Difference in setting up test client inside a client fixture

Hi. I'm learning Flask and Python in general, and I'd like to know if these two ways of creating and using a test_client differs in any way? I don't like the nested "with" in the second method. First one seems more clear to me. Both of them works the same as far as I can tell... Are there any downsides of any of them or is this just a matter of preference?

1. ​

​

@pytest.fixture
def client():

app = createapp('../configs/testconfig.py')

with app.appcontext():
try:
db.createall() # I'm setting up the db for testing purposes here
yield app.testclient()
finally:
db.dropall()

2.

Why not Django?

Hi I am nodejs developer who get started this journey with Django. I have a task to make ai/machine learning model for production. As far as I know, 99% of people uses flask or fastapi as their choices. I want to know why and I am away from python world for a long time so I can’t even remember cli commands. I just want to know why and any resources or open source projects from you, thanks.

Google ads API not running on admin pod but is running on celery worker

So basically the title,

I am working on a project where I need to run a custom method in Django admin of some model, in this method I am acquiring a connection to the Google ads API and making a request to create something. While running this method in the admin pod, the process got stuck, but when I made a celery task it was fine and worked just as I expected, this is not the first project that this problem happened to our team, I couldn't find any explanation and I was wondering why did it happen, would love to get you insight on it.

miniloop: a minimal, pedagogical event loop implementation

https://github.com/roee30/miniloop

The PEPs introducing the async/await syntax don't specify exactly how event loops work, considering it an implementation detail. If you are curious about how event loops work in Python, you might have noticed that reading through asyncio's code is challenging, to say the least.

That's why I have created a minimal event loop implementation with step-by-step explanations. It shouldn't be used for anything other than learning purposes. It is 362 lines in size, but many of them are documentation. Before diving in, make sure you understand generators. You can use the server.py script to see the loop in action.

The implementation is inspired by asyncio, but I only added what was necessary in order to make a simple server work. In particular, my Task and Future are roughly analogous to asyncio's, but I didn't find a need to implement Handles (perhaps because I didn't implement the call_* methods).

I learned a lot writing this and I hope it will be useful to others as well.

Deploy Flask-app on IIS?

Hi all,

I have a simple Flask-app with the following structure that works fine locally on my machine:

\- app.py
\- static (folder)
\- scripts.js
\- styles.css
\- templates (folder)
\-index.html

app.py looks like this:

from flask import Flask, render_template

app = Flask(__name__)

# Ensure templates are auto-reloaded
app.config["TEMPLATES_AUTO_RELOAD"] = True

# Define the index page
@app.route("/", methods=["GET"])
def index():
resources = ['listhere']
instances = list(range(1,100))

# Add leading zero to first 10 digits
for i in range(9):
instances[i] = "0" + str(i + 1)

# Sort all lists just in case
resources = sorted(resources)

Django GraphDB

Hi everyone - never did a big Django project before but now I plan to start one which might grow in the future. It is an internal app and it will need to do some operations with Neo4j. My question is: is Django my best option or should I use another framework? I will need the basic admin over users etc but in terms of ""additional"" databases, I need to build a knowledge db with Neo4j (or any alternative graphdb). thanks in advance :)

pytest parametrize vs highly repetitive code?

In pytest ... or, for that matter, in the world of QA automation ... the coder is usually given the ability to parameterize variables that control the test cases. But at what point of adding successive parameters does this become overkill? What are your rules-of-thumb when deciding to write another test function or add a parameter (and perhaps an if-statement or more) to an existing test function?

I've always leaned toward the parameterize approach, only to, in the end, wish I hadn't made the primary test function so complicated and full of special-case if-statements. Having four or even eight nearly-identical test functions goes against the code-reuse theme that permeates s/w engineering. But sometimes code repetition is both easier to read and maintain - particularly in the domain of writing test automation.

Which one is preferred: self.state.adding VS not self.pk?

I'm going to do some checks before object is saved in DB and I just came across this:

if self.state.adding: # do something

which I never used before. I only used:

if not self.pk: # do something

are they functionally equivalent for identifying new model instances? Does one method have advantages over the other in certain scenarios? Seeking insights on best practices and functional differences, if any.

Which one is preferred generally?
