Problem with "unique" values

I'm currently working on my project and it has some values as *unique* and these values are being handled in an overwritten *get\_queryset* function and it is as follows:

```
def get_queryset(self):
data = self.request.data

categories = {
"carpet" : Flow.carpet,
"furniture" : Flow.furniture,
"eyewear" : Flow.eyewear,
"home" : Flow.home,
"shoe" : Flow.shoe,
"beauty" : Flow.beauty,
"accessories" : Flow.accessories,
"video" : Flow.video
}

project = Project.objects.create(name = data['name'], poster = data['poster'], glb_file =

Render **context as HTML in render_template?

Hello everyone! I'm in the early stages of developing a flashcard solution using Flask. The objective is to have users input HTML for both sides of their flashcards, which will then be rendered when reviewing cards. As a foundation, I have been attempting to develop a simple Flask application that takes an input and parrots it back, rendered as HTML.

I have encountered an issue in that when I return e.g. `flask.render_template("index.html", front="<h1>Hello World</h1>")` on a GET request, `front` here is shown as pure text (escaping tags) as opposed to being rendered as HTML. In other words, instead of a large "Hello World", it displays "<h1>Hello World</h1>".

Example code follows:

# main.py

import flask

app = flask.Flask(__name__)


@app.route("/", methods=["GET", "POST"])
def index():
if flask.request.method == "POST":
return flask.render_template("index.html", front=flask.request.form["front"])

return flask.render_template("index.html", front="Enter something!")

Is it good way to send request whenever model update?

I have to post model data to some websites whenever specific columns of models changed.


1) write request function as override model update function.

2) add a function and use it in the view class.


If I apply 1), I don't need to check when I should add a new function to send requests or not. It'll work well whenever the model changes in every function. But It seems pretty dangerous..

2) I should write the code if I add a new function to handle the model. So if I miss writing the function, that'll not send a post request.

which is the better way..? Should I make a function to send a request? or override the update function in the model?

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
