How to create thousands of records with factory boy?

# Issue

Let's say I'm running tests where I need to generate lots of data using factory\_boy and django orm like so:

class CompanyFactory(factory.Factory):
class Meta:
model = Company

name = factory.Faker('company')
email = factory.Faker('ascii_safe_email')
date_joined = factory.LazyFunction(datetime.datetime.now)

CompanyFacotry.create_batch(size=100_000)

**And this takes a lot of time to process.**

In the [factory\_boy docs](https://factoryboy.readthedocs.io/en/stable/reference.html#factory.CREATE_STRATEGY) it says, that \`create\_batch\` is using "create" strategy
I assume that it creates a bunch of save queries for each Company instance which impacts the performance.

# Solutions

* I found this factory\_boy [PR](https://github.com/FactoryBoy/factory_boy/pull/925) to implement a "true" bulk create. It has a lot of history and useful info on the subject but it seems to be stuck for now.
* There is [this article](https://www.rover.com/blog/engineering/post/speeding-django-test-runs-optimizing-factory-boy/) describing the solution which improves the performance but looks kinda hacky
* Also [this article](https://paul-grillenberger.de/2020/06/21/creating-test-data-with-faker-and-factory-boy/) besides describing basic faker/factory boy usage mentions this :

>The following method is appropriate for generating small- to medium-sized test

Built with Flask

Hello developers 👋👋


I built scenestamps.com and readtxt.in with flask. You can check it out and share your feedback on it.

TechStack :

- for scenestamps.com : flask, sqlite, html,css, js, bootstrap, NGINX

- for readtxt.in : flask,html,css, bootstrap, NGINX

Both deployed on digital ocean droplet(OS : Ubuntu).

This pretty much became my go to stack for prototyping & deployment. Quite simple and efficient, nothing fancy.

Hope this serves as one among many real world apps built using Flask. Flask just works.

Have a nice day.

I am trying to create an email that when clicked on and the token is filled in the form turns `registration_confirmation_email` to True from the default to False. Also I noticed the token is always the same.

I am testing the code when I click the resent token button. The error is located below.

I am testing the code when I click the resent token button. The error is located below.

The error is https://pastebin.com/bG6SYJUp or put simply itsdangerous.exc.BadSignature: No b'.' found in value. How do I solve the same exact token in every email and the error?


Here is the code.


**registration_verification_code.html** (uses bootstrap)


`{% if user_db.emal_token == None %}`, should be `{% if user_db.emal_token != None %}`

I even created this images which run through some of what can go right and wrong when I click resend email button.

how much python is too much python?

Context:
In my company I have a lot of freedom in how I use my time.
We're not a software company, but I care for all things IT among other things.
Whenver I have free time I get to automate other tasks I have, and I do this pretty much only with python, cause it's convenient and familiar. (I worked with RPA in the past, but that rquires a whole environment of course)

We have entire workflows syhcning databases from different systems that I put together with python, maybe something else would have been more efficient.

Yesterday I had to make some stupid graphs, and after fighting with excel for about 15 minutes I said "fuck it" and picked up matplotlib, which at face values sounds like shooting a fly with a cannon


don't really know where I'm going with this, but it did prompt the question:

Exception handling approach

Which is better?

Approach 1:

def fun1():
if ...:
raise Exception()
return ...

fun1()

def main():
try:
fun2()
except Exception as error:
...

if __name__ == "__main__":

Implementing MultiModal RAG Projects for PDFs with Critical Information in Tables

A common use-case of Python projects in production is for RAG applications. RAG deals with retrieval of relevant information from external data sources (often large in size) and combining them with user prompts to refine LLM responses.

Traditional RAG systems primarily use and parse text. But they often struggle with important details within tables. This hampers their utility in use-cases which demand reliability and accuracy such as RAG with Financial Documents. This is addressed with models like GPT-4o, Claude-3.5 Sonnet, LLaVA, which understand both text and images.

# Improving RAG accuracy for data in tables

Here we extract tables as images during the parsing process using GPT-4o, our choice of model for this blog with code. GPT-4o explains the content of the table in detail. Later it saves the table content with the document chunk into the index, making it easily searchable. The Pathway pipeline used here is scalable and great at incremental indexing – i.e. it becomes useful when there are any changes expected in the data stored within PDFs or tables.

# Architecture Used for Multimodal RAG for PDFs

This architecture must efficiently manage data ingestion, processing, and querying, while providing accurate and timely responses to user queries. Key components include

flpc: Probably the fastest regex library for Python. Made with Rust 🦀 and PyO3

With version 2 onwards, it introduces caching which boosted from 143x (no cache before v2) to \~5932.69x [max recorded performance on *my machine (not a NASA PC okay) a randomized string ASCII + number string\] (cached - lazystatic, sometimes \~1300x on first try) faster than the re-module on average. The time is calculated in milliseconds. If you find any ambiguity or bug in the code, Feel free to make a PR. I will review it. You will get max performance via installing via pip

There are some things to be considered:

1. The project is not written with a complete drop-in replacement for the re-module. However, it follows the same naming system or API similar to re.
2. The project may contain bugs especially the benchmark script which I haven't gone through properly.
3. If your project is limited to resources (maybe running on Vercel Serverless API), then it's not for you. The wheel file is around 700KB to 1.1 MB and the source distribution is 11.7KB

from capacitydata.allflash_dev group by name)
tm on t.name = tm.name and t.date = tm.MaxDate;




this is my code thats is working but showing all the lines.

class Block(db.Model):
    tablename = "allflashdev"
 
    index = db.Column(db.Date, nullable=False, unique=True, primarykey=True)

D Gave ML Framework Codesignal Test and beyond devastated!

I just gave the CodeSignal ML framework test after a lot of preparation, and it felt like I was trying way too hard to write ML algorithm code that I'm well versed with. I know the concepts in detail for all the algorithms, but writing two algorithms from scratch in 70 minutes, including one more coding task plus 6 MCQ questions and one output, is tough.

I'm not sure if it's just me facing this challenge or if it's common. It was very hard to recall all the functions (the logic is easy) to write the code in that stressful, proctored environment. How can I get better at this? I know practice, practice, practice, but even that didn't seem to help here. And I didn't find any practice materials to stimulate the same environment. If you know something please share.

Isn't this too much of an expectation? I'm just getting done with my PhD and at times, I feel like looking for a job is more stressful than it ever was (I have 5 years of experience). The expectations are too high. How are you all coping with such a rat race?

Need a buddy / mentor to work with and become good in django

Hello there. I'm a 3rd yr engineering student. I'm quite decent in python (i started off before my first year). later near the end of 1st year i picked up django, got grasp of the basics from YT.

At the start of 2nd year i picked up the book Django for Beginners By William vincent and got halfway through it but had to focus on academics to had to put it aside a bit. by the end of 2nd year i finished the book and got familiar with all the things like CRUD, Forms, User accounts, Password change/reset etc (although i'd need a quick recap cause its been a month or two since then). i did manually code side by side all the apps in the book and have it on my github so i have quite a good idea about how it works. but i think you cant really get the actual grasp of it unless you work on some real projects. Read that book like 2 times though

So i'm looking for someone who is good in django or is working on a project and is willing to mentor me while letting me help with the project too.

Hope you're
