Why or why not use AWS Lambda instead of a web framework for your REST APIs? (Business projects)

Hey guys! Im going to start a new project at work with a microservice architecture and I've been reading about AWS Lambda and I want to know why or why not use Lambda instead a web framework (Django, Flask; FastAPI, etc.)

Best resources to learn Django

Hi,
in the past I only used Flask and I like it a lot. But I thought I will try Django too because it might get me to working applications faster.

What are some good resources to learn the newest Django version?

Most of the stuff I found isn't up to date and maybe you got some recommendations for me.

Run Celery tasks on Railway

I deployed a Django project in Railway, and it uses Celery and Redis to perform an scheduled task. The project is successfully online, but the Celery tasks are not performed.

If I execute the Celery worker from my computer's terminal using the Railway CLI, the tasks are performed as expected, and the results are saved in the Railway's PostgreSQL, and thus those results are displayed in the on-line site. Also, the redis server used is also the one from Railway.

However, Celery is operating in 'local'. I need the Celery tasks to be performed without my pc's terminal doing it. This is the log showing the Celery is running local, and the Redis server is the one up in Railway:

Architecture Setting up a structure/architecture for a constant crawling and data saving platform.

Our company's client has multiple websites to track if they're down or not. And the CEO of our company wants us to build a new platform that constantly crawls the inserted websites and pings the user in the platform.

In our old system, the previous developer team used API's to save data coming from the crawler. If you add 1000 of websites, 1000x5 API calls are happening in an specific time gap, which made the system slow. Also, we have added subdomain tracking on the system, with which the system became super slow. And, sending data through websockets in the frontend to update what's going on made the system super duper slow.

I have got the responsibility for making a robost system that is super fast. So, I am here asking the question of how can I make the system robost, and fast.

Where to host the crawler, should we call APIs to save data collected by the crawler? What's the most optimized solution for this?

deploy one api (flask/fastapi/sanic/etc) as many Lambdas, one per endpoint?

Just an idea - I haven't given it a lot of thought, but I'm wondering if this is possible or even worth considering.

It seems like it might be nice to develop an API as one cohesive "thing" using a framework such as Flask/Quart/etc but then instead of deploying it as one site, have it deployed such that each public endpoint becomes its own Lambda on AWS. Or function on Azure, GCP, etc.

Hoping to generate a discussion and see what others think of this idea.

Add StreamBlock child items programmatically in Wagtail

Hello, I have the following setup for a pricing page on Wagtail:

class PricingPage(Page):
    plans = StreamField(
         [("plans", PlanListBlock())],
         use_json_field=True,
     )

     @property
     def plan_count(self) -> int:
         try:
              return self.plans[0].value.count
         except (IndexError, AttributeError):
             return 0

class PlanListBlock(blocks.StreamBlock):
     """A collection of price cards"""
     plan = PlanCardBlock()

class PlanCardBlock(blocks.StructBlock):
     """Price Card with a plan's name, price"""
     title = blocks.CharBlock(required=True, help_text="Plan's title")
     currency_symbol = blocks.CharBlock(required=True, max_length=3)
     unit_amount = blocks.DecimalBlock(min_value=0, max_value=100)

I'm having trouble testing the plan_count method. Specifically, I'm stuck trying to add a new plan to an existing pricing page with no plans programmatically (I'm on Wagtail 4.1).

My challenge is to take a PricingPage instance I use for tests and

Django project complexity

How can I know if my Django projects are good enough and complex enough so I can present them as my portfolio projects?
Currently I have a to-do list (creating, updating and deleting tasks with login/register functions), a blog(similar to to-do list, a bit more complex), an app that tracks stocks prices using an API and I'm currently working kn a Ecommerce store(combining Django with JS).
Should I focus on improving these apps or should I create more complexed apps?

Updated documentation for ScreenPy which should help you understand Screenplay Pattern, we think, we hope.

'Sssup, snakes—

I'm back with some updated documentation for ScreenPy, which is our Screenplay Pattern base suite for Python. If you haven't heard of it—that's not surprising—it lets you write tests that look like this:

def testexample(Snoo: AnActor) -> None:
given(Snoo).wasableto(LogIn.using(USERNAME, PASSWORD))

when(Snoo).attemptsto(
Visit(POSTURL),
MakeNote.ofthe(VotesOnThePost()).as("votes before"),
Click.onthe(UPVOTEARROW),
)

then(Snoo).should(
See.the(VotesOnThePost(), IsEqualTo(thenoted("votes before") + 1),
)

We recently rewrote our entire documentation with a focus on showing how to build a suite using a made-up Ability, which showcases way more of the modular, composition-based approach that Screenplay Pattern uses.

Our goal is to present ScreenPy and Screenplay Pattern in a way that is easy to follow and hopefully exciting to read about. Please let
