to use it in my full-stack pet projects. -
Django all-auth: How to disable automatic login via Google
I'm using the django-allauth package to log in users to my Django app via the Google API. My problem is that when a user successfully logs in via the external Google log in page, then everytime he logs out and wants to log in again, django-allauth automatically logs him in without redirecting him to the Google sign in page. How can I disable this functionality, and instead have the user redirect to the Google log in page each time he wants to sign in? (Ι have already tried ACCOUNT_SESSION_REMEMBER = False). Thanks! -

Which Django testing strategy should be used
I'm in the process of writing tests for my Django website and I'd like to understand what's the actually difference (and what is better, more suitable) way of testing views.py files. From documentation there are two ways: let's call it simple - described here https://docs.djangoproject.com/en/3.0/topics/testing/tools/ advanced testing - https://docs.djangoproject.com/en/3.0/topics/testing/advanced/ Approach #1 is working ok and I can do e.g. request that will return everything I'll see on the page. Approach #2 appears to be more precise in the way I can ask for exact function within class-based view. Also I see this approach dominating in Django's internal tests. Which way is preferred when it comes to Django testing? -
